International addresses

The Universal Postal Union is the official international source for postal address formats.

When following their guidance, please bear in mind that the official postal authority's view of an address may be unacceptable to some customers for political, social or emotional reasons.

In mid 2001, we had some difficulties accessing the UPU's list of address formats, and we hosted a copy here with their permission. We believe that issue is now resolved, so please refer to the original source for this information.
