RouterBoard serial number

Greetings to you dear engineers!

I have the question. Could anyone help me with that? All routerboards nave a serial number, which can be displayed with using

/system routerboard> print

command.
Is the serial number protected and if it is, how serious is the protection and where is the serial number stored (NAND, EEPROM)? For example, if I copy EEPROM chip with using of the programmer device and installed on the board the same model, will I have two boards with the same serial numbers?

As you can guess, this is secret information :slight_smile:
