In The Netherlands we have PostNL, the postal company. They use KixCodes, it's a fast way to deliver letters and packages that can be scanned during the process.

The code is a combination of:
Postal code, House/box/call number and House appendage / suffix
If there is a character between the house number and the suffix, we need to replace that with an X. Eventually, the code will be printed in the KixCode font.
