When buying a used Tesla part, the most reliable starting point is the exact OEM part number. Tesla components can look nearly identical while differing by revision, side, connector, vehicle configuration, or production period.
What is a Tesla OEM part number?
An OEM part number is the manufacturer identifier printed or labeled on the original component. It often appears in a format such as 1044831-99-D or 1500397-00-E. The final letter or revision can matter, so buyers should compare the complete identifier whenever possible.
Where to look for the number
- Printed labels or stickers on the component
- Molded or stamped markings on housings
- Labels on electronic modules and wiring harnesses
- Documentation from the removed vehicle or repair estimate
Why exact matching matters
A part may fit only certain production periods, trims, motor configurations, left/right positions, or hardware revisions. A matching model name alone is not enough. Compare the complete OEM number and, when needed, confirm compatibility using the vehicle VIN and build date.
