USPS advises its customers to use the following addressing standards to improve delivery success. If you have questions, visit the USPS website.*
- Type or machine print all address information using a sans-serif type.
- A font point size between 8 and 12 is recommended.
- Use uppercase characters throughout the address.
- Left-justify every line in the address block.
- Leave one or two spaces between words and between the state abbreviation and ZIP Code.
- Include floor, suite and apartment numbers whenever possible.
- Put the city, state and ZIP Code OR Country on the last line. If there is not enough room, you can put the ZIP Code alone on the bottom line.
- Do not print anything below the zip code
- Use standard two-letter state abbreviations.
- Use the appropriate ZIP+4 code. If unknown, use the proper 5-digit ZIP Code.
- When using window envelopes, make sure the complete address is always visible, even when the insert moves.
- Ensure address characters do not touch or overlap and that the print is clear and sharp. Black ink on a white background is best.
