The below shows the number of addresses on Royal Mail’s Postcode Address File (PAF) that have either been added, amended or deleted from the UK PAF universe of circa. 32 million addresses.  The PAF file is the UK’s definitive address file showing all known deliverable properties within the UK.  The PAF file excludes Not Yet Built (NYB) and Multi Residency (MRES) addresses.  MRES addresses are classified as addresses that are located “behind” a PAF address and not physicaly accessible to Royal Mail’s Post Persons (their common letters box, featured on PAF is therefore the delivery point for these MRES addresses):
