MaxiCode Generator
Generate a MaxiCode, the fixed size hexagonal symbol with a bullseye that parcel carriers use for high speed sorting. Enter up to 93 letters or 138 digits of printable ASCII text and the tool selects the encoding mode, adds the error correction and draws the symbol as a PNG image or an SVG file. It suits logistics developers who need test labels and sample artwork.
Frequently asked questions
What can I encode in a MaxiCode?
Printable ASCII text and line breaks, up to 93 letters or 138 digits in one symbol. Accented letters and other characters are refused, and text beyond the capacity of the symbol is rejected with a message.
Why does every MaxiCode have the same size?
MaxiCode has a fixed layout of 884 hexagonal modules around a central bullseye, about 28 by 26 millimeters at its nominal size. More data does not make it larger, which lets sorting scanners find it at speed on moving parcels.
Which mode does the tool use?
The tool selects the mode automatically. Plain text is encoded as general data in standard error correction mode. The structured carrier message of modes 2 and 3, with postal code, country and service class, needs control characters that this text form cannot carry.
Can I make a UPS shipping label with it?
Carrier labels require the exact message format and data agreed with the carrier, including control characters, so use the carrier's label software for live shipments. This tool is useful for test symbols, artwork and learning how MaxiCode works.
Can I download the MaxiCode as a vector file?
Yes. Choose SVG for a vector file that stays sharp at any size in print and design software, or PNG for a raster image that works in documents, web pages and label printers. Both come with a white background and a white margin.
What does the scale do?
The scale from 1 to 10, default 3, multiplies the size of the whole symbol. At scale 3 the symbol is about 330 by 300 pixels before the white margin.
How robust is MaxiCode?
MaxiCode uses Reed Solomon error correction on its primary and secondary messages, so a partly damaged or wrinkled label can still be read. The primary message is protected more strongly than the rest.
Can phones read MaxiCode?
Few phone apps read MaxiCode, because it is designed for industrial sorting scanners. Use a dedicated scanner or a decoding library to check the symbol.
Why are there no bar height or text options?
MaxiCode has a fixed geometry and no human readable line, so only the format and the scale can be chosen.
Is my data stored?
No. It is used only to draw the symbol you download.
