Toll-free code

Is 877 a toll-free number? What an 877 call really is

Reviewed by Sujan ThapaliyaLast updated

What is area code 877?

877 is a toll-free area code in the North American Numbering Plan, in service since 1998. Calls to an 877 number are free for the caller; the business receiving the call pays. It is not tied to any city or state.
Where area code 877 sits in a North American number: the three-digit area code, then the three-digit exchange code, then the four-digit line number, all under country code 1. The diagram also shows the two validity rules — an area code never starts with 0 or 1, and a repeated middle digit marks a service code such as 800 for toll-free rather than a place.
The 1 you dial before a ten-digit number is a long-distance prefix, not part of the number itself.

Step by step

How to call an 877 number

The same ten digits, dialled three different ways depending on where you are calling from.

  1. 1

    Within the same area code

    Many carriers still allow seven digits inside 877, but overlays have made ten-digit dialling the safe default. Dial 877 followed by the seven-digit number.
  2. 2

    From elsewhere in the US or Canada

    Dial 1, then 877, then the seven-digit number — eleven digits in total. The leading 1 is the North American long-distance prefix, not part of the number.
  3. 3

    From outside North America

    Dial your country's exit code, then 1 for the North American Numbering Plan, then 877, then the seven-digit number. On a mobile, type + instead of the exit code: +1 877 followed by the number works from any country.

Background

About 877

877 is toll-free and long established, old enough that most consumers recognise it as legitimate.

Unwanted calls

Why you are getting 877 calls

The reason an unfamiliar 877 number keeps calling is usually neighbour spoofing: automated systems fake a caller ID in the recipient’s own area code because a local-looking number is answered far more often than an unfamiliar one. The number displayed is frequently not the number placing the call, and may belong to someone with no idea it is being used.

What actually helps:

  • Let unknown numbers go to voicemail. Automated diallers rarely leave a message; a real caller will.
  • Do not press any key to be removed. On an automated call, a keypress confirms a live human and increases the volume you get.
  • Register on the national Do Not Call list and report unwanted calls. It does not stop fraud, but it does constrain legitimate telemarketers.
  • Turn on your carrier’s call-filtering service. Filtering now uses STIR/SHAKEN attestation, which is why properly signed business calls get through and spoofed ones increasingly do not.

If you are calling into 877 rather than receiving from it, the relevant reading is getting a toll-free number — the same signals that decide whether a call from this code gets answered decide whether yours does.

Frequently asked questions

Where is area code 877?
877 is not tied to a location. It is a toll-free code used nationwide across the United States, Canada, and the Caribbean territories in the North American Numbering Plan.
Is a call from 877 a scam?
877 is a legitimate toll-free code used by many real businesses. It is also imitated by scam callers, precisely because a toll-free number looks official. Never give card details or verification codes to someone who called you; hang up and dial the number printed on your statement or the company's website.
How do I find out who owns an 877 number?
Toll-free numbers are registered in a shared national database, but subscriber details are not publicly searchable. Practical options: search the full number online, since businesses publish theirs; check whether the number appears on a bill or statement you hold; or call it back from a number you do not mind sharing and see who answers.
Is 877 free to call from a mobile?
Yes, within the country. Toll-free calls are free to the caller from US and Canadian phones. Calling a North American toll-free number from outside the region is usually not free, and often will not connect at all.
