UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information. Version 4 UUIDs are randomly generated, making collision probability astronomically low.

Are UUIDs truly unique?

While not mathematically guaranteed, UUID v4 has 2^122 possible values. The probability of generating a duplicate is essentially zero for practical purposes.

When should I use UUIDs?

Use UUIDs as database primary keys, API resource identifiers, session tokens, or any time you need a unique identifier without a central authority.
