Instant address list cleaning

At Experian Data Quality, we can instantly clean and correct your address lists. Here's how it works: After you upload your data, we parse the addresses and search the USPS database for your address data. We then score the options and select the top matches. Finally, we update the addresses with the best matches. Using our address list cleaning solution reduces costs on undeliverable mail and undeliverable packages. Why use Experian?

  • We verify your addresses with the most recent USPS data.
  • Each of your addresses are placed in one of four categories, letting you know the addresses' exact status in terms of deliverability.
  • We provide you with delivery point validation (DPV) and footnotes. DPV goes beyond validating whether an address is correctly formatted and confirms whether the address exists in the USPS database. DPV can validate addresses down to the apartment or suite level. The footnotes provide additional clarifying details regarding the address data.
