I have a regular expression that can find US Phone Numbers containing various formatting as shown:
xxx xxx xxxx
I'm trying to adjust the regular expression, so that it only finds phone numbers MISSING the area code. Therefore the phone number in sample text like this would be flagged:
This is a test phone number missing area code: 123-4567.
The following phone number would not be flagged:
This is a test phone number containing area code: (123) 123-4567.
Thanks in advance.
