For land Line number

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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
