The seven toll-free codes, 800 to 833
All seven codes work exactly the same way and share one nationwide pool. The only real difference is age: when one code runs out of numbers, the FCC opens the next. Newer codes are cheaper and easier to register, so they attract more startups and, unfortunately, more scammers. Each code below links to its full guide.
When each code opened
822 is reserved as the next toll-free code but has never been placed in service. There are no working 822 numbers, so a call or text claiming to be from one is fake by definition. The later reservations 880 through 887 and 889 are not in service either.

Is this 8xx number a scam? Check it in 60 seconds
1. Don’t trust the caller ID
Spoofing software can display any 8xx number. The number on your screen is a claim, not a fact.
2. Hang up, then call the official number
If the caller claims to be your bank or a delivery service, find the company’s number on its website or your card and call that. Never call back the number that called you.
3. Never pay or verify by phone
No legitimate company asks for gift cards, wire transfers, or your full Social Security number on a call they placed to you.
4. Report and block
Forward scam texts to 7726 (SPAM). Report calls at reportfraud.ftc.gov, and block the number on your phone.
How toll-free numbers work
Toll-free means the business receiving the call pays for it, not you. Calls to toll-free numbers are free from U.S. landlines and mobiles, and the same number works from Canada and other North American Numbering Plan countries. From overseas, toll-free numbers generally don’t work or aren’t free. Numbers are assigned through registrars supervised by the FCC, first come, first served, which is why a toll-free number says nothing about where a company operates. Dialing is always the full ten digits, with 1 in front from a landline. Many businesses also enable text messaging on their toll-free numbers.
A single number gives customers nationwide one free way to reach you, with calls routed wherever you work. AT&T Business offers toll-free service for businesses of every size.
Toll-free codes FAQ
Are 800 numbers free to call?
Yes. Calls to any toll-free code (800, 833, 844, 855, 866, 877 or 888) are free from U.S. landlines and mobile phones. The business receiving the call pays for it. From outside the U.S. and Canada, toll-free numbers may not connect or may be billed as international calls.
What is the difference between 800, 833, 844, 855, 866, 877 and 888?
Nothing functional. All seven work identically and cover the same territory. They differ only in age: 800 opened in 1967 and each later code opened when the previous ones filled up, ending with 833 in 2017. Older codes tend to belong to established organizations because their numbers were claimed decades ago.
Is 822 a real area code?
No. 822 is reserved as the next toll-free code but has never been placed in service. There are no working 822 numbers, so any call or text that displays 822 is spoofed. The same goes for 880 through 887 and 889.
Why do scammers use toll-free numbers?
Because toll-free numbers look corporate and carry no location clues, a spoofed 8xx caller ID borrows the credibility of banks and government agencies. Newer codes like 833 and 844 are also cheap to register in bulk. Treat the caller ID as a claim, not a fact, and call the organization back on its official number.
Can I text a toll-free number?
Often, yes. Many businesses text-enable their toll-free numbers for order updates and support. But a text from a toll-free number you never contacted, especially one asking you to click a link or verify an account, follows the same scam playbook as a call: do not click, and report it by forwarding to 7726 (SPAM).
Where is a toll-free area code located?
Nowhere. Toll-free codes are non-geographic: an 8xx number says nothing about where the caller is. Any page or call that claims a toll-free number belongs to a specific city is wrong. Geographic area codes are covered in our area code directory.
How do I get a toll-free number for my business?
Toll-free numbers are assigned by FCC-regulated entities called RespOrgs through phone and communications providers. AT&T Business offers toll-free service with nationwide routing. Specific vanity numbers (like 1-800-FLOWERS) are first come, first served.
How do I block unwanted toll-free calls?
On AT&T wireless, the free ActiveArmor app blocks fraud calls at the network level and labels suspected spam. You can also silence unknown callers on iPhone and Android, and report unwanted calls to the FTC at ReportFraud.ftc.gov. Blocking one 8xx number has limited value because spoofers rotate numbers constantly.
Do toll-free numbers still matter now that most people have unlimited calling?
The free call matters less, but the number itself still works as a trust and memory signal, one number that works nationwide, often spelled as a word. That is why businesses keep registering them, and why 833 opened in 2017 after six earlier codes filled up.
Is a call from an 800 number safer than one from 833?
Slightly, in practice, but do not rely on it. 800 numbers were mostly claimed decades ago by established organizations, while 833 numbers are new and cheap. Spoofing erases the difference: a scammer can display any number. Verify the caller the same way regardless of the code.
