UUID Validator
Validate and verify UUID (Universally Unique Identifier) format and structure. Check if your UUID is valid and get detailed information about its version and format.
UUID Validation
UUID validation ensures that a given string conforms to the UUID standard format and structure. This tool helps developers verify UUID integrity and extract detailed information about UUID components.
Validation Process
Our validator checks multiple aspects of a UUID:
Format Validation
Verifies the UUID follows the standard 8-4-4-4-12 hexadecimal format with proper hyphen placement.
Version Detection
Identifies the UUID version (1, 2, 3, 4, or 5) and validates version-specific requirements.
Variant Validation
Ensures the UUID variant bits are correctly set according to RFC 4122 specification.
Extracted Information
For valid UUIDs, our tool extracts and displays relevant information based on the UUID version:
- Version 1: Timestamp, clock sequence, and node information
- Version 4: Random/pseudo-random number validation
- All versions: Format structure and variant information
Common Use Cases
UUID validation is essential for data integrity checks, API input validation, database migrations, debugging distributed systems, and ensuring proper UUID generation in applications.
