CVV Number Format

Protecting Against Skimming

Addressing Friendly Fraud

The CVV code isn't just against criminal fraud. It also helps with "friendly fraud." That's when a buyer argues a real buy later, saying they didn't get it or it wasn't right. The merchant with the CVV on hand can show the buyer had the card and approved the buy. This can block the buyer from wrongly denying they bought it.

Processing CVV Codes

Merchants have a big job in making online payments safe. They need to send the CVV code to the bank for every purchase. This code is checked by the card issuer against their records to make sure the sale is real.

Merchant Requirements

Merchants must follow rules set by payment networks closely. They have to keep CVV codes safe and not keep them after the sale. If merchants break these rules, they can face big fines or lose their ability to sell things online.

Authorization Process

The CVV code lets the card issuer know the purchase is legit. They check the code against their files. The sale goes through only if the codes match.
