Question

I want to validate Indian phone numbers as well as mobile numbers. The format of the phone number and mobile number is as follows:

For land Line number

03595-259506
03592 245902
03598245785

For mobile number

9775876662
0 9754845789
0-9778545896
[phone]
91 9857842356
919578965389

I would like the regular expression in one regex. I have tried the following regex but it is not working properly.

{^\+?[0-9-]+$}

Answer 1

Use the following regex

^(\+91[\-\s]?)?[0]?(91)?[789]\d{9}$

This will support the following formats:

1. 8880344456
2. [phone]
3. [phone]
4. [phone]
5. 08880344456
6. 918880344456

Answer 2

All Landline Numbers and Mobile Number

^[\d]{2,4}[- ]?[\d]{3}[- ]?[\d]{3,5}|([0])?(\+\d{1,2}[- ]?)?[789]{1}\d{9}$
