Of the 196 exchanges on record in 854, 58 (30%) were allocated as mobile, 24 (12%) as fixed line, 100 (51%) as VoIP and 14 (7%) have no line type on record. A number can have been ported since, to another carrier and even to another line type."

      "answer": "35 carriers hold exchanges in 854 on record; the most: Onvoy (42), AT&T (25) and Fractel (16). These are the original allocations: with number portability, a number may be served by another carrier today, which only a live carrier lookup (an HLR or MNP query) can tell."
    },
    {
      "question": "How do I validate a 854 phone number?",
      "answer": "In E.164 a 854 number matches ^\\+1854[2-9]\\d{6}$: +1, the area code, a central office code that does not start with 0 or 1, then four digits. Written nationally it reads (854) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP."
