The 4 digits before the CVV (Card Verification Value) on a credit card are commonly known as the CID (Card Identification Number). This number is typically printed on the front of the card, just above and to the right of the main credit card number. The CID serves as an additional security feature to help verify the authenticity of the card during online or phone transactions.
The purpose of the CID is to provide an extra layer of protection against fraudulent activities. By requiring the CID, merchants can verify that the person making the transaction has physical possession of the card. It is important to note that the CID is not embossed on the card like the main credit card number, expiration date, or cardholder’s name.
The CID is a 4-digit code that is unique to each credit card. It is often referred to as the CVV2 (Card Verification Value 2) or CVC2 (Card Validation Code 2). The CID is different from the CVV, which is the 3-digit code found on the back of the card, typically in the signature panel.
When making a purchase online or over the phone, you may be asked to provide the CID along with other card details. This helps ensure that the transaction is legitimate and reduces the risk of unauthorized use of your card information.
It is important to keep your CID confidential and not share it with anyone. Treat it as sensitive information, similar to your credit card number and other personal details. Safeguarding your CID helps prevent potential misuse of your credit card.
