Odometer Disclosure Statement: Reading It for a Rollback

The federal odometer form is a certification with two escape hatches, and on the overwhelming majority of used cars both hatches are left shut. Appendix B to 49 CFR Part 580 sets out the wording states have to put on a title, read on the eCFR on 29 September 2026: "I state that the odometer now reads ______ (no tenths) miles and to the best of my knowledge that it reflects the actual mileage of the vehicle described herein, unless one of the following statements is checked."

Look at the grammar of that sentence rather than the blank in the middle of it. The certification is the default. Writing a number down is itself the sworn claim that the number is true, and the only way out of it is to tick one of two boxes printed underneath. Almost nobody ticks them. So the ordinary condition of a used car's paperwork is a chain of people, each of whom formally certified that the mileage was real, at least one of whom may have been wrong.

Which is why a rollback is rarely something you find by looking at a dashboard. You find it in the sequence: in two documents that cannot both be true, in a box checked once and then quietly dropped, in a power of attorney that federal law has already declared void and somebody used anyway. This is a piece about reading that sequence. The mechanics of signing a title in a private sale sit in the private-sale paperwork guide and are not repeated here.

Two boxes, and why the first one contradicts most modern dashboards

Part 580 gives the transferor exactly three positions, at section 580.5(e). Certify that the reading reflects actual mileage. Or state that the reading "reflects the amount of mileage in excess of the designed mechanical odometer limit." Or state that the reading "does not reflect the actual mileage, and should not be relied upon."

Those map onto the printed boxes in Appendix B:

Box 1 is the interesting one, because on most cars sitting on a 2026 lot it cannot honestly be used. Florida's separate form HSMV 82993 prints the limitation inside the box itself: "IS IN EXCESS OF ITS MECHANICAL LIMITS.(EXCESS OF ITS MECHANICAL LIMITS APPLIES TO 5 DIGIT ODOMETERS)". The same form's disclosure block opens "WE STATE THAT THIS 5 or 6 DIGIT ODOMETER NOW READS", so the state is asking you to say which kind you are looking at. A five-digit mechanical odometer tops out at 99,999 and rolls over. A six-digit display does not reach its ceiling until 999,999. Box 1 ticked on a car showing 84,000 miles on a six-digit cluster is not a disclosure of rollover. It is either an error by whoever filled the form in, or a way of writing "this number is not right" without writing the word discrepancy.

Box 2 carries an obligation people skip past. Under section 580.5(e)(3) the not-actual-mileage statement "shall also include a warning notice to alert the transferee that a discrepancy exists between the odometer reading and the actual mileage." That is why the printed form shouts. The drafters wanted the mark to be impossible to miss, because the entire enforcement design depends on it surviving every later transfer.

The rollback tripwire written into the power-of-attorney rules

This is the part of Part 580 that almost nothing in the consumer literature mentions, and for a buyer it is the most useful thing in the regulation.

Sometimes the seller cannot sign the title, because a lender is holding it. Section 580.13(a) allows a power of attorney for mileage disclosure in four situations and no others: the physical title is held by a lienholder, the physical title is lost, the electronic title is held or controlled by a lienholder, or the electronic title cannot be accessed. The seller discloses the mileage on the state's power-of-attorney form, the buyer signs it, and when the title finally arrives the buyer writes the mileage onto the title "exactly as the mileage was disclosed by the transferor."

Then comes the tripwire, section 580.13(g), quoted at length because the sentence is the whole point:

If the mileage disclosed on the physical or electronic power of attorney is lower than the mileage appearing on the physical or electronic title, the power of attorney is void and the transferee shall not complete the mileage disclosure on the title unless: (1) The transferor has included a statement that the mileage exceeds mechanical limits; or (2) The transferor has included a statement that the odometer reading does not reflect the actual mileage.

Federal law has built a one-way ratchet into the paperwork. Mileage may go up. If it goes down, the instrument is dead on arrival, and the only way to revive it is to tick a box that announces the problem in capital letters.

