The pairing code used for Bluetooth communication is a security feature which is intended to check unauthorised connection over the Bluetooth link. The Bluetooth Pairing code is a code which the users of both the bluetooth enabled devices must enter in order to authorize the one of device to connect/pair with the other. The bluetooth pairing code is provided by the user, and the same code must be entered in both the devices in order to pair.
So, you don't need any Pairing code. You can enter any number in the phone, but make sure that you enter the same code in your PC as well, or your PC will not be authorised to make connection with the phone. for Example, you can use ' 1 ', of course, without quotes, in your phone and the PC simultaneously.
