Supported Three-Digit Dial Plans

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

977

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 the 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.

Any 911 calls through an account that has an E911 address on record assigned to a DID will be connected at no cost and will remain that way.

NOTE: A 911 request without an E911 address on an account DID will be billed $95 per instance (E911 Connection Fee) of each request. To avoid this charge a 911 call must be made from the account DID that has the assigned E911 profile. We highly recommend dialing 933 for testing purposes. 

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 currently have on record for the number you have used as your caller ID. You can make use of this information to ensure your E911 designation passes to the correct location and emergency service professionals.

988

The National Suicide Prevention Lifeline can be reached with this newly-established three-digit dial plan. Officially, 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. This is an important rollout, and it is it readily available to anyone who needs it.
