| Letter Code | Usage |
|---|---|
A | Used for courtesy reply mail and metered reply mail with a pre-printed PostNet symbol. |
B | Used for business reply mail without a pre-printed zip code. |
C | Used for business reply mail with a pre-printed zip code. |
D | Used for Information Based Indicia (IBI) postage. |
Flattermarken
Used for the recognition of page sequences in print-shops, the Flattermarken is not a true barcode symbol and requires precise knowledge of the position of the mark on the page. The Flattermarken system can encode any length numeric data and does not include a check digit.
DAFT Code
This is a method for creating 4-state codes where the data encoding is provided by an external program. Input data should consist of the letters D, A, F, and T, where these refer to descender, ascender, full (ascender and descender) or tracker (neither ascender nor descender) respectively.
Note
Any characters other than D, A, F, or T are ignored.
