Random 3-digit number generator

Q: Does a 3-digit result include leading zeros?

By default yes—so a 3-digit value stays fixed width (for example 042). Turn off "Allow leading zeros" to force the range 100–999 instead (900 values).

Q: How many 3-digit combinations exist?

With leading zeros: 1,000 (10³). Without: 900. No-repeat mode (each digit at most once, leading zeros on) has 720 values. PIN-safe mode further filters sequences, all-same digits, and birth-year-like 4-digit patterns.

Q: What does PIN-safe mode do for 3-digit numbers?

PIN-safe keeps digits unique and drops obvious weak patterns: all digits the same (like 111), straight sequences (like 012), and—for 4-digit only—year-like values from 1900–2099. This is a convenience filter for practice codes, not a security product.

Q: Can I use this as a 3-digit code generator for games or demos?

Yes—leave leading zeros on so codes like 007 stay three characters wide. Standard mode covers every code from 000 to 999; use no-repeat when each digit in the code must be different, or PIN-safe to skip obvious patterns like 123 for practice only (not for real secrets).
