Preguntas frecuentes
Why do I get an invalid check digit error for EAN-13 or UPC?
Retail formats such as EAN-13, EAN-8, UPC and ITF-14 have fixed lengths and a check digit. When the value has the wrong length or its check digit does not match, the tool reports that the value or check digit is invalid for that format.
Which barcode format should I use for letters and numbers?
CODE128 is the default and encodes letters, digits and symbols, and CODE39 also accepts letters. EAN-13, EAN-8, UPC and ITF-14 are numeric formats used for retail products and shipping cartons.
Can I download the barcode as a vector file?
Yes. The barcode is built as an SVG with a 20-pixel margin and saved as barcode.svg, which scales cleanly for print layouts. Turn off Display value below barcode if you want the bars without the text line.
Where is my input processed?

What are the input limits?
