Regular expresion for 000 to 999

Question

I try to create a regular expression that allow me to filter values that start with these ranges: 000 to 999

I try with this ^[001-999]{3}$ but it doesn't work well with ranges to 000 to 099

Thanks for your help

What happens with this a bit too loose? `^[0-9]{3}$` should be simpler. — user3783243, Jul 01 '22 at 15:53

This should work for you:

^\d{1,3}$

Here's a visualization to explain what this pattern is doing.

If you only want exactly three digits, use {3} instead of {1,3} (which will also allow 1 or 2 digits): ^\d{3}$

If your regex engine does not support \d, use [0-9] instead: ^[0-9]{3}$

Worth reading this answer for a much more comprehensive discussion of `\d` vs. `[0-9]`: https://stackoverflow.com/questions/6479423/does-d-in-regex-mean-a-digit – Donut Jul 01 '22 at 15:59
