Is there a way to get a unique ID on a Raspberry Pi?
There is a simple way to use an already existing unique number within the device. The serial number of the chip will be good enough to use as a unique key. The following command will give the details of the cpu. We can find a serial number from this details and can be used as a unique id.

How to get the serial number of a Raspberry Pi?
To build the code, run the following command on Raspberry Pi terminal: You can run the following command on terminal to extract Hardware ID: How do I get the serial number? Thanks for contributing an answer to Raspberry Pi Stack Exchange!
What does a device tree on a Raspberry Pi represent?
A Device Tree represents the hardware configuration as a hierarchy of nodes. Each node may contain properties and subnodes. Properties are named arrays of bytes, which may contain strings, numbers (big-endian), arbitrary sequences of bytes, and any combination thereof. By analogy to a filesystem, nodes are directories and properties are files.
How does the serial number on a Raspberry Pi work?
There is no diferentiator between my PI0 serial and the one posted by Alex Chamberlain Raspberry Pis have “randomly assigned” serial numbers that are written to non-volatile memory. Long discussion here on whether or not these serial numbers are unique, but the bottom line is that the algorithm is proprietary to the chip manufacturer.
How does Raspberry Pi get a 64 bit address?
The IPv6 address auto configuration process uses NDP protocol to discover the 64-bit network address in the 128-bit address. This process will give all your devices within the same network the same 64-bit prefix. The aforementioned EUI-64 is used to populate the 64-bit station address, resulting in a 128-bit globally unique IPv6 address.
What kind of address does Raspberry Pi NIC have?
Every NIC, including the USB one used on the Pi, have an 48-bit MAC address, for example, 14:cf:92:20:26:3c. Every 48-bit MAC address have a unique one-to-one mapping to an EUI-64 address by masking off the last two bits in the third byte ( 92 to 90) and insert the bytes feff in between the third and fourth byte.
Is the serial number on a Raspberry Pi unique?
Which effectively means, “nobody knows if the serial number can be counted on to be truly unique”. It’s apparently considered “unique enough” to protect a £2.40 MPEG-2 license key though – if that lets you sleep better 🙂

What kind of adapter do I need for Raspberry Pi?
A USB TTL adapter with 3.3V and 5V voltage output can be used for many serial modules. These sensors were originally developed for the Arduino and can be read via UART. The Raspberry Pi has two pins (pin 8 / GPIO14 and pin 10 / GPIO 15), but they work with 3.3V.
