Additional information

Solution (completely written out, just copy and paste!)

Replace zip countrycode NL with:

 <zip countryCode="GR"> <codes> <code id="pattern_1" active="true" example="12345">^[0-9]{5}$</code> </codes> </zip> 

in /app/code/Magento/Directory/etc/zip_codes.xml

Release note

I'm 41 years old and I have never seen anyone write a zip code with a space in between here in Greece.
So getting an error/warning during ZIP Code input is definitely frustrating!
I have seen that several other countries face the same problem with this validation. For Greece I can ensure you that everybody writes the Zip code like this 12345 and not 123 45.
Even if you check the wikipedia you will see that actually there is a categorization defined by the first 2 digits and not 3, so in any case the current implementation is wrong. As far as I know everybody writes all 5 digits together. You can check this also here which gives a list with all zip codes and they give them as continues 5 digit numbers.

I would like also to reference this issue which is similar and with the same solution.
