Not Actual Mileage Title — Many Causes, One Brand.
A not actual mileage title means the odometer reading cannot be trusted as the car's true mileage. It does not say why. A replaced cluster, a missing form and verified tampering can all end in the same brand, and every state words it differently.

Quick Answer
- What does not actual mileage mean on a title?
- Someone has recorded that the number on the odometer is not the car's true mileage. Under federal rules it is one of three statements a seller can sign, and it carries the words “WARNING—ODOMETER DISCREPANCY”. The brand says the number is wrong. It does not say by how much, or why.
- What do TMU and exceeds mechanical limits mean?
- Exceeds mechanical limits means the odometer rolled past the highest number it can show, so the true mileage is higher than the reading. TMU stands for true mileage unknown. Of the 48 states whose wording we read, only Connecticut prints it on titles, where it means no mileage was submitted with the title application.
- Should I buy a car with a not actual mileage title?
- It depends on why the brand is there. A replaced instrument cluster and verified tampering can end in the same brand. Run the VIN to see every reported reading and the national brand code behind the title. Our full report is $14.99.
How a mileage brand ends up on a title
Two records sit behind every mileage brand: the national code, and the words one state chose to print. They do not always carry the same detail.
- 1The seller signs a mileage statementFederal rules give three choices: the reading is the actual mileage, it exceeds the odometer's mechanical limits, or it is not the actual mileage.
- 2Something does not add upA reading lower than an earlier record, a replaced cluster, a dead display, or a transfer with no properly completed disclosure at all.
- 3A national code is recordedThe federal title system has separate codes for not actual, tampering verified, may be altered, replaced, discrepancy, exempt and exceeds mechanical limits.
- 4The state prints its own wordingTexas writes Not Actual Mileage, California prints the letter N, Pennsylvania uses status code 2 or 3. Same history, different words on the paper.
- 5The brand follows the carOregon says a not-actual brand cannot be removed. When the car is retitled elsewhere, the new state converts the brand into its own wording.
What “Not Actual Mileage” Tells You, and What It Leaves Out
Every time a car changes hands, federal rules make the seller sign one of three statements about the odometer. The reading is the actual mileage. Or it reflects mileage beyond the odometer's mechanical limits. Or it is not the actual mileage and should not be relied upon, followed by a warning that a discrepancy exists. The federal form prints that last one as “NOT the actual mileage. WARNING—ODOMETER DISCREPANCY.”
Once that third statement is made, or a state finds reason to doubt the reading on its own, the title carries a mileage brand. The brand tells the next buyer one thing: do not price this car on the number in the dash. It says nothing about the true figure, which might be a few thousand miles higher or far more.
It also says nothing about the cause, and the causes range from harmless to criminal. That is why the same four words can sit on a car you should walk away from and on one you can buy with the right paperwork. The detail you need is in the record behind the title, not on the title itself.
Four roads to the same brand
- The odometer was replaced or repaired. Georgia applies not actual mileage to broken and repaired odometers, so a warranty cluster swap can earn the same brand as a rollback.
- The owner was not sure. California's N covers a broken odometer, a replaced one, or an owner who is unsure of the true mileage.
- The paperwork was missing. Texas writes Not Actual Mileage by default when no properly completed disclosure arrives with the title application.
- Someone rolled it back. Pennsylvania keeps status code 3 for cars where the state has verified tampering, and the national system has its own code for it.
The Eight National Odometer Codes, and What Texas Prints for Each
States report mileage brands to the federal title system under national codes. The definitions below are the ones the Texas DMV publishes, next to the brand a Texas title shows for each code. Five different codes come out as the same Texas words.
Actual
The mileage is true for the vehicle.
Not Actual
The odometer reading is known to be other than the true mileage.
Not Actual – Tampering Verified
The reading is known to be other than the true mileage because of tampering.
Exempt
The vehicle can change owners without an odometer disclosure.
Exceeds Mechanical Limits
The reading is lower than the true mileage because the odometer cannot display it all.
Odometer May Be Altered
The titling authority has reason to believe the odometer was altered.
