The Inside Address – In a business or formal letter you should give the address of the recipient after your own address. Include the recipient’s name, company, address and postal code. Add job title if appropriate. Separate the recipient’s name and tile with a comma. Double check that you have the correct spelling of the recipient’s name.
The Inside Address is always on the left margin. If an 8 ½ “ x 11” paper is folded in thirds to fit in a standard 9” business envelope, the inside address can appear through the window in the envelope.
