India’s Department of Telecommunications (DoT) has directed telecom operators to implement Calling Name Presentation (CNAP) service on mobile phones to help reduce spam and scam calls. The implementation order came during a recent meeting between the DoT and telecom operators, building upon earlier initiatives launched by the Telecom Regulatory Authority of India (TRAI) to combat fraudulent calling practices.
The initiative faces technical challenges, particularly regarding 2G networks. Telecom operators have informed the DoT that while trials are ongoing, implementation will proceed once the technology stabilizes. However, the service cannot be implemented for 2G users due to technological limitations of the network. The limitation poses significant challenges since many of India’s rural residents still rely on 2G connectivity.
The Telecom Regulatory Authority of India (TRAI) previously recommended that the government require telecom operators to implement CNAP and mandate handset manufacturers to enable the feature within six months. The recommendation aimed to reduce customer harassment from unknown callers and supports other digital fraud prevention measures recently implemented across India’s telecommunications sector.
Along with the CNAP implementation, telecom operators are addressing quality of service (QoS) requirements. The Cellular Operators Association of India (COAI) has highlighted ongoing challenges including Right of Way issues, spectrum interference, and infrastructure constraints that affect network deployment, particularly for 5G services.
As part of broader security measures, India has mandated Aadhaar-based biometric verification for all new SIM card issuances. The verification system requires SIM card sellers to authenticate customer identity through biometric verification linked to Aadhaar. The DoT has undertaken enforcement actions against non-compliant retailers, with over 365 First Information Reports filed against those who issued cards using fraudulent documents.
The CNAP implementation is part of India’s expanding digital security infrastructure. All biometric data collected during Aadhaar verification is encrypted immediately upon capture, supporting the country’s digital identity verification framework. The initiative contributes to a larger ecosystem of digital identity measures, including recent implementations for postal savings accounts and various government services.
