Tips for USPS addressing:
Most US mail is handled automatically, and the address on your mailing piece will most likely be scanned and ‘read’ electronically.
To ensure your mail is easy to scan, the USPS offers these suggestions when addressing your mailpiece:
- use capital letters
- don’t use any puctuation
- allow two spaces between state and ZIP Code
