Choose a type and enter the data; the image appears at once. For EAN and UPC you can leave off the final check digit and it is calculated; if you include one it is verified. Barcodes cannot hold Thai text; use a QR code for that.

FAQ

What is a check digit?

The last digit of an EAN or UPC, calculated from the others to catch typing and scanning mistakes. If you leave it out we calculate it; if you include a wrong one we tell you what it should be.

Can I use these barcodes on products I sell?

The barcode itself follows the standard, but a real EAN or UPC number must be licensed through GS1 (GS1 Thailand in Thailand), not made up, or it may clash with another product.

Why will my barcode not scan?

Check that the quiet zone is wide enough (at least 10 bars), the bars are much darker than the background, and it is not printed too small. A standard EAN-13 is about 37 mm wide.
