Online UUID Generator

What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit identifier standardized by the Open Software Foundation (OSF) as part of the Distributed Computing Environment (DCE). It is used to uniquely identify information in distributed systems. UUIDs are designed to be unique across both space and time, meaning that even when generated on different devices or at different times, the probability of two UUIDs being the same is extremely low.

Bulk Version 4 UUID Generation




What version UUID generator is this tool?

This tool generates UUID version 4. UUIDs are divided into different versions based on the method used to generate them. Version 4 UUIDs are generated using random or pseudo-random numbers. They are generated with randomness as the primary factor, making them suitable for use cases where uniqueness and randomness are important, such as in distributed systems, databases, and cryptographic applications.

Why generate UUID version 4?

UUID version 4 is chosen for its randomness and uniqueness properties. Version 4 UUIDs are generated using random or pseudo-random numbers, ensuring that each generated UUID has a high likelihood of being unique. This randomness makes version 4 UUIDs suitable for various applications where uniqueness and randomness are essential, such as in distributed systems, session IDs, message queues, and cryptographic applications. Additionally, version 4 UUIDs do not require access to a global network address or system time, making them easier to generate in decentralized or offline environments.



How to generate Single & Mutiple UUID with this tool?

Single UUID Generator:

  • Automatic Generation: The single UUID generator automatically generates a UUID as soon as the page loads or when you access the tool.
  • Copy Functionality: You can easily copy the generated UUID by clicking on the copy icon located next to the UUID display area. This allows you to quickly paste the UUID into other applications or documents.

Multiple UUID Generator:

  • Quantity Input: You can specify the number of UUIDs you want to generate by entering a quantity between 2 and 50 in the input field provided.
  • Generate Button: Clicking on the "Generate UUIDs" button initiates the generation process, creating the specified number of UUIDs.
  • Viewing Generated UUIDs: The generated UUIDs are displayed in a textarea below the input field. You can scroll through the textarea to view all the generated UUIDs.
  • Copy Functionality: To copy the generated UUIDs, click on the copy icon located next to the textarea. This copies all the UUIDs to your clipboard for easy pasting into other applications or documents.
  • Download Option: Optionally, you can download the generated UUIDs as a text file by clicking on the "Download" button. This saves all the UUIDs in a text file for later use.



UUID Use Cases

  • Database Primary Keys: UUIDs can be used as primary keys in databases, ensuring that each record in the database has a globally unique identifier.
  • Distributed Systems: In distributed systems where multiple nodes need to generate identifiers independently without coordination, UUIDs provide a way to generate unique identifiers without centralized coordination.
  • Session IDs: UUIDs are commonly used to generate session IDs for user sessions in web applications. Each session ID is unique, making it suitable for tracking user sessions across multiple requests.
  • Message Queues and Job Queues: UUIDs can be used as message identifiers in message queues or job identifiers in job queues. Each message or job is assigned a unique UUID to ensure it is processed only once.
  • File and Object Storage: UUIDs can be used as unique identifiers for files or objects stored in a filesystem or object storage system. Each file or object is assigned a unique UUID to identify it uniquely.
  • API Keys and Tokens: UUIDs can be used to generate unique API keys or tokens for authentication and authorization purposes. Each API key or token is unique, allowing secure access to APIs or resources.
  • Tracking Transactions: UUIDs can be used to track transactions in financial systems or other transactional systems. Each transaction is assigned a unique UUID to track its progress and ensure it is processed correctly.
  • Tracking Devices and IoT Sensors: UUIDs can be used to uniquely identify devices or IoT sensors in an IoT (Internet of Things) network. Each device or sensor is assigned a unique UUID for identification and tracking purposes.
  • Version Control Systems: UUIDs can be used to generate unique identifiers for commits, branches, or other objects in version control systems like Git. Each commit or object is assigned a unique UUID for tracking changes and references.
  • Cryptographic Applications: UUIDs can be used in cryptographic applications where uniqueness and randomness are essential. UUIDs generated using cryptographic algorithms provide a high level of randomness and uniqueness, making them suitable for cryptographic purposes.
