Prefix list and billing rules per the FCC.
A toll-free number is a business phone number the caller is not charged for reaching. The cost of the call is billed to you, the business, instead of the person dialling.
In the US and Canada, toll-free numbers use one of seven prefixes: 800, 888, 877, 866, 855, 844 and 833. They are functionally identical. An 800 number is not better connected than an 833 number — it is simply older, so most 800 numbers were taken decades ago.
Toll-free is free from a landline, but a mobile caller still uses their own airtime minutes unless they are on an unlimited plan. It costs them nothing extra, but it is not literally free on a phone.
Their carrier sees a toll-free prefix and knows not to bill them.
A shared national database says who the number belongs to and where calls go.
A queue, an IVR, a team or a single agent — anywhere your people are.
The call arrives with the caller's details and history attached.
Because step 3 is just a setting, you can change where a toll-free number rings without changing the number.
| Prefix | Availability today |
|---|---|
| 800 | The original. Almost entirely allocated, so availability is rare. |
| 888, 877, 866 | Long established and widely recognised. |
| 855, 844 | Newer, with better availability for specific number patterns. |
| 833 | The newest US toll-free prefix and the easiest to get a clean number on. |
Whichever has the number you want. All seven work identically for the caller, so choose on availability rather than prestige.
Yes — 833 is a legitimate toll-free prefix, assigned and regulated exactly like 800. But an individual call from an 833 number can still be a scam, because the prefix says nothing about who is dialling it.
Do not act on anything the caller asks for while you are still on the call. Hang up, then dial the number printed on the company's own website or on the back of your card.

Pick from what is available, or search for a specific pattern.
Toll-free numbers come from one shared national pool, first come, first served — so the number you want may already belong to someone else.
In the US you cannot claim a toll-free number directly. It is reserved through a Responsible Organization, or RespOrg, which holds the record for you. Your provider handles this.
Assign it to a queue, an IVR or a team. This is a setting, so you can change it later without changing the number.
Call it from outside your own network — once from a landline and once from a mobile — and check it reaches the right queue and that any recording announcement plays. Only then put it on your website, your invoices and your ads. A toll-free number is cheap to buy and expensive to change once it is printed.
US toll-free numbers are provisioned in minutes, on any plan including the free one. Porting a toll-free number you already own runs to an agreed cutover window instead, so plan that one around a quiet day.
A vanity number spells a word or name, like 1-800-FLOWERS. It is an ordinary toll-free number with a memorable digit pattern.
Most obvious words on the 800 prefix went decades ago. A newer prefix like 833 is where availability is, and the number works exactly the same.
Federal rules prohibit acquiring more toll-free numbers than you intend to use, and ban selling one for a fee. You cannot reserve a stack of vanity numbers as assets, or buy one from a broker. 47 CFR § 52.107 — Hoarding
The rule also treats routing many toll-free numbers to one subscriber as evidence of hoarding, so keep the numbers you hold tied to lines you actually answer.
An international toll-free number is a number that customers in another country can call without being charged, with the cost billed to your business instead.
Toll-free numbering is national, not global. Each country runs its own toll-free ranges under its own regulator, and a number that is free to dial in one country is usually unreachable from outside it. So "international toll-free" means one of two quite different things.
You hold a separate toll-free number in each market you sell into, and publish the local one on each market's page. Customers dial a number that looks normal to them and costs them nothing.
This is what most businesses mean, and what most need. It is cheaper, faster to set up, and each country's number can route to a different team.

A Universal International Freephone Number, or UIFN, is one number that works across participating countries. It uses country code +800 followed by an eight-digit subscriber number, so eleven digits in total.
It is issued only to businesses using it in two or more countries, and it has to be live in at least two within 180 days of reservation or the reservation is cancelled. Not every country participates, so it rarely replaces in-country numbers entirely.
UIFN rules, ITU-T Recommendations E.152 and E.169.1If you are supporting customers in three or four markets, take a toll-free number in each. A UIFN is worth the extra work only when one printed number has to appear on packaging or contracts used worldwide.
