catalog numbers
Product reference digits
Catalog numbers are alphanumeric codes assigned to items in a collection, inventory, or publication system to enable precise identification and retrieval.
Libraries use them to organize books, museums to track artifacts, and record labels to identify specific album pressings.
The rare first pressing has a different catalog number than the reissue.
For collectors, catalog numbers help distinguish between editions, variants, and releases that might otherwise appear identical.
