PIN Length
How to Generate a PIN using the tool?
- Set the PIN length using the slider. The range that can be used is 4 to 20 digits. Default length is 4 digits
- The PIN is automatically generated in the PIN field for the configured length
- You can regenerate new PIN each time by clicking the Generate button or Refresh icon
How Secure is the Generated PIN?
- The PIN generated by this tool is generated locally and not stored anywhere. There is no exchange of data with server for PIN generation or storage.
- This PIN is generated using Pseudo Random Number Generator (PRNG) algorithm. It generates a random number based on computation or a programming algorithm.
- RNG is the most secure method. The higher the number of digits, the more secure it will be
- There are other pin generation techniques such as Hash Function and Salted Hash mainly used for storage, Paraphrase Pin generation based on dictionary and Cryptographically Secure Random Number Generator or CSPRNG that uses a seed from external source such as noise, OS interrupts etc..
- A 4 digit PIN is secure enough for most common usage. With a 4 digit combination, the tool can generate upto 10,000 combination of random numbers ranging from 0000 to 9999
Generate secure random PIN numbers for various applications. Create 4-digit, 6-digit, or custom-length PINs with true randomness. Perfect for security codes, access control, verification codes, and temporary passwords.
How to Use

Tips & Best Practices
Use 6 or more digits for better security
Avoid sequential numbers (1234) or repeated digits (1111)
Don't use birthdays, anniversaries, or obvious dates
Change PINs regularly for sensitive accounts
Never share your PIN with anyone
Use different PINs for different accounts
Memorize PINs instead of writing them down
Frequently Asked Questions on Pin Generators
What is the Random 4 Digit Number Generator all about?
The Random 4 digit Number Generator is a free online tool for users to generate 4 digit codes for their everyday use.
Users can use this generated code to configure and secure their digital sites and physical devices that support pin based entry.
Is the Random 4 Digit Number Generator really free?
Yes, it can be used any number of times without any limits or conditions
Can I generate unlimited numbers?
Yes, you can generate unlimited PINS ranging from 4 digits to 20 digits.
The number of combinations ranges from 10^4 (10 k) to 10^20 (exa)
Are the numbers generated truly random?
This tool uses PRNG (Pseudo Random number Generator) which is program based, all of which typically use a seed based on which the number sequence is generated.
The numbers generated by PRNG are not considered as truly random unlike the TRNGs.
A TRNG or True Random Number Generator uses physical component that relies on signals, noise, vibrations, interrupts, wind, disturbances etc. to produce the randomness.
How many 4 digit PIN combinations are there?
A 4 digit PIN ranges from 0000 to 9999. Each digit can take a value of 0 to 9. This means there can be 10^4 or 10,000 combinations.
A 6 digit PIN will have10^6 which is equal to 1000000 ie a million combination of number
