POSTNET (Postal Numeric Encoding Technique)

DATA: Numeric LENGTH: Fixed CHECK: Required

POSTNET (Postal Numeric Encoding Technique) and FIM (Facing Identification Mark) are both used by the USPS (United States Postal Service). POSTNET is used to bar code ZIP codes, ZIP+4 codes and DPBC (Delivery Point Bar Code).

The JIT series of software products can be used to add the necessary Correction Character (i.e. a modulus 10 check character) to POSTNET bar codes. For your convenience non-numeric characters in your ZIP codes are skipped; so you can encode 12345-6789 or 123456789.

When you print POSTNET bar codes there should ideally be 22 bars printed per inch, but between 20 and 24 bars per inch is acceptable.
