Telecoms Fraud in Asia: Why Number Information Services Are the Not-So-Secret Weapon in Restoring Trust in Telecoms

Telecoms fraud across Asia has grown into a sophisticated, fast-moving ecosystem.

For operators and enterprises, the pressure is no longer just about stopping suspicious traffic: it is about making smarter, faster, more-informed decisions based on the available trusted data.

As the industry comes together at telecom events across the region this year – including CommuniCasia and MWC Shanghai -  one thing is clear: understanding the data behind a phone number is becoming central to tackling fraud effectively.

A Changing Fraud Landscape

Asia is both a major source and target of telecoms fraud. Increasing levels of mobile use, expanding mobile ecosystems and diverse regulatory environments have created opportunities for fraudsters to operate at a larger scale.

Common threats include impersonation scams delivered over voice and messaging, artificially inflated traffic (AIT), number spoofing and SIM-based fraud.

While these may appear different on the surface, they share a common dependency – they rely on a lack of visibility into number data.

When networks cannot confidently verify a number’s status, ownership or history, fraudsters gain the advantage.

The Scale Behind the Challenge

The growth of telecoms fraud in Asia mirrors the scale and pace of the region’s digital progress.

Asia Pacific is now home to more than 1.5 billion mobile network users, with connectivity continuing to expand rapidly across both developed and emerging markets; with GSMA projecting this to reach 1.8 billion users by 2030.

At the same time, 5G adoption is accelerating, already accounting for a significant share of mobile subscriptions and set to become the dominant technology in the coming years.  Currently, more than four in ten mobile broadband subscriptions are already 5G.

Messaging channels alone are seeing trillions of interactions globally each year, while voice and authentication services remain critical touchpoints for both operators and enterprises.

This growth brings opportunity, but also risk.

At the same time, the financial impact is significant. Industry estimates suggest that telecoms fraud costs tens of billions of dollars globally each year. Much of this activity is enabled through voice and messaging channels, where trust in the phone number remains a key vulnerability.

Across a region as vast and interconnected as Asia, cross-border traffic introduces further complexity. With varying numbering plans and regulatory requirements across markets, the ability to accurately understand and validate number data is no longer a “nice to have”, it is essential.

The Growing Importance of Number Information Services (NIS)

Traditional fraud controls still play an important role, but they are increasingly reactive in a landscape where numbers are constantly changing. Portability, reassignment and the use of virtual numbers have made it harder to rely on static data or simple rules.

This is where number information services are making a measurable difference.

By providing real-time insight into numbering data, operators and enterprises can better understand:

• Whether a number is valid and active
• Which network it belongs to
• Whether it has recently ported, how many times and to who
• If it indicates markers associated with higher risk or inconsistent behaviours

With this level of available information, decisions can be made with greater confidence and often before a call is connected or a message is delivered.

 

Strengthening Defences Across Key Fraud Areas

A more informed view of Number Information Services (NIS) data allows organisations to address some of the most persistent fraud.

Impersonation and spoofing scams continue to undermine trust in voice communications. When a call appears to come from a trusted source, customers are far more likely to engage. Real-time number validation and CLI verification help confirm whether a number is genuinely assigned, reachable and consistent with its origin. Traffic-related fraud, including artificially inflated traffic (AIT), also remains a concern.

Validating numbers before sending messages not only improves security but also enhances delivery rates and reduces unnecessary costs, helping to build trust across communication channels.

 

From Insight to Action

The real value of number intelligence lies in how it is used.

Whether it is supporting fraud management, optimising operational processes or strengthening customer authentication, number intelligence is moving from a supporting role to a core resource.

This shift reflects a broader change in approach: from reacting to fraud after it happens, to preventing it through better information at the point of interaction.  Pro-active; not reactive.

 

A More Connected Approach to Fraud Prevention

Telecoms fraud in Asia is not confined by borders, technologies or individual organisations. It is a shared challenge that requires a more connected response.

Improving visibility into numbering data is one of the ways to strengthen that response. It helps operators protect their networks, enables enterprises to engage customers more securely and supports a more trusted communications ecosystem overall.

As conversations continue across the region’s telecom events, the focus is increasingly on practical solutions that deliver real impact. The industry is aligning around the use of trusted, real-time data to validate, route and secure communications more effectively.

Providers such as XConnect are supporting this shift by delivering number intelligence that helps operators and enterprises make more informed decisions, without adding complexity to existing systems.
