How to Find Auto Body Parts by OEM Number

A practical guide for parts buyers: where OEM numbers live on the part, how the number families work on NS and TY body parts, and how to turn a number off an old bumper into a line on a purchase order.

Where the Number Lives

Almost every plastic body part carries its original part number moulded or stamped on the back face: bumpers near the mounting tabs, lamps on the housing, wheel brows and boards on the inner clips. Clean the face with a rag — on a ten-year-old part the number is usually still there under the road film.

On NS parts you will see formats like 93829-BR01A; on TY, formats like 52119-0DC20. The first digit group identifies the component family — NS 62xxx numbers are front bumper and grille area parts, 26xxx are lamps, 63xxx front fender area. The suffix group encodes the vehicle generation and variant, which is why the same wheel brow exists as 93829-BR01A on the Qashqai 2010 and 93829-4EA0A on the Qashqai 2014.

Left, Right and Set Numbers

Handed parts carry two numbers: L (left hand) and R (right hand), always listed separately in this catalog — for example wheel brow RR, L:93829-BR01A / R:93828-BR01A. Left and right are defined from the driver's seat, not from the observer standing in front of the car. Ordering by the number pair avoids the single most common wholesale mistake: mirrored stock.

Some items are supplied as sets — grille sets, mud guard sets, radiator support sets. Set SKUs bundle the pieces that the vehicle maker sells separately, which is usually cheaper and always faster than assembling the set from individual lines.

From OEM Number to Aftermarket SKU

Aftermarket factories publish their own catalog numbers mapped to the OEM reference. In the SLCHN catalog the mapping is one line per part: SL number, part name, OEM number or numbers, and the vehicle application.

Paste the number from the old part into the cross reference search and the matching SL number appears instantly. When a number returns no match, it usually means a newer facelift variant or a market-specific version. Send the number with a photo of the part — variants often share the mould with a listed number, and genuinely new numbers feed the mould development plan.
