Common technical standards are intended to let participating financial institutions exchange customer-authorized information through India’s Account Aggregator (AA) framework, even when they use different AA systems. That is technical interoperability—not a guarantee that every bank, lender, account type, and NBFC-AA is connected to every other one. Customers still need to check the specific app and institution flow they plan to use.

What interoperability means in the Account Aggregator framework

An Account Aggregator is an RBI-regulated non-banking financial company that acts as a consent-based intermediary for sharing a customer’s financial information. A Financial Information Provider (FIP), such as an institution holding financial information, can send it through the AA framework to a Financial Information User (FIU), which seeks to use it for a permitted purpose.

The Reserve Bank of India’s November 8, 2019 circular says common technical specifications were introduced to support data movement among ecosystem participants in a “secured, duly authorised, smooth and seamless” way. ReBIT’s API specifications define common financial-information formats and representations intended to support compatibility. RBI’s 2025 Directions refer participating RBI-regulated entities to ReBIT’s technical specifications, including updates.

In practical terms, shared standards can help systems understand and exchange data in consistent formats. They do not, by themselves, make every institution or account available in every AA app.

What customers can—and cannot—assume

Consent remains central

Using an AA is voluntary. A customer gives an instruction and explicit consent for information to be shared for the stated purpose. The Department of Financial Services describes the framework this way: “No financial information of the customer is retrieved, shared or transferred by AA framework without the explicit consent of the customer.” An AA facilitates the transfer; it is not the lender and does not own the customer’s financial information.

Interoperability does not mean universal availability

Compatibility at the technical level is only one part of a working connection. The relevant FIP and FIU must also be available and operational in the chosen flow, and the account type must be supported. Sahamati said on February 13, 2025, that standardized protocols had achieved technical interoperability, while integrations still involved bilateral agreements, compliance requirements, and separate onboarding. It described SahamatiNet and a Router as initiatives aimed at reducing repetitive onboarding; that is Sahamati’s stated work and aim, not an RBI guarantee that all integrations are complete.

So the answer to “Can I use any Account Aggregator with my bank?” is: common standards are intended to make cross-system exchange possible, but you should confirm that your bank, account, and intended FIU appear in the particular AA flow. Likewise, a customer seeking a loan should not assume that the lender accepts data from every AA merely because the ecosystem uses common standards.

How to check a specific account-sharing flow

  1. Open the AA app or service you intend to use. Check its institution or account-discovery list for the FIP and the account type you want to link.
  2. Start the relevant request. If you are sharing information with a lender or another FIU, verify that the intended recipient and purpose are presented in the flow.
  3. Review the consent details before approving. Read which information is requested, for what purpose, and for what period or frequency, as shown in the consent request.
  4. Use the app’s consent controls and notifications. Check that you can manage the consent and receive the relevant status or activity notifications; do not approve a request whose scope you do not understand.

Customer safeguards and the 2026 adoption deadline

ReBIT’s “Account Aggregator – Standard to enhance Customer Protection and User Experience,” dated April 30, 2026, covers onboarding, account discovery and linking, consent management, user experience, technical security, and integration. Among the areas it addresses are legible consent fields, customer control over consent operations, simpler AA app design, timely notifications, two-factor authentication, SIM and device binding, and secure AA–FIU integration.

The standard’s notice says NBFC-AAs and FI-Us must adopt it by October 31, 2026. As of October 7, 2026, that date is still in the future; it should not be read as evidence that every participant has already completed adoption.

How large the ecosystem was on March 31, 2026

The Department of Financial Services’ progress figures, attributed on its framework page to Sahamati and stated as of March 31, 2026, show broad participation, but they do not establish that a particular customer’s institutions are connected in a particular flow.

The practical takeaway for choosing an AA flow

Common specifications provide the technical basis for interoperability, while actual access depends on institution onboarding and the specific app, account, and recipient involved. Before approving a request, check that the institutions and account you need are supported in that flow and read the consent scope shown on screen.
