As soon as you receive your JCB Card, look for the signature panel at the back of the card. Your journey with your JCB card begins by putting your signature in the box labeled "Signature." Don't forget!

You will be asked for your signature to prove that the card you are using is in fact your own.*1
Try not to make your signature too ordinary or easy for others to copy. Make sure to make your signature something special and unique that only you can reproduce.

*1If using your IC-chip-embedded JCB card at a store with an IC-card-compatible terminal, your PIN number may be requested instead of a signature.

*2When using your JCB card for internet shopping, you may need to enter its security code. Your security code is the last three digits of the seven numbers printed in the upper right area of the signature panel on the back of your card.

Check the name and expiration date shown on your card

Make sure that the name on your card matches your name exactly. The expiration date tells you how long your card is valid for.

* Your card is valid until the last day of the month shown in the expiration date.
<Example>If your card's expiration date is "03/20" you can use your card until the last day of March, 2020.

Your card is delicate. Handle it with care.

The magnetic stripe on the back of your card is a vital component for storing your card's data and processing transactions online. If this area is damaged your card will become unusable. Do not place your card near any strong magnets. Try not to bend, scratch, or damage your card in any way.

Only you can use your own card.

Your card is meant for sole use of the cardholder only and any charges to the account will be the cardholder’s full responsibility. Avoid lending your card to others as any transactions made on the card would be charged to the original cardholder.

Be careful with your PIN number.

Keep your PIN number secure, avoid easy to find or guess passwords
Avoid writing down your PIN numbers. If the PIN number is written down, do not store your card in the same place as any written record of your PIN number. Easy to guess passwords that must be avoided are those such as your birthday, home/mobile phone number, the one for your mobile phone, mailbox, locker, or any other PIN number you may have.

Never tell anyone your PIN number.
JCB, financial institutions, the police, or any other entity will never ask for your PIN number by phone or e-mail.

The following types of PIN numbers are easily guessed should you lose any other personal documents with your card. They are not recommended.

  • Numbers related to your birthday
  • Numbers in your phone numbers (home, work, mobile)
  • Numbers in your address (block number, street number, etc.)
  • Four of the same number (e.g., 1111, 5555, etc.)
  • Common sequence numbers (e.g., 1234, 9876 etc.)

How to Change/Check Your PIN Number

If you need to change or check your current PIN number, please contact the company that issued your JCB card.

*Some card issuing companies distribute cards with no PIN number or with a PIN number that cannot be changed.
