Addressing an envelope is an important matter in processing letter. That’s why we need to know the right way to addressing an envelope. Here are a few simple rules about the best way of addressing an envelope you have to know.
The number precedes the street name. Words like street, square, avenue are written separately, each word starting with a capital letter.
Commas may be placed at the end of each line (closed punctuation), or only between city and state or county (open punctuation). Use the same form as in the letter.
The British postcode is written below the address. The American zip code is on the same line as city and state.
The postcode should always be the last item of information in the address and in block capitals.
Whenever possible place the postcode on a line by itself at the end of the address.
When an address formerly included Postal District letters and / or numbers, these will usually be incorporated in the postcode.
Do not use full stops or any other punctuation marks between or at the end of the characters of the postcode.
Always leave a clear space, at least equivalent to one character, between the two halves of the postcode.
Never underline the postcode.
Never join the characters of a postcode in any way.
No writing should appear below the postcode. It is better to show return addresses on the back of an envelope rather than in the bottom corners of the front. “for the attention of … “ and similar messages should be shown above the address, not below it.

110, North Street,
If you use private reference numbers on letters for your own purposes, they too should be placed immediately above the address, or be kept to the upper left hand side of the address panel.
