Frequently Asked Questions

A GUID (Globally Unique Identifier) is a 128-bit number used to identify resources. They are designed to be unique across all computers worldwide, making them perfect for database keys, file identifiers, and more.

GUIDs are designed to be practically unique. The probability of generating a duplicate GUID is extremely low due to the 128-bit number space and the generation algorithm used. For example, generating 1 billion GUIDs per second for about 100 years would only yield a 50% probability of a single collision.
