Tell us more! Is your example really what your data look like or do the phone numbers look like typical phone numbers (and, if so, how many different types are there? e.g. 555-555-5555, 1-555-555-5555, (555) 555-5555), is the @ symbol used in any other fields other than email addresses?

Or are you only asking regarding the specifics you initially posted?

I can only guess at the variable lengths you might really need, but I think you are looking for something like:

data have;

informat attr $80.;

input id attr &;

cards;

1 555-555-5555

1 (555) 555-5555

1 80 Here Street, Somewhere

2 1-555-555-5555

2 myname@notmyprovider.com

2 myname@myprovider.com

3 90 There Road, Elsewhere

3 Apt 1A

4 notmyname@notmyprovider.com

;

data want (keep=email address phone);

set have;

retain pattern address phone email;

length address phone email $80;

by id;

if _n_ = 1 then pattern = prxparse("/\d\d\d-\d{4}/");

if first.id then do;

call missing(address);

call missing(email);

call missing(phone);

end;

if PRXMATCH(pattern,attr) then phone=catx(',',phone,attr);

else if index(attr,"@") then email=catx(',',email,attr);

else address=catx(',',address,attr);

if last.id then output;

run;
