Just like the game has different factions, credit cards also have their own gangs. The six major credit card organizations in the world are UnionPay, Visa, MasterCard, American Express, Dai Lai, and Japan JCB. How do you differentiate between these six organizations, Dika?

I believe everyone is familiar with UnionPay. The card we use most in China is probably the UnionPay card. The UnionPay card number is 16 digits long, starting with 62, and the credit card security code CVN2 is the last three digits after the signature field on the back of the card. Except for MasterCard, the location of the anti-counterfeiting code of the other four major card organizations is the same as that of UnionPay.

VISA is the world's largest international credit card organization. The card number is 16 digits long and starts with 4. This card is also very common for us and easy to apply for.

The length of the MasterCard card number is also 16 digits, starting with 5.

American Express is engaged in both issuing and acquiring businesses. The card number is 15 digits and begins with 34 or 37. The security code cid is 4 digits and is located above the card number on the front of the credit card. China Merchants Bank’s Centurion is an American Express card.

Like American Express, Lycra is a closed and independent bank card organization. The card number is 14 digits, starting with 30 or 36.

The Japanese JCB card has a 16-digit card number, starting with 35. This kind of card is generally rare. Related questions and answers: What are the credit card repayment methods? 1.
