Try out an AFD Postcode Search for yourself or if you already know the postcode, its faster to use Postcode Lookup

Enter details of UK address (letter box) to find the full Royal Mail address and postcode for it. If the address detail you supply returns more than one possible answer, we'll supply the first 50 matches we find. Many addresses can be located by just entering a street address like '51 Meadowfoot Road' or a name 'AFD Software'. More common addresses like '12 High Street' are best entered with a Town or County name.

If you are unsure which part of the address you have, check the wide search option box - and we'll look in all fields for your data, but this will be a bit slower.

If you are not certain of the spelling of an address element, place a '$' in front of the entry - like $51 Medofut Rode'
