CodeRed Information



CodeRed Notification Service 

The Town of Grantham is proud to offer CodeRED® a emergency alert system that relays information to residents by telephone.  In an emergency situation, the high-speed messaging system can deliver customized emergency notifications and instructions at a rate of 60,000 calls per hour. 

Residents whose phone number is listed in the white pages of the telephone directory are automatically included in the database to receive CodeRED® messages.  However, business and residents with non-listed numbers must register if they wish to receive the CodeRED® emergency notifications.  Residents should register if they:

  • Want their cell phone called  
  • Want to provide a work phone as a back-up to their home phone    
  • Want to provide a caregiver back-up number  
  • Recently moved and kept their old phone number  
  • Have changed their phone number in the past six months  
  • Use a TDD/TTY

How Does CodeRED Work?

CodeRED® employs a one-of-a-kind Internet mapping capability for geographic targeting of calls, coupled with a high-speed telephone calling system capable of delivering customized, pre-recorded emergency messages directly to homes and businesses at the rate of up to 60,000 calls per hour. CodeRED® subscribers control their emergency broadcasts from anywhere in the world via a secure Internet Portal. 

The CodeRED® system is a geographical based notification system, which means street addresses are needed to select which telephone numbers will receive emergency notification calls in any given situation.  The system works fine for cellular phones too, but requires a street address.  People who have recently moved but kept the same listed or unlisted number also need to change their addresses in the database. 

The information is used for emergency notification purposes only
