Address Verification FAQs

Why is address verification important?

Inaccurate addresses can lead to failed deliveries, payment fraud, and wasted resources. Address verification helps ensure your data is accurate and reliable.​

How does WinPure verify addresses?

WinPure employs a three-pronged approach to address verification. First, it compares addresses to trusted databases of verified locations. Second, it standardizes the format of the address to ensure accurate matching. Finally, it uses official government databases of 250+ countries to verify and validate address data.

What types of addresses can WinPure verify?

WinPure can verify residential and commercial addresses across a wide range of countries. We can handle variations in address formats to ensure global reach.​

What's the difference between address verification and address standardization?

Address verification confirms if an address exists and can receive mail. Address standardization, on the other hand, focuses on formatting the address consistently according to specific postal guidelines. While verification ensures accuracy, standardization ensures readability and proper mail delivery.

WinPure’s address verification software helps improve delivery success rates, reduce fraud risks, and streamline customer onboarding. It also saves you time and money by preventing errors.​