Section 580.15 then makes somebody sign their name to that arithmetic. Where a jurisdiction uses the full form, Part C is a certification by the person who exercised powers of attorney under both section 580.13 and section 580.14, and it certifies two things: that the mileage put on the title matches what the power of attorney said, and that the figure "is greater than that previously stated on the physical or electronic title and applicable physical reassignment documents." Appendix E prints the sentence a dealer's title clerk actually signs. Subsection (c) repeats the kill switch: if the figure is less than what was already on the title, the power of attorney "shall be void."

Two practical consequences fall out of this.

• A power-of-attorney disclosure on a car whose title was neither held by a lienholder nor lost sits outside section 580.13(a) from the start. If there was no loan on the car, ask why the form exists.
• Part C is a dated, signed, addressed certification by a named individual that the mileage went up. If a descending sequence exists anywhere behind it, that person's signature is attached to it.

And you are allowed to look at the layer underneath. Section 580.16(b): on a transferee's request, a transferor who was granted a power of attorney and who now holds title in their own name "must show to the transferee the copy of the previous owner's title and the physical or electronic power of attorney form." That is a right to see the document behind the document, and in practice nobody exercises it.

Who has to keep the copy, and for how long

The paper does not evaporate when the sale closes. Four retention rules run for five years each, and each names a different holder.

Read that first row twice. Issue and receive. The statement a dealer issued is the one in your folder. The statement they received is the one their own seller handed them, and it is the document that would show what the car read before their lot ever touched it. A dealership that sold a car two years ago is still inside the five-year window for both halves of the pair.

The auction record in section 580.9 is narrower but in one respect better: it is a reading tied to a specific date on which a commercial party physically took possession, independent of whatever anybody certified to anybody. Wholesale auction is exactly where cars change hands between regional markets, and it is a step that leaves no trace in a title chain.

Note what is absent from all four rows. There is no federal retention duty on a private seller. The stack on a private-party car is whatever that individual happened to keep in a drawer.

The exemption arithmetic that changed on 1 January 2021

Section 580.17 lists who does not have to disclose at all:

• a vehicle with a Gross Vehicle Weight Rating of more than 16,000 pounds;
• a vehicle that is not self-propelled;
• a model year 2010 or earlier vehicle transferred at least 10 years after 1 January of the year corresponding to its model year;
• a model year 2011 or later vehicle transferred at least 20 years after 1 January of the year corresponding to its model year;
• a vehicle sold directly by the manufacturer to a United States agency in conformity with contractual specifications.

Subsection (b) adds new vehicles before their first transfer for purposes other than resale, which is why a new car arrives with a Monroney sticker and not a disclosure form. The regulation supplies its own worked examples, which is unusually helpful of it: "For vehicle transfers occurring during calendar year 2020, model year 2010 or older vehicles are exempt," and "For vehicle transfers occurring during calendar year 2031, model year 2011 or older vehicles are exempt."

For a transfer happening now, the arithmetic collapses to one line. Model year 2010 and older: exempt, no disclosure required, no federal mileage record being created at transfer. Model year 2011 and newer: not exempt, and the earliest of them does not become exempt until 2031. There is no car on the road today for which the twenty-year clause has run out. So on a 2011-or-newer vehicle, a missing mileage disclosure is not an age exemption. It is a missing document.

The dates behind that split are worth knowing, because the change nearly landed a year earlier than it did. The 2019 final rule, 84 FR 52664, moved the exemption point from ten years to twenty as part of the same rulemaking that authorised electronic odometer disclosure under MAP-21. The American Association of Motor Vehicle Administrators and the Delaware Department of Transportation both petitioned for reconsideration, asking for a one-year delay so that states and systems could catch up, and NHTSA granted it in 84 FR 65017, published 26 November 2019: "The increase in the exemption period to twenty years will now come into effect on January 1, 2021 and will apply to model year 2011 and later vehicles." Cars transferred during calendar 2020 were the last cohort to run on the old ten-year rule.

NHTSA's own consumer page compresses all of this into a single clause. A vehicle is exempt "if it's 20 years old or older, or a model year 2010 vehicle or older." That lands in the right place today, but it is a paraphrase of a rule pinned to 1 January of the designated model year, and states word it differently again. If you are arguing about a specific car near a boundary, argue from section 580.17 rather than from anybody's summary of it.

There is one more reason the ten-to-twenty change matters, and it comes out of NHTSA's own data rather than the rule. Table 2-10 of the agency's 2002 technical report, headed Rate of Odometer Fraud by Vehicle Age, puts the rate at 0.06 percent at age one, then 0.50, 0.54 and 0.58 percent at ages seven to nine, and 0.67 percent at age ten — the highest figure in the table, and more than ten times the age-one rate. Under the old regime, disclosure switched off at year ten. Put the two documents side by side and the exemption expired at very nearly the age at which the measured fraud rate topped out.

Two cautions about reading that table. Its age-11 row shows 0.00 percent because the study window closes there, not because fraud stops. And Table 2-11, which is the one that sums to the headline 3.47 percent, carries a lower-looking set of figures for the same ages — 0.45, 0.47, 0.49 and 0.54 percent at ages seven to ten — because each rate there has been multiplied by the share of vehicles still on the road at that age. Those are survival-weighted contributions to a lifetime total, not the chance of fraud on a car of that age, and quoting them as rates understates the curve. The reading of the boundary is mine rather than a stated agency rationale, but both numbers are public and the boundary was in the rule.

Where the mileage figure stops travelling

A disclosure only helps you if it ends up somewhere you can reach. The federal title system's reach is set by one conditional clause.

Under 28 CFR 25.54(a), each state supplies NMVTIS with the VIN, the title description including all brands, the name the certificate was issued to, junk and salvage acquisition information where the state collects it, and, at paragraph (a)(5), "the odometer mileage disclosure required under 49 U.S.C. 32705 for that automobile on the date the certificate of title for that automobile was issued and any later mileage information, if noted by the state." The same conditional appears in the system design requirement at 28 CFR 25.53(b)(4).

One snapshot per title issuance is compulsory. Everything else is discretionary. A car with three owners across three states has three mandatory readings and whatever each of those states chose to add. There is nothing in there from the years in between.

What the rules do compel is a comparison at the state border. Section 25.54(c) requires a state, before issuing a title on a car titled elsewhere, to run a check through NMVTIS and use the result "to compare and verify the odometer information presented with that reported in the system." That is a federal obligation landing on a clerk, and it is the single most reliable rollback check anyone routinely performs on a used car. It is also why an interstate move is simultaneously where a rollback is most likely to be caught and where the trail is most likely to break. The same fault line runs through brands; how a title label survives a state line is the companion problem.

Then there is the disclosure that never reaches a state at all. Appendix C to Part 580 is the separate form, used when the mileage cannot be disclosed on the title itself. Florida's version of it, HSMV 82993, says under FILING: "IT IS NOT NECESSARY TO FILE THIS FORM OR ANY COPY OF THIS FORM WITH THE STATE OF FLORIDA, UNLESS REQUESTED TO DO SO BY THE DIVISION OF MOTORIST SERVICES," directly alongside "DEALERS MUST RETAIN THIS DOCUMENT IN THEIR RECORDS FOR A PERIOD OF FIVE YEARS." So the document exists, a dealer holds it for five years, and the state, and therefore the federal system, and therefore any report you can buy, may never see the number written on it.

I went looking for the other end of this, the state record sitting behind a figure a report displays, and got a partial answer. Wisconsin's form MV2896 is the request for a vehicle record and offers a history of all owners at five dollars per owner. What the form does not state is whether the resulting abstract carries prior odometer readings; it says only that a history request "will include each record/owner." It also puts the access question ahead of the data question: "It is the responsibility of the requestor to determine if they qualify for the information and uses permitted under the listed Federal Acts." Read on 29 September 2026. So the honest version is that the state which reported a figure is the right place to ask for the underlying record, the first hurdle is a permitted-use declaration rather than a fee, and what comes back varies by state in a way I could not establish from the form. For what a purchased report does and does not contain, the NMVTIS walkthrough goes through the five indicators line by line.

What a rollback looks like in a stack of paper

The sequence below is constructed to show the shape, not taken from a specific car. Each row is the kind of entry that turns up on a title, on a reassignment document, or on a report.

Four separate things are wrong there, and each one is checkable against a section number.

