Postalcode for multiple countries

Question

Having a column that mixes German (5 digits) and Austrian (4 digits) postal codes. How can I make Tableau understand both correctly?

The column reads something like

postal-code
53173
99848
1080
1030

I assigned a geo-role to a second column that distinguishes the countries:

country-code
DE
DE
AT
AT

Answer 1

I used the data that you provided and I had no issue with Tableau recognizing them correctly.

You may need to specifically set the Geographic role for each field, but that should be it.
