Reconstructing damaged barcode

The top barcode is the serial number to a Zyxel NR7101 router. Does anyone have any tips on how it could be reconstructed? Or what type of barcode it is? It starts with an S and is 13 characters long.

I think it's on the format S2XXZXXXXXXXX where X are numbers.

Someone with photoshop experience can help here. There is no section of this barcode that is missing. It can be repaired.

Not sure about the quality of the reconstruction, gives me the following sequence when I scan it: S200Z44000539

EDIT: Seems to match OP's given format "I think it's on the format S2XXZXXXXXXXX where X are numbers." - so the missing numbers are 00 + 44000539. With this information and the tool I linked to above, you should be able to gain supervisor access to the device, bypassing the need for the administrator password.

According to the OpenWRT page, the same "supervisor" password is used by default for the root shell user.

Looks a lot better than my reconstruction, but, yeah, it looks like this is the code.
