Decoding Nissan Part Numbers
Other Names: Understanding Nissan Part Numbers
Models: GTR, GTST, GTS, Other
From 1980 forward, Nissan has been using a 10 digit alphanumeric character sequence for its part numbers. These 10 characters are broken up into 4 groups as follows:
149 – Section
50 – Character
26E – Part Type
01 – Distinction
The first 3 characters make up the Section Number and tells you the part’s major function or use. As an example, “149” would mean it is a part of the “Air Pollution Control” section. If the very first character is a letter, you can substitute the letter for the letter’s number in the alphabet (A is 1, B is 2, C is 3, 4 is 5, etc). Both the Section Number and Character number are used in conjunction.
The Character Number consists of two characters and is used to divide the above major functions or uses into smaller classifications. This is to say that the Character numbers show the more specific classification within the bigger function of the Section Number.
The Part Number is made up of 3 characters and tells you what model Nissan the part was originally designed to fit when it was first created. The part may fit other later models, but again, the number only indicates the original application.
The last 2 characters show the changes or differences between similar parts. This could show the difference in colors of trim pieces or material as an example. There are 4 major categories of distinction:
Similarity – Slight differences in parts (Ex: Color): 00-19 and 60-69
Service – Assigned to service kits (Ex: Brake master cylinder
seal kits): 25-29 and 75-79
Material – Differences in material during manufacturing: 40-45 and 80-85
Processing – Indicates the assembly line procedures differ from service procedures (Ex: Use of sub-assemblies versus fully assembled components): 30-39 and 90-94 and 50-59
