short_number

A short code or service number, not a subscriber line

The input is a valid short number for its region, such as a carrier service code (611) or a national helpline (101), rather than a number a person can be reached on.

What it means

Short codes are dialable but belong to services, carriers and campaigns; they have no subscriber, carrier or location in the sense the other fields describe. They are recognised only when a country is known, from the short-number metadata of that country.

What to do

Reject it for contact details. If you validate SMS short codes on purpose, the country and the value are all there is to store.

Example response

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

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