Flowroute Supported Three-digit Dial Plans

Flowroute supports three-digit dial plans as regulated by the FCC and are offered for use in our services. 

Included in this suite of dial plans:

711 - Text Telephone (TTY) services are also supported by Flowroute. These services are provided for the deaf and hard of hearing population which requires and relies on having additional assistance in voice services. TTY makes it possible for the deaf and hard of hearing to successfully make phone calls to users of regular phone systems.

911 - The E911 emergency services are provided as regulated to customers who have designated the outbound number with an E911 profile. To make use of this service, you must have an existing E911 address set up in Flowroute DID page in the Manage Portal. Once the E911 service has been set up, this dial plan will allow for the correct emergency services to be contacted in an event to which they need to respond.

933 - Used to test your E911 address which was previously set by the E911 service option in the Flowroute Manage Portal under E911. When you dial 933 you will be connected with an automated system that will read back to you, the address you have currently on record for the number you have used as your caller ID. You can make use of this information to ensure your E911 designation is being passed to the correct location and emergency service professionals.

988 - National Suicide Prevention Lifeline can be reached with this newly established three-digit dial plan. Officially, on July 16, 2022, all areas will be able to route calls to 988 to the National Suicide Prevention Lifeline and Mental Health Crisis Lifeline, or to local agencies (in some areas) regardless of location. Currently, it is in the rollout process but will be fully adopted by July 16, 2022. Until the transition is complete, 1-800-273-TALK should be used, and for veterans, please use 1-800-273-8255 and Press 1. This is an important rollout, and we are doing everything to make it readily available to anyone who needs it.

We continue to provide services that we will offer for use in the future as they arrive.
