A validation box is shown alongside all postcode fields in Adapt. Once a postcode has been entered the user needs to tab off the field to enable it to be identified as a valid postcode. A red tick will then appear in the box. Every postcode entered is checked against a postcode radius database (which uses Ordnance Survey postcode data). Once validated, northing and easting values are stored in the address table allowing the user to perform a postcode radius search against this data from all searches that contain address fields.
