Where can I get postal codes for all countries?

Question

I once read about an open source database for postal codes with geolocation data but now I can\'t remember its name. Can someone help?

Answer 1

Yes Geonames is the place. To be more specific as slacy said

https://download.geonames.org/export/zip/

It has a list of countries' postal codes and it has an allCountries zip file.

And the data is updated daily.
