All Postcodes in the SY18 Postcode District

Below are all of the active postcodes that we currently have on file for the SY18 postcode district. The list also includes expired postcodes that we may have data for (those that have been discontinued by Royal Mail). We maintain several years of data on expired codes. Click here to view demographic information about SY18 as a whole.

Note: Some postcodes may be listed as "Large User" - this indicates that they are assigned to large businesses and similar entities, rather than residential homes. While we often have data on the areas in which these postcodes exist, some are not tied to a particular place, so data on these may be more limited.
