Generate a Short Number

Sometimes the whole point of the task is that the number is small - a PIN, a code, a combination, a two-digit answer. Short numbers live in ranges most people can read at a glance, and their length is part of their meaning: a 4-digit PIN and a 7-digit phone number are different kinds of objects even when their ranges overlap.

Generate a Short Number makes numbers with exactly the digit count you choose, 1 to 10. Control the allowed digits, the leading-zero rule and whether repeats are permitted - then batch-generate up to 1000 with copy and download. Numbers that match the spec, exactly.

• Length control: Exactly 1 to 10 digits, your choice.
• Digit pool control: Full 0-9 or a restricted subset.
• Leading zero rule: Clamp or allow 0 in first position.
• Repeat control: Distinct digits or full randomness.
• Up to 1000 numbers: Batch generation in one run.
• Copy or download: Export one per line.

1. Choose the length - 1 to 10 digits.
2. Choose the digit pool - 0-9 or any subset such as 1-9.
3. Set the rules - leading zero allowed? repeats allowed?
4. Set the count - up to 1000.
5. Generate - and read the short numbers.

1. Length 4, digits 0-9, no repeats: a 4-digit "combination" like 7429 - PIN-style.

2. Length 2, digits 1-9, repeats allowed: two-digit numbers like 57 and 88.

3. Length 1, digits 0-9: single digits 3, 7, 0 ... - the simplest possible number.

4. Length 5, digits 1-9 only, no leading zero rule needed: five-digit codes.

5. Length 10, digits 0-9, no leading zero: full ten-digit values up to 9,999,999,999.

• Spec-exact length: The digit count is the point, and it is guaranteed.
• Pool shaping: Restricted digits produce phone-style and binary-style codes.
• Combination mode: No repeats yields distinct-digit numbers on demand.
• Batch output: Hundreds of short numbers at once.
• Copy or download: The list exports one per line.
• Private and free: Everything runs in the browser; nothing is uploaded or logged.
