Credit card mailing address can be modified over the phone. Basically there is no impact

But there are some restrictions on changing the mailing address

You can change the mailing address when the credit card has been approved and has not yet been mailed

If the credit card is under review or has been mailed, it cannot be modified.

You must apply by phone via the mobile phone number you reserved when applying for a credit card, and others cannot modify it.

Note: If the card has been mailed, the mailing address cannot be modified. If you still need to modify it, you need to report the loss of the credit card that has been mailed and remail a new card. At this time, the new card mailed can be changed. Mailing address
