What a GIIN is
The Global Intermediary Identification Number is the 19-character identifier the IRS assigns through the FATCA Registration System to foreign financial institutions, their branches, direct reporting NFFEs, sponsoring entities, sponsored entities and sponsored subsidiary branches.
It is what a withholding agent uses to establish that your institution is registered, and what a tax administration uses to identify you in FATCA reporting.

How a GIIN is built
| Position | Content | Length | What it means |
|---|---|---|---|
| 1–6 | FATCA ID | 6 | Numbers and uppercase letters. For a lead or a single, the whole FATCA ID. For a member, its first six characters. For a branch, the first six of the associated institution. For a sponsored entity, the sponsor’s FATCA ID. Randomly generated, and it never uses the letter O. |
| 7 | Separator | 1 | A full stop. |
| 8–12 | Type | 5 | 00000 for a lead or a sponsoring entity, 99999 for a single. For a member, the last five characters of its FATCA ID, running 00001 to 99998 then A0000 to ZZZZZ. A branch takes its institution’s. Never uses the letter O. |
| 13 | Separator | 1 | A full stop. |
| 14–15 | Category | 2 | LE lead, SL single, ME member, BR branch, SP sponsoring entity, SF sponsored fund, SD sponsored direct reporting NFFE, SS sponsored subsidiary, SB sponsored subsidiary branch. |
| 16 | Separator | 1 | A full stop. |
| 17–19 | Jurisdiction | 3 | The ISO 3166-1 numeric code of the institution or branch. 999 for other. |
Why a search returns nothing
| Cause | What is happening |
|---|---|
| Registered too recently | The FFI List is a monthly snapshot. An institution registered after the last publication appears only in the next one. |
| Commercial name searched | The list carries the legal name filed with the IRS. A fund marketed under a short name is often registered under a much longer one. |
| Registration cancelled | A terminated or deregistered GIIN is removed from the list. Absence is not proof it never existed. |
| Sponsored entity | It is listed under its own name, but its first six characters are the sponsor’s FATCA ID, not its own. |
| The letter O | A GIIN never contains O. What looks like one is the digit zero. |
| Branch in another country | A branch appears with the jurisdiction code of the country it operates in, not that of the head office. |
Registering a GIIN
- Create an account on the IRS FATCA Registration System and file the institution’s legal name, its tax identification number and its contact details.
- Complete the registration: type of institution (lead, member, branch), country code and FATCA classification.
- Submit. Once the registration is processed, the IRS assigns the GIIN.
- Keep it current. Periodic certifications are due, and a GIIN can be deactivated if the record is left stale.
Deregistering a GIIN
- Sign in to the IRS FATCA Registration System with the account that holds the registration.
- Open the available account options and choose Agreement — Cancel.
- Confirm the cancellation and submit the request.
- Tell the parties that relied on the GIIN, so that no withholding agent keeps using a number that is no longer active.
Frequently asked questions
How often is the FFI List updated?
The IRS republishes it monthly. A GIIN issued between two publications is valid from the day it is assigned, but it will not appear in a search until the next list.
Does a GIIN found here prove the institution is compliant?
No. It proves the institution was registered when the list was published. Compliance with its FATCA obligations is a separate matter.
Can I search by GIIN rather than by name?
This page searches by name. If you hold the GIIN, its structure already tells you the category and the jurisdiction — see how a GIIN is built.
Why does the name in the result differ from the one I know?
Registration uses the legal name. Marketing names, sub-funds and compartments often differ from it.
Do you store the names I search for?
No. The query is passed to the lookup and the answer is shown to you. Nothing is recorded.
We do not have a GIIN yet. Can you obtain one?
Yes. Fund XP files the FATCA registration with the IRS on your behalf and follows it through to the GIIN.
