Arduino Pro mini is based on Atmega328 which does not have a unique ID. It has only device signature which you can read if you turn on Show verbose output during upload in Arduino IDE's File > Preferences.

Could you be confusing the term micro-chip (often applied to any tiny, programmable electronic device) with the manufacturer named "Microchip" (who make the PIC series of micro-controllers, among many other products)? Microchip (the company) does make a line of products that have individually unique IDs. Most manufacturers do not provide unique IDs in their micro-controller devices, and AVR's Atmega 328 series devices do not have unique ID's.
