Which barcode format should I use?

CODE128 works for most general text and numbers. Use EAN-13 or UPC-A for retail products, and ITF-14 for shipping cartons.

Why does my value show an error?

Formats like EAN-13 and UPC require an exact number of digits. Check the hint under the value field for the format's requirements.

Can I print the barcode?

Yes. Prefer SVG so bars remain sharp, preserve the empty quiet zone, avoid resizing non-proportionally, and test a printed sample with the scanners used in production.

Does generating a retail barcode register a product number?

No. The tool only draws the value you provide. Official GTIN, EAN or UPC allocation and product registration must come from the appropriate standards organization.

SVG is preferred for labels and print because it scales without blur. Dark bars on a plain light background scan most reliably.
