FAQ

Random 4-Digit Number Generator: your questions answered

How do I generate a random 4-digit number?

Press Generate. The tool picks a whole number from 1,000 to 9,999, so it always has exactly 4 digits, with every one of those 9,000 numbers equally likely.

Can a 4-digit number start with zero?

Switch on “Allow leading zeros” to include 0000 to 0999, like a real PIN. Leave it off to get a number from 1000 to 9999.

How many 4-digit numbers are there?

There are 9,000 numbers with exactly 4 digits when the first digit cannot be zero, or 10,000 if leading zeros are allowed (from 0000 to 9999).

Can I get several 4-digit numbers at once without repeats?

Yes. Set “How many”, and switch on “No repeats” in the full generator on the home page if you need every number to be different.

Are the digits really random, and are they stored?

They come from your browser’s cryptographically secure random generator and are created on your device. They are never sent to us and never stored.
