Product overview

Fraud Prevention products include the Fraud Prevention Registry (consortium-based fraud identification), Number Verification (silent MNO authentication), SIM Swap Detection (device change monitoring for ATO prevention), and KYC Matching (identity verification against MNO subscription data). All services are delivered via REST APIs for real-time, low-latency integration.

NetNumber partnerships and signals
Strategic signalPartnerships
Two partnerships are on record, tiered core.
- TMT IDcoreTMT ID and NetNumber formed a strategic partnership to advance mobile fraud prevention capabilities across global markets. The collaboration involves exchanging and integrating fraud signals into each company's respective solutions, combining TMT ID's global mobile fraud signals and digital identity intelligence with NetNumber's phone number intelligence and routing expertise. The partnership enriches existing offerings rather than replacing them, creating a more comprehensive fraud prevention ecosystem for enterprises, service providers, and platforms worldwide.
- TwoFivecoreNetNumber partnered with TwoFive, a Japan-based telecommunications solutions provider, to expand phone number intelligence services across Japan and Vietnam. TwoFive resells NetNumber's Carrier ID and Number Check services, providing local sales, support, and integration assistance to carriers, CPaaS providers, and enterprises in the region. This partnership enables regional organizations to improve call routing accuracy, enhance fraud prevention tactics, and optimize customer communications.

NetNumber competitors and assessment
Company assessmentBroad incumbents
- Sinch AB: Sinch is a global CPaaS leader built partly through acquisitions (including most of Inteliquent's messaging); its number lookup, verification, and routing capabilities overlap with NetNumber's Carrier ID and Number Check for messaging and voice customers worldwide.
- Bandwidth Inc. Bandwidth is a leading CPaaS and messaging platform that internally manages number intelligence and routing at scale; as a communications platform incumbent it overlaps with NetNumber in serving enterprise and carrier message-routing needs.
- IDEMIA: IDEMIA is a global identity and security vendor that provides SIM-based identity verification, KYC, and subscriber data products to MNOs, directly competing with NetNumber's Number Verification, KYC Matching, and SIM Swap Detection services.
- TransUnion (Neustar): TransUnion acquired Neustar's Numbering, Routing, and Number Registry assets and sells phone number intelligence alongside its broader credit and identity data business, directly competing with NetNumber in carrier-grade numbering intelligence at much larger scale.
Emerging players
- Plivo: Plivo is a CPaaS platform offering voice and SMS APIs to enterprises; while more developer-focused than NetNumber, it competes for messaging-and-voice customer budgets that often buy number intelligence alongside CPaaS tooling.
Regional players
- Hungarian Telephone Numbering Registry: The Hungarian numbering registry is one of many regional/national numbering authorities (alongside iconectiv for North America) that compete implicitly with NetNumber for authoritative routing data within their territories.
Direct peers
- Prove Identity: Prove (formerly Payfone) is a digital-identity vendor whose phone-based authentication, SIM swap, and KYC APIs compete directly with NetNumber's fraud prevention and identity portfolio for enterprise onboarding and ATO use cases.
- Telesign: Telesign provides phone number intelligence, SMS verification, SIM swap detection, and identity APIs serving the same enterprise and CPaaS customers as NetNumber; the two are the closest direct competitors in the phone-validation and digital-identity API space.
- TMT ID: TMT ID delivers mobile fraud signals and digital identity intelligence via APIs for telco and enterprise use cases; NetNumber now partners with TMT ID, but their catalogs of SIM swap, KYC, and fraud signals overlap directly, making them head-to-head competitors in many accounts.
- iconectiv: iconectiv (formerly Telcordia/Bell Labs) operates the authoritative LERG and TITAN routing databases used by North American carriers; it is the closest analogue to NetNumber's nnSR for numbering and routing registry services.
