Put an apartment, suite, or unit on the delivery-address line when it fits. Spell the street and city correctly, use the standard two-letter state abbreviation, and include the ZIP Code. Avoid punctuation and decorative fonts if they make the address harder to read.

Final Check

  1. Confirm the recipient and unit number.
  2. Keep the address away from graphics and the envelope edge.
  3. Seal the envelope and check its final weight and shape.
  4. Apply postage flat in the upper-right corner.
  5. Use international formatting and country names for mail sent abroad.

Sources and Scope

Address format does not determine the postage category; also check the finished envelope.
