individual taxpayer identification number (ITIN)

The Treasury Department expanded bank data-sharing rules to support President Donald Trump’s immigration enforcement efforts, allowing banks to rapidly share customer information suspected of lacking legal status. The changes, framed as anti-fraud measures, follow an executive order directing banks to scrutinize customer citizenship without explicitly mandating data collection. Banks can now share information in real time and use flags like individual taxpayer identification numbers (ITINs) historically linked to undocumented immigrants.
