GUID Generator – Create Unique Identifiers Instantly
Our GUID generator makes it easy to create as many as GUIDs in our system. Globally Unique Identifiers (GUIDs) also known as Universally Unique Identifiers (UUIDs). You just need to select the options to make it suitable for your project needs and ensuring the uniqueness and reliability.
What is a GUID (or UUID)?
GUIDs are mostly used in IT systems like software development, databases and distributed systems where uniqueness is required in order complete the task of the project. It is a 128-bit number used so it is pretty unique. It is widely used in database primary keys, for file names, or for data sync projects.
Why Use GUIDs?
As far as we are concerned, GUIDs are widely used for:
- Databases : As primary keys to ensure every record has a unique identifier.
- Software Development : To identify objects, components, or versions in programming languages like Java, C#, Python, and SQL.
- Distributed Systems : To uniquely identify components.
- File Systems : To avoid duplicate names in complex directories.
- Data Synchronization : To merge data from different sources without conflicts.
How Unique Are GUIDs?
The 128-bit structure makes the GUIDs extremely unique. Like:
- If 1 billion GUIDs were generated every second for an entire year, the probability of a duplicate would be only 50%. That makes it almost not possible.
- Each GUID is effectively unique, even when generated across other websites like us, who is helping to generate GUIDs for technical people.
How to Use Our GUID Generator
- Generate a GUID : Click the "Generate" button to instantly create a unique identifier.
- Copy and Paste : Use the generated GUID(s) in order to use them in your project.
- Bulk Generation : Need multiple GUIDs? Use the slider to generate up to 100 GUIDs at once.
Our online tool is fast, reliable, and free to use—perfect for developers, database administrators, and testers.
About GUIDs and Standards
GUIDs follow the RFC 4122 standard, ensuring they are globally unique.
