Parts of a Business Letter

Every business letter follows a consistent structure. Each part serves a specific purpose and must appear in the correct order on the page.

• Sender's address (also called the return address). Write your full name, street address, city, state, and ZIP code at the top. If you use company letterhead, skip this part.
• Date line. Place the date two lines below the sender's address. Use the full month, day, and year (for example, June 17, 2026).
• Inside address. This is the recipient's name, title, company name, and mailing address. Include it two lines below the date.
• Salutation. Begin with "Dear" followed by the recipient's title and last name, then add a colon. For example, "Dear Mr. Smith:" is the standard form. Use "Dear Hiring Manager:" when you do not know the name.
• Body paragraphs. State your purpose in the first paragraph. Provide details and supporting points in the middle paragraphs. Keep sentences short and direct.
• Closing. End with a polite phrase such as "Sincerely" or "Respectfully," followed by a comma. Leave four lines for a handwritten signature, then type your full name and title below.
• Enclosure notation and initials. If you include additional documents, type "Enclosures" or "Enc." at the bottom. Typist initials (lowercase) go below the closing when someone else typed the letter.

Three Common Business Letter Formats

The three main types of business letter format differ in how they align the text on the page.

• Block format. All text starts at the left margin. This is the most widely used style in American business writing. Paragraphs are not indented.
• Modified block format. The date line, closing, and signature block are centered or shifted to the right half of the page. The body paragraphs still start at the left margin.
• Semi-block format. Similar to modified block, but the first line of each body paragraph is indented. This style is less common in modern business communication.

Tips for Writing a Professional Business Letter

A strong business letter is clear, concise, and free of errors. Follow these guides to make your letter stand out.

• Use standard fonts like Times New Roman or Arial in 12-point size.
• Set one-inch margins on all sides of the page.
• Proofread for punctuation, spelling, and grammar mistakes before sending.
• Keep the tone formal but friendly. Avoid slang or overly casual language.
• Limit the letter to one page when possible. A focused letter gets better results.
