ONS places a whole postcode in one council, one ward and one constituency, from a single point. A few postcodes cross a boundary, so an address at the edge can belong to the one next door. Your council tax bill or your poll card settles it for your address.

A parliamentary constituency is an area that elects one MP to the House of Commons at Westminster. A postcode is placed in one constituency.
This is your Westminster constituency (ONS Postcode Directory, August 2026). Scottish and Welsh postcodes also show their Scottish Parliament or Senedd constituency.
Constituency boundaries are reviewed from time to time, so a postcode can move to a different constituency when they are redrawn.
Is my constituency the same as my council?
No. A constituency elects an MP to Parliament. A council runs local services, and a ward elects councillors to that council.
The two sets of boundaries are drawn separately. One council area can be split between several constituencies, and a constituency can take in parts of more than one council area.
