Links to emergency notification systems for the five-county Houston region are given below. Be aware that not all alert systems will announce every emergency. Some systems are intended only for emergency closure information, and will not provide disaster information. Always rely on multiple sources of information, including local media. Be aware that technical difficulties could prevent the timely receipt of text message or email alerts.

All five counties in the Ready Houston region provide emergency notifications for their residents. If you live in a city, or are affiliated with a school district, college or university, please also check the other sections for additional emergency notification options.

Brazoria County

Fort Bend County

Galveston County

Harris County

Montgomery County



Four of the counties in our region also have Reverse 9-1-1 systems that can reach cell phones and VoIP phones (such as phone service from Vonage). In order to activate Reverse 9-1-1 to your cell phone or VoIP phone, you need to register your phone number and an address. Residents with land lines (traditional telephones) are already in the Reverse 9-1-1 system and do not need to take any action for those phone lines.

Brazoria County currently does not provide Reverse 9-1-1 service to cell phones or VoIP lines.

Fort Bend County Reverse 9-1-1

Galveston County Reverse 9-1-1 – except City of Galveston

City of Galveston Reverse 9-1-1

Harris County Reverse 9-1-1

Montgomery County Reverse 9-1-1

Except for the City of Galveston, the county cell phone and VoIP Reverse 9-1-1 registries also cover all cities wholly or partially inside those counties. All systems are administered by the jurisdiction listed, or that jurisdiction’s contractor. The Houston Urban Area Security Initiative does not administer any of the systems listed above and cannot address technical questions, registration issues, or other problems.
