American telecom service providers Verizon, AT&T, and T-Mobile—venture partners of Aduna, an API joint venture (JV) between Ericsson and global telecom carriers—are set to introduce the first advanced 5G network Application Programming Interfaces (APIs) for Number Verification and SIM Swap protection in the United States. Slated for a nationwide rollout in 2025, these APIs will provide businesses and developers with carrier-grade authentication solutions to combat fraud and streamline verification processes.

Secure 5G Network APIs
“For the first time, three of America’s leading telecom operators are working together to support standardized, open network APIs including by driving interoperability, fostering industry-wide innovation and reshaping the global digital landscape,” Aduna and Ericsson said in a joint statement on February 27. They added, “By unifying network capabilities across major US telecom providers, this initiative will unlock new opportunities for innovation in financial services, e-commerce, digital identity and more.”
What Are the New 5G APIs?
The Number Verification API, set to become available nationwide from Aduna in 2025, will enable user authentication by verifying mobile numbers through operator networks, leveraging data from smartphones’ network connections. The API will help mitigate risks such as fraudulent SMS-based authentication. Meanwhile, the SIM Swap API will add a critical security layer against unauthorized SIM swaps—a common tactic in account takeover fraud.
Together, these “Advanced APIs” are expected to strengthen security measures and enhance customer trust and safety.
