USPS® valid address
A USPS® valid address is an address that abides by United States Postal Service standards and formatting.
When addressing mail within the United States, it is important to adhere to the USPS® valid address format. While many believe that they know the appropriate way to address an envelope or package, a USPS® valid address has features that are not commonly followed by the majority of mail senders.
A USPS® valid address contains the following:
- All capital letters
- A valid and deliverable address
- Included company name, apartment number, or suite number if applicable
- Valid USPS® acronyms and abbreviations
- A valid ZIP+4®
- No commas or periods
The example below shows a USPS® valid address:
123 N MAIN ST STE 45
BOSTON MA 02110-1615
Ensuring that an address is a USPS® valid address is an important step in reducing amounts of returned mail and improving mail delivery time.
