[regex] Regular Expression Validation For Indian Phone Number and Mobile number

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
+91 9456211568
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-]+$}

For both mobile & fixed numbers: (?:\s+|)((0|(?:(\+|)91))(?:\s|-)*(?:(?:\d(?:\s|-)*\d{9})|(?:\d{2}(?:\s|-)*\d{8})|(?:\d{3}(?:\s|-)*\d{7}))|\d{10})(?:\s+|)

Explaination:

(?:\s+|)                    // leading spaces
((0|(?:(\+|)91))            // prefixed 0, 91 or +91
(?:\s|-)*                   // connecting space or dash (-)
(?:(?:\d(?:\s|-)*\d{9})|    // 1 digit STD code & number with connecting space or dash
(?:\d{2}(?:\s|-)*\d{8})|    // 2 digit STD code & number with connecting space or dash
(?:\d{3}(?:\s|-)*\d{7})|    // 3 digit STD code & number with connecting space or dash
\d{10})                     // plain 10 digit number
(?:\s+|)                    // trailing spaces

I've tested it on following text

9775876662
0 9754845789
0-9778545896
+91 9456211568
91 9857842356
919578965389

0359-2595065
0352 2459025
03598245785
07912345678
01123456789

you can implement following regex regex = '^[6-9][0-9]{9}$'

All mobile numbers in India start with 9, 8, 7 or 6. Now, there is a chance that you are not bothering about the prefixes (+91 or 0). If this is your scenario, then you can take the help from the website regextester.com or you can use r'^(+91[-\s]?)?[0]?(91)?[789]\d{9}$'

And if you want to validate the Phone number with prefixes(+91 or 0) then use : r'^[6-9]\d{9}$'.

This works really fine:

\+?\d[\d -]{8,12}\d

Matches:

03598245785
9775876662
0 9754845789
0-9778545896
+91 9456211568
91 9857842356
919578965389
987-98723-9898
+91 98780 98802
06421223054
9934-05-4851
WAQU9876567892
ABCD9876541212
98723-98765

Does NOT match:

2343
234-8700
1 234 765

Use the following regex

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

This will support the following formats:

1. 8880344456
2. +918880344456
3. +91 8880344456
4. +91-8880344456
5. 08880344456
6. 918880344456

var phonereg = /^(\+\d{1,3}[- ]?)?\d{10}$/;

All Landline Numbers and Mobile Number

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

You can use regular expression like this.

/^[(]+\ ++\d{2}[)]+[^0]+\d{9}/

I use the following for one of my python project

Regex

(\+91)?(-)?\s*?(91)?\s*?(\d{3})-?\s*?(\d{3})-?\s*?(\d{4})

Python usage

re.search(re.compile(r'(\+91)?(-)?\s*?(91)?\s*?(\d{3})-?\s*?(\d{3})-?\s*?(\d{4})'), text_to_search).group()

Explanation

(\+91)? // optionally match '+91'
(91)?   // optionally match '91'
-?      // optionally match '-'
\s*?    // optionally match whitespace
(\d{3}) // compulsory match 3 digits
(\d{4}) // compulsory match 4 digits

Tested & works for

9992223333
+91 9992223333
91 9992223333
91999 222 3333
+91999 222 3333
+91 999-222-3333
+91 999 222 3333
91 999 222 3333
999 222 3333
+919992223333

For Indian Mobile Numbers

Regular Expression to validate 11 or 12 (starting with 0 or 91) digit number

String regx = "(0/91)?[7-9][0-9]{9}";

String mobileNumber = "09756432848";

check 

if(mobileNumber.matches(regx)){
   "VALID MOBILE NUMBER"
}else{
   "INVALID MOBILE NUMBER"
}

You can check for 10 digit mobile number by removing "(0/91)?" from the regular expression i.e. regx

You Can Use Regex Like This:

   ^[0-9\-\(\)\, ]+$
