DEA Number Verification

Please explain how to verify the letters at the beginning of a DEA number?

I understand how to verify the check digit, but the letters I am unsure of. I know it is the type of practice and the last name of the prescriber, but in what order, and sometimes the questions doesn't have the type of practice, so how do I know for sure?

On the DEA Number Verification Page, the last paragraph talks about the letters preceding the numbers.
