Yes, you'll just need to set up a subaccount under your main account to host your second (or third, or fifth) long code.
With any paid monthly plan, you can create separate subaccounts under your main account. As each subaccount is a separate account, you'll be able to create a new long code for each one.
For example, our $99/mo plan includes four subaccounts, meaning that you can have five long codes (one in your main account and one for each of your subaccounts).
For more on how to create a long code, check out this guide.
