Sign Up for Waltham Emergency Alert Notifications!

The City of Waltham has implemented CodeRED, a high-speed emergency notification solution provided by Emergency Communications Network to help keep residents and businesses informed with important information that may immediately impact their safety. To see how the CodeRED system works, click here.

Please note: If you are unsure of whether your contact information is in the emergency database, or you have recently moved or changed your telephone number, it is important to visit the enrollment page to add or update your information.

The City of Waltham will use the CodeRED system to notify the entire city, or specific areas within the city depending on the emergency. The CodeRED system will deliver telephone calls, text messages and emails. Messages may regard evacuations, police activity, missing children, boil water notices or other information. Please listen to the message carefully.
