The United States and its territories, Canada, and a number of Caribbean countries are all covered by area code 844. The area code is part of the North American Numbering Plan, an integrated telephone-numbering system in which participating nations pool numbering resources.
In a number of countries covered by the NANP, area code 844 is used for toll-free numbers. Toll-free numbers allow callers to contact persons and businesses without being charged, and the toll-free subscriber covers the cost of utilising the number. The NANP also covers the area codes 800, 855, 866, 877, and 888.
