What is TecDoc Catalogue?

TecDoc Catalogue is TecAlliance’s professional automotive parts catalogue for the independent aftermarket. It connects vehicle data, article data, OE references, IAM part numbers, product groups, manufacturer data, technical details, and vehicle applications into one structured parts identification system.

Instead of relying on incomplete parts lists or manual cross-checking, TecDoc allows users to search by vehicle, VIN, OE number, article number, product group, barcode, or catalogue data to find compatible replacement parts with higher accuracy and fewer ordering errors.

VIN Lookup, OE Numbers & Cross-Reference Search

TecDoc is especially valuable for parts identification because it supports multiple search paths. Users can identify vehicles through VIN filter or vehicle selection, then locate parts by product category, OE reference, IAM number, article number, barcode, or vehicle application.

TecAlliance specifically highlights OE-to-aftermarket cross-referencing as a way to match original equipment references with aftermarket equivalents, reducing misorders and helping users source the correct replacement parts faster.

Vehicle Linkages & Article Data

The strength of TecDoc is its structured link between vehicles, products, article data, and manufacturers. TecAlliance’s online shop lists more than 450 million vehicle linkages, more than 190,000 TecDoc vehicle types, and more than 9.8 million article data records, making the platform one of the most comprehensive parts-identification systems in the automotive aftermarket.
