[CH208000] CH208000 – How to do a compliance check: Returned Letter Service (RLS) – action on receipt of an RLS correspondence
Where correspondence is returned to us, the address it was sent to can be referred to as:
•a ‘Returned Letter Service’ (RLS) address, which is how it is shown on the majority of our IT systems, or
•a ‘Dead Letter Office’ (DLO) address, which is how it is shown on the National Insurance and PAYE systems.
On this page we use ‘RLS’ to refer to both of these.
A notice or form may be returned RLS for different reasons. For example, the person may have genuinely forgotten to tell us that they have changed address, or they may have returned the letter marked ‘gone away’, hoping that we will abandon our compliance check.
