To address an envelope correctly, you'll need to include both the sender's return address and the recipient's address. Here's how to format both addresses on the envelope:
1. **Sender's Return Address:**
- Write the sender's return address in the top-left corner of the envelope. This ensures that the mail can be returned to you if it's undeliverable or if there are any issues with delivery. Include your full name, street address, city, state, and ZIP code.
2. **Recipient's Address:**
- Write the recipient's address in the center of the envelope, slightly to the right. Include the recipient's full name or the name of the person or organization you are sending the mail to. Write the street address or P.O. Box number, apartment or suite numbers if applicable, city, state, and ZIP code. If you are sending mail internationally, include the name of the destination country as well.
Make sure to write both addresses clearly and legibly using dark ink to ensure that they are easy to read. Avoid using cursive or elaborate fonts that may be difficult to decipher, especially for automated sorting machines.
By including both the sender's return address and the recipient's address on the envelope, you can ensure accurate delivery and provide a way for the mail to be returned to you if necessary.
