Major U.S. mobile carriers AT&T, T-Mobile, and Verizon have formed a partnership with Aduna to implement standardized 5G Network APIs across the United States, with a planned launch in 2025. The initiative builds upon recent carrier-led API standardization efforts and focuses on delivering carrier-grade network API capabilities that enhance security and fraud detection across mobile networks.
The initial rollout will feature two primary APIs: a Number Verification API enabling secure authentication of mobile numbers through operator networks, and a SIM Swap API designed to combat unauthorized SIM swap fraud. These standardized interfaces will be accessible nationwide upon the service’s 2025 launch. The SIM Swap API arrives at a critical time, as SIM swap fraud has caused mounting losses and increased scrutiny of carrier security measures.
The collaboration builds upon the CAMARA open-source project, which receives support from the GSMA and the Linux Foundation. The project enables the integration of network APIs from multiple operators into a unified platform, allowing developers to create applications that work consistently across different carrier networks. The initiative marks a significant evolution from earlier carrier authentication efforts like ZenKey, which aimed to provide password-free authentication across mobile networks.
“We’re witnessing a pivotal moment for the mobile ecosystem that demonstrates the reality of global coverage capabilities,” said Aduna CEO Anthony Bartolo, “while enabling faster, carrier-backed authentication at scale.” The announcement follows Aduna’s recent expansion of its network API ecosystem through strategic partnerships with major communications providers.
AT&T’s Senior VP and Network CTO Yigal Elbaz explains that the collaboration transforms participating networks into a platform offering advanced capabilities that provide significant value across the developer ecosystem.
The implementation is expected to affect multiple sectors, including financial services, e-commerce, and digital identity verification. Dan Thygesen, SVP at T-Mobile Product, Partnerships & Growth, emphasizes how Network APIs can enhance user experience while protecting sensitive data.
Verizon’s Senior Vice President of Technology and Product Development, Srini Kalapala, points to new opportunities for businesses to enhance application capabilities and improve customer experiences through these network APIs.
The implementation works within existing regulatory frameworks, including strong customer authentication (SCA) standards, European eIDAS regulations, and emerging digital identity frameworks in the United States. The regulatory compliance ensures the initiative meets current security requirements while preparing for future regulatory developments in digital identity verification.
