lynsey_m:Does anyone know if its possible to reopen accounts that you have closed?
If you have closed the account and its settled per their notification of CRAs then i think they would likely need to re-search your profile and score you again to re-open it. Unless it was an account with a great rate or O/D limit or something, you'd be better off getting a new account with (possibly) better offers.
If you mean dormant then i would deffer to what twee said which seems to be from experience and sounds pretty reasonable to me.