Yes. Toll-free numbers in the US and Canada can send and receive SMS, but no toll-free number is textable by default. It has to be text-enabled and pass toll-free verification before carriers will deliver its messages.
Toll-free verification is a different process from 10DLC. 10DLC registers brands and campaigns for ordinary ten-digit local numbers through The Campaign Registry, whose own scope is 10DLC only. Toll-free numbers do not use it; they run their own verification with the messaging carriers. Registering one does not cover the other.
Unverified toll-free traffic is filtered or blocked rather than bounced with a clear error, which is why "our texts just stopped arriving" is usually a verification problem rather than a carrier outage.
New toll-free verifications now have to include a business registration number such as an EIN, the country the business is registered in, and an entity type, bringing toll-free into line with the scrutiny 10DLC already applied. Numbers verified before that date are not affected.
Practical effect: a sole trader without a registration number now has a harder time text-enabling a toll-free number than they did last year.
| Toll-free number | Local number | |
|---|---|---|
| Best for | Inbound support and sales lines | Outbound calling, regional presence |
| Who pays | You | The caller, at standard rates |
| Signals | An established, national business | You are nearby |
| Outbound pickup | Lower — an unfamiliar national number | Higher — a familiar area code |
Use a toll-free number for the calls you want to receive and a local number for the calls you make. Most teams hold both on the same account.
Local phone numbersYou pay for the number, and you pay for the inbound minutes your callers use. A successful toll-free line costs more than an unsuccessful one.
HyperDial bills numbers at cost on every plan, including the free Base plan. Seats start at $19 per user a month.
Full pricingToll-free numbers are portable by regulation, so no provider can hold your number hostage. Porting to HyperDial is free, and your number keeps working while the transfer completes.
Not permanently, from anyone. Someone has to pay for a toll-free call, and by design that someone is the business.
Start on the free plan, pick a toll-free number, and point it at your support queue. Numbers are billed at cost, so there is no markup to negotiate.
Yes. 833 is a genuine toll-free prefix, assigned and regulated the same way as 800, 888 and 877, and it is non-geographic — it tells you nothing about where the caller is. But an individual call from an 833 number can still be a scam: caller ID can be spoofed, so what you see on screen is not verified identity. Judge the call by what is being asked for, not the prefix. If an unexpected 833 number asks for payment, passwords or personal details, hang up and dial the number on the company’s own website.
Not permanently, from any provider. Someone has to pay for a toll-free call and by design that is the business. What can be free is the plan, the porting and the setup: HyperDial bills numbers at cost with no markup on every plan including the free one, but the number and the inbound minutes are still real costs.
Toll-free numbers in the US and Canada can send and receive SMS, but only after being text-enabled and passing toll-free verification — a separate process from the 10DLC registration used for ordinary local numbers. Since 1 January 2026, new toll-free verifications also require a business registration number, the country of registration and an entity type.
A number customers in another country can call without being charged. Toll-free ranges are national, so a US 800 number is not free to dial from abroad. You either hold a separate toll-free number in each market, which is what most businesses do, or use a Universal International Freephone Number on country code +800, which works across participating countries but must be live in at least two of them.
You do. The caller pays nothing from a landline. From a mobile, the call uses the caller’s own airtime minutes unless they are on an unlimited plan, but they are not billed for the call itself.
No. All seven prefixes work identically for the caller. 800 is simply the oldest, which is why almost none are available.
You pay for the number and for the inbound minutes your callers use. HyperDial bills numbers at cost with no markup; minute rates vary by country.
Yes. Toll-free numbers are portable by regulation, and porting to HyperDial is free. Your number keeps working while the transfer completes.
No. Federal rules prohibit acquiring more toll-free numbers than you intend to use and ban selling one for a fee, so a vanity number cannot legitimately be bought as an asset. Numbers come from a shared national pool, first come, first served.
Usually not. An unfamiliar national number is answered less often than a local one. Use toll-free for inbound and local numbers for outbound.
