To create a Ford Marketplace account, navigate to https://fleetaccount.ford.com/third-party-signup and enter your details. Ensure you select Verizon Connect as your service provider.
Once your account is created, you might need to provide additional information to Ford in order for your Ford vehicles to be connected to your account. Once they are in your account, select the "Add Consent" option and choose Verizon Connect as the service provider.
After you have created your Ford Marketplace account, ensure that Auto-Consent is enabled. Doing this allows all vehicles added in future to be consented automatically to Verizon Connect.
