An 800 number for your business

800 is the original US toll-free code. True 1-800 numbers are scarce, so we check what is free for you, or set you up on 833 to 888, which work the same for callers.

Free for 7 days. No card, keep your number.

What an 800 number is

800 is the original toll-free code, in use since 1967. As demand grew, six more codes opened beside it, from 888 in 1996 to 833 in 2017. It is also the code behind the most famous vanity number of all, 1-800-FLOWERS.

Free for the caller

A call from a landline costs the caller nothing. Your business pays for it. Mobile callers use their plan minutes unless the plan is unlimited.

A toll-free code since 1967

800 became a toll-free code in 1967, according to Somos, the administrator of the US toll-free number database.

Same rules as every code

800, 833, 844, 855, 866, 877 and 888 all work the same way. They are not interchangeable: 1-800-555-0100 and 1-888-555-0100 reach two different businesses.

On the Business plan

True 1-800 numbers are very limited and cost more. Ask us and we check, or take 833 to 888, which callers dial the same way.

Every toll-free code

All seven work the same way for callers, and all of them are on Allo. What differs is when each one opened. Pick one to read about it.

800 numbers, answered

800 is not a place. It is one of the seven US toll-free codes (800, 833, 844, 855, 866, 877 and 888), in use since 1967. A business on an 800 number can be reached from anywhere in the country, and the caller pays nothing from a landline.

From a landline, yes: the business receiving the call pays for it. From a mobile phone, the call uses the caller's plan minutes unless the plan is unlimited.

The code says nothing about who is calling. 800 numbers are ordinary toll-free lines that businesses use for sales and support. Like any number, one can be misused, so if a call looks wrong, call the business back on a number you already trust.

Toll-free numbers come with the Business plan. True 1-800 numbers are very limited and significantly more expensive, so ask our team and we check what is free. Most teams pick 833, 844, 855, 866, 877 or 888, which work the same for callers.

Yes. Allo ports toll-free numbers on 800, 833, 844, 855, 866, 877 and 888, for free. A toll-free port usually takes 7 to 14 business days, and the old line keeps taking calls until it completes.

On Allo, toll-free lines are for calls. To text customers in the US, add a local number registered for 10DLC, a one-time $24 for the whole company.
