Oman Postal Codes

Oman uses postal codes in the format ### (# = digit). A complete public code list is not published under an open licence, so this page gives the verified format and real examples rather than an unverified table.

Example postal codes

• 133
• 112
• 111

Finding a specific code

The national postal operator is the authoritative source for a specific street or building in Oman. Codes quoted on third-party sites are frequently out of date.

How an address is written in Oman

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

[Recipient name]
[Street address]
[Postal code (133)]
[City]
OMAN

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