About 4-digit numbers
Looking for a random 4-digit number? This generator covers all 10,000 values from 0000 to 9999. Use it for PIN-style codes, Singapore/Malaysia 4D practice picks, gift-card shaped IDs, or raffle tickets. Toggle PIN-safe to skip sequences like 1234, repeats like 1111, and birth-year-like values.
Split intent on this page: PIN / code use (try PIN-safe mode), lottery-style digit draws (standard mode matches tools like Singapore 4D), and ID / raffle tickets. Modes change the pool—not just the label.
Common uses
- PIN and lock-code style numbers (not a security product)
- Singapore Pools 4D and Magnum 4D quick-pick practice
- Gift card / voucher style 4-digit codes
- Raffle tickets in the 0000–9999 pool
How many 4-digit combinations exist?

| Standard (leading zeros on) | 10,000 |
| Standard (leading zeros off) | 9,000 |
| No-repeat digits (leading zeros on) | 5,040 |
| PIN-safe | Filters sequences, repeats, and 1900–2099-style years from the no-repeat pool |
FAQ
Q: Does a 4-digit result include leading zeros?
By default yes—so a 4-digit value stays fixed width (for example 0042). Turn off "Allow leading zeros" to force the range 1,000–9,999 instead (9,000 values).
Q: How many 4-digit combinations exist?
With leading zeros: 10,000 (104). Without: 9,000. No-repeat mode (each digit at most once, leading zeros on) has 5,040 values. PIN-safe mode further filters sequences, all-same digits, and birth-year-like 4-digit patterns.
Q: Can I generate a 4-digit PIN that isn’t easy to guess?
PIN-safe keeps digits unique and drops obvious weak patterns: all digits the same (like 1111), straight sequences (like 0123), and—for 4-digit only—year-like values from 1900–2099. This is a convenience filter for practice codes, not a security product.

Did you know
4-digit numbers in the wild
Quick, trustworthy snippets you can actually use—math, odds, and real-world places these lengths show up.
Security
Why simple PINs show up often
Studies of leaked PIN data show sequences like 1234 and 1111 still dominate; random picks spread risk more evenly than birthdays.
Culture
The number four in East Asia
In Mandarin and several other languages, “four” can sound like the word for death, so some people skip 4 in floors, plates, or PINs—purely cultural preference, not math.
Odds
One random guess
Pick a single 4-digit code at random and you have a 1 in 10,000 chance of matching a specific target—easy to say, hard to hit.
Travel
Hotel safes
Room safes usually default to 4 digits because guests can memorize them after one trip and staff can reset them quickly.
Time
Years on a screen
Dates like 2026 are 4-digit years; your brain treats them as labels, but they are the same width as a bank PIN.
