Royal Mail Cleanmail CBC Tool

Instructions

This tool takes a UK postcode (and optionally a DPS), and returns its checksum character and CBC barcode for use with Royal Mail's Cleanmail system.

1. Enter a postcode and DPS. If no DPS is entered, the default of 9Z is used.
2. Choose what type of output you require.
   • Normal: The output will be a web page with the postcode, DPS, checksum character and CBC barcode.
   • Checksum: The output will be a plain text checksum character corresponding to the postcode and DPS.
   • CBC Barcode: The output will be a GIF image of the CBC barcode.
   • CBC String: The output will be a plain text string of the raw data behind the CBC barcode.

You can also read the Cleanmail manual from Royal Mail.
