Can I find out which constituencies or Scottish Parliament region a postcode is in?
We have a Maps 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 using a webmap. 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, or through their website at

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.
