Premium Random Number Generator

This form allows you to generate random integers in a highly configurable fashion. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs.

The Premium Generator is the most flexible random number generator on RANDOM.ORG. It allows you to generate unique or repeating numbers from large intervals and its advanced mode can also display them in different bases. In addition, the Premium Generator can send email notifications of the numbers to up to 10 addresses and can leave a trail of the last 30 times you used it. This is useful if you need to share the generated numbers with someone who is in a different location (e.g., for play-by-mail games) or if you need a public record of the numbers that you generated at a particular time. Anyone can examine the trails left by people who have used the Premium Generator.

Format in column(s).

Step 2: Uniqueness

Do you want each integer to be unique?
Each integer should be unique (like raffle tickets drawn from a hat)
Repeat integers are allowed (like a series of die rolls)

Step 3: Your Trail

Do you want to place these numbers in your trail so other people can view them? [explain this]

Step 6: Choose Output Format

How do you want the integers to be shown?
On a nicely formatted web page (type text/html)
As a bare-bones text document (type text/plain)

Step 7: Choose Randomization

Do you want a new randomization or one that was prepared earlier? [explain this]
Generate your own personal randomization right now
Use pregenerated randomization from
Use pregenerated randomization based on persistent identifier (max 64 alphanumeric characters)

Step 8: Go!

Be patient! It may take a little while to generate your numbers...
