UUID Generator
Quickly generate random v4 UUIDs.
What is a UUID or GUID?
A Universally Unique Identifier (UUID), also known as a Globally Unique Identifier (GUID) in the Microsoft ecosystem, is a 128-bit label used to uniquely identify information in computer systems. Because the total number of available UUIDs is so massive, the probability of generating a duplicate is practically zero. This makes them perfect for database primary keys, session IDs, and tracking unique transactions.
Version 4 UUID Generation
Our UUID Generator produces Version 4 UUIDs. Unlike Version 1 which relies on MAC addresses and timestamps, Version 4 UUIDs are generated using completely random or pseudo-random numbers. This ensures high entropy and cryptographic security, making them the standard choice for modern web and database applications.
Bulk GUID Creation
Need more than one identifier? Simply increase the count in the tool above to generate up to 100 unique UUID strings instantly. You can easily copy the entire batch to your clipboard for use in bulk database seeds or mock data generation.