Odometer Replaced
The odometer is not the one fitted when the vehicle was built.
Odometer Discrepancy
Earlier recorded readings give the titling authority reason to doubt this one.
There is one more code, 77, Call Title Division: the titling authority knows of a problem with the reading that it cannot print on a title. Texas sends anyone holding one to a TxDMV Regional Service Center. If you see it, ask the state before you ask the seller.
See the Code Behind the Brand
A Texas title says Not Actual Mileage for five different reasons. Enter the VIN for a free preview, then read the national code and every reported reading in the full report.
How the Brand Reads on Six States' Titles
We read odometer wording for 48 states from their own statutes, DMV pages and forms. For 28 of them the wording is confirmed as printed on the certificate itself. A buyer scanning for the phrase “Not Actual Mileage” will miss it in several of these.
Five national codes print as this one brand, and Texas writes it by default when the disclosure is missing.
A single letter beside the mileage: A for actual, E for exceeds mechanical limits, N for not actual. Titles issued since 18 April 1994.
A digit, not a phrase. Code 2 is the ordinary warning; code 3 means PennDOT has verified tampering.
Printed on the front of the title, away from the brand box. Mileage is not one of New York's formal brands.
Typed by the county clerk of courts after the mileage, in the exact words the statute sets.
One of four legends. It means no mileage was submitted with the title application, not that the reading is false.
The wording for every state we could verify, with the form and statute behind it, is on our odometer rules by state pages.
Exceeds Mechanical Limits, TMU and the Other Legends
Exceeds mechanical limits is not about a false reading. It means the odometer ran out of digits and started again, so the car has covered more miles than the dash shows. Georgia keeps the brand for a genuine roll-over past 99,999 on a five-digit odometer or 999,999 on a six-digit one.
Florida gives the clearest example. A five-digit odometer showing 24,000 on a car written up as “124,000 actual” is, to Florida, a paperwork error to be corrected to “24,000 Exceeds Mechanical Limits”, not evidence of a rollback. The miles are real. They just do not fit on the display.
So an exceeds-mechanical-limits car is usually an old, high-mileage car with honest paperwork. The question to ask is how many times the odometer has gone round, and the dated readings in a history report are the easiest way to answer it.
Florida bans two shortcuts
Writing “true mileage unknown (TMU)” or “exceeds true mileage (ETM)” on a Florida disclosure violates state and federal law, and the paperwork must be rejected. Connecticut, by contrast, prints true mileage unknown as an official legend.
TMU, exempt and not readable
Three more legends that look like mileage warnings but answer narrower questions. Read each one for what it says, not what it sounds like.
True mileage unknown
Connecticut splits mileage into four legends. Its true mileage unknown is the weakest: no mileage was submitted when the title was applied for. Its not actual mileage means the reading could not be determined at all. Neither one accuses the seller of anything.
Exempt
Nobody certified the mileage because federal rules did not require it: model year 2010 and older once 10 years past, 2011 and newer once 20 years past, plus trucks over 16,000 lb GVWR. Pennsylvania will not carry another state's exempt brand on a 2011-or-newer car; it records the reading under status code 2.
Not readable
Oregon's fourth status, for a digital odometer with a blank display. A dead cluster on an ordinary car earns it. Oregon says the brand cannot be removed, and that a serviced odometer set to zero needs a repair notice on the left doorframe.
Should You Buy a Car With a Mileage Brand?
Start with the cause, because it decides everything else. An odometer replaced under warranty, with a dealer invoice showing the reading on the old unit, leaves a paper trail back to the true mileage. A car where the state verified tampering leaves you guessing, and Pennsylvania's code 3 or the national tampering code is the point to stop.
In between sit the missing-paperwork cases. In Texas, a transfer without a properly completed disclosure produces the same brand as a real mileage problem, so the brand alone cannot tell you which one you are looking at. The reported readings usually can: a smooth climb from year to year points one way, and a drop points the other.
Whatever the cause, price the car on the higher mileage you can reasonably assume, not on the dash. And remember that you will be selling a branded title too. In Oregon the brand cannot be removed, and a buyer after you will see the same four words you are reading now.
