430 Improperly Prepared Mail

431 Insufficient Address

If an item is improperly addressed, but the country of destination is legibly written, dispatch it to the exchange office. The exchange office will determine whether the address is sufficient.

Note: Due to heightened security, many foreign postal administrations require complete sender and addressee information in roman letters and arabic numerals on postal items.
