How an address is written in Swaziland

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

[Recipient name]
[Street address]
[City]
[Postal code (H100)]
SWAZILAND

A postal code is optional in Swaziland 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, Swaziland's postal service publishes an official finder: www.eswatinipost.co.sz/postcode.php. It is authoritative and kept current, which third-party copies often are not.
