HOAX 999 callers face having their mobile phones disconnected.
And they may also be prosecuted for making the malicious calls.
The new strategy used by West Yorkshire Fire And Rescue Service involves close liaison between them and major mobile phone companies.
A hoax call was made on Monday evening which sent a fire engine to a supposed school fire in Wyke, Bradford.
The call was found to be a hoax and within hours the phone from which it was made was cut off.
A spokesman for West Yorkshire Fire and Rescue Service said the number of malicious calls had fallen in recent years as the people who made them realised they could be traced and prosecuted.
But still there were 2,321 hoax calls to the county's fire service over the last 12 months.
A West Yorkshire Fire And Rescue Service spokesman said: "All the main mobile phone companies have now agreed to cut off phones which are used to make malicious calls.
"We've had many reports of mobile phones being disconnected in this way in West Yorkshire."
All 999 calls are recorded and the operators know immediately which phone number it is coming from.
A West Yorkshire Police spokeswoman said:
"Positive action can and will be taken against those callers committing a criminal offence."
