How an address is written in Argentina

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

[Recipient name]
[Street address]
[Postal code (C1070AAM)] [City]
[State]
ARGENTINA

A postal code is optional in Argentina addresses — mail is deliverable without one, though including it speeds up sorting. The postal code should be written in capital letters.

Look up a specific address

For the code covering one particular street or building, Argentina's postal service publishes an official finder: www.correoargentino.com.ar/formularios/cpa. It is authoritative and kept current, which third-party copies often are not.
