Do you trust businesses more when they use verification methods other than SMS passcodes?
Authsignal has launched Number Verify, a service that replaces traditional SMS passcodes with silent network authentication or SIM-based verification. The tool is now available across major mobile carriers in the United States and via Telstra in Australia.
Why it matters
The service addresses new NIST guidance that categorizes SMS authentication as a restricted authenticator, requiring firms to adopt more secure alternatives. By integrating carrier data, businesses can move away from volatile SMS delivery methods for identity verification.
Authsignal processes over 12 million authentication events monthly across 17 countries. The new platform enables silent network authentication, removing reliance on SMS delivery for identity verification.
The players
Authsignal
An identity authentication firm that provides risk logic and orchestration services to businesses across 17 countries.
Aduna
A data platform provider that aggregates and serves network-level signals from mobile carriers for authentication tasks.
Telstra
A major Australian telecommunications company providing the network infrastructure required to facilitate Number Verify in that region.
The details
Number Verify functions by tapping into carrier-side data signals through a single integration point provided by Aduna. Instead of sending a one-time passcode to a user, the system performs a silent authentication check against the SIM card or network status. This process allows businesses to integrate verification directly into existing risk logic and orchestration paths without exposing users to SMS-related interception risks.
Timeline
October 2, 2026: Authsignal officially launched the Number Verify service.
The Tech Race
The launch aligns with the updated security standards set by NIST SP 800-63B-4, which mandates the use of unrestricted alternatives to SMS. This move positions Authsignal to compete with traditional authentication providers by offering a direct integration for carrier-grade identity checks.
Businesses can now integrate this verification method into their current security workflows to reduce dependency on SMS. Users may see a transition toward silent, background verification processes that eliminate the need to manually enter codes sent via text.
The takeaway
The move toward carrier-based authentication is accelerating as firms scramble to meet stricter NIST identity standards. Developers should track the integration of these carrier signal platforms as they replace legacy SMS-based authentication workflows in production environments.
