When would someone perform a USPS Address Lookup?
From what we’ve learned over the years, people and businesses perform address lookups for many reasons.
These are the most common reasons for usps lookups:
- Zip code lookup by address: you might need to do this if you have an incomplete mailing address that is missing a zip code.
- USPS change of address: if you know someone has recently moved, but you don’t have their new, mailing address.
- USPS address lookup by name: if you have someone’s name, but not their current mailing address.
- USPS lookup by address: if you need to find the Name of the person or people who live at an address
What is the correct USPS approved address format?
When you add an address to your mail piece, it needs to be in the correct, USPS approved format. If you don’t address your direct mail piece correctly, the postal service might mark your mailing piece as undeliverable and will not deliver it.
Here’s an example of how to correctly address a mailing piece to someone at a residential home:
First and Last Name
Street Number + Street Name, Building Number / Apartment #
City State Zip code
Here’s an example of how to correctly address a mailing piece to a company:
Contact Name & Title (if applicable)
Street Number + Street Name, Building Number / Suite Number
City State Postal code
