I am trying to validate phone number for international format.

^(\+\d{2})*(\d{3})[-. )]*(\d{3})[-. ]*(\d{4})(?: *x(\d+))?\s*$

Valid Numbers should be in +649916123764 format (64 can be replaced by any 2 digits)

But my expression is accepting +649916123764 and 9916123764.

How to control first 3 digits should be in +2 digits followed by 10 numbers?

Remove the `*`: [`^(\+\d{2})(\d{3})[-. )]*(\d{3})[-. ]*(\d{4})(?: *x(\d+))?\s*$`](http://goo.gl/yP9tBx). Is it what you need? – Wiktor Stribiżew Aug 12 '15 at 10:59
Agree with @stribizhev, make it `.` instead `*` specially when it is after `)` and the optional part `[-.` should go with `?` instead `*` – MarmiK Aug 12 '15 at 11:40
@stribizhev: Thank you , understood – Chiranjeevi Aug 12 '15 at 13:48
