Random Number Generator
Pick random numbers in any range. Perfect for giveaways, dice rolls, and raffles.
What Is a Random Number Generator?
A random number generator picks numbers from a range you define, without following a pattern you could predict in advance. Instead of choosing a number yourself — which is rarely as impartial as it feels — you set the lowest and highest values you want, and the tool selects numbers from within that range for you. Every value in the range has an equal chance of being picked each time the generator runs.
This generator works with whole numbers and gives you control over how many results you get in one go. You can also decide whether the same number is allowed to appear more than once. That single setting makes the tool flexible: with duplicates allowed it behaves like repeated dice rolls, while without duplicates it behaves like drawing distinct lots, tickets, or names from a hat, where each result can only come up once.
How to Use the Random Number Generator
- Enter your lowest allowed value in the Minimum field and your highest allowed value in the Maximum field.
- Enter how many numbers you want in the How many numbers field, from 1 up to 1,000.
- Tick Allow duplicates if the same number may appear more than once, or leave it unticked for all-unique results.
- Click the Generate button and read your numbers in the result chips that appear below.
Who Uses a Random Number Generator?
Teachers use it to pick students fairly, call on volunteers, or create practice questions. Organisers of giveaways, raffles, and social media contests use it to select a winning entry number in a way they can demonstrate was impartial. Gamers and tabletop players use it as a substitute for dice or to set up random challenges, while developers, testers, and spreadsheet users use it to produce sample values quickly when building examples, test cases, or mock data sets.
Tips for Better Results
- Check that your maximum is equal to or greater than your minimum before generating — the tool will stop and warn you if the range is the wrong way round.
- If duplicates are not allowed, your count cannot be larger than the size of your range, so widen the range or lower the count if you see a warning.
- For a contest or raffle, agree and note your range and entry numbering before you generate, so the winning number can be matched clearly to an entry afterwards.
Frequently Asked Questions
Is this random number generator free to use?
Yes. It is free with no signup required. The numbers are generated in your browser on this page, and your settings are not sent to or stored on a server.
Can the same number appear twice?
Only if you tick Allow duplicates. With that box unticked, every number in a single result set is unique, which is the better choice for raffles and prize draws.
How many numbers can I generate at once?
You can generate from 1 to 1,000 numbers in a single click. If you need more, you can simply run the generator again for another set.
Is this suitable for passwords or security codes?
No. This tool is designed for everyday uses such as games, draws, and sampling. For passwords, use the Password Generator tool instead, and for security-sensitive purposes use a dedicated, purpose-built system.
