This tool is a quick and reliable online utility for generating one or more UUIDs (Universally Unique Identifiers), also known as GUIDs. A UUID is a 128-bit string of random characters, formatted as xxxxxxxx-xxxx-4xxx-xxxx-xxxxxxxxxxxx, that is statistically guaranteed to be unique across all systems globally. Our generator provides Version 4 UUIDs, the most common and robust type, making them ideal for use as unique keys in databases, unique identifiers in distributed systems, secure tokens in APIs, or for generating mock data for testing. The advantage is that you can generate as many as you need right now without worrying about coordination or collisions.

Using the tool is simple and requires no software installation. When you first load the page, a single, new UUID is generated and displayed instantly for immediate use. To generate multiple unique IDs for tasks like database seeding or bulk assignments, use the Bulk UUID Generation section. Simply enter the number of UUIDs you require in the “How Many?” field (e.g., enter 10 for ten unique IDs), and then click the Generate button. The resulting list of UUIDs will appear, ready for you to copy and paste into your application, database, or document.
