About Codabar
Codabar is used for libraries, blood banks, and legacy inventory systems.
Related formats in this family include MSI Plessey, Codabar, and Code 11. Pick the symbology your scanner or retailer expects.
ForQRCode renders valid bar patterns for proofing and internal labels. Retail distribution may still require official GS1 identifiers where applicable.
Tips for Codabar labels
- 1
Leave quiet zones (margin) on both sides of linear barcodes.
- 2
Print at sufficient height so narrow bars do not blur on inkjet printers.
- 3
Verify check digits before mass printing EAN and ITF symbols.
- 4
Test scan with the same engine your warehouse or POS uses.
