030102999566

030102999566 is a 12-digit numeric code that functions as a UPC-A barcode identifier used in retail. UPC-A codes are designed to uniquely identify products, enabling automated scanning at checkout and supporting inventory, pricing, and supplier communications.

The structure of a UPC-A code consists of four parts: the number system digit, the manufacturer code, the product code, and the check digit. For 030102999566, the number system digit is 0, the manufacturer code is 30102, the product code is 99956, and the final digit 6 is the check digit. The check digit is calculated from the first 11 digits using the UPC formula; applying the standard calculation yields a check digit of 6, confirming the code’s validity as a UPC-A number.

In practical use, the digits correspond to an entry in a broader GS1 database that maps the manufacturer and product to a specific item. The leading zero is typical for UPC-A codes issued in North America and elsewhere, indicating the standard number system. While the code itself identifies the product in retail systems, the exact product name, brand, and other details require querying the appropriate GS1 registries or retailer databases.

Limitations and notes include that a UPC-A number does not convey product attributes directly, and not all numbers correspond to currently active products. The same format, however, remains widely adopted for product identification across supply chains, packaging, and point-of-sale systems.
