Addressing letters correctly is important to ensure that they reach the receiver in the minimum amount of time and are directed to the correct location. Improper addressing can result in the letter being delivered late or not at all. The usual format is to write the address starting with the most specific item -- the name -- at the top of the address and working your way down to the broadest item.
Write the name
Write the name of the receiver at the top of the address.
Write the person's
Write the person's department or title if they have one. Write the company or institution name underneath, if necessary. For example:
Marketing Director Fresh Toys Ltd
Marketing Director Fresh Toys Ltd.
Write the street address
Write the street address or post office box number. For example, 23 Windsor St.
Write the town name
Write the town name, followed by the state. For example, New York, NY.
Write the ZIP code
Write the ZIP code.
Write the country name
Write the country name if sending internationally. A complete address would look like this:
John Doe Marketing Director Fresh Toys Ltd. 23 Windsor St. New York, NY 10017 USA
Many international postal services ask that you write the town name, state or province and country in upper case letters. In fact it is preferred that all the address is written in the upper case to make it easier to read.
