text: i need to find adress for this particular phone number203-887-4564 how can i do this? adress should be in the area of conneticut we're sorry. we did not find a listing for the phone number you entered.  the phone number "(203) 887-4564" is based in new haven, ct and the registered carrier is sprint spectrum l.p. however, due to number portability, some numbers have been transferred to a new service provider other than the registered carrier.  this is from msn white pages.
