If you are using a China Merchants Bank credit card, the cardholder can only modify the credit card ID number by fax or mail. The documents that need to be faxed or mailed include: a copy of the new ID card (marked with "Change of ID number" and the old ID number); a copy of the "Certificate of Change of Resident ID Number" issued by the Public Security Bureau (only the new ID card needs to be provided if the ID card is naturally upgraded. Copy of ID card); if using a military officer’s ID card, please provide a copy of the change certificate issued by the army. It will take about 5 working days after our bank receives the complete information to complete the change. Fax number: 021-38566200
