The invention discloses a testing method for a physical address of a network card. The method comprises the following steps of (1) providing a bar-code scanner and a flow card; (2) connecting the bar-code scanner and a to-be-tested board; (3) setting a program and opening a program testing interface; (4) scanning a bar code on the flow card by utilizing the bar-code scanner and displaying the scanned correct physical address in an edit box of the testing interface; (5) obtaining the actual burning physical address in the network card of the to-be-tested board through the program; (6) judging whether the obtained actual physical address is the same as the scanned correct physical address, if yes, executing the step (7), otherwise executing the step (8); (7) displaying the testing interface successfully, closing the program and recording a testing result; and (8) failing to display the testing interface, closing the program and recording a testing result. According to the testing method for the physical address of the network card, the testing method is not only unified, but the result after testing is stored to facilitate subsequent tracing inquiry.
