How to get address from UK Postcode?

Question

I have a database, it has table customers one of columns is UK Postcode. Is it possible to restore full address using postcode ? I'd like to do it programmatically (c# or other)

Answer 1

Small user postcodes: collections of (usually) adjacent addresses. A single small user postcode may contain up to 100 addresses, but 15 is a more typical number

Since a post code represents a group of upto 100 addresses, you can't reverse engineer one to a specific address.
