UPC Lookup: How to Find Any Product by UPC Code in 2026

A UPC lookup is the fastest way to identify any retail product. Whether you're scanning items at a garage sale, building an inventory system, or sourcing products for Amazon FBA — knowing how to look up a UPC code is an essential skill in 2026.

What is a UPC Code?

A UPC (Universal Product Code) is a 12-digit number printed on virtually every retail product sold in North America. It's the number beneath the barcode lines that you see on product packaging.

UPC Structure:

• Digits 1-6: Company prefix (identifies the manufacturer)
• Digits 7-11: Item reference (identifies the specific product)
• Digit 12: Check digit (validates the barcode)

• Company prefix: 012345
• Item reference: 67890
• Check digit: 1

UPC vs. EAN vs. GTIN — What's the Difference?

Key insight: A UPC is actually a subset of EAN. To convert UPC to EAN, simply add a leading zero: UPC 012345678901 = EAN 0012345678901.

EcomSource accepts all identifier types and returns cross-references to all others automatically.
