Toll-free numbers are numbers that begin with one of the following three-digit codes: 800, 888, 877, or 866. Toll-free numbers allow callers to reach businesses and/or individuals without being charged for the call. The charge for using a toll-free number is paid by the called party (the toll-free subscriber) instead of the calling party. Toll-free numbers can be dialed directly to your business or personal telephone line.Toll-free numbers are very common and have proven successful for businesses, particularly in the areas of customer service and telemarketing. Toll-free service provides potential customers and others with a “free” and convenient way to contact businesses.Toll-free numbers are also increasingly popular for personal use. For example, parents can obtain toll-free numbers to give to a young adult who is away at college, allowing that young adult to call home anytime without having to make a collect call or pay for the call.
