Add Zipcodes/PostalCodes on the Cities(not states nor countries API endopoints),Optional recommendation to add provinces/countys at the same category

[zacky420]

this would be good to expand the API's capabilities, and extend even more this API, i can give you the Schema if needed, it should be like this:

zipcode string

This because there are some countries that instead of having the 5 number standard, has letters too like UK(as always😒), so putting it on only numbers would be a bad idea

You can add provinces in States, so you can fix the UK County problems, and others relate(Valencia has 3 provinces/countys, Valencia, Alicante & Castellón).

I agree, adding the zipcode to cities will be a good enhancement, please consider.

I think it could be useful, but there are a number of things to consider:

• Partial Postal Codes: As in the UK or Canada, where you'd likely only have the first three characters, since the last three characters are more "street level" precision
• Some cities would have multiple postal codes
• The postal services in some countries retain a copyright. See: https://opennorth.ca/resources/open-postal-code-data

At the same time, I'm wondering whether postal code would be better served by a sister database, which is optimised for that data?
