Address Deduplication in the Netherlands
Cleansing your Dutch addresses of duplicates enhances the quality of the data significantly. POSTADRESS GLOBAL arranges a customised solution on your behalf.
Your addresses are standardised before the actual cleansing takes place. The cleansing is carried out via a merge with records of the official postcode directory and a daily updated household database. Duplicate existing entries are recognised, flagged and deleted quickly in a secure environment.
The actual removal of duplicates is carried out by using the usual merge purge process. The data is merged with itself to find possible duplicate records. Data found is flagged to differentiate a primary or head duplicate (which will probably be kept) from a secondary duplicate (which will probably be deleted).
