Javascript regex: get all numbers having between 2 and 6 digits but not 5

I would like to write a regex that check if the input string is a number between 2 and 6 digits but not 5. Obviously, I can do something like:

^[0-9]{2,4}$|^[0-9]{6}$

but I was hoping for more succinct notation.

This is JavaScript regex. Do you think there is a shorter answer?

Many thanks!

A more-succint version of the same logic:

^(\d{2,4}|\d{6})$

^(?!.{5}$)\d{2,6}$

Try this.See demo.

You can use this:

^(\d{2,3}|\d{4}(\d{2})?)$