Ask the seller for
- The invoice for any odometer or cluster replacement, with the old reading
- Service and inspection records showing mileage over the years
- The disclosure statement from the last transfer
- Why the brand is there, in their own words
What the Full Report Adds to the Title
The title gives you one state's wording. The report gives you the readings and the national record behind it.
Every reported reading, in order
Each odometer reading on record with its date, the mileage, where it was reported and the source. A reading lower than an earlier one stands out.
The national brand code
Title brand records are listed by their national name and code, which can say more than one state's wording on the title: replaced, may be altered or tampering verified.
The other title brands
Salvage, rebuilt, flood and buyback brands sit in the same section. A mileage brand on a car with a salvage past is a different conversation.

How to Check a Mileage Brand Before You Buy
Record, title, car. The Texas DMV's own buyer checks cover the last two.
Run the VIN and read the timeline
Look for any reading lower than one before it, and for a gap of years with no readings at all. Then look for the national odometer code in the title brand section.
Find the mileage box on the title
Each state prints it differently: a phrase in Texas, a letter in California, a digit in Pennsylvania. On a New York title it sits away from the brand box.
Match the car to the paperwork
Compare the odometer with inspection records and oil-change stickers on the windshield, door frames or under the hood. On a mechanical odometer, crooked or loose digits are a warning sign.
Check the wear against the miles
TxDMV's rule of thumb: an odometer reading 20,000 miles or less should still have the original tires. Worn pedals on a low-mileage car deserve a question.

Not Actual Mileage Titles — Frequently Asked Questions
What the mileage brands mean, how states word them, and what to do before you buy.
What does not actual mileage mean on a title?+
It means someone has recorded that the odometer reading is not the car's true mileage. Federal rules give a seller three statements to choose from: the reading is the actual mileage, it exceeds the odometer's mechanical limits, or it is not the actual mileage and should not be relied upon, which comes with the warning ODOMETER DISCREPANCY. The brand tells you not to trust the number. It does not say how far off it is or why.
What does exceeds mechanical limits mean on a title?+
The odometer has rolled past the highest number it can display, so the car has covered more miles than the reading shows. Georgia keeps the brand for a roll-over past 99,999 on a five-digit odometer or 999,999 on a six-digit one. Florida treats a five-digit odometer showing 24,000 on a car written up as 124,000 actual as a paperwork error to be corrected to 24,000 exceeds mechanical limits, not as a rollback.
What does TMU mean on a car title?+
TMU stands for true mileage unknown. Of the 48 states whose odometer wording we read, only Connecticut prints it as a title legend, where the DMV defines it as mileage not submitted when the title was applied for. Florida goes the other way and bans the abbreviation on disclosures altogether, so the phrase you see depends on the state.
What does exempt mean in the mileage box of a title?+
The car changed owners without an odometer disclosure because federal rules exempted it. A model year 2010 or older car is exempt once it is 10 years past 1 January of its model year, and a model year 2011 or newer car once it is 20 years past. Trucks over 16,000 pounds GVWR and vehicles that are not self-propelled are exempt too. An exempt title does not say the mileage is wrong. It says nobody certified it.
Can a not actual mileage brand be removed from a title?+
Not in Oregon, where the DMV states that a not actual or not readable brand cannot be removed. Pennsylvania adds a related rule: once an owner elects exempt, there is no way to return the record to true mileage. Treat a mileage brand as permanent unless the titling state says otherwise in writing.
Why do different states word the brand differently?+
Each state prints its own legend. Texas writes Not Actual Mileage, California prints the letter N, Pennsylvania uses an odometer status code, New York prints a long phrase ending in WARNING ODOMETER DISCREPANCY, and Ohio's clerk of courts types nonactual followed by a colon. Texas also folds five different national codes into its one brand, so the national code in a history report can say more than the title.
Does your report show odometer brands?+
Yes. The full report lists every odometer reading reported for the VIN with its date, location and source, and lists title brand records by their national name and code, including not actual, tampering verified, odometer replaced, exempt and exceeds mechanical limits. It shows what was reported, so compare it with the title and the car itself.
