How Do You Generate a Random Number with a Set Number of Digits?
To generate a number with an exact number of digits, type the length in Digits, such as 4 or 6, choose how many numbers you want and click Generate numbers. With First digit set to Never 0, a 4-digit number will always be between 1000 and 9999. Choose Can be 0 for codes like 0482.
Fixed-length numbers are useful for codes, references, test data and games. Developers use them for sample IDs, testers for form fields, teachers for place-value practice, and anyone who needs a random 3, 4, 5 or 6 digit number in a hurry. Grouping long numbers in 3s or 4s makes them easier to read.
Numbers are made on your own device. Every result uses your browser’s secure random number generator (crypto.getRandomValues), and nothing you type is sent to Teasoft.
