Address formats
If there is no space for office suite number or floor number at the end of the street address line, these should be placed in the line above.

If a post office box number is used in place of a street address, these can be written as 'PO Box 1234' or 'POB 1234'. It is advisable to avoid using both post office box numbers and street addresses. If both are used, the post office box number should be the lower line, and this will be used if mail can be delivered there.

The use of capital letters and the omission of punctuation are not obligatory but are advised.
