Press: Deep ID launches SIM Binding for OTP security and SIM swap detection

New capability links mobile numbers to physical SIMs, helping businesses prevent account takeovers and OTP misuse

Deep ID announced SIM Binding, helping teams detect SIM swaps and protect OTP delivery with device-linked SIM context designed for high-risk markets.

Why SIM Binding Matters

OTP-based authentication is widely used but increasingly vulnerable. Fraudsters can bypass OTP security by performing SIM swaps, redirecting messages to a new SIM while retaining the same mobile number.

1. Deep ID’s SIM Binding addresses this gap by:

2. Binding the mobile number to the original SIM and device

3. Detecting SIM changes instantly

4. Flagging or blocking high-risk authentication attempts

5. Reducing account takeovers and identity fraud
