Frequently Asked Questions (FAQ)

What is the difference between CODE128 and EAN13?

CODE128 is a versatile format that can encode any combination of letters, numbers, and symbols. EAN-13 is strictly a 13-digit numeric barcode used globally for retail point-of-sale systems.

Why does my barcode show an error?

Different barcode types have strict rules. For example, an EAN-13 barcode requires exactly 12 or 13 numbers. If you type letters into an EAN-13 format, or if the number of digits is incorrect, the generator will show an error. Switch to CODE128 if you need to use letters.
