Incorrect postcode data
We sometimes receive Zendesk tickets about postcodes not returning the right results. You can check the accuracy of the postcode by:
- Looking up the postcode on Mapit, for example https://mapit.mysociety.org/postcode/E18QS and viewing the parents. There can be more than one parent which can be the case if the postcode sits between two boundaries
- Get the latitude/longitude and look it up on Google Maps
If the data is incorrect you can contact ONS Geography firstname.lastname@example.org and ask them to correct the data for the next postcode release.
