Question

I’ve been looking at many regexp validations for phone numbers but I could not find one that allows only 10 digits and not to start with 0 or 1, obviously only numbers

I found this one

^((\+)?[1-9]{1,2})?([-\s\.])?((\(\d{1,4}\))|\d{1,4})(([-\s\.])?[0-9]{1,12}){1,2}$

but is to allowing for what I need.

I am using this expression in javascript and I can use the max 10 digits there.

any ideas?

Answer 1

10 digits, not starting with 0 or 1:

^[2-9]\d{9}$

Quick explanation:

^       start of string
[2-9]   matches only digits 2 to 9 (thus excluding 0 and 1 as requested)
\d{9}   any 9 digits
$       end of string
