The County of Huron is checking again to see if their listings are accurate for the PRISM 911 emergency telephone notification system.
The mass call-out starts on March 7th.
County Emergency Services Chief David Lew says they conduct the call-out on an annual basis by automatically calling each number to make sure the information is still current.
Lew says the number of subscribers to the free service is slowly increasing.
Around 44 per-cent of Huron County households subscribe to PRISM 911 which is about 10 per-cent higher than at this time last year.
Lew says PRISM 911 was used to good advantage in 2010.
Subscribers received 28 calls for emergency notifications ranging from boil-water advisories to police actions in their areas.
Lew encourages you to sign up with PRISM 911 by calling the Huron County office toll-free or by visiting the County website at www.huroncounty.ca/prism
