🆔 Random ID & UUID Generator

Generate unique alphanumeric IDs and standard UUIDs for database keys and testing.

ℹ️ About Random ID & UUID Generator

The Random ID & UUID Generator is a utility for developers who need unique identifiers for database records, session keys, or filenames. It provides two types of IDs in a single click:

  • Custom Alphanumeric ID: A string of a length you choose, using uppercase letters, lowercase letters, and numbers.
  • UUID v4: A 128-bit Universally Unique Identifier, the industry standard for unique keys across distributed systems.

Both are generated using cryptographically secure random sources, ensuring they are unpredictable and highly unlikely to collide even in massive datasets.

📖 How to use Random ID & UUID Generator

  1. 1. Specify the desired length for the custom alphanumeric ID.
  2. 2. Click 'Run Tool' to generate both types of IDs.
  3. 3. Copy the format that best fits your technical requirements.

Frequently Asked Questions

Is UUID v4 truly unique?

Yes. While theoretically there is a chance of collision, the number of possible UUIDs is so large (2^122) that it is practically impossible to generate a duplicate in any realistic scenario.

When should I use Alphanumeric over UUID?

Alphanumeric IDs are shorter and more human-friendly, making them good for tracking codes or public URLs. UUIDs are better for internal database primary keys and distributed systems.

Are these IDs secure?

Yes. Because they are generated using the <code>secrets</code> module, they are suitable for security-sensitive tokens and session identifiers.
