Describe the bug
The regexp in use is incorrect for mobile phones in Brazil, and it also has a few bugs as mentioned below:
Bugs
-
Second regexp group is useless as first group is always used
The second group ([6-9]{1}\d{3}\-?\d{4}) is included in the first one (\d{4}\-?\d{4}) -
There is an OR operator missing between the first and second group
-
The two digits that precedes the phone number can be wrapped around parentheses, just like the first 3 digits of the en-US phone number, also it's possible to have a space between the country code and area code, and between the area code and phone number
Examples of phone numbers
With country code and area code
- +55 11 97123-1234
- +55 11 7123-1234
Without country code, with area code in parentheses
- (11) 97123-1234
- (11) 7123-1234
Without country code, with 0 followed by area code
- 015 97123-1234
- 015 7123-1234
Without country code, without 0, with area code
- 11 97123-1234
- 11 7123-1234
Suggested RegExp
I'd suggest the usage of the following regexp as it fixes above issues.
/^((\+?55\ ?[1-9]{2}\ ?)|(0[1-9]{2}\ ?)|(\([1-9]{2}\)\ ?)|([1-9]{2}\ ?))((\d{4}\-?\d{4})|(9[6-9]{1}\d{3}\-?\d{4}))$/
