Handled correctly, good quality data produces focused mail that delivers results; Unchecked data with out of date or invalid addresses lowers results as well as wasting material and costs. That’s why Sharp Cat has a technical team to run client data through returns suppression, deduplication and PAF (Postcode Address File) verification as well as options for additional cleaning processes such as proper casing and salutation creation. And if you are buying data through Sharp Cat Geolist, the data is already clean and up to date. Geolist offers the most comprehensive UK address data that we know of and draws from a combination of trusted sources including Royal Mail PAF and Ordnance Survey. Data currency Did you know that in May 2025 there were 32,142,732 actual Delivery Points on PAF? 1,000’s of addresses change every day, because of: New Construction: Homes, businesses, and other structures are constantly being built Property Modifications: Renovations, such as converting houses into flats Demolitions: Removal of properties permanently Operational Needs and Postcode Changes: Royal Mail makes changes to optimise its internal mail sorting and delivery processes and occasionally, changes to postcode boundaries can also lead to adjustments in delivery points As well as this the UK is a very mobile population, an estimated 5,000 people change address per day and on top of this over 20,000 businesses cease trading each year.
