Quick Answer

To write an envelope, put the recipient name and address in the center, your return address in the top-left corner, and the stamp in the top-right corner. Use clear block letters, include apartment or unit numbers, and verify the ZIP or postal code before mailing.

What You Need

  • Envelope
  • Pen with dark ink
  • Recipient full address
  • Return address
  • Correct postage
  • Optional address label

Safety Precautions

  • Do not write sensitive account numbers or private notes on the outside of the envelope.
  • Verify addresses before mailing legal, financial, or time-sensitive documents.
  • Use tracking or certified mail when proof of delivery matters.
  • Check postal rules for international mail.

  2. Step 2

    Write the recipient name

    Put the person or business name in the center area.

  3. Step 3

Common Mistakes

  • Forgetting apartment number
  • Putting return address in the center
  • Using hard-to-read handwriting
  • Missing ZIP code
  • Wrong stamp amount
  • No country name for international mail

Troubleshooting

The address is too long

Use separate lines for business name, street address, unit, city, state, and ZIP.

You made a mistake

Use a new envelope or a clean address label instead of scribbling heavily.

Mail was returned

Check the address, ZIP code, postage, and whether the recipient moved.

You need delivery proof

Use tracked, certified, or registered mail based on the document importance.

FAQs

Where does the stamp go?

The stamp goes in the top-right corner on the front of the envelope.

Where does the return address go?

The return address usually goes in the top-left corner.

Do I need a return address?

It is strongly recommended because undeliverable mail can come back to you.
