Maxicode Bar Code

The Maxicode bar code is a fixed-size, matrix-style symbology. It is made up of offset rows of hexagonal modules arranged around a unique bulls-eye finder pattern.

The United Parcel Service (UPS) designed the symbology for package tracking applications.

Maxicode symbols encode two separate messages: a primary message and a secondary message. The primary message usually encodes a postal code, a three-digit country code and a three-digit class of service number. The secondary message usually encodes address data and any other required information.
