The National Pension System (NPS) is regulated by the Pension Fund Regulatory and Development Authority (PFRDA) and operated by Central Recordkeeping Agencies — Protean (formerly NSDL e-Gov) and KFin Technologies. Every subscriber receives a 12-digit Permanent Retirement Account Number (PRAN). Subscribers can verify their PRAN, view Tier I and Tier II balances, change investment choice, update nominees and download the annual transaction statement (PRAN Statement / NPS Statement of Holding). The eNPS portal also supports Aadhaar-based account opening, KYC verification, and partial withdrawal applications. Government employees on NPS see contribution data uploaded by their nodal office; corporate and All Citizens Model subscribers manage their own contributions through SIPs or one-time transfers.
