                | Description | The postcode sector is the first block (the postcode district) of a UK postcode plus the first number of the second block. For example with DN55 1PT it would match DN55 1. Its a loose match as it only ensures that the format is correct, it doesn't validate the letters and numbers. It doesn't let in the non-geographic codes postcodes SAN TA1 and GIR 0AA. It will pull out the first block & the sector code of any of the matching examples below. Examples of the names of the different parts of a UK postcode can be found here: http://en.wikipedia.org/wiki/Postcodes_in_the_United_Kingdom#Life-cycle_of_post_codes |
