Frequently asked questions
Which barcode type should I pick?
EAN-13 for global retail products, UPC-A for US retail, EAN-8 for very small packaging, Code 128 for any general-purpose label with letters and numbers, and Code 39 for industrial asset tags. If unsure, Code 128 is the safest general-purpose pick.
Do I have to calculate the check digit?
No. For EAN-13, EAN-8, and UPC-A you can type the number without the final check digit and it will be added automatically. If you do include it, it must be correct.
What characters can I use in Code 128 and Code 39?
Code 128 accepts any printable ASCII character up to 80 characters. Code 39 is more restrictive: uppercase A-Z, digits 0-9, and the symbols -. $/+% with a space, up to 80 characters.
What format and resolution do I get?
A high-resolution PNG with a white background, sized by the bar width and height you pick. Crisp enough for print or screen, scannable by any standard barcode reader.
How long is my barcode kept?
Generated barcode files are auto-deleted after 7 days. The barcode itself works forever once saved or printed.
