ACN — American Card Number ACN — American Card Number

Corrections and contact

Spotted something wrong? We'd love to fix it.

ACN gets better when collectors point out what it missed. To report a mistake or a missing card or set, open an issue on GitHub issues. Please include:

  • the ACN number, or the set and year,
  • what's wrong or missing, and
  • a source if you have one, such as a published checklist or a photo of the card.

Accepted fixes are added as notes on the card's record. ACN numbers never change, so anything already cited stays valid. GitHub issues is the place for all corrections and questions about the catalog. ACN doesn't take corrections by email.
