    CodeRED: Why We’re Calling You in an Emergency

    In Jefferson County, the CodeRED emergency notification system allows us to call citizens to warn them of danger. With CodeRED, we can simultaneously call, text, or email, multiple phones within an area that we designate, to warn residents of flood, fire, tornadoes, chemical spills, or dangerous suspects. Within moments, calls reach the affected community to deliver warnings and critical safety instructions.

    If you receive a CodeRED call, the voice on the line will let you know it's a message from the Sheriff's Office. Also, your caller ID should display our agency's name and a call-back number. The CodeRED system works with all phones that have a TDD line (for the hearing impaired). If you have a telephone zapper used to block out telemarketers, or if your phone is blocked to unknown callers, you will not receive CodeRED calls.

    Opt-In to CodeRED

    Jefferson County residents and businesses can register their mobile phone numbers or Voice over Internet Protocol (VoIP) phone numbers to receive emergency notifications. "Landline" phones are automatically included in the CodeRED database for each emergency agency.

    CodeRED reaches numbers from two databases. One is the county’s 911 database, which contains all listed and unlisted land lines. If you have a land line, it is automatically included in this database. The second is a database of mobile phone and VoIP* numbers — established in 2009 — whose owners have opted in to receive the calls. If you don’t have a traditional land line phone, or 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 External Link Icon.

    *Voice over Internet Protocol, or VoIP, are "telephone" communications transmitted over the Internet, instead of traditional phone lines. If you have a "bundled" internet/phone/TV service, you probably have a VoIP line.
