Questions about Leslie's license

Is Leslie W. Kostner a licensed insurance agent in Texas?

Public licensing records list license 1537187 with a status of "Active", first issued in 2008, expiring August 31, 2027. We last checked the record against public licensing records on November 1, 2026. A license means the state allows the agent to sell insurance; it is not an endorsement.

How do I verify this license myself?

Search the state's insurance agent lookup by name or license number 1537187, or look up National Producer Number 4918623 on the NIPR website. Both are free and show the current status.

What does a carrier appointment mean?

An appointment is the insurance carrier's authorization for the agent to sell its products in Texas. Records show 18 appointments for Leslie. It does not tell you which plans the agent will recommend, and it is not a rating.

Does it cost anything to contact Leslie?

No. Licensed agents are paid by the insurance carrier when you enroll, and your premium is the same whether you use an agent or not. MeetBrokers does not charge you either.
