CAMBRIDGESHIRE police can now be contacted on 101 for all non-emergency calls.
The number came into use on September 21 and in the first month 3416 calls were received.
The old 0345 number will remain in use alongside 101 for several months to allow people time to get used to the new number.
The number change is part of a national scheme to make 101 the single non-emergency number in England and Wales.
The change has been introduced so residents will have one easy-to-remember way to contact local police wherever they are.
The system has been designed to recognise where the caller is dialling from and connect them with the local police service.
If a caller does not want to speak to their local force they will be given the option to be connected to different one.
Superintendent Paul Fullwood said: “The number change does not affect the way that calls are handled.
“Cambridgeshire police continue to take non-emergency calls 24 hours a day, seven days a week.
“People should continue to call 999 when an immediate response is needed because a crime is happening, someone suspected of a crime is nearby, or someone is in danger.”
