Location Software, Address Management & Postcode Address Software

The UK has the world's best postal code system. Every postcode (with very rare exceptions) is associated with a single street. Because of this accuracy postcodes have exploded out of their original role and are used in many fields such as administration, marketing and statistics.

Further, because of its short length and mnemonic form – "CB" is the prefix for the Cambridge area for instance – it's easy to remember.

Arc en Ciel Ltd uses the official Royal Mail data and other leading data sets to produce a range of Address Management Software, Location Software & Postcode Address Software.
