How an address is written in Kazakhstan

This is the order Kazakhstan's postal service expects. Square brackets mark what you replace.

[Postal code (040900)]
[State]
[City]
[Street address]
[Recipient name]
KAZAKHSTAN

Note the order: the postal code comes first, before the region and street — the reverse of the Western convention.

A postal code is optional in Kazakhstan addresses — mail is deliverable without one, though including it speeds up sorting.
