T here are some basic rules to be adhered to when writing the name and address on an envelope.
When writing to a German-speaking country from Britain you should always include the international abbreviation . The country to which you are writing should go on the very last line of a letter abroad. The Austrian post office's guide to addressing an envelope states that no blank lines should be included on an envelope. In typed or printed business mail however there is often a blank line before the place on an envelope.
