Sample MaxiCode Packets
MaxiCode is a two-dimensional bar code developed by UPS (United Parcel Service, Inc.). Data
must be defined in a specific way for UPS. Refer to the Guide to Bar Coding with UPS or the
AIM MaxiCode Specification for more details about data requirements.
The printer supports modes 0, 1, 2, and 3. Contact us for information about additional
MaxiCode modes.
Mode Description

1 Osbolete
2 Structured Message
3 Structured Message
You can select which mode to use in the bar code field or allow the printer to auto-select the
mode (0, 2, or 3) based on your data. See “Defining a Bar Code Field
” for more information.
MaxiCode automatically pads data with the “!” character.
Note: MaxiCode does not support the NULL character.
Modes 2 and 3 are defined by the way the postal code, class of service, and country code
fields are arranged. (The postal code, class of service, and country code are required fields.)
Begin with the message header, then the primary data (15 characters), followed by the
secondary message (up to 78 characters). Or, begin with the primary data, then the message
header, followed by the secondary data. If the postal code data characters are all numeric then
the MaxiCode symbol is set to Mode 2. If the characters are alphanumeric, or only contain
ASCII characters 65 to 90, then the MaxiCode symbol is set to Mode 3.
If you receive an error 612, check your MaxiCode data. You may have not correctly structured
or left out one of the three required fields (postal code, class of service, and country code) or
the “~029" character.
