Toll-Free Numbers (TFNs) can be called by anyone in the US without them incurring charges. These numbers begin with one of the following three-digit codes: 800, 888, 877, 866, 855, 844, or 833.  

Clickatell provides the ability to send and receive text messages from one or more toll-free telephone numbers. Recipients can respond to that message with a call or text.

Although 800, 888, 877, 866, 855, 844, and 833 are all toll-free codes, they are not interchangeable. 

TFNs are best suited to Application-to-Person (A2P) communications and are more affordable than US Short Codes.

Clickatell supports the following:

• Supply a brand-new Toll-Free Number for text messaging only.

• Text-enable an existing voice Toll-Free Number.

NOTE: Clickatell does not supply any voice capabilities.
