Whenever you enter a US address in SendPro, you’ll be prompted to verify it by clicking a Confirm Address when you click the down arrow button. You’ll encounter address verification when entering recipient or sender address information, creating a shipping label, or adding an address to the Address Book.
If SendPro finds a close match in the USPS database, you’ll have the option of using that instead of the address you entered, editing your entry, or using the address you entered as is. To accept the USPS-verified address, click the Use Verified button when prompted. SendPro will save any edits you made to the address you entered.
