FAQ - Barcode data is too long for this barcode type on Dymo LabelWriter
19 CommentsFriday, 10 June 2016 | Tech Support
Q) When I try to add an EAN13 barcode to my label it will only let me type in 12 numbers, if I type in 13 it says, "Barcode data is too long for this barcode type" - what is the problem?
A) EAN-13 barcodes are made up of 12 digits plus a single digit checksum, which the Dymo software calculates automatically. If you are using pre-generated barcodes that already include the checksum, then simply leave out the last digit. The Dymo Label Software will then add it back on.