1. The sequence descends. 118,900 in early 2024, 62,300 six months later. Under section 580.13(g) a power of attorney disclosing a figure lower than the title's is void, and under section 580.15 somebody had to certify the opposite of what happened.
2. A discrepancy mark appears and then vanishes. Box 2 was ticked in March 2024 and the September title reads as a clean actual-mileage certification. That mark is meant to ride forward.
3. The state crossing coincides with the drop. State A to State B, at the same step the number fell. Section 25.54(c) required a comparison at exactly that point.
4. The power of attorney needs a reason to exist. Section 580.13(a) permits one only for a lienholder-held title, a lost title, or an inaccessible electronic title. Dealer-to-dealer convenience is not on that list.

Now the version that is harder. Delete rows three and four. A car titled in 2022 at 71,480 and retitled in 2024 at 62,300 still descends, and a descent between two titles is still visible to anyone who lines the readings up. But a car rolled back between titlings, with no auction, no reassignment and no state crossing, produces a single pair of readings 27 months apart with a plausible number in the second slot. Nothing in Part 580 and nothing in NMVTIS sees that. That case gets closed by service invoices, inspection records and the physical condition of the car, which is where an independent pre-purchase inspection earns its fee, and where the dated tire and glass markings covered under the repaint checks give you components to compare against a mileage claim.

Security features are the reason an altered title looks altered

NHTSA's consumer advice includes a line most people read as vague: examine the title closely "if the mileage notation seems obscured or is not easy to read." It is not vague at all. It is pointing at a design requirement.

Section 580.4(a) requires every physical title, and every reassignment document and power of attorney, to be produced by "a secure printing process or other secure process." Section 580.3 defines that term as any process which "deters and detects counterfeiting and/or unauthorized reproduction and allows alterations to be visible to the naked eye." Appendix A then lists the methods in two groups. Against counterfeiting: intaglio printing, intaglio with latent images, high resolution printing, micro-line printing, a pantograph void feature, holograms, and security paper carrying a watermark or thread. And in the second group, the features aimed squarely at somebody editing a number that is already on the page: "Erasure Sensitive Background Inks—a process whereby the text is printed in a dark color ink over a fine line erasure-sensitive prismatic ink tint," security lamination "placed over vital information after it has been entered to allow for detection of attempts to alter this information," and paper chemically treated to reveal chemical alteration.

So the mileage field on a title sits on a background engineered to smear, lift or discolour if anyone works on it. Tilting the document under a light is a regulated feature doing its job, not folk wisdom.

The electronic equivalent is an audit log. Section 580.4(b) requires a state's system to record the dates and times when an electronic document is created, when the odometer disclosures inside it are signed, and when the documents are accessed, "including the date and time any unauthorized attempt is made to alter or modify the electronic document and any unauthorized alterations or modifications made." Section 580.3 defines access to mean entry that allows modification of stored data, even where nothing was in fact modified. And where a paper document has been scanned into an electronic record, section 580.6(h) requires the security features to survive the conversion and sets a floor of "not less than 200 dpi." Whether a given state will show a consumer any part of that log is a state question I cannot answer generically. The log has to exist.

What a wrong number is worth, and the clock running on it

The private remedy here is unusually generous by consumer-protection standards, and unusually short.

49 U.S.C. 32710(a) makes a person who violates the odometer chapter with intent to defraud liable for "3 times the actual damages or $10,000, whichever is greater." That statutory floor was $1,500 until MAP-21 raised it in 2012, and the figure is inflation-adjusted in the penalty regulation: 49 CFR 578.6(f)(2) states the amount as "three times the actual damages or $13,676, whichever is greater," read 29 September 2026. Section 32710(b) then adds the part that decides real cases: "The action must be brought not later than 2 years after the claim accrues. The court shall award costs and a reasonable attorney's fee to the person when a judgment is entered for that person."

Two years, with fee-shifting. The fee-shifting is why a lawyer will look at a matter worth only thirteen thousand dollars. The two years is why the matter often never gets looked at, because the event that reveals the problem is frequently a repair bill arriving in year three.

The government's side of the ledger, for scale:

The underlying prohibitions sit at 49 U.S.C. 32703, and one of them is broader than people expect. It is a violation, with intent to defraud, to "operate a motor vehicle on a street, road, or highway if the person knows that the odometer of the vehicle is disconnected or not operating." Driving the car is the offence there, not only selling it.

NHTSA publishes its own enforcement record on the odometer fraud page: office investigations have produced "more than 250 criminal convictions in more than 30 states," prison sentences ranging from one month to ten years, criminal fines totalling more than $2.8 million and court-ordered restitution more than $15 million. Large-scale schemes go to the Vehicle Safety Hotline at 888-327-4236. An individual case goes to your state enforcement agency, and the agency says plainly that it has no authority to pursue claims on a consumer's behalf and that consumers should consult a private attorney about their remedies.

The federal numbers everyone quotes come from a 2002 preliminary report

Every odometer-fraud statistic in circulation traces back to one document, and it is worth knowing which one. NHTSA's page says "more than 450,000 vehicles are sold each year with false odometer readings" and puts three figures in a sidebar. All three cite DOT HS 809 441, Preliminary Report: The Incidence Rate of Odometer Fraud, dated April 2002.

The report's executive summary gives approximately 452,000 cases per year; an average overpayment of $2,336 per case, being the gap between what buyers paid and what they would have paid knowing the true mileage; and "$1,056 million per year (confidence bounds from $737 million to $1,376 million)." It puts the chance of fraud over a vehicle's first eleven years at 3.47 percent. The report expressly excludes inflated financing, insurance and tax, subsequent repair costs, and lost resale value from that total, so the figure is a floor by its own account.

Two cautions, both of which matter more than the headline.

First, the sidebar on NHTSA's live page renders the annual total as "$1.06M". The report it cites says $1,056 million. The real figure is a thousand times larger than the page implies. If you are quoting a number, quote the report.

Second, 2002 was before digital instrument clusters were universal, and NHTSA's own page concedes the consequence: digital odometers "that have been tampered with are even harder to detect than traditional mechanical odometers (since they have no visible moving parts)." A rate estimated on mechanical dashes describes a different market from a lot full of cars whose mileage is stored in more than one module. Treat the 2002 figures as the shape of the problem rather than its present level. Nothing newer is published, which is itself worth knowing when a listing or a report cites the 450,000 number as current.

The same report also measured the states, and that part has aged into a warning rather than a statistic. Only four states had taken all three of the detection steps the study identified: routinely verifying odometer readings submitted by title applicants, alerting the titling office or the applicant when a car is being titled with a lower mileage than a previous title, and keeping odometer readings at times other than titling, such as at annual emissions or safety inspections. "Fewer than ten states routinely notified law enforcement agencies when the odometer reading shows signs of alterations on the title being surrendered." Those findings rest on a questionnaire sent to state motor vehicle offices in October 1997 and returned by forty-six states, the District of Columbia and Puerto Rico, so they are twenty-nine years old, and state systems have changed a great deal since, including the arrival of the mandatory NMVTIS comparison in 28 CFR 25.54(c). But they explain why the descending-sequence check has historically fallen to whoever bothered to look, and why it is worth being that person.

The request that costs nothing and almost nobody makes

Three sentences, in this order, before money moves on a 2011-or-newer car.

May I see the title, including the mileage block, in person and in the light. May I see the odometer disclosure statement you received from your seller, the one section 580.8(a) keeps for five years. And if a power of attorney was used anywhere in the chain: may I see it, plus the previous owner's title, which section 580.16(b) says a transferor holding title in their own name must show on request.

None of the three costs anything. None of them requires a tool, a subscription or an appointment. What they get you is the one thing a purchased report cannot supply on its own: the documents behind the data points, in an order you can read, with the names of the people who signed each one. If the answer is that the paperwork cannot be produced, you have not proven fraud. You have established that the car's mileage rests entirely on the word of the person selling it, which is exactly the position the disclosure rule was written to get buyers out of.

Federal text quoted here was read on the eCFR and on government mirrors of the U.S. Code on 29 September 2026. Part 580 has been amended repeatedly, most recently in the 2019 electronic-disclosure rulemaking, so check the section before relying on a quoted sentence in a dispute.
