Fraud Number Intelligence

Know which numbers to trust before they enter your business and affect revenue or customer experience, with disposable number and traffic fraud data together in one check.

Know the risk behind any number

GSMA Fraud Number Intelligence is a single, API-based service that brings two layers of data together, so your team has the intelligence to block number fraud before it does any damage:

Disposable Number Intelligence – intelligence on temporary, rented and disposable numbers offered for one-time verification, account creation and other account-related activity.
IRSF/Traffic Fraud Intelligence – intelligence on premium-rate and revenue-share number ranges associated with IRSF, AIT, call pumping and other forms of artificial traffic inflation..

Where a number matches more than one risk type, classifications are returned independently, so your team can act without ambiguity.

Why is this important for your business?

Fast-moving number fraud creates cost, complexity and operational pressure for your business. GSMA Fraud Number Intelligence gives your teams the intelligence to get ahead of it.

Protect your revenue

Identify high-risk premium-rate numbers, fraud ranges and artificial traffic patterns earlier, so revenue share fraud and inflated messaging costs are stopped before they escalate.

Strengthen onboarding and verification

Detect disposable and high-risk numbers used to create fake accounts, exploit OTP flows or bypass verification — before trust is extended to the wrong user.

Decide with confidence

Enable your fraud and security team to turn risk signals into clear ‘allow, challenge or block’ decisions, protecting genuine customers while stopping bad actors.

Stay ahead with real-time intelligence

Benefit from data that is continuously refreshed, giving fraud, risk and verification teams a consistent view of number risk across markets and partners.

Practical examples of what it can do

Built for platforms that rely on phone-verified trust, across three core segments.

MNOs and MVNOs

Act faster on call and SMS fraud with real-time risk intelligence that supports your fraud prevention routing, blocking and investigation decisions.
When suspicious traffic spikes on a high-risk premium-rate range, check the risk in real time and act before costs escalate.
Maintain customer trust by reducing fraud impact while minimising disruption for genuine users.

Communications Platform as a Service (CPaaS)

Flag repeated OTP requests to disposable or high-risk numbers before messages are sent, helping reduce wasted verification spend.
Reduce trial abuse, account-sharing workarounds and geo-restriction bypass linked to temporary number use.
Embed trusted number intelligence into verification workflows to improve risk scoring and OTP decisioning.

Fintech, financial services and crypto exchanges

Add number-risk intelligence to signup, KYC, login and account recovery checks.
Flag disposable or suspicious numbers that may be used to bypass controls or re-enter services under a new identity.
If a signup or account recovery attempt uses a disposable number, the risk signal can trigger stronger verification before the account is opened, recovered or trusted.

Know which numbers to trust — before you act

GSMA Fraud Number Intelligence turns trusted, API-based number intelligence into the allow, challenge and block decisions that stay yours to make. Evaluate it against your own flows and see what it surfaces.
