The database can be used with geocoding software to quickly add grid references to other postcode databases. Also, the full postcodes can be mapped as symbols at their approximate locations.
Postcode Sector Delivery Points Weighted Centroids contains the names and delivery points weighted centroids of all postcode sectors in the United Kingdom (over 9,000). You can add additional data fields to create your own postcode sector database. This data can also be used to geocode your existing postcode referenced database to the postcode sector centroid.
