Porting and SIM swap are both routine and both a reason to trust a number less right now, and a check built only to confirm the number is real answers neither.
Not "is this a valid number". It is has this number been ported, swapped, or breached recently, because each is a reason today's answer differs from last week's.
Number intelligence covering line type, porting history, recent SIM swap, and known exposure in breach data. Used as an identification signal inside KYC and as a standalone risk signal inside Risk Intelligence, one canonical check either way.
Not established for a public claim. Market and carrier coverage need a source before this section states a figure.

Which signals block, step up, or are logged only, set per market and per use case.
A number ported an hour ago still passes a check that only confirms it is real, and that is exactly when SIM-swap fraud happens.
The individual factors, not a combined score with no way to see inside it.
Written once, used from both programs. A change to the underlying data reaches every place phone risk is checked instead of drifting between two integrations that started identical and stopped being identical.
