Ideal Postcodes launches an address cleanse solution to verify, format and enrich your address database

What is Address Cleansing

Address Cleansing is the process of correctly formatting and verifying address records. If your organisation has an incomplete and obsolete customer address database, address experts check each record against authoritative data sources and clean up the database.

The address data is sourced from Royal Mail's Postcode Address File (PAF), including Not Yet Built and Multiple Residence datasets. Rooftop geolocations are provided by Ordnance Survey's AddressBase Core database.


Cleansing your address database ensures your customer data is accurate, up-to-date and compliant.

Increase Database Accuracy

With additional datasets such as UPRNs, Not Yet Built, Multiple Residence and rooftop geolocations, you’ll hold a more precise and detailed view of your customers.

Reduce Costs

Save time and costs of manually fixing your address records by letting us cleanse your database. Our specialists will provide you with a free data report to assess the results of the matched records.

Data Compliant

It is essential that your data is compliant with the data protection principles outlined in the GDPR Regulation. Cleansing your address database will ensure all records are correctly formatted, accurate and up-to-date

Data Quality

  • Validity: All addresses are verified against Royal Mail's Postcode Address File (PAF) and Ordnance Survey's AddressBase Core database. These are two of the most authoritative address databases in the UK. You can rest assured that your address data is accurate and up-to-date.

  • Completeness: If you have missing address details in your database, this will be matched to a valid address and be filled out so you'll hold more complete records.

  • Uniformity: In the UK, there are specific addressing elements that constitute a well-formed address. Keeping this format consistent will ensure your database is correctly structured throughout your database. Our guide on good addressing guidelines outlines the correct UK address formatting.

  • Improvement: You can enhance your address data further by appending UPRNs, rooftop geolocations, Multiple Residence and Not Yet Built datasets.
