Discover how GSMA Open Gateway and CAMARA’s Number Verification 2.0 move beyond OTP-based authentication to network-based identity verification, helping enterprises reduce fraud and improve secure digital authentication.
For more than a decade, the mobile number has quietly become a core signal of digital identity. Banks, fintech companies, e-commerce platforms and even government services have relied on a simple belief: if a user can receive a message or code on a phone number, that user must be genuine. Even while logging into websites or portals, the system has no reliable way to determine whether it is engaging with a real human or an automated agent.
Enterprises today are dealing with a very different digital security reality. Fraud is growing faster than digital adoption. OTPs are intercepted, SIMs are swapped, codes on calls are forwarded and malware routinely bypasses app-level controls. At the same time, customers are losing patience with multi-factor authentication — OTP delivery delays, lost SMS codes and broken login journeys create a difficult compromise between security and user experience that most organizations are struggling to resolve.
This is where a fundamental shift is taking shape. Digital identity is no longer about receiving an OTP and typing it in. It is about confirming that the user is present on the network. Number Verification 2.0 enables this new way of mobile identity verification, confirming that a user’s mobile number and device are actively present on the network.
Why Traditional OTP-Based Authentication Is Falling Behind Modern Fraud Techniques
Mobile numbers became digital identity by default. OTPs were easy to deploy, universally understood and effective. But over time, their weaknesses have become unavoidable:
· OTPs only prove message delivery, not real user authenticity
· SIM swap attacks bypass OTPs entirely
· SMS-based verification adds friction and cost
· Failure rates rise during peak traffic or roaming
· OTP delays and drops remain a persistent, unresolved problem
In other words, enterprises have been authenticating channels, not users. As digital transactions scale and fraud becomes more sophisticated, that model is no longer sustainable.
The Shift: From OTP-Based Authentication to Network-Based Identity Verification
CAMARA’s Number Verification 2.0 marks a clear shift from how mobile numbers have been verified until now. Instead of asking “Can I reach this number?”, NV 2.0 asks a far more powerful question:
“Is the real user, on the real device, actively present on the mobile network right now — accessing a particular application?”
Verification no longer depends on sending OTPs or prompting users with codes. Instead, it relies on network API authentication powered by real-time mobile network signals.
It happens inside the mobile network, leveraging real-time signals. The result is a deterministic, low-latency trust signal — delivered via Number Verification APIs — that enterprises can use instantly in their authentication and risk engines. This is identity without friction. Security without user intervention.
What Number Verification 2.0 Enables for Enterprises
The real power of NV 2.0 lies in the business use cases it directly enables:
OTP-less login and authentication at scale. Authentication completes in the background, removing the step that causes the most drop-off in login and onboarding flows.
Stronger Fraud Prevention Where It Matters Most. Network-confirmed presence is significantly harder to spoof than an intercepted OTP, making NV 2.0 directly applicable to transaction authorization and account takeover prevention.
Faster Onboarding and Account Recovery. Identity verification that previously required multiple steps and user action can now be completed through a single, low-latency API call.
Works on Mobile Network as Well as Wi-Fi. Unlike SMS-dependent methods, NV 2.0 functions reliably across both network types, eliminating delivery failures caused by connectivity conditions.
NV 2.0 reshapes digital journeys — not by adding security layers on top of existing flows, but by replacing the weakest link in those flows.
Why Number Verification 2.0 Matters for Telcos
For mobile operators, Number Verification 2.0 represents something even bigger. For years, networks have been the most trusted layer in the digital ecosystem, but that trust was never directly monetized. NV 2.0 changes that.
By exposing network-verified identity signals through GSMA Open Gateway APIs and standardized network APIs, telcos move up the value chain.
· From connectivity providers to trust providers
· From infrastructure to enterprise-grade platforms
· From volume-driven revenue to high-margin digital services
Importantly, NV 2.0 is often the first network API that enterprises adopt. It solves a real and immediate problem. Once integrated, it opens the door to a broader portfolio of network-powered capabilities.
How Number Verification 2.0 Improves Digital Authentication and User Experience
From a customer’s perspective, Number Verification 2.0 removes unnecessary friction from critical digital journeys. Login, transaction authorization and account recovery happen seamlessly, without waiting for OTPs or switching between apps. Authentication becomes faster and more consistent, even during peak traffic or roaming scenarios. Users experience stronger security without additional effort — reinforcing trust while preserving the speed and simplicity expected from modern banking and financial platforms.
Number Verification 2.0: The Foundation of Network-Based Identity Verification
Number Verification 2.0 is not an isolated innovation. It is the foundation of a larger transformation.
As networks open up securely and consistently across markets, enterprises gain access to identity signals that were previously fragmented or unavailable — device trust, SIM integrity, real-time presence and more. Together, these signals are shaping a future where digital trust is built into the network, not bolted onto applications.
This is the emergence of network-based identity as a service.
The Road Ahead
For enterprises, Number Verification 2.0 offers a practical path to reduce fraud, remove authentication friction and improve user experience without changing user behaviour.
For mobile operators, it represents a tangible opportunity to monetize network trust through scalable, standards-aligned APIs and deepen engagement with enterprise customers. If you are exploring how CAMARA compliant and GSMA certified network-based identity can fit into your digital strategy — now is the time to start that conversation. Whether you are evaluating use cases, designing authentication flows or planning your Network API roadmap, understanding how Number Verification 2.0 applies to real-world journeys is the first step.
