The GLF's Code of Conduct

The GLF's Work in Fraud

In today's hyper-connected world, fraudulent traffic is an ever-looming threat, casting close to a US$40 billion shadow over the telecoms industry. This jeopardises the sustainability of reliable telecommunications services, making it a pressing concern for all stakeholders.

To drive collective action against fraud, the GLF introduced its Code of Conduct for Fraud Prevention, a set of industry-agreed principles launched through a dedicated working group established by the GLF Board in 2017. The Code serves as a practical framework for international carriers to align on best practices, strengthen defences, and preserve the integrity of global telecoms traffic.

The GLF Code of Conduct

The first Code of Conduct, established in 2018, was aimed to set an industry benchmark for behavior and best practices that carriers should strive to achieve, ensuring consistent action against fraudulent voice traffic across the industry download the examples of common types of Voice Fraud. Since its launch, the Code of Conduct has proven successful and become instrumental on delivering fast and significant progress influencing the industry's approach to combating fraud.

The Fraud Prevention Journey

Amongst the many working groups that the GLF is working on, one of our top priority items is Fraud Prevention. Launched in 2018, the GLF, in collaboration with I3Forum, launched the Code of Conduct (CoC). It sets out the principles that carriers have committed to adhere to, including a commitment to monitor and report on fraudulent activity.

The Voice Code of Conduct

Since 2021, the GLF has enabled signatories to demonstrate compliance with its seven principles through a self-attestation process. In 2024, this was enhanced with a peer-review based on industry self-governance. In 2025, the GLF is introducing a Tiered Attestation system—offering Basic, Advanced, or Excellent levels—aiming to establish a recognised market certification based on adherence to defined fraud measures.

Foreword from the Chair of the GLF's Fraud Working Group


  • "I am honoured to take on the leadership of the Anti-Fraud Working Group. The working group has already made significant advances to take us closer to achieving our mission of having an industry that is free of fraudulent traffic, but the increasing challenges in voice and messaging fraud mean the fight continues. We will build on the successes so far, driving existing activities forward whilst implementing new initiatives and advocating even greater collaboration which I believe will have a positive impact on reducing fraud to ultimately benefit the entire industry.”
    Eloy Rodriguez
    Telefonica Global Solutions, Chief Wholesale Officer
