What is a POSTNET Barcode?
A POSTNET barcode assists the USPS in directing mail by encoding the ZIP or ZIP+4 code and the delivery point. POSTNET barcodes improve the speed, accuracy, and delivery of mail. There are three different types of POSTNET barcodes that can be printed: 5-digit POSTNET barcodes, which have a total of 32 bars; ZIP+4 POSTNET barcodes, which have a total of 52 bars; and Delivery Point Barcodes (DPBC), which have a total of 62 bars.
What is a POSTNET Barcode Generator?
As the name suggests, a POSTNET barcode generator is an application or program that generates POSTNET barcodes or POSTNET barcode data for mail and packages.
How Can I Use a POSTNET Barcode Generator?
To start generating data for POSTNET barcodes, sign up for a CASS™ Certified postal address verification service like CDYNE’s PAV API. Address verification services not only ensure that address data is correct and formatted properly before being used for barcode generation, but also provide additional POSTNET barcode data.
What Does Our PAV API Do?
Postal Address Verification (PAV) standardizes, corrects, and verifies addresses for deliverability before mail and packages are sent out. In addition to this, our API automatically generates data for a POSTNET barcode for each address, including ZIP+4 codes, two-digit delivery point codes, and delivery point check digits.

Barcode Digits and Bars
POSTNET barcodes start and end with a full bar and have a check digit after the ZIP code, ZIP+4 code, or delivery point. Each individual digit is represented by a set of five bars, two of which are always full bars. There are initial and terminal full bars at the beginning and end of the barcode.
In each set of five bars, a full bar represents an “on” bit and a half-height bar represents an “off” bit in a pseudo-binary code, encoded as 1 and 0 respectively. In this code, each of the five bar places represent 7, 4, 2, 1, and 0 from left to right, though 0 is technically encoded as 11 in decimal.
