Business Letters: Format
When business letters are written on company letterhead stationery, they are generally formatted in a full block style with each part of the letter justified to the left margin.
Letters not on company letterhead stationery are written in a modified block style with the heading, date and complimentary close left justified to the center line and the inside address, salutation and body justified to the left margin.
When a business letter requires more than one page, the secondary pages should have a header that includes the recipient's name, the page number and the date.
