4-Digit PIN Generator
Generate a random 4-digit PIN from 0000 to 9999, created instantly in your browser.
How many combinations does a 4-digit PIN have?
A 4-digit PIN has exactly 10,000 possible combinations (104), from 0000 to 9999. Because the range is small, randomness matters enormously: predictable choices like 1234, 0000 or a birth year cover a disproportionate share of real-world PINs and are the first values attackers try.
Need more combinations?
Where the system allows it, a 6-digit PIN (1,000,000 combinations) or an 8-digit PIN (100,000,000 combinations) is meaningfully harder to guess.
Frequently asked questions
How many combinations does a 4-digit PIN have?
10,000 — every value from 0000 to 9999.
Is a 4-digit PIN secure?
A random 4-digit PIN is far safer than a chosen one, but where the system allows it, a 6- or 8-digit PIN offers more combinations.
Does this generator store my PIN?
No. The PIN is generated locally in your browser and never transmitted or saved.
