Each agent must at all times keep the Texas Department of Insurance informed of the agent's current address. Such address must be included in each license application and each license renewal form. In the absence of the submission of a specific written request to change that address, which must be separate from any other submission, the agent's current address is presumed to be the most recent address on file with the department. Such address will be considered the agent's last known address for the purposes of notice to the agent by mail. Any request for a change of address must be made using the instructions provided on the department's website.
