8896443230521

8896443230521 is a 13-digit numeric identifier used in the global trade item numbering system. It conforms to the EAN-13 barcode standard, which is employed to uniquely identify a single trade item in retail and logistics. The digits are composed of a GS1 prefix, a company prefix, an item reference, and a final check digit. The exact mapping of digits to a specific company and product is determined by GS1 allocations and the issuer’s catalog; the number alone does not reveal the product.

The final digit, 1 in this code, is the check digit used to verify the integrity of the full 13-digit sequence. To validate the code, calculate the check digit from the first 12 digits: sum the digits in odd positions (from the left) and add three times the sum of digits in even positions; take the result modulo 10. The check digit is then (10 − (sum mod 10)) mod 10. If this computed value matches the 13th digit, the code is structurally valid; otherwise, it may be incorrectly transcribed or invalid.

In practice, scanners read the code and query a product database maintained by GS1 or by the retailer to retrieve item data such as the product name, brand, price, and stock levels. Because 13-digit EANs can apply to a broad range of product categories, the same numeric pattern can represent different items across regions and suppliers, but each issuer’s code should map to a unique item within its catalog.

Note that ISBN-13 numbers used for books are also based on the EAN-13 format, but they typically start with 978 or 979 prefixes; this code does not. Without access to GS1 or retailer databases, the specific product associated with 8896443230521 cannot be determined from the number alone.
