What is TFN?

Toll-Free numbers (TFN) are telephone numbers with distinct three-digit area codes that can be dialled from US and Canadian landlines with no charge to the caller. Toll-Free numbers begin with one of the following three-digit codes: 800, 888, 877, 866, 855, 844 or 833.

Toll-Free numbers are particularly common for customer-service calling. Toll-Free service has traditionally provided customers with a free and convenient way to contact businesses (wireless callers, however, will be charged for the airtime minutes used during a Toll-Free call unless they have an "unlimited calling" plan). Toll-Free numbers can also be text-enabled so businesses and customers can communicate via SMS and MMS messages.

Text-enabling a Toll-Free number won’t have any effect on your voice services on that number. Voice and messaging on a Toll-Free number run completely independently from one other; thus, you can enable voice via one provider and messaging via another provider, like Sinch. If you don’t have a Toll-Free number for your business yet, Sinch can set up a new one for you, and provide both voice and messaging services.

What are the additional costs related to TFN?

There is no cost to verify a Toll-Free number.
