What is a GIIN?
The GIIN, or Global Intermediary Identification Number, is a unique 19-character identifier assigned to foreign financial institutions (FFIs), branches of financial institutions (FIs), direct reporting non-financial foreign entities (NFFEs), sponsoring entities, sponsored entities, and sponsored subsidiary branches through the FATCA Registration System. This number allows these institutions and entities to identify themselves to withholding agents and tax administrators for FATCA reporting.
The GIIN follows the format: XXXXXX.XXXXX.XX.XXX and consists of multiple identifiers. Importantly, it will never include the letter “O.”

How do I apply for a GIIN for my financial institution?
To apply for a GIIN (Global Intermediary Identification Number) for your financial institution, follow these steps:
- Register with the IRS Registration System:
- Go to the IRS FATCA Registration System website : https://www.irs.gov/businesses/corporations/fatca-foreign-financial-institution-registration
- You will need to create an account if you don’t already have one. This involves submitting information about your institution, including its legal name, tax identification number, and relevant contact details.
- Complete the Registration:
- Once logged in, complete the FATCA registration form for your financial institution. This will include details such as the type of institution (e.g., lead FI, member FI, branch), the country code, and the entity’s FATCA classification (such as participating FFI, registered deemed-compliant FFI, etc.).
- Ensure that you include all necessary information and documentation to avoid delays.
- Submit the Application:
- After filling out the required forms, submit your application. The IRS will process it and assign a GIIN to your financial institution if the application is approved.
- Receive Your GIIN:
- Once your registration is processed, you will receive a unique 19-character GIIN. This number can then be used for FATCA reporting purposes and to identify your institution to withholding agents and tax administrators.
- Maintain Your Registration:
- You will need to keep your registration updated by submitting periodic certifications or re-registrations. The GIIN may be deactivated if the information is not kept current.
If you’re unsure about the process or need assistance, it’s recommended to consult with a tax advisor or legal expert who specializes in FATCA compliance.
