  • Number of addresses that can be corrected 
  • Number of duplicates 
  • Number of invalid addresses 
  • Number of addresses that cannot be corrected

We will send you a detailed quotation for the updated and corrected data based on the analysis. You can decide whether or not you want Swiss Post to clean the erroneous data at the quoted price.
