Hi

ISO 3166-1 contains the country codes, ISO 3166-2 contains the country subdivision codes, which are actually states. We can get the state codes by prefixing the country-code to ISO 3166-2 like this ISO_3166-2:IN to get the specific country codes.

I've searched all over, but I couldnt find any City codes. Isnt there any ISO for City Codes ?

Thanks

Well...Im a web-developer and I want to keep a unique database of a country-state-city list, so I checked the UN site and found out that they use ISO country codes so I searched and found that states codes also exist, but why the missing city codes ?

Hi Anjanesh,

Welcome to the Cove.

I doubt if the city code would be available. ISO 3166 - 1

ISO 3166 - Part 1 talks about the Country codes, while Part 2 talks about Country subdivision code.

You have rightly pointed that ISO 3166:IN will give the details about different states in India like in your case, it would be Maharashtra. ISO 3166 does talk about country subdivision which mean "States" in India or "provinces" in China but doesnot talk about city.

Imagine if city names have to be under this standard, then ISO would require full time personnel to track changes esp in India for so many changes in city names.

Chennai, Kolkata, Mumbai, Udagamandalam, Bengalooru, Mysooru etc. :lol:

I guess I will reveal with this my American (US) mindset, but we have postal codes here that can get VERY narrowly defined. Our large cities have several postal codes each, and I think the British have something similar. Why not default to these, where they are available?

Added later: Here they are called Zip codes. The "Z" stands for zone.

Thanks for your reply.

True, there would be many changes over time, but the frequency for the whole world would be....say once in a month ?

Is there any ISO for Postal codes ?

Come on guy .... you seem to be wanting everything under the "ISO umbrella" ;)

A postal code is a series of letters and numbers added to a postal address to aid in the sorting of mail. Every country uses a different format for their postal codes and thus there is no ISO.

Refer this interesting wikipedia link for details. http://en.wikipedia.org/wiki/Postal_code

Btw, there is one organisation called as Universal Postal Union for the postal codes. Their website is http://www.upu.int/

:lol:
