How to Register .bank.in or .fin.in Domain Online (2025–2026 RBI Guide)

Registering a .bank.in or .fin.in domain is now a crucial step for banks and financial institutions in India. These domains make it easier for customers to identify the official website of their bank or NBFC, and help protect against fake or spoof websites.

Here’s everything you need to know about registering a .bank.in / .fin.in domain.

What are .bank.in and .fin.in Domains - and Why They Matter (Updated RBI Guidelines)

A .bank.in domain is reserved exclusively for Indian banks approved by the Reserve Bank of India (RBI), while a .fin.in domain is designed for non-banking financial companies (NBFCs) and other financial service providers.

As per the latest Bank in Domain RBI Guidelines (2024–25), all licensed Indian banks are required to transition their primary web domains to .bank.in. The initiative aims to improve digital trust and security across the Indian financial ecosystem.

The Institute for Development and Research in Banking Technology (IDRBT) is the official registrar authorised by RBI to manage and verify these domain registrations.

RBI’s Latest Guidelines for .bank.in and .fin.in Domains

To align with RBI’s cybersecurity directive, IDRBT introduced strict eligibility checks before approving a .bank.in or .fin.in domain. Here’s what’s important:

• Only RBI-authorised banks can apply for .bank.in.
• NBFCs, fintechs, and payment institutions can apply for .fin.in once registration opens.
• The domain must be registered using Digital Signature Certificates (DSCs) of designated officials.
• All domains must implement DNSSEC, SSL certificates, and TLS protocols for security.
• RBI and IDRBT will periodically review compliance and issue renewal reminders.

Who Should Register

• Banks: All Indian banks authorised by the RBI must use a .bank.in domain. Some major banks have already begun the switch.
• NBFCs and other financial institutions: Should plan for a .fin.in domain registration when IDRBT opens that stream (or as per the regulatory schedule).
• If you are unsure about your eligibility or the deadline, check with IDRBT or your regulatory adviser.
