Most products in the U.S. use a 12-digit UPC barcode. Each section tells you something different.

1. First digit — Number system / country code
• The first number identifies the number system used.
• In many cases, it reflects where the barcode was registered, not where the product was made.
• Example: Numbers starting with 0 or 1 are commonly registered in the United States.

2. Next five digits — Manufacturer code
• These numbers identify the company that registered the product.
• Larger companies usually get shorter manufacturer codes so they can list more products.

3. Next five digits — Product code
• This part identifies the specific item made by that manufacturer.
• Different sizes, flavors, or versions of the same product get different product codes.

4. Last digit — Check digit
• This number is used to verify accuracy.
• It is calculated from the other digits using a formula.
• If the barcode is scanned incorrectly, the check digit tells the system something is wrong.

Important thing most people misunderstand

The barcode does not tell you where the product was manufactured.

A product can:
• Have a U.S. barcode
• Be registered by a U.S. company
• Still be manufactured overseas

The barcode identifies who registered the product, not where it was made.
