Generally, the business card is printed within 3 working days after card verification and sent to the post office (or EMS express). If the card has special technology (such as ID card, photo card, special-shaped card, etc. ), it will be 2 working days behind the original business card printing time. After the card is sent, the mailing number will be sent to your reserved mobile phone, and the mailing situation can be tracked according to the mailing number.
