License Applications | Sircon powered by Vertafore

When you click on TEXAS you will then select 'GENERAL LINES AGENT" then "PROPERTY AND CASUALTY"

You do not need any sponsoring agent or agency.

There is a place to enter your National Producer Number (NPN). If this is your first license, you don't have one yet - so skip it. If you already have a Life License, then you have an NPN and can enter it. If you don't have a business address, you can use your home address twice, no problem. Just be sure to update your record later, if you do get a business address.
