      "answer": "Either: in the North American Numbering Plan the line type belongs to the exchange (the three digits after the area code), not to the area code. Of the 248 exchanges on record in 458, 72 (29%) were allocated as mobile, 33 (13%) as fixed line, 119 (48%) as VoIP and 24 (10%) have no line type on record. A number can have been ported since, to another carrier and even to another line type."

      "answer": "37 carriers hold exchanges in 458 on record; the most: Onvoy (48), T-Mobile (22) and Ton80 Communications (22). 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 458 phone number?",
      "answer": "In E.164 a 458 number matches ^\\+1458[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 (458) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP."
