Sort Kentucky from Indiana in the first thirty seconds of the call
The state a caller is standing in changes whether the job is yours at all, so it belongs before the symptom, not after the address.
Put it in the script as the second question, right after what is happening. Are you on the Kentucky side or over in Indiana. Callers answer that instantly, and it costs you nothing.
If the answer is Indiana and you do not work there, the call is not a failure. It is a referral, done fast and warmly. Have a name ready. People remember who helped them at eleven at night, and their neighbor in Clarksville is not your customer anyway.
If you do work both sides, the answer changes the routing, the crew and sometimes the arrival window. Getting it up front stops the truck from being assigned twice.
Log the state on every inquiry. Without it, your reporting averages two markets with different travel times and different economics into a single number that describes neither.
