How to Properly Address an Envelope

It may seem old-fashioned in an age of digital communication, but addressing an envelope is an important skill for both personal and business correspondence. Whether you are mailing a handwritten letter or a formal memo, learning how to address an envelope correctly ensures your mail reaches the intended recipient.

Steps to Address an Envelope

Recipient's Information

The most important aspect is to have the full name of the recipient, along with their complete address, including street, city, state, and zip code. This information should be printed clearly and legibly to prevent any postal errors. Typically, the recipient's address is centered on the envelope.

Addressing for an Apartment Number

If you are wondering how to address an envelope for an apartment number, keep it simple. Write the street address on one line, followed by the apartment number on the next line. For example:

John Doe
123 Main St.
Apt. 4B
New York, NY 10001

Separately placing the apartment number on its own line ensures readability and reduces the chance of delivery mistakes.

Sender's Information

Lastly, include the sender's details. The return address should be in the top left corner of the envelope. This step is crucial because if there is a delivery issue, the mail can be returned to you. Be sure to include your full name, address, city, state, and zip code.

Using 'Attn' for Specific Recipients

To address an envelope with 'Attn,' include the contact name of the person or department you want the mail delivered to on its own line, as shown below:

Jane Smith ATTN:
ABC Corporation
456 Business Rd.
Los Angeles, CA 90012

This method is the best way to ensure your mail reaches the correct person when dealing with an organization or large company.

Additional Tips

  • Opt for better quality stationery and use a pen that does not smear.
  • If possible, use a typewriter or printer for a professional appearance.
  • The U.S. Postal Service recommends using all caps when addressing envelopes. This practice makes your address easier to read and reduces the chance of errors by the Optical Character Recognition software used by postal services.

In short, always address envelopes correctly as it reflects your communication skills. Whether you are sending a personal note or a business letter, these guidelines will ensure that your mail arrives at its destination. With any pen in hand, you can confidently address an envelope properly moving forward.
