Random Number Between 100 and 400

Each press of the randomize key picks one whole number from 100 to 400, counting both 100 and 400. That makes 301 possible results, and every one is equally likely: a 1 in 301 chance, or 0.332%, each time. Results do not remember each other, so getting 400 once makes it no more and no less likely next time.

Good for drawing a winner from a long list, random sampling, or making test data.

The number is picked in your browser, so nothing is sent anywhere and there is nothing to sign up for. Bookmark this page to come back to 100 to 400, or change the bounds above for any other range.

How this Random Number Generator Works

The range starts at 100 to 400; change either bound for a different one.
If you like, add a prefix or suffix, such as a ticket letter or a unit.
Optionally, show the number with leading zeros, eg '0019' instead of '19'.
Press randomize for a new number, and copy it when you have the one you want.
