1. OE / OEM Part Numbers (Original Equipment)
Assigned by vehicle manufacturers (e.g., Toyota 04465-33470, VW 5Q0 698 151). OE numbers provide the most precise fitment match for specific chassis, engine, and trim packages.

How to Identify Brake Pad Part Numbers: Decoding OE, WVA, FMSI, and AK Numbers
Navigating automotive aftermarket part numbers can be challenging when cross-referencing European, North American, and Asian catalogs. This comprehensive guide explains the key international numbering systems used in the global brake pad trade.
Quick engineering reference
WVA System5-digit European geometric standard
FMSI SystemNorth American D-number standard
Asian ReferencesOE / MK Kashiyama / Akebono
Database Size2,000+ cross-matched references
2. WVA Numbers (European Aftermarket Standard)
Created by the German Friction Materials Association, WVA numbers (e.g., WVA 23745, WVA 21647) define the exact physical dimensions, thickness, and caliper geometry of the pad regardless of vehicle brand.
3. FMSI D-Numbers (North American Standard)
The Friction Materials Standards Institute standard uses a 'D' prefix followed by a sequential number (e.g., D1080, D1377, D784) widely used by distributors across the United States, Canada, and Mexico.
4. Asian Aftermarket Cross-References (MK & Akebono)
Japanese and Asian aftermarket suppliers frequently reference MK Kashiyama (e.g., D2234) or Akebono (e.g., AN-650WK) catalog codes to identify shared brake pad shapes across Asian vehicle platforms.
