A Guide to Addressing a Letter Correctly

To address the letter correctly, you have to include the following info on the front of the envelope:

  • Mailing address
  • Return address

Another requirement is to place the right number of stamps in the top-right corner of the envelope. You can calculate how many stamps you need by:

  1. Measuring your letter’s height, length, weight, and thickness
  2. Using an online postage calculator to determine the cost of mailing your letter
  3. Dividing the postage price by the price of one Forever Stamp (currently $0.55)

How To Write a Proper Mailing Address

The mailing address has to be in the middle of the envelope, and it needs to contain the recipient’s info:

How To Write a Letter—Letter Formatting 101

While you don’t need to worry about letter structure when sending mail to your loved one, writing formal letters is much more complex.

If you want your letter to be professional, you have to respect certain formatting rules and include the following sections:

  1. Your info—begin your letter by writing your name, address, phone number, and email address either in the top left corner of the letter or on the letterhead
  2. Date—include the date of writing the letter
  3. Reference line (Re:)—this section is optional, and it’s typically used when responding to another letter or a job ad

    • Title and name
    • Company (if applicable)
    • Address of the company or the recipient
    • City, state, and ZIP code
  5. Salutation—to address the recipient, choose one of the following formal greetings:
    • Dear Mr./Ms./Dr. + last name
    • Dear Hiring Manager
    • Dear + full name
    • Dear Sir or Madam
    • To Whom It May Concern
  6. Introduction—the first paragraph should offer a short explanation of why you’re writing the letter. If you’re writing to the recipient for the first time, you should introduce yourself in the first sentence
  7. Body of letter—this is the main section of your letter, and it should contain more details regarding your request or the information you’re sharing
  8. Conclusion—in the last paragraph, you should:
    • Thank the recipient for his or her attention
    • Politely ask for his or her answer
