A few of the 40 quality checks applied to each record every month
  • Each address is run against the latest Royal Mail Postcode Address File (PAF) and corrections made where necessary.
  • The lengths of Address Lines 1 and 2 are balanced to give a professional appearance on the envelope.
  • The data in the telephone number field is formatted correctly with the area code separated from the number.
  • Detailed business classifications are matched to an SIC code, which is then added to the record to improve selection capability. We also add our own unique business classification code, which is more comprehensive than SIC codes or directory coding systems.
  • The entire database is de-duplicated to in-house standards, which have been developed from years of database experience. This ensures the retention of the maximum number of records with virtually no duplicate entries.
  • A unique identification number is generated for each record.
  • The entire database is checked against the Telephone Preference and Corporate Telephone Preference Registers on a daily basis.
