Tesla Model 3 & Model Y aftermarket parts: catalogue data and OE coverage
Here are the numbers behind MapleV's Tesla parts catalogue, for estimators, journalists and anyone sizing up the aftermarket Tesla collision-parts market in Canada. The catalogue covers 287 Model 3 and Model Y collision and suspension parts, cross-referenced to 521 distinct Tesla OE part numbers across 355 base numbers in the published dataset (snapshot of 2026-08-29; the live OE lookup shows the numbers currently published).
Every primary OE number was checked against Tesla's official Canadian parts catalogue in August 2026. Of 282 eligible records: 49.6% returned the identical full OE string, a further 48.2% returned a different full number sharing the same seven-digit base, and six returned neither. The six are listed individually in our published audit file — two are carried by the catalogue under a different number we already cross-reference, two are pre-facelift Model 3 headlamps, one is a Highland Performance trim piece, and one is a seat switch whose number did not resolve. It's the kind of coverage that lets a body shop quote an aftermarket Tesla panel against a Mitchell or Audatex line without guessing at interchange.
The catalogue in numbers
287 parts across Tesla Model 3 (2017 onward, including the 2024 Highland refresh) and Model Y (2020 onward, including the 2025 Juniper refresh) — bumpers and fascias, fenders, hoods and front-end panels, headlamps and tail lamps, mirrors, grilles and cooling, underbody shields, wheel liners, brackets, and front and rear suspension.
521 distinct Tesla OE part numbers are cross-referenced across those 287 parts — because a single physical part is often sold by Tesla under several numbers as it is revised, and because differing build configurations (for example, with or without park-assist sensor holes) each carry their own number.

Why 116 parts carry multiple revision numbers
Tesla revises parts continuously, issuing a new revision letter (-A, -B, -C…) each time. In the MapleV catalogue, 116 part families carry two or more revision letters of the same base number — a single wheel liner spans -C, -D and -E; a rear aero shield spans -D through -F. Revision letters across the catalogue run all the way from A to L.
For a shop, the practical rule is: search on the 7-digit base number and treat the trailing letter as a version. Confirm the match against the vehicle and Tesla's EPC before ordering — a shared base is a search key, not proof of interchangeability. A fuller explanation is in our guide to reading Tesla part numbers.
Middle-code variants in the data
The catalogue also records the two characters that sit between the base and the trailing letter — we call them the middle code, for counting purposes only. Across the 521 globally deduplicated full OE numbers in the 2026-08-29 frozen snapshot: 428 use 00, 15 use S0, 12 use E0, 9 use SC and 9 use EC; eleven further codes account for the remaining 48. We report these observed values without assigning them Tesla-defined meanings — we have not been able to source a definition to Tesla documentation, so we do not guess at one.
A small number of entries also carry China-market numbers (a -CN- code). In our own catalogue checks these did not resolve in the North American catalogue we searched; we record that observation without asserting what the number denotes. So an estimator who meets a number like 1619812-CN-A that a North American lookup can't resolve can still find the part here.
Look any of it up
All of this data is searchable free, with no login, through the MapleV OE lookup tool — type any Tesla Model 3 or Model Y OE number, with or without dashes or by its 7-digit base, to identify the part and see every cross-reference number. The full browsable table is on the cross-reference page.
Frequently asked
How many Tesla parts does MapleV catalogue, and for which models?
287 collision and suspension parts for the Tesla Model 3 (2017 onward, including 2024 Highland) and Model Y (2020 onward, including 2025 Juniper), cross-referenced to 521 distinct Tesla OE part numbers.
How accurate are the OE numbers?
Of 282 eligible primary OE records: 49.6% returned the identical full string in Tesla's official Canadian parts catalogue, 48.2% returned a different full number under the same seven-digit base, and six returned neither. The six that did not resolve are listed individually in our published audit file at maplev.ca/data/tesla-oe-epc-audit-2026-08-26.json.
Why does one part have several OE numbers?
Tesla revises parts and issues a new revision letter each time (-A, -B, -C…), and differing build configurations each carry their own number. Search on the 7-digit base number and treat the trailing letter as a version, then confirm against the vehicle and Tesla's EPC before ordering.
