The non-emergency number 101 is now the main phone number for the police if your call is not urgent.
The longer non-emergency number 0845 33 00 222, which ran alongside 101, was scrapped on Monday because police chiefs now hope most people know about the shorter number.
Supt Owen Weatherill said: “Since 101 was launched, calls made using 999 for non-emergencies have greatly reduced.”
The number 101 is a round-the-clock service. For emergencies, still dial 999.
