Frequently Asked Questions - Postcodes
These Frequently Asked Questions provide information about us and our work. If you cannot find the answer you are looking for in the sections above, contact us using the details at the bottom left of each page.
Can I find out which constituencies or Scottish Parliament region a postcode is in?
We have a Your Area section on this website which allows you to find out what UK Parliament constituency, Scottish Parliament constituency or Scottish Parliament region corresponds to a postcode, and download maps of those areas. Alternatively, both Parliament websites have a facility to look up the constituency for a postcode - follow these links for the Scottish Parliament or the UK Parliament.
How can I find out all the postcodes that are in a constituency?
The National Records of Scotland (formerly the General Register Office for Scotland) creates and maintains products which tabulate postcodes against other geographic areas, including constituencies. You can contact them to ask about obtaining these products by email at email@example.com, or through their website at http://www.gro-scotland.gov.uk/geography-enquiries.html. The Your Area section on this website allows you to find out constituencies for a postcode, but not to create a list of all postcodes for a constituency.
What does the Your area search do when a postcode crosses a constituency boundary?
Where a postcode crosses a constituency boundary, the Your Area search will return the constituency that contains the central point (mathematically, the centroid) of the area covered by the postcode. Where a postcode crosses a local authority boundary, the search will return more than one set of maps.
Do constituencies contain whole postcodes?
Not always. Postcodes are designed by Royal Mail for the delivery of mail. As a result, their boundaries are not generally suitable as constituency boundaries, and are ill-defined in areas with sparse postal delivery points. Postcodes are not a factor which we take into account when making recommendations for boundaries.
