Multiple Residence

Did you know that around 750,000 address records are additional to the Royal Mail Postcode Address File (PAF)?

Why are so many address records missing?

The Royal Mail PAF contains almost 30 million 'front door' letterbox addresses in the UK. But behind around 182,000 of those front doors are 733,000 residences or organisational units which do not appear on PAF. This is because those additional addresses do not each have their own Royal Mail accessible letterbox. Now, these extra addresses are available from AFD Software.

What kind of properties are affected?

Student accommodation, apartments and business premises are all present on the Multiple Residence file. The number of separate addresses behind the single accessible letterbox can be as few as one additional record – or as many as 1,000!

Why does it matter to you?

This situation can have serious consequences in many sectors including retail, financial, insurance and distribution. For example, if you capture an address as 30 Park Place, LS1 2SP, you would not be aware that this building containing 63 residences only has one address on PAF. It's easy to see how fraud can occur. A courier delivers a TV signed for by a person who opens the front door – and the intended recipient denies receiving it. A credit card is delivered with the sender not realising that this is a 'high risk' property.

What can you do about it?

Thankfully Royal Mail has put considerable resources into building a Multiple Residence file which aims to cover these 'missing' or 'hidden' addresses. If you would like to access them please contact us now to find out how.
