Tollfree

Tollfree refers to a telephone number or service arrangement designed so that the caller does not pay toll charges for the call. Instead, the recipient or the organization owning the number bears the cost. Toll-free numbers are commonly used by businesses, nonprofits, and government agencies to encourage customers to contact them without worrying about long-distance charges.

In North America, toll-free numbers are typically in the 800-series as part of the North American Numbering Plan. Common prefixes include 800, 888, 877, 866, 855, 844, and 833. Calls to these numbers generally do not incur charges for callers dialing from landlines, and increasingly from mobile phones, though some mobile operators or specific plans may apply charges in certain circumstances.

Internationally, many countries offer toll-free services with their own prefixes or codes. For example, the UK uses 0800 and 0808, while countries such as Australia use 1800. The availability and cost to the caller can vary by country, operator, and whether the call originates from a landline or a mobile network.

How toll-free numbers work: when a toll-free number is dialed, the call is routed through a toll-free service network to the recipient’s number, which may be a landline, mobile, or VoIP endpoint. The recipient typically pays for inbound calls through fees, subscriptions, or other arrangements with the service provider. Toll-free numbers may support features such as vanity dialing, call routing, IVR, and SMS in some regions.

Administration: in the United States and Canada, toll-free numbers are allocated within the NANPA framework and managed by a designated toll-free administrator. Numbers can generally be ported between providers, subject to policy and technical rules.
