CodeRed Annual All Call Test

The Jefferson County Emergency Communications Authority (JCECA) will test CodeRED, the emergency notification system, on behalf of Jefferson County law enforcement, fire and emergency medical service agencies on Wednesday, Dec. 11, 2019.

Starting at 9 a.m., the CodeRED emergency notification system will begin making test notifications on all landlines, as well as registered cellphones and emails. This process is expected to take several hours due to the large number of notifications.

Landlines are automatically included in CodeRED notifications, but residents and businesses are encouraged to visit the CodeRED registration website for Jefferson County BEFORE December 11 to add contact information, including cellphone numbers, SMS (text) and email address preferences. Residents may also elect to receive severe weather notifications.

Registration is especially important for those addresses without a landline, as individuals must register if they want to receive emergency notifications. 

The CodeRED system is used by emergency service agencies in Jefferson County to help disseminate important information regarding critical incidents.

How it Works

A CodeRED notification recording will let you know it's a message from the Sheriff's Office. CodeRED caller identification should display 'EMERGENCY COMM' and the phone number 866-419-5000 (text messages come from 76993, which you may program into your contacts list).

CodeRED also works with a telecommunications device for the hearing impaired (TDD).

If the line is busy, CodeRED will keep calling back. CodeRED will attempt to leave a message. If you don't get a message, or would like to hear it again, call 866-419-5000 to receive the last message sent to your area.

The App

CodeRED also has an emergency notification app. Unlike the database, the CodeRED app will give you notifications when you are in geographic proximity to a warning area. For instance, you might visit a friend or family member who is within the warning area. The app will detect your proximity and provide you the same warning given to those who live and work in that area.


CodeRED reaches numbers from two databases. One is the 911 database, which contains all listed and unlisted land lines in Jefferson County. If you have a land line, it is automatically included in this database.

The second database is made up of Voice over Internet Protocol (VoIP*) numbers (if you have a bundled internet / phone / television service you probably have a VoIP line), and email addresses owned by people who have opted in to receive the calls.

If you don’t have a traditional land line phone, and would like to receive a text, email or cell phone call in addition to the call on your land line phone, consider registering for this free service. To register, visit the CodeRED phone registry.

Through the CodeRED cell registration you can add additional numbers and locations to your profile. For example, if you work in Jefferson County, you may want to add your work address to your profile so you receive notifications related to incidents in that area.


Individuals and businesses can cancel the register of phone numbers and email addresses to prevent emergency notifications. To opt-out of CodeRED messages visit their website. You can also visit the registration page and modify your profile without completely opting out of notifications.

You can also opt out of certain notifications via this link as well.
