Toll-free code

Is 855 a toll-free number? What an 855 call really is

Reviewed by Sujan ThapaliyaLast updated

What is area code 855?

855 is a toll-free area code in the North American Numbering Plan, in service since 2010. Calls to an 855 number are free for the caller; the business receiving the call pays. It is not tied to any city or state.
Where area code 855 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 855 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 855, but overlays have made ten-digit dialling the safe default. Dial 855 followed by the seven-digit number.
  2. 2

    From elsewhere in the US or Canada

    Dial 1, then 855, 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 855, then the seven-digit number. On a mobile, type + instead of the exit code: +1 855 followed by the number works from any country.

Background

About 855

855 is toll-free. It is heavily used by customer-service lines, which is why it shows up so often on caller ID, and why it is also imitated by scam callers.

Unwanted calls

Why you are getting 855 calls

The reason an unfamiliar 855 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 855 rather than receiving from it, the relevant reading is how toll-free numbers work — the same signals that decide whether a call from this code gets answered decide whether yours does.

Frequently asked questions

Where is area code 855?
855 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 855 a scam?
855 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 855 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 855 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.
