What is an OEM Part Number?
An OEM part number is the unique alphanumeric identifier an original equipment manufacturer assigns to a specific part or component. Buyers use it to find and order replacement parts that match the original, and companies use it to track parts across catalogs and inventory systems.
OEM Part Numbers and PIM
A PIM stores and maintains OEM part numbers alongside descriptions, specifications, and pricing, so the same part data appears consistently on eCommerce sites, printed catalogs, and point-of-sale systems. That cuts errors and keeps inventory data reliable.
Example: An automotive parts retailer could manage thousands of OEM part numbers in a PIM and use workflows to:
- Update OEM numbers when manufacturers change or supersede parts
- Map each OEM number to the retailer’s internal SKUs
- Validate part numbers and flag missing or duplicate values
- Connect OEM numbers to vehicle fitment data
- Distribute approved part data to every sales channel
This helps staff find the right item and helps customers find parts that fit their vehicle.
Synonyms: Original Part Number, Factory Part Number, OE Number
