About Code 11
Code 11 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.

Print at sufficient height so narrow bars do not blur on inkjet printers.

Verify check digits before mass printing EAN and ITF symbols.
