Dear Jorge,

I am not sure whether this helps, because I do not have your data, but here's an idea. Suppose we look at US zip codes in the range from 85001 to 85055. We can generate the Entities for these codes:

zipcodes = Cases[Interpreter["ZIPCode"][ToString /@ Range[85001, 85055]], _Entity]

Let's generate a list of fake numbers of people who did the test:

teststaken = RandomInteger[{1, 500}, Length[zipcodes]]

Then this should work:

GeoRegionValuePlot[Rule @@@ Transpose[{zipcodes, teststaken}]]

Hope this goes in the right direction.

Cheers,

Marco

I have a dataset of over a 1000 zipcodes so it takes a lot of time. I'm getting this weird message:

It's really strange, for three reasons at least:

1. The first, I've never sene a "Try again" message. What does that mean?
2. The second reason is that 06883 is a valid zipcode that for example, Wolfram Alpha recognizes.
3. The line I'm running is something like zips = Interpreter["ZIPCode"] /@ {"95014", "01545", "94087", "95129", "01810", "10471", "02067", "01720"...} It does not always interpret the same ZIP codes the right way. For example, the first time I ran it, there was no issue with code 94568, but the second time it showed the aforementioned error.

What could be the issue? I'd appreciate any suggestions.
