What Is a Trust Score and How Is It Calculated?

The Identity Score: Do These Details Belong Together?

The Identity Score establishes whether the details you were given are consistent with one another. It checks that the phone number is real and in service, that the email address exists and has history, and that the name and address appear together in identity records rather than in isolation. A high Identity Score means the details corroborate each other across independent sources. A low one means they do not — which can indicate a fabricated persona, or simply someone who recently moved and changed numbers. The score reports the discrepancy; it does not interpret the motive.

Key Signals Behind the Score

Phone and Carrier Records

TrustMatch checks a number against carrier records: whether it is a working line, what type of line it is, and how long it has been associated with the name given. A number that has stayed with a major carrier for years is harder to obtain anonymously than a prepaid or internet-based line activated last week. Line type and tenure are facts about the number, not about its owner — plenty of legitimate people use internet-based numbers, so this signal contributes to a score rather than deciding one.

Email Validity and Age

For an email address, TrustMatch checks whether the address actually exists, how long it and its domain have been in use, and whether it belongs to the same identity as the other details you submitted. A long-standing address that resolves to the same person as the phone and name corroborates the rest of the picture. A newly registered address that connects to nothing else does not. TrustMatch does not search breach databases or the dark web, and a TrustCheck will never tell you whether an address has been exposed in a leak.

Name and Address Consistency

TrustMatch checks whether the name and address you provide are linked to the same identity in identity registries and commercially available digital-footprint data. A name that has appeared at an address over a period of years, tied to the same phone and email, strongly corroborates that identity. Bear in mind that addresses are evaluated independently of one another: submitting several does not mean the check treats one as the person's current home and the rest as history.

Transaction Risk

TrustMatch also receives a commerce-derived risk indicator. It reflects patterns in commercial and transaction data associated with the identity — nothing more. It is not a measure of character, criminality or honesty, and TrustMatch deliberately surfaces it as "transaction risk" rather than as a safety rating, because reading it as one would be a misuse of what it measures.

What a Trust Score Cannot Tell You

A TrustCheck verifies details, not people. It cannot tell you whether someone is honest, whether they intend to defraud you, or whether they are dangerous. It does not read criminal records, sanctions lists or watchlists. It does not analyse photos, video or voice, perform liveness or biometric checks, collect device fingerprints, or examine anyone's messages or browsing. It is not a background check and must not be used to make decisions about employment, housing, credit or insurance. A person with a perfectly consistent identity can still be a scammer — what a high score tells you is that they are probably using their own name.

Comparing Identity Verification Methods

Feature	TrustMatch Identity & Trust Score	Traditional KYC (Know Your Customer)	Simple Email/Phone Verification	Social Media Profile Check
Core Purpose	Tests whether a set of identity details describes one real, consistent person.	Regulatory compliance; identity verification against official documents.	Confirming ownership or active status of one contact method.	Surface-level reputation check of a public persona.
Data Sources	Phone carrier records, email validity and age, identity registries, digital-footprint data, a commerce-derived risk indicator.	Government ID, utility bills, document and facial checks.	SMS code, email link, domain check.	Public posts, follower counts, shared connections.
What It Detects	Details that do not belong together, and identities with little or no history behind them.	Forged or altered identity documents.	Disposable addresses and temporary numbers, when they fail outright.	Very little; profiles are easy to fabricate.
When It Runs	Point-in-time. A TrustCheck is a snapshot; nothing is monitored afterwards.	Typically once, at onboarding.	At the moment of verification only.	Manual, whenever someone looks.
What It Cannot Do	Judge character or intent; read criminal, credit or sanctions records; analyse photos, video or devices.	Catch a real person using genuine documents for fraud.	Say anything about who owns the contact method.	Verify any underlying identity.

How TrustMatch Calculates Your Combined Trust Score, Step by Step

A TrustCheck runs in one pass and returns a score, a verdict and the individual signals behind them. Seeing the steps makes clear both how the number is produced and how narrow its inputs are. The Federal Trade Commission reported that consumers lost more than $12.5 billion to fraud in 2024, and a large share of those losses began with someone misrepresenting who they were — which is exactly the claim this check tests.

1. Data input. You submit a name plus at least one other detail — a phone number, an email address, or an address. A name on its own tells you that the name exists, not whose it is, so the check is far more useful with a second detail to cross-reference.
2. Identity Score calculation. Each submitted value is checked against identity records independently, and then against the others. The system looks for whether the details resolve to a single identity and how long that association has existed. Values that match nothing, or that resolve to different people, lower the score.
3. Trust Score assessment. The system weighs how well established the identity is: the tenure and line type of the phone, the age and validity of the email, the depth of the record behind the name and address, and the commerce-derived transaction-risk indicator. Thin or brand-new records lower this score.
4. Combined score and verdict. The two components are weighted into a single 0–100 score and a plain-language verdict, presented with the individual signals that produced them — so you can see which detail failed, not just that something did.

Used for what it measures, a TrustCheck is a fast way to find out that the person asking you for money gave you a phone number registered last week to a different name. Used as a verdict on a human being, it is the wrong tool. The score tells you how much the record supports someone's claim about their identity. Everything after that — whether to trust them — is still your call.
