emergency_number

An emergency number, not a subscriber line

The input is the emergency number of its region (911, 112, 999), which connects to a service and never to a person, so it is not a subscriber number.

Free. Invalid numbers never cost a credit.

What it means

Emergency numbers are recognised from the short-number metadata of the country the request named, or the one the number itself identifies. They are answered by name rather than as too_short so a form can reject them with a clear message.

What to do

Reject it. Nothing about a person can be learned from an emergency number, and a system must never dial or text one.

Example response

{
    "valid": false,
    "reason": "emergency_number",
    "e164": null,
    "country": null,
    "risk_score": null
}

Abbreviated: a real answer carries all 33 fields, listed in the validate-phone reference.
