Customer Reviews
Salvatore S.
Advanced user of Lob Address Verification APIThe real-time address verification has been a huge value add for our software platform. An additional feature that sets us a part is being able to implement the auto-complete feature into our checkout process. The Lob team has been amazing, we consider them a critical feature and partner for us.
The only downside is that we can't validate international addresses via autocomplete in real-time. We realize they are working on a solution for this, but that it is not very easy to do.
This platform is a no-brainer. Little reason to look elsewhere!
Our clients are nonprofit organizations. Having poorly entered addresses filling their database and CRMs is a major painpoint that we're able to now solve for them. The implementation is seamless and they realize an immediate benefit. When we tell our prospective clients what we're able to do for this via Lob, this often is a "closer" feature that blows their mind.
