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

Answer 1

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'^[9876]\d{9}$'.
