This comparison is written for business and wholesale buyers choosing inbound numbers for phone systems, contact centres and platforms — not for consumers picking a second-line app. Both toll-free and local numbers are virtual numbers (public phone numbers provisioned online rather than tied to a physical line), and both are DID (Direct Inward Dialing — a number routed directly into your phone system) numbers delivered over SIP (Session Initiation Protocol, the signalling standard for internet calls).
Because the technology underneath is the same, the real decision is not toll-free versus local as products — it is which number type fits the job. If the underlying terms are new to you, start with DID vs virtual numbers. This page focuses on the practical trade-off: who bears the call cost, how callers perceive each type, and how far each one reaches.

Are toll-free and local numbers different products?
No. Both are virtual DID numbers delivered over SIP, so the underlying product is identical; they differ only by number type. A type sets the dialling prefix, who bears the call cost, and where the number can be dialled from. Once you see them as variants of the same DID number rather than separate products, the choice becomes a matter of matching the type to your callers and your budget rather than picking a different technology.
What is a local number?
A local number is a local/geographic number — one that carries the dialling prefix of a specific city or region. To a customer in that area it reads as local, like a neighbour rather than a distant call centre, which tends to lift answer rates on outbound calls and reassures inbound callers. Local numbers are the most widely available type across countries, and the caller pays their normal local or standard rate. For establishing presence in a market and improving the odds that a call gets answered, the local number is usually the default choice.
What is a toll-free number?
A toll-free number is free to the caller — the number holder bears the cost of inbound calls instead of the person dialling. Publishing a toll-free line signals that contacting you costs the customer nothing, which can lift volume for support and sales in markets where the format is well recognised. Toll-free numbers give national reach within a country, so one line serves callers countrywide. The trade-off is that you carry the call cost, so they suit lines where removing the caller's cost is worth paying for — and, as covered below, they are often restricted to in-country dialling.
Where do national numbers fit?
A national/non-geographic number represents a whole country without pinning you to a single city. It sits between local and toll-free: it gives one countrywide identity like a toll-free line, but the caller usually pays a standard national rate rather than nothing, and it does not carry the "free to call" signal. National numbers suit a single brand line that should feel countrywide rather than tied to one location, and they are a sensible middle option when a city identity is too narrow but you do not want to bear the caller's cost.
