Random Number Generator Online
Generate a list of random numbers within a custom range, with or without duplicates. Free to use, no signup required for occasional use.
What is the Random Number Generator?
The Random Number Generator produces a list of random numbers within a range you define. Enter a minimum and maximum value, how many numbers you want, and whether duplicates should be allowed, and the tool instantly generates the list. It's commonly used for raffles and giveaways, picking lottery-style numbers, sampling data, assigning random IDs, or any situation where you need unbiased random numbers quickly. When duplicates are disallowed, the tool uses a shuffle so every eligible number has an equal chance of being picked, and it will warn you if your requested quantity is larger than the available range allows.
How to use it
Enter your minimum and maximum values to define the range, then set how many random numbers you want generated. Toggle 'Allow duplicates' on or off depending on whether repeated numbers are acceptable — for example, turn it off when picking unique raffle ticket numbers. Click 'Generate' to see your list of random numbers, then use the copy button to paste them anywhere you need.
