Address Verification APIs

Address Verification APIs verify each recipient's address and ensure proper formatting. Any address can be verified in a matter of seconds, and a Lob confidence score is given (e.g., 100% likelihood of being deliverable). Lob’s Address Verification APIs ensure that your addresses are deliverable and everything you send arrives at the right place, at the right time—every time.
