The right barcode for the job

CODE128 encodes any text compactly — the workhorse for shipping labels, tickets and internal tracking. EAN-13 is the retail standard worldwide (and UPC-A in North America): enter your 12 (or 11) digits and the mathematically-required check digit is computed and appended automatically — enter all 13 and it's verified instead, catching typos before they reach the printer. CODE39 survives rough printing and cheap scanners, which is why warehouses still love it. Every barcode renders crisp on canvas and downloads as a print-ready PNG.

FAQ

What's a check digit and why is it added?
EAN and UPC codes end with a digit computed from all the others — scanners use it to catch misreads. Enter 12 digits (EAN) or 11 (UPC) and it's calculated for you; enter the full code and it's verified, flagging typos instantly.
Can I sell products with a barcode made here?
The barcode itself is standard and scans anywhere — but retail EAN/UPC numbers must be assigned to your company by GS1. Use your assigned numbers here to generate the artwork.
Which type should I use for internal labels?
CODE128 — it encodes letters and numbers compactly and every modern scanner reads it. Use CODE39 only if your hardware specifically requires it.
