Generated UUIDs

In software development, you often need a reliable way to create unique identifiers for things like database entries, user sessions, or transaction records. Using simple sequential numbers can be problematic, especially in distributed systems. For this reason, a universally unique identifier is the standard solution.

Our free online UUID generator is designed to provide these identifiers instantly. In fact, this tool creates Version 4 UUIDs, which are based on random numbers to ensure uniqueness. As a result, you can get one or multiple UUIDs for your project with a single click.

How to Use the UUID Generator

  1. Set the Amount: First, enter the number of UUIDs you wish to generate at one time.

  2. Choose Your Options: Next, you can use the checkboxes to select whether you want the UUIDs in uppercase or if you want to remove the hyphens for a more compact format.

  3. Generate UUIDs: After that, simply click the “Generate” button.

  4. Copy Your Results: Finally, a list of unique UUIDs will appear in the results box, ready for you to copy and use in your application.

UUID Generator FAQs

  • Q: What is a UUID? A: A UUID (Universally Unique Identifier) is a 128-bit number that developers use to uniquely identify information in computer systems. Consequently, it is a reliable way to avoid ID conflicts.

  • Q: How unique are the UUIDs from this generator? A: This tool generates Version 4 UUIDs, which are created using a secure random number generator. The mathematical probability of two V4 UUIDs being the same is astronomically low. Therefore, they are considered unique enough for virtually all applications.

  • Q: Is the information I enter into this tool saved anywhere? A: No. We take your privacy seriously. In fact, all UUID generation happens directly in your browser. This means your data is never sent to or stored on our servers.
