You don't need a license, but you will need to be certified with FedEx to ship directly with them. You can use ShipYourReptiles.com, and you will be shipping under our certification. You must meet our Shipping Standards, which meet the FedEx standards, and include guidelines for things like packaging (at least 3/4" insulation) and temperature parameters (including heat pack use).
We also offer On-time and Live Arrival Insurance, the only way to insure your animals through any carrier, and rates start at 20% off the FedEx retail rate. We have a detailed Get Help section to walk you through the process, but feel free to contact us directly if we can answer questions for you! Info@ShipYourReptiles.com.
