# What is Toll-free number?

A toll-free number is a phone number the person calling does not pay for; the receiving party does.

In the North American Numbering Plan they begin with 800, 833, 844, 855, 866, 877 or 888, and they have no geographic area. They identify a business line, not a place.

A toll-free number is a poor target for text messages unless the owner has enabled messaging on it, and it should never be validated as a personal mobile number.

Route toll-free numbers by what you plan to do with them. A call to one can be forwarded to any ordinary line, so the number says nothing about where the business sits. When you screen a lead list, tag these numbers as business lines, and look for a direct or mobile number at the same company if you need to reach a person by text.
