You essentially need to provide your name, registered address, place of birth, date of birth and all tax residencies and TINs (i.e. anywhere where you are or were a registered tax payer and received a TIN).
If you are not a US citizen or US tax resident, then there are no implications for FATCA.
From my understanding, if you are tax resident in a CRS reportable jurisdiction, the bank will report your personal details to the local tax authority and if applicable that same tax authority will then be required to exchange your personal information with tax authority bodies in the other tax jurisdictions involved.
