POSTNET Barcode

This Symbology is also known as USPS POSTNET Barcode, USPS POSTal Numeric Encoding Technique Barcode, Delivery Point Barcode (DPBC), Postnet 3 of 5

Overview
The POSTNET (POSTal Numeric Encoding Technique) barcode was developed by the US Postal Service to encode ZIP Code information on letter mail for rapid and reliable sorting by BCSs. The POSTNET barcode can represent a five-digit ZIP Code (32 bars), a nine-digit ZIP+4 code (52 bars), or an eleven-digit delivery point code (62 bars).
The Delivery Point Barcode (DPBC) is formed by adding 10 bars to an existing ZIP+4 barcode. The 10 bars represent two additional digits (normally the last two digits of the street address, post office box, rural route number, or highway contract route number).

The Delivery Point Barcode (DPBC) - USPS POSTNET
The POSTNET barcode is always printed in a format that begins and ends with a frame bar (full or tall bar). To ensure POSTNET accuracy during mail processing, a correction character a.k.a. Checksum (five bars) must be included immediately before the rightmost frame bar of all POSTNET barcodes.
