Mock Device ID Generator
Used by developers, writers, and creators worldwide.
A mock device ID generator produces fake hardware identifiers — MAC-style addresses, device tokens, and serial numbers — for testing and sample data. Code that registers, tracks, or displays devices needs realistic identifiers without using real hardware values, which can be sensitive. This tool generates correctly formatted IDs in a few common styles, so you can seed a device database, mock an IoT fleet, or fill example configuration in seconds. Choose a format and how many you want, then copy them in. It is ideal for testing device registration, building IoT mock data, and documentation. Each identifier is random and corresponds to no real device, which keeps them safe to share. They follow the right shape for their format, so they exercise your parsing and storage realistically.

FAQ
what is a MAC address
A MAC address is a hardware identifier assigned to a network interface, written as six pairs of hexadecimal digits separated by colons. It identifies a device on a local network. The ones here are random and match the format without belonging to real hardware.
are these safe to use
Yes. Every identifier is randomly generated and corresponds to no real device, so they are safe for tests, documentation, and sample data. They follow the correct format for each style, which is what matters for exercising your code.
can i use these in production
They are intended for testing and mock data. For production device identifiers, generate them from your own trusted source with the uniqueness and format guarantees your system needs, rather than reusing throwaway values from a tool.
