how can I handle no spaces in phone number case for this regex

Question

I have a regex that parses out the three parts of a phone number input - but it doesn't handle some cases like 5555555555 or 555-2342341

^(?:\+?1?[-.\s]?)(\d{3})([-.\s])(\d{3})\2(\d{4})$

how can I modify it so it handles these cases as well?

Just added some more 0-1 quantifiers for the test cases you were missing:

^(?:\+?1?[-.\s]?)\(?(\d{3})\)?([-.\s])?(\d{3})([-.\s])?(\d{4})$
