Why do we need to enter our social security number for using a prepaid visa credit card?

Entering your Social Security number (SSN) when using a prepaid Visa credit card is often required for identity verification and compliance with federal regulations, such as the USA PATRIOT Act. This helps prevent fraud, money laundering, and other illicit activities by ensuring that the card is linked to a legitimate individual. Additionally, it may be necessary for the card issuer to report certain transactions to the IRS, especially if they exceed specified limits.
