Whilst looking around, you can tell us about the postcode of where you are looking. We want to collect information about where postcodes are now by finding them on old maps.
All you need to do is click on the the point in the map and fill in the postcode. Why not add your house, your place of work, and those of your friends and family, to help us build a free postcode database? There is more detail about why we want to do this in the FAQ.
