Calculate the final digit
Use 12 EAN data digits to construct a complete EAN-13 value.
Calculate an EAN-13 check digit, validate a supplied barcode value and send a valid result to the generator without retyping it.
Check a barcode value or build standards-aware GS1 data.
For EAN, UPC or GTIN, enter the complete value to verify it or omit the final digit to calculate it. Spaces and hyphens are ignored for those standards.

Required. Valid shorter GTINs are zero-padded to 14 digits; 13 GTIN-14 data digits receive a calculated check digit.
Parentheses identify Application Identifiers in the readable text; they are not encoded as data. Required FNC1 separators are inserted automatically.
Syntax and checks can confirm a well-formed value, not whether a GTIN was assigned to your organisation.
Enter a GTIN to build a GS1 code.
Processed locally. EAN values and check-digit calculations stay in this browser.
Enter 12 data digits to calculate the final digit, or enter all 13 to compare the supplied checksum. The validation result explains the expected and received digit before you choose a correction or generate the code.
Use 12 EAN data digits to construct a complete EAN-13 value.
A complete value reports the expected and received check digit.
Send the validated result to the shared generator, then use labels when needed.
No. It validates arithmetic structure only; product identity needs an authoritative source.
Yes. Send it to Create, Batch or Labels after reviewing the result.
