Map visual not showing 2 post codes in UK

[sivarajan21]

Hi Team,

Quick question, i have a map visual as below:

The highlighted post code data are not appearing in map and these post codes are valid and exist in UK.

But they appear in a table visual. 

Any guidance would be much appreciated.

Hi @sivarajan21 ,

Thank you for raising this issue regarding the UK postcodes not rendering correctly in the map visual.

I’ve attempted to reproduce the behavior in my environment, and I can confirm the observation. When only the postcode (e.g., N12 0AZ) is used as the location in the map visual, it does not always render correctly. However, after adding the Town field along with the postcode in the Location section of the visual, it worked as shown below:

As pointed out by @danextian  and @johnt75 , Power BI uses Bing Maps (or Azure Maps, depending on the visual) for geocoding. These services may occasionally struggle to resolve standalone postcodes, especially in cases where multiple regions might share similar patterns. Including additional geographic context such as town or country name significantly improves location accuracy.

For the most consistent and precise results--particularly with larger or more complex datasets--we recommend enriching your data with latitude and longitude coordinates wherever possible.

Please feel free to reach out if you need any further assistance with implementing this approach or refining your dataset.

I've had issues like this before. If you search for those postcodes on Bing maps it doesn't know anything about them, and will only show the map for the outcode ( e.g. N12 ). I don't know if there's a mechanism to contact Microsoft and get them to add the missing postcodes.

Hi @sivarajan21 

Power BI uses Bing Maps for geocoding, but it may not always recognize certain postal codes or place names accurately. For the most reliable and precise results, it's best to use latitude and longitude coordinates.

Hi @danextian ,

Thanks for your quick response!😊

Sure will ask the team if they have co-ordinates.

Thanks!
