The Department of Telecommunications (DoT) notified the Telecommunications (Telecom Cyber Security) Amendment Rules, 2025 on October 22, 2025, effective immediately.
The rules establish a Mobile Number Validation (MNV) platform to verify telecom identifiers and bring Telecommunication Identifier User Entities (TIUEs) under DoT cybersecurity oversight.
TIUEs include businesses using mobile numbers for identification, verification, or service delivery, and must comply with DoT standards and share usage details.
The DoT can direct TIUEs and telecom operators to suspend or block numbers without prior notice if misuse is detected, recording reasons in writing.
The rules also strengthen International Mobile Equipment Identity (IMEI) regulations to prevent device tampering and circulation of stolen or cloned phones.
