OEM vs aftermarket luggage part numbers: how to read the identifiers A part number is only as meaningful as its source and scope. An aftermarket or specialist code can be useful without becoming an OEM identifier.

Original provenance diagram: identifier systems and fit evidence are separate questions. How to read an identifier safely Ask who assigned the identifier: manufacturer, authorized service channel, specialist seller, or generic marketplace seller. Keep OEM part number and aftermarket part number as separate fields. Never relabel a specialist code as OEM. Check whether the source maps the identifier to a collection, exact model/style, size, side, revision or production window. Read the compatibility status. A precise-looking code can still be LIKELY or UNVERIFIED. Check explicit non-fit records for the same code before ordering. Accepted database examples VERIFIED OEM example: Briggs & Riley ACC-5196-4 The accepted compatibility data OEM field carries ACC-5196-4 with published @work/Baseline scopes.
What it proves: The manufacturer identifier and its stated scope.
What it does not prove: It does not make visually similar generic foot kits equivalent.
Open compatibility record → VERIFIED Aftermarket/specialist example: HW1075A accepted compatibility data stores HW1075A in the aftermarket field for DELSEY Helium Aero 19/21-inch spinner hardware based on specialist mapping.
What it proves: A source-backed specialist identifier and fit scope.
What it does not prove: It is not presented as an OEM DELSEY part number.
Open compatibility record → DOES_NOT_FIT Same aftermarket code, wrong size: HW1075A on 25/29-inch Helium Aero The negative record preserves a wrong-size/interface conflict.
What it proves: That the code must not be generalized across size groups.
What it does not prove: A known aftermarket code is not universal within a collection.
Open compatibility record → LIKELY Generic aftermarket B001 carry handle B001 is a measurement-led candidate with a dense geometry signature.
What it proves: The seller identifier and candidate geometry.
What it does not prove: No exact luggage model crosswalk is asserted; dimensions alone do not create VERIFIED fit.
Open compatibility record → Do not “upgrade” provenance: a specialist mapping can be excellent evidence and still remain an aftermarket/specialist identifier. The database keeps that distinction so users can judge the claim correctly.
