Chapter 4 Postnet Barcodes

Parameters In POSTNET

When used with POSTNET barcodes, some parameters function differently than when used with other barcodes. These parameters are as follows:

^IBARC,POSTNET,B,98032^

The Below (B) parameter adds human-readable characters below the barcode, but unlike other barcodes, does not reduce the height of POSTNET codes.

^IBARC,POSTNET,E,98032^-

Normally, using the Embedded (E) parameter reduces the height of the barcode. However, because of POSTNET barcodes’ height requirements, characters that would normally be embedded are instead printed below the barcode, as if the B parameter were used.

^IBARC,POSTNET,N,98032-1122^-

Hyphens are ignored in POSTNET barcodes. Illegal characters (not digits or hyphens) are printed as zeros.

^IBARC,POSTNET,R1:4,N,98032^-

The required ratio for POSTNET barcodes is 1:4 (bar:gap), but may be modified using the Ratio (R) parameter. Ratios other than 1:4, however, do not meet the United States Postal Service specifications for POSTNET barcodes.

AIAG Barcodes

The AIAG barcode style is used by the automotive industru. It is actually a Code 39 style with no check digit and is encoded according to the AIAG specification.
