What is a zip code? This is a character set that is added to the mailing address when sending a letter. It is needed in order to sort mail faster and easier. In Russia, the postal code consists of six digits. The first three indicate the area code, the last the post office number. In large cities (such as Moscow) there may be several city codes.
Instruction manual

An incorrectly written index can lead to the fact that your letter does not reach the addressee right away - at first it will take a trip to that post office, the code of which you mistakenly indicated - and only after that it will be forwarded to its destination. Therefore, it is better to write zip codes without errors. But how do you know the code of the post office to which your addressee is "assigned"?

Firstly, you can find the index in any branch of the Russian Post. Just name the city and name (sometimes a house number may be required). Mail staff will check the directory containing data on the service area of all post offices in Russia and give you the required index.

If you are "friends" with search engines, then you don’t need to go to the post office. By the query "indexes of Russia" or "indexes of the city N", you can immediately find resources that allow you to find out what you are looking for. This information is not classified, and is freely available absolutely legally.

To find the index that interests you in the database, first select a city, then select a street. It happens that houses on the same street are served by different post offices. In this case, the site indicates by what principle they are divided. Choose the right one - and feel free to write the index on the envelope, you won’t be mistaken!
