Police response to alarms, by force area
Which force covers your address determines who issues your URN, what it costs, and the false-alarm threshold you are held to.
A Unique Reference Number is issued by the police force covering your address, not nationally and not by your installer. Fees and false-alarm thresholds are set locally, so the force covering you is a practical detail, not trivia.
