How an address is written in Iran

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

[Recipient name]
[State]
[City], [Neighbourhood]
[Street address]

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