How to Write an Address on a Letter (USPS Format)

Writing an address may seem simple, but mistakes can delay your mail or get it returned. Here's how to format sender and recipient addresses properly, according to USPS standards.

1. Add the Return Address

Your return address should go in the top left corner of the envelope (or top of the letter). Include:

• Your full name
• Street address
• City, state, ZIP code

2. Format the Recipient’s Address

Write the recipient’s address centered on the envelope. Use this format:

• Recipient’s full name
• Street address (include apartment or unit #)
• City, State ZIP code

3. Common Addressing Mistakes

• Omitting apartment or suite numbers
• Incorrect or missing ZIP codes
• Writing addresses too close to envelope edges
• Using non-standard abbreviations or lowercase
