In our Additional Information section, we allow you to ask your payers to enter their physical address. If you would like, you can choose to verify US-based physical address with the United States Postal Service. In order to do so:
1) In the Additional Information section, choose the field type as Address
2) Choose "Yes" to "Verify US Address?"
3) Save the form field as well as the form itself
4) Now, at checkout, we will verify the US address
