FATCA registration and FFI list: GIIN composition information

 

GIIN is an abbreviation of Global Intermediary Identification Number. The FATCA Registration System approves foreign financial institutions (FFI), financial institution (FI) branches, direct reporting non-financial foreign entities (NFFE), sponsoring entities, sponsored entities, and sponsored subsidiary branches. Institutions and entities assigned a GIIN can use it to identify themselves to withholding agents and tax administrators for FATCA reporting purposes.

The GIIN, formatted as XXXXXX.XXXXX.XX.XXX, is a 19-character identification number made up of several identifiers. These characters will never contain the letter “O”.
