Fiat24, a crypto debit card issuer, has notified certain users to provide their Tax Identification Number (TIN) in compliance with the Common Reporting Standard (CRS). This requirement affects users who completed KYC using a passport before January 1, 2026. For Chinese users, the TIN corresponds to their ID number. Users must submit the required information by July 31 to avoid potential deactivation of their Fiat24 cards.
