Why there is debit card zip code?

Your debit card zip code acts as a security layer:

Preventing fraud: When used online, it helps verify your identity by confirming it matches your billing address. If you're in Florida using a California zip code, red flags go up!

Accuracy: It ensures billing information is accurate, aiding smooth transactions and record-keeping.

Compliance: Zip codes help merchants comply with regulations and track purchases for analysis.

Basically, it's your card's secret handshake for secure and accurate transactions.
