W1p: USPS 4-State Customer Barcode
Valid Characters: 0-9
Length: 20, 25, 29 or 31 digits
Valid bar widths: The width and height multiplier values of 00 will produce a valid USPS 4CB
symbol.
Usage: The bar code height field is ignored since the symbol height is United States Postal Service
specific. This bar code represents a 20 digit tracking code and a zero, five, nine, or eleven digit
routing code on a letter or package for the USPS.
The following example prints a USPS 4CB bar code:

Valid Characters: 0-9
Length: 18 digits
Valid bar widths: The fourth character of record is the width of the narrow bar in dots. All other bars
are a ratio of the narrow bar (2 times, 3 times, or 4 times the narrow bar width). Human readable
characters for this bar code symbology are printed above the symbol.
This bar code produces the same symbology as bar code ID "R", except that the human readable field
has been modified to print on the bottom of the bar code (see below).
