IDENTIFICATION CODES

The Vehicle Identification Number (VIN) is a seventeen-digit alphanumeric code. The VIN is stamped on a metal tab riveted to the instrument panel, top upper left of the dash. The VIN number is also found on the Vehicle Certification (VC) label.

Vehicle Identification Number (VIN)

World Manufacturer Identifier (WMI)






The first three vehicle identification number (VIN) positions are the World Manufacturer Identifier (WMI) .


1FA - Ford, USA, passenger car
Restraint Type Code






The fourth VIN position is the vehicle restraint system type code.


F - Active safety belts - all positions, driver and front passenger air bags
Line, Series And Body Type Code






Positions 5 through 7 indicate vehicle line, series and body type.

Production Sequence Number






The last six VIN positions are the production sequence number. This number is also used as the vehicle serial and warranty number.


100001-599999

 

yes the last six digits are the production number but they are not that easy. A few numbers wouldnt be part of the actual production number.

Mine for instance 224113. There were not that many mustangs made total for 2005 so that cant be the actual production number. It might be 24113, which is realistic since i bought my GT in early 05 but i cant say for sure.

 

well dam lol

 

the last 6 of mine are 256221

 

The Saleen production number (found on the bumper typically) will be different than the last 3 digits on a VIN.

My guess would be those 6 digits could be overall production value (ie all models that year), but it's a guess.

 

Since there have been over 100,000 mustangs made each year, all 6 numbers are required to keep track of it. Where Ford decided to start the VIN #, is up to them. Its up to the manufacturers to determine the what, where, and how they do the numbering.

The Saleen number on the bumper is for Saleen and Saleen only. Nothing to do with the vehicle VIN.

 

Correct. The last 6 numbers are somewhat representative of where Ford is in their production line, based on the number they started production at. Just like when you go to a bank and start a checking account, you can start at 22,000 if you want to.

There are some manufactures that will start at zero, but not many
