What is CodeRED?

The CodeRED Emergency Notification System is a fast communication service allowing the City of Mayfield Heights to provide mass notification quickly and easily. The system will also be utilized to provide general information such as announcements and cancellations to contact groups by way of email and text messages. This service is free to all Mayfield Heights residents and businesses.

How will I benefit from this service?

This high-speed telephone system will allow the City of Mayfield Heights to contact participants to provide information about a critical situation.

What do I have to do to receive this benefit?

You must register your home, cell phone, or business phone number in the CodeRED database.

How does it work?

CodeRED delivers the important message through a high-speed telephone calling system to a phone number on the CodeRED database. City staff will access CodeRED via a secure portal on the web. A "call area" will be marked identifying street addresses. Telephone numbers will be matched up electronically to these addresses through the use of Geographical Information Systems (GIS). A pre-recorded message will be sent out via the telephone with information about the incident and possibly instructions for action to be taken.

What should I do if I receive a CodeRED message?

* Listen Carefully
* Follow Instructions
* Don't hang up until you hear the whole message
   (the message will not be repeated)
* DO NOT call 9-1-1 unless instructed to do so (You will only tie up emergency lines)

What should I do if I don't receive a message?

Your area of the community may not be affected. In which case, you won't receive a call even if it's only a block away.

Will the system work with cell phones?

Yes. But, your cell phone number needs to be associated with your City of Mayfield Heights address. We encourage you to register your cell phone number.

What is CodeRED used for?

CodeRED will be used for significant incidents and events where the timely notification of an affected population or geographic area is essential.

Why did CodeRED call me several times?

If there is no answer and you do not have an answering device, the number will be attempted up to 3 times.

Why did I get a call, but no message played?

If you answer and do not say hello, CodeRED will not begin playing automatically. It is trying to determine if is has reached a live person or answering device. If you do not say anything, it will hang up and retry the number in the next pass of the non connected numbers.

Why did it leave only part of the message on my answering machine?

CodeRED will leave a message on an answering device. There are many different brands and types of capturing devices for leaving a message. Occasionally something about the answering device or the beep of the device causes the system to think it has reached a live person and begins playing the message. When the message is left, it only leaves part of the message. You can call back the 866-419-5000 and receive the entire message. This does not happen often.

Why does my phone ring once and hang up?

It has called me twice and won't let me answer it. If you have a ring back tone, which plays a song instead of ringing, the system will interpret this as an Operator Intercept and hang up, only to retry the number. You have two options. You can remove the ring back tone or you can contact their cell phone provider and request that the phone number 866-419-5000 be bypassed by this feature.

How Do I Register?

Click the CodeRed logo on the Home Page of our website. The following information is required to add a telephone number into the "CodeRED" database: first and last name; address (physical address, no P.O. boxes); Zip Code; and primary phone number. A primary phone number is most likely the identified home phone number. An alternate phone number, such as a mobile phone, can also be entered and both the primary and alternate line will be contacted in the event of an emergency. The system works with cellular phones but requires a City of Mayfield Heights street address. When entering information, please fill out all of the screens because the newest data entered will replace the old data.

For those who are hearing impaired, the sign up form offers a TDD ONLY option for tone delivery of emergency messages. Messages delivered to phone numbers marked TDD will only be delivered in a TDD/TTY format. Residents without Internet access may call at 440-442-2626 x407 to leave the registration information for input by city hall staff.

What are contact groups?

The system will be used for non-critical communications by way of email or text messages. You may indicate your interest in joining a group by sending an email to This email address is being protected from spambots. You need JavaScript enabled to view it. . The groups are Announcements(camp registration begins tomorrow), Reminders (fireworks tonight at dusk), Cancellations (baseball games are rained out), and Closures (pool is closed due to inclement weather).


Examples of times when the CodeRED system could be utilized: drinking water contamination, evacuation notice, missing person, fires or floods, bomb threat, hostage situation, chemical spill or gas leak, and other incidents where rapid and accurate notification is essential for life safety.
