Same numbers but different barcode...

It doesn't generate the same EAN string.

This is the working one
image

and this is the non-working
image

I used the font called IDAutomationUPCEANM and not just the demo.

What's wrong?

Best Answer

Based on the image that you have supplied using our font, the barcode is not encoded. If you choose to generate barcodes using a font, you must encode the data before applying the barcode font (IDAutomationUPCEAN font).

Unlike fonts such as Times New Roman or Arial, barcode fonts require special formatting so that the data, when the barcode font is applied, will be scannable. This is true of most barcode symbologies with the exception of Code 39 and a few others. Formatting the data can involve adding start and stop characters or a check digit to the data; manipulating the data so that it is interleaved to create a smaller barcode, or converted to alternate characters that the barcode font can understand.

There are many types of barcode tools that will format data for a barcode—some tools are more automated than others.

Here is an example of a font encoder/font tool:

We have over 30 different font encoders free to use with our fonts and you should be able to use one of the ones located at https://www.idautomation.com/font-encoders/ depending on which application you are using.

If you are using Word or Excel, our Barcode Macro is the most popular and easy to use:
