TCID is an open registry standard that assigns a stable, opaque alphanumeric identifier to every distinct trading card type — enabling platforms, insurers, grading companies, and collectors to speak the same language.
Every platform in the trading card market — grading companies, marketplaces, insurance carriers, collector apps — uses a different internal identifier for the same card. There is no shared canonical key. TCID solves this by assigning a stable, permanent, non-proprietary identifier to each distinct card type, governed by a neutral nonprofit standards body.
A TCID, once assigned, never changes. Cards do not get re-numbered when manufacturers release new checklists or platforms update their databases.
Identifiers carry no embedded meaning. Modeled on CUSIP and ISIN, an opaque identifier survives manufacturer rebranding, sport expansion, and schema changes.
The TCID identifier itself is published under Creative Commons Attribution 4.0. Any platform, tool, or collector can reference a TCID at no cost.
TCID is owned and maintained by a nonprofit standards body — not by any manufacturer, marketplace, or grading company — ensuring no single commercial interest controls the standard.
TCID occupies the foundational type layer. Higher layers reference TCID — they do not replace it.
Card fingerprinting / optical signatures (e.g., Genamint-style). Identifies a specific physical card — useful for tracking ownership of a single graded slab.

PSA Cert #12345678 (references TCID below)The foundational identifier for the card type itself: player, set, year, parallel, and variation. Analogous to a VIN model code — every copy of this card shares the same TCID.

TCID is operated under a two-entity structure: a nonprofit standards body that owns and governs the identifier, and a commercial registry services company that operates the API and data products. This separation ensures the standard cannot be captured by any commercial interest.
Delaware 501(c)(6) trade association. Owns the TCID standard. Sets identifier policy, data schemas, and governance rules. Board includes independent industry representatives. No manufacturer voting rights.
Delaware C-Corp. Operates the registry database, API layer, and data products under license from the Standards Organization. Revenue funds nonprofit governance operations plus commercial operations.
The TCID Registry API provides structured, authenticated access to card type data. The identifier itself is always free. API membership unlocks enriched metadata, batch lookup, and commercial use rights.
