RegEx Pattern: extracting phonenumbers from a text block

I'm trying to get all the phone numbers from a string.

Input string: 

Antoine Smith 911 839 7393 9118582588 91145MAURY Bob Smith

I want to get the three phones numbers: 911 839 7393 9118582588 91145MAURY

The regex I'm using.

[a-zA-Z]*([0-9]( |-)?)?(\(?[0-9]{3}\)?|[0-9]{3})( |-)?([0-9]{3}( |-)?[0-9]{4}|[a-zA-Z0-9]{7})+

However this doesn't work.

If I just put in the phrase : "911 839 7393 9118582588 91145MAURY Bob Smith" then the regex returns the phone numbers.

What regex should I be using?

Great answers guys.

Used: (0-9?)?((?[0-9]{3})?|[0-9]{3})( |-)?([0-9]{3}( |-)?[0-9]{4}|[a-zA-Z0-9]{7})*

Interesting... it becomes more challenging when one considers phone numbers by name. So many permutations are possible considering dashes, dots and parenthasis as delimiters. Here is what I came up with:

((\+\d{1,2}\s)?\(?\d{3}\)?[\s\.\-]?\d{3}[\s\.\-]?\d{4})|(\+?\d{1,2}\s?\(?\-?\d{3}\)?\s?\-?[a-zA-Z0-9]{3,4}[\s\.\-]?[a-zA-Z0-9]{3,5}\b)

It seems to work OK for your example and several popular national numbers like 1-800-FLOWERS and 1 800 BEST-BUY, the latter of which was slightly tricky since the pattern is 4 letters - 3 letters instead of the reverse form.

Hope that helps.

You can use this regex:

(\d{3}\s?\d{3}\s?\d{4})|(\d{5}\w{5})

Working demo

enter image description here

Btw, the regex can be shortened a little to:

((?:\d{3}\s?){2}\d{4})|(\d{5}\w{5})

Assuming that the area code will never be letters and spaces are the only punctuation to account for, this will work \d{3} ?\w{3} ?\w{4}.
