Mileage inquiry is the process of accessing official records to verify a vehicle's mileage history at specific dates. It is critical in used car transactions as it provides essential clues about the engine, battery health (for electric vehicles), and overall condition. Verifying mileage is necessary for both internal combustion and electric vehicles to understand the true usage history and to detect potential fraud, such as odometer rollbacks.



What is Mileage Query?


Mileage query is the process of accessing official records that show how many kilometers a vehicle had at which dates in the past. This process is particularly critical in second-hand vehicle transactions because a vehicle's mileage provides important clues about the engine, battery health (in electric vehicles), usage intensity, and overall performance.


Today, verifying mileage for both internal combustion engine vehicles and electric vehicles (EVs) is essential for understanding the vehicle's actual usage history and detecting possible mileage rollback attempts.


Why is Mileage Query Performed?


The main reasons for conducting mileage queries:


  • Preventing fraud: A vehicle with rolled-back mileage can be sold for much more than its actual value.
  • Evaluating vehicle performance: In electric vehicles, high mileage is particularly important in terms of battery cycle count, SOH (State of Health), and range performance.
  • Understanding maintenance history: Periodic maintenance intervals for vehicles are determined based on mileage.
  • Accurate pricing in second-hand market: Enables comparison of information provided by the seller with official records.


What are the Mileage Query Methods in Turkey?


There are multiple official and quick methods for conducting mileage queries in Turkey. These methods are valid for both gasoline/diesel and electric vehicles.


Mileage Query via PTT / HGS


PTT displays mileage information recorded during bridge and highway crossings through past transit records.


  • Queries can be made with license plate numbers through PTT branches or PTT's online systems.
  • Particularly useful for electric vehicle users in verifying intercity travel history.


Mileage Query via 5664 SMS 


By sending an SMS to 5664, you can access the vehicle's TÜVTÜRK inspection mileage information.


  • Using the format "HASAR S LICENSE_PLATE", you receive mileage history and damage information.
  • Operator charges apply.


Mileage Query Through TÜVTÜRK Inspection Records


TÜVTÜRK records the vehicle's mileage information at each inspection entry.


  • This information can be viewed from TÜVTÜRK's official website or through e-Government integration.
  • In electric vehicles, the general condition of the battery is also observed at each inspection, making mileage information more critical.


Mileage Query via e-Devlet


e-Devlet, provides inspection dates and mileage information within the scope of "Vehicle Detail Query" service.


  • One of the most reliable query methods.
  • License plate + chassis number verification can be performed.



What Should Be Considered in Mileage Query for Electric Vehicles?

Mileage query in electric vehicles carries different importance because mileage directly affects the battery's usage cycles and health status.

EV users should definitely check the following points:


  • Mileage + battery health should be evaluated together: High mileage alone is not a negative condition; if the battery SOH value is above 80%, the vehicle still provides high performance.
  • Fast charging usage history: Intensive fast charging use combined with high mileage can affect battery life.
  • Consistency of service records with mileage: Maintenance mileages performed at official services should be consistent with query results.
  • Verification through license plate or chassis: In electric vehicles, since urban usage is typically intensive, mileage rollback attempts may be more common.




Frequently Asked Questions About Mileage Query


How can I learn a vehicle's mileage history?


Official mileage information can be accessed through TÜVTÜRK inspection records, e-devlet vehicle detail screen, PTT transit information, and 5664 SMS service.


How can a vehicle with rolled-back mileage be detected?


  • Inspection mileages don't match the sales mileage,
  • Mileage goes backward in service records,
  • Steering wheel and pedal wear are not consistent with mileage,
  • In electric vehicles, there is inconsistency between battery cycle count and mileage.


Is vehicle mileage query paid?


  • e-Devlet: Free
  • TÜVTÜRK: Free
  • PTT: May vary depending on transaction type
  • 5664 SMS: Paid (according to operator tariff)
