What does China Construction Bank mean by "CCHD# card number followed by 4 digits #020"? Is it true or not?

I also received this short message recently, from CCB, inviting me to adjust the temporary credit card limit. After I tried to reply, CCB replied to my adjustment results by SMS three working days later.

If the landlord doesn't reply as soon as possible after receiving the text message, it is also suggested that you can use the mobile phone number reserved in his home system to edit the text message "the amount to be adjusted in the last four digits of CCTE# card number" and apply for a temporary amount in 95533, which is also very convenient. (For example, if the landlord now has a fixed quota of 65,438+00,000 yuan and wants to adjust it to a temporary quota of 65,438+05,000 yuan, and the card number is 8888, edit the short message "ccte # 8888 # 65,438+05,000". If you apply by SMS, the default time of temporary quota is 2 months.
