Example embodiments of the present disclosure provide an order data interaction method and a server. The interaction method includes: receiving an order request sent by a first communication terminal, and acquiring a first communication number according to the order request; allocating a second communication number to the first communication number, and setting a correlation between the first communication number and the second communication number; sending correlation information to a basic communication server, in which the correlation information carries the first communication number and the second communication number; binding the second communication number with the order request; and sending the order request having a binding relation with the second communication number to a second communication terminal. The data interaction method effectively avoids leakage of users' telephone numbers.
