Filled Map not showing ZIP code regions, but works with Points On Map

Question & Answer

I’m trying to create a Filled Map using ZIP codes, but the map doesn’t show any filled regions when I set “ZipCode” as the location field.

Here is a sample of the data I’m using:

Country,City,State,ZipCode,Population
US,New York,NY,10001,8419600
US,Los Angeles,CA,90001,3980400
US,Chicago,IL,60601,2716000
US,San Antonio,TX,78201,1547200
US,San Diego,CA,92101,1424400
US,Dallas,TX,75201,1341000

I set ZipCode as a geospatial field (Postcode) and tried using it as the location for the Filled Map, but no areas are being filled.

Interestingly:

  • When I use a Point on Map visual, the ZIP code locations are correctly plotted and the population totals are displayed.
  • When I use a Filled Map and set the location field to State orCountry, the map renders correctly and fills each state area with color.

Is there any way to make Filled Maps work with ZIP codes?
Or is this a known limitation in QuickSight?

Any advice or workaround would be appreciated!

Hi @jonosuke and welcome to the QuickSight community!
I just tested this out with a zip code field and the filled map was able to populate based on the zip codes. I’d be interested to see what field type you have your ZIP set as; in my dataset that was working, I had them setup as ‘postcode’:

Try switching to that if it’s not already and let us know if that fixes your issue!

Thanks for checking and sharing the info!

I just confirmed that my ZipCode field is already set to the postcode type.

As a test, I also tried adding ZipCode to the hierarchy for the Filled Map, but still, nothing was filled on the map.

Since you’re able to get it working with similar data, I’m starting to think the issue might be related to my setup or environment.
For reference, I’m using the Asia Pacific (Japan) region in QuickSight — do you think that could be affecting the map rendering or ZIP code support?

Appreciate any further insights!

Hi @jonosuke,
I checked around AWS documentation to see if there were any limitations for regions regarding geospatial fields and I don’t believe the region you’re located in has an affect on this. Since this seemed to work for me when testing out, my feelings are that this may be some type of bug for you. I would suggest creating a support ticket to get additional help from the AWS support team.

Thanks so much for your help and suggestions!

Before creating a support ticket, I decided to try one more time — and to my surprise, the Filled Map worked correctly with ZIP codes this time.
I’m not sure what changed, but it may have been a temporary issue.

Originally, I started testing with US ZIP codes because Japanese postal codes weren’t working for me —
but now even Japanese postal codes are rendering correctly on the map.

Really appreciate your time and support!

Hi @jonosuke,
I’m glad this worked for you! I’ve seen a few other instances as well where users have had similar issues and then, without changing anything, tried again and it started working…must just be some odd bugs within the mapping visuals.
