Thirteen digits with a wrong final digit
The weighted modulo-10 calculation does not match the supplied check digit.
Compare the first twelve digits to the source and calculate the expected final digit.
EAN-13 barcode generator
Generate and validate an EAN-13 barcode
EAN-13 encodes twelve data digits plus a final check digit. Enter twelve digits to calculate the thirteenth, or paste a complete value to verify it before producing SVG, PNG or PDF artwork with the required blank margins.

A practical workflow
How to use it
- 01
Enter 12 or 13 digits
Use data-only mode for twelve digits or verification mode for the full number.
- 02
Review the check digit
Resolve any mismatch in the source record rather than silently changing an assigned GTIN.
- 03
Export at a tested size
Keep quiet zones, avoid non-uniform scaling and scan a physical sample.
Avoid rework
Common errors and precise fixes
Confusing an internal number with GTIN-13
An arbitrary 13-digit number can satisfy the checksum without being assigned for retail use.
Confirm assignment separately; use Code 128 for unrestricted internal alphanumeric identifiers when appropriate.
Know the limits
BatchLabel does not issue GTIN-13 identifiers or verify company ownership.
A structurally valid value and clear preview do not replace a print-quality test.
Questions, answered
Before you continue
Can I enter only 12 digits?
Yes. BatchLabel calculates the EAN-13 check digit and shows the complete 13-digit value before generation.
Is EAN-13 the same as a UPC?
They belong to the GTIN family but have different common representations and data lengths. Use the format required by the receiving system rather than trimming or adding digits casually.
