The area code 855 is not used in any city. It’s a toll-free area code that’s utilised all over the US and Canada. Because the receiving party pays the long distance expenses, the calls are free to the caller.
While toll-free area codes like 855 are utilised in both the United States and Canada, the toll-free number’s owner may have limits on which calls are accepted. For example, if a company in the United States refuses to pay the rates for calls to Canada, it will ban Canadian phone numbers from connecting. Outside of North America, calls to 855 and other toll-free area numbers are not free.
