"800 number" meaning in English

{
  "etymology_text": "In the original North American Numbering Plan, phone numbers beginning with an area code of \"800\" were reserved for so called toll-free numbers, where the party receiving the call pays the charges. As more toll-free numbers were needed, additional area codes were added to the scheme including 888, 877, 866, 855, 844, 833 and one more was reserved: 822. The term \"800 number\" is used colloquially to refer to all of these.",
