Address a business letter by placing the recipient’s name, title, company, and full address in a block at the top left, followed by the date, and then a formal salutation such as “Dear Mr. Smith:” or “Dear Dr. Jones:”. Use the person’s full name and title exactly as they sign their correspondence, and always include a colon after the salutation in standard US business format.
Why the Inside Address Matters
The inside address is the recipient’s address as it appears on the letter itself, not just the envelope. It serves three practical purposes: it confirms the letter reaches the right person if the envelope is damaged, it gives the reader an immediate reference for filing, and it signals that you have taken care with details. In a business context, a letter with a missing or sloppy inside address reads as careless, even if the content is strong. The address block should match the official spelling of the company name and the person’s job title. For example, if the person is “Director of Operations,” do not abbreviate it to “Dir. of Ops.” unless you know that is how they refer to themselves.
Standard Block Format for Business Letters
Most business letters use full block format, where every line starts at the left margin with no indents. The order is:
- Your return address (or company letterhead)
- Date (spelled out, e.g., “March 3, 2025”)
- Recipient’s name and title
- Company name
- Street address or P.O. Box
- City, state, and ZIP code
- Salutation (with a colon)
- Body paragraphs
- Closing (e.g., “Sincerely,”)
- Your signature and printed name
Leave one blank line between each of these elements. If you do not know the recipient’s name, use a general salutation like “Dear Hiring Manager:” or “Dear Customer Service Team:” rather than “To Whom It May Concern,” which sounds outdated. When you do know the name, the salutation should match the gender and title the person uses. If the name is gender-neutral or ambiguous, use the full name: “Dear Jordan Lee:” is acceptable and avoids assumptions.
How to Address Different Recipients
The correct form depends on the person’s role and your relationship. For a first-time business contact, use a formal title and last name. For a person with a doctorate, use “Dr.” in both the address and salutation. For an attorney, use “Esq.” after the name in the address block, but use “Mr.” or “Ms.” in the salutation. For a married couple who share a last name, write “Mr. and Mrs. John Smith” only if you know the wife uses her husband’s name; otherwise, list both full names on separate lines. When writing to a company rather than a person, address the letter to the specific department, e.g., “Accounts Payable Department,” and use “Dear Accounts Payable Team:” as the salutation.
Common Mistakes and How to Avoid Them
The most frequent errors are misspelling the recipient’s name, using the wrong title, and placing the date in the wrong spot. Another common mistake is using a comma after the salutation; in US business letters, a colon is standard. In UK and other Commonwealth formats, a comma is acceptable, but if you are writing to a US company, use the colon. Also, do not abbreviate the state name in the inside address unless you are using the two-letter postal abbreviation, which is preferred. Avoid writing “Attn:” on the first line of the address; instead, put the person’s name on the first line, then the company, then the street. Finally, never use a nickname unless the recipient signs their letters that way. If you have only seen “Robert” in a signature, do not write “Bob.”

Envelope Addressing vs. Inside Address
The envelope should carry the same recipient information but in a slightly different format. On the envelope, place the recipient’s name on the first line, the company on the second, and the street address on the third. Use the two-letter state abbreviation and the ZIP+4 code if you have it. The return address goes in the upper left corner. Unlike the inside address, you may use “ATTN:” on the envelope if you are sending to a company and want a specific person to receive it. However, the USPS recommends putting the person’s name on the first line, not “ATTN.” For international mail, include the country name in capital letters on the last line. The inside address and the envelope address should match exactly; any discrepancy can delay delivery.
Frequently Asked Questions
What if I don’t know the recipient’s gender?
Use the full name in the salutation, such as “Dear Taylor Smith:” or “Dear Chris Johnson:”. This is professional and avoids assuming. If you only have an initial, write “Dear J. Smith:” or better, call the company to ask for the correct name.
Should I include my own address in a business letter?
Yes, if you are not using letterhead. The return address at the top tells the reader who is writing and where to reply. If you use company letterhead, that already contains the address, so you only need the date.
Is it acceptable to use “To Whom It May Concern”?
It is acceptable only when you truly do not know the recipient’s name or role, such as a general inquiry to an organization. However, it is impersonal and often seen as lazy. Try to find a specific name on the company website or LinkedIn, or use “Dear Hiring Manager:” for job applications.
How do I address a letter to a doctor or a judge?
For a medical doctor or PhD, use “Dr.” in the address and salutation. For a judge, write “The Honorable [Full Name]” on the envelope and “Dear Judge [Last Name]:” in the salutation. For a military officer, use their rank, e.g., “Colonel [Last Name].”
What is the difference between a business letter and a personal letter format?
A business letter uses a block format, a colon after the salutation, and a formal tone. A personal letter typically uses an indented format, a comma after the salutation, and a more casual tone. In business, you also include a typed signature line and often a reference line or subject line.
Should I use “Mr.” or “Ms.” for a woman whose marital status I don’t know?
Use “Ms.” unless you know she prefers “Mrs.” or “Miss.” “Ms.” is neutral and widely accepted in professional correspondence. If she has a professional title like “Dr.” or “Professor,” use that instead.
