Maxi Code is an international 2D (two-dimensional) barcode that is currently used by the UPS (United Parcel Service) on packing slips for world-wide addressing and package sortation. MaxiCode barcode symbols are fixed in size and are made up of offset rows of hexagonal modules arranged around a unique finder pattern. The size of a Maxicode barcode symbol is 1.11 x 1.054 inches and allows up to 93 data characters of information. MaxiCode barcodes include error correction, so the symbol can still be decoded when it is damaged.
The MaxiCode barcode encodes two messages; a primary message and a secondary message. The primary message usually encodes the postal code, country code and the class of service number. The secondary message usually encodes address data, but can encode other types of information as well.
MaxiCode barcodes have different modes of operation. MaxiCode supports the following modes:
•2 - US Carrier with postal codes up to 9 digits in length.
•3 - International Carrier with alpha-numeric postal codes up to 6 digits in length.
•4 - Standard Symbol - use this option to encode information for purposes other than the shipping industry. Up to about 90 characters can be encoded in this mode.
•5 - Secure Symbol - use this option to encode information with more error correction. Up to about 74 characters can be encoded in this mode.
•6 - Reader Program - this option allows scanner manufacturers to program their barcode readers.
