About the Barcode Generator

Generates linear barcodes in the common retail and logistics symbologies. The format is dictated by the use rather than preference: EAN-13 and UPC-A for retail products, Code 128 for shipping and internal tracking, Code 39 where older hardware is involved.

Each symbology constrains its input — fixed digit counts, a required check digit, a restricted character set — so an input that is rejected is usually the wrong format for the data rather than a fault. Print at adequate size with clear quiet zones on both sides, or scanners will struggle regardless of correctness.

Frequently asked questions

Which barcode format should I use?

CODE128 for anything internal — it encodes the full ASCII set, is compact, and is what most warehouse and asset systems expect. EAN-13 and UPC-A are only for products sold at retail, and they require a registered GS1 company prefix; you cannot invent a valid one. ITF-14 is for shipping cartons.

Do I need to supply the check digit?

No. For EAN-13, EAN-8, UPC-A and ITF-14 you can enter one digit short and the check digit is calculated for you. If you supply the full length, it is validated — so a rejected value usually means a mistyped digit.

Can I use these barcodes commercially?

The images are yours to use freely. But a retail barcode also needs a legitimate GS1-assigned prefix to be scannable in shops — generating a valid-looking EAN-13 does not register that number to you. For internal inventory, CODE128 needs no registration at all.
