The "VALIDTHRUMONTH/year" on CCB's credit card represents the year when the credit card expires. For example, 12/2 1 means that the credit card will expire at the end of 202 1 12.
(In case of business changes, please refer to the actual situation. )
There is a 1 on the credit card of CCB after the first year.
The date on the front of CCB's credit card indicates the validity period of the card, and the bank will automatically renew it for you within this period. The latter 1 has no influence in the process of using the card. As far as I know, it's just the number of card renewals. In other words, the number of times the card is damaged and replaced with a new card is displayed on the card surface. For example, if the chip or magnetic stripe of this card is damaged or the card surface is unusable or a new card is replaced due (in these cases, the card replacement will not be++), you can apply to the bank for a new card, and then the new card number you get will show "2". If the loss is reported, the new card++will change, and the numbers here will not be updated in order.
What does it mean that there is a number 1 next to the date of my CCB credit card?
My CCB credit card also has this number, which may be related to the number of card applications, because after the card expires, the number becomes 2. Anyway, it doesn't affect the use, don't worry.
This concludes the introduction of CCB credit card number 1 and CCB credit card number card. I wonder if you found the information you need from it?
