A requirement of the NICS Denial Notification Act of 2022, is a requirement that the FBI NICS notify the local PD of the denial. Being that an unincorporated area may also bear the name of an incorporated area, the FBI asks "Reside in city limits" so they know whether to notify the city PD or county.
Thanks, Dogtown Tom, that was a clear and consise, non-conspiratorial answer!
