Reference number

Supplier reference numbers from Bosch, Hella, or others help when no OE is visible. They must not be confused with OE but are important for cross-reference. In German used-parts trade, Reference number is an everyday term. Recyclers should use it consistently in the team and ERP so search, eBay listings, and customer communication align. Technically correct maintenance saves inquiries and reduces returns. Document relevant attributes in structured fields instead of free text only. Train new staff specifically on this term, especially at vehicle intake and part capture.
