Address verification

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.

  • Where can Lob verify addresses to?
  • What are some address verification use-cases?
  • What is CASS™ Certification and does Lob support it?
  • Can Lob look up zip codes?
  • How often does Lob update their address verification API?
  • For international address verification, can I use that country’s native language and will your API return it in the same language?
  • Why are my verified addresses returning in capital letters?
  • How do I keep track of the amount of verifications I’ve done?
