If you are on the Monthly Subscription Starter or Basic plans, a calling name will be chosen based upon your company’s legal name as defined during the business certification process.
If you are on a Premium plan, when you are setting up a new program you can choose Create Custom Display Name. This will allow you to choose a custom name based upon your company, department, or even calling purpose. If your Custom Display Name does not follow First Orion’s Branding Policy, you can expect a minimum of a 24-hour delay.
You may try to appeal the decision.
