Franklin police said anonymous tips are making a big impact on crime.
Many of the Franklin Police Department's tips are sent to them through text messaging.
Franklin's 911 call center started accepting text messages through a program that does not allow them to see the person's phone number.
Since 2009, the number of tips police get each year has more than doubled.
"Every year our tips are getting bigger and better," said Lt. Charles Warner.
The call center was the first in Tennessee to start this program.
To text a tip to Franklin police, text 615-847-411 and within the message, type ‘615FPD' followed by the tip.
Anyone who wishes to submit an anonymous tip can also do so on their Web site or call Crime Stoppers at 615-794-4000.
