GTIN vs barcode

Client

GTIN vs barcode: the GTIN is the numeric identifier; the barcode is the visual encoding (UPC-A, EAN-13, etc.). Validate digits here—generate barcode images with the barcode tool.

Workflow split

Step one: validate GTIN mod-10 here. Step two: generate UPC/EAN barcode PNG with the barcode generator using the same digits.

?

GTIN‑8, UPC‑A (GTIN‑12), EAN‑13, and logistic GTIN‑14 all end with the same ISO/IEC GS1 modulus‑10 weight‑3 algorithm used by the barcode generator when it pads shortened bodies with a check digit. Alternate lengths map to retailer packaging standards (coupon GTIN‑12, carton GTIN‑14, compact GTIN‑8).

Result

Passes modulus‑10 GS1 rule for GTIN-13 (13 digits).

Common use cases

  • Clarify spreadsheet columns for ops teams.
  • Validate GTIN before sending artwork to label printers.

Common mistakes to avoid

  • Scanning a barcode image into this text field

    Paste the decoded digit string from your scanner—this page validates numbers, not images.

FAQ

Is GTIN the same as barcode?

No—GTIN is the number; barcode is how scanners read it visually.
