EAN-13 is the 13-digit barcode on almost every retail product outside North America.
The 13-digit retail barcode used worldwide
Check digit 1 — encoded as 4006381333931
Enter 12 digits and the 13th — the check digit — is calculated for you.
Enter the 12-digit number. The check digit appears beside the field as you type.
Check the number is one you're entitled to use — see the FAQ on GS1 prefixes.
Adjust the bar height and quiet zone for the packaging it's going on.
Download SVG so the bars stay crisp at whatever size it's printed.
Take the 12 digits, weight them alternately from the right — the rightmost by 3, the next by 1, and so on — add the results, then subtract the total from the next multiple of ten. This page does it as you type, which is also a quick way to verify a number you've been given.
Not for retail. The first digits are a company prefix issued by GS1, and a number you make up may already belong to someone else — which is how two different products end up scanning as the same item. This tool generates a technically valid barcode from whatever digits you enter; it can't allocate the number itself. For internal use where nothing is scanned at a till, Code 128 avoids the problem entirely.
UPC-A is the 12-digit North American form, and it's really an EAN-13 with a leading zero. Modern retail scanners read both. If you're selling in North America, use UPC-A; elsewhere, EAN-13.
The nominal size is about 37 × 26 mm. GS1 allows scaling between 80% and 200% of that, and going below 80% is where scan failures at the till start. If it won't fit, EAN-8 exists for exactly that reason.
