The Japanese postal barcode is used in mail sorting for Japan. It encodes an 7-digit postal/zip code plus an optional alphanumeric address code. The symbology allows the coding of the digits 0-9, letters A-Z, and hyphen. The address code is simply the alphanumeric portion of a street address.
This sort of bar code system is regarded as "four-state" because there are four types of bars, classified by presence of ascenders and/or descenders. This sort of system is transcribable using DAFT notation. These sorts of bar codes are used by a number of countries in their postal systems, though the specific symbologies by which they encode characters can vary.
[edit] The scheme
The start and end bars are FD and DF. Each character takes up three bars. Padding with TDA is performed to fill 20 chars.
