If you have a choice of format, try Code128 or Code39 if you need a 1-dimensional barcodes that can contain letters.

As the error message says EAN13 barcodes can only contain decimal digits, the standard doesn't specify any mechanism for encoding non-digits symbols. If you want to encode letters, you need to use a different barcode format. If you have a choice of format, try Code128 or Code39 if you need a 1-dimensional barcodes that can contain letters.
