What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit identifier that is unique across space and time. Version 4 UUIDs are randomly generated and have a virtually zero chance of collision.
UUID Format
Standard format: 8-4-4-4-12 hexadecimal characters (e.g., 550e8400-e29b-41d4-a716-446655440000). The 13th character is always the version number (4 for v4).
