Why fitment is the bottleneck
A part without fitment data is a part nobody can safely buy. Building those vehicle lists by hand is the slowest step in listing a parts catalogue, so Huup attaches them from a vehicle database instead of asking you to assemble them per SKU.
References
- OEM references — the manufacturer's own part numbers, the most reliable route into fitment.
- Aftermarket references — supplier and brand numbers for the same part.
- Equivalents — parts that interchange. Searching by one reference surfaces vehicles covered by the others.
Attaching compatibility
- Open the product's compatibility tab.
- Search by vehicle or by reference number.
- Review the matched vehicles and remove anything that does not apply to your variant.
- Save — fitment lives on the product, so every channel listing built on it inherits the same list.
Over-matching is the risk, not under-matching. Engine size, body style and build date ranges are where equivalents pull in vehicles that do not actually fit. Sample-check before publishing a batch: a wrong fitment costs a return and a defect.
Exporting to eBay Motors
Stored fitment publishes in eBay Motors' compatibility format for the UK and US sites. Updating compatibility republishes it — the list is maintained once, not per listing.
