ACES (Aftermarket Catalog Exchange Standard) is the North American industry standard for the management and exchange of automotive catalog applications data. With ACES, suppliers can publish automotive data using standardized vehicle attributes, parts classifications and qualifier statements. ACES also prescribes a machine-readable format (XML) for trading partners to use in exchanging vast amounts of catalog information electronically.

The use of the ACES standard reduces number of formats needed to communicate product information removing duplicative efforts to communicate and distribute data in various formats. More efficient product communication gets products to market faster.

While the ACES standard is free, ACES utilizes Auto Care’s databases, some of which require a paid subscription . In using ACES, there are clear advantages to database (VCdb, PCdb, Qdb and Brand table) subscriptions. However maintaining your own data in-house may require more internal resources than you are able to commit. If you have your application data in an electronic format, there are many  service providers that will help map your data to the ACES format. Some service providers can send ACES files for you.
