This page will let you view a single map of several postcode areas. Enter the areas you are interested in, separated by commas, and press the relevant button to see the postcodes. You can only view postcode areas down to the sector level (e.g. BB3 3)
Note: this page can also be used with Local Authority districts and wards and Lower Super Output Areas if you have the relevant codes for these areas (e.g. E06000002)
