Shouldn’t this put the SPAN markers outside the phone number, not inside?

String aParagraph = "start 201-555-1212 more (301)-777-1212 again (401) 888-1212 end";
String phoneRegEx = "\\b(\\(?[1-9]{1}[0-9]{2}\\)?[- ]?[1-9]{1}[0-9]{2}-[0-9]{4})\\b";
String replaceWith = "<span>$1</span>";

aParagraph = aParagraph.replaceAll(phoneRegEx , replaceWith);

    A word boundary, \b, matches a boundary of \w+. You can just remove them:

    String aParagraph = "start 201-555-1212 more (301)-777-1212 again (401) 888-1212 end";
String phoneRegEx = "(\\(?[1-9]{1}[0-9]{2}\\)?[- ]?[1-9]{1}[0-9]{2}-[0-9]{4})";
String replaceWith = "<span>$1</span>";

aParagraph = aParagraph.replaceAll(phoneRegEx, replaceWith);
