Whose post code (почтовый индекс) I must type?

I’m not too familiar with Russia’s postal system, but I found this article on Wikipedia that may help: Postal codes in Russia - Wikipedia

EDIT: Also see this: Postal codes in Russia - Wikipedia

But I know post code in Russia.
I do not know whose code I must type.
Shall I type my post code
or I must type else post code?

Your own postcode :slight_smile:

Check for your postal code on Georgia, United States Zip Codes and try again. Basically, there should be no mistakes because of it. If you won’t be able to update it again then ask for the help by a support service.
