Every MikroTik product ships in a cardboard box with a label. This label contains the MAC address, the model number, and the Serial Number. If you manage a stockroom, it is standard practice to record the S/N from the box before the device is deployed to a remote site.
If your specific MikroTik model (e.g., CCR2004, RB5009, hAP ax3) has a hidden serial number location, consult the official MikroTik Wiki or the PDF manual included on the CD that came with your device.
It’s a (typically 12–16 characters) assigned to every MikroTik device during manufacturing. Unlike MAC addresses (which can be spoofed or changed via software), the serial number is hard-coded into the device’s ROM and cannot be modified by the user.

Add this to your MikroTik scheduler to log the identity and serial number to a central server:
