28 June 2005 06:26 (UTC)An N11 code or N11 number (said as "N-one-one") is a special abbreviated dialing telephone number within the North American Numbering Plan, which allows access to special services. Each of these eight numbers prevents 10,000 telephone numbers (from N11-0000 to N11-9999) from being used. Only non-geographic area codes, such as toll-free 800/888/877/866/855 numbers and 900 numbers may use N11 as the telephone exchange prefix, since the area code must always be dialed for these numbers.
