Why is my address not verified? Sometimes when you enter your property address, you may get this popup error: "We couldn't validate your address. This may result in decreased visibility and reliability for your advertisement." 1 First, check for misspellings in your address. 2 Next, make sure the zip code and state are correct. 3 Check to make sure the address number is correct. 4 Try to find your address using the USPS Address Tool: https://tools.usps.com/go/ZipLookupAction!input.action?mode=0&refresh=true (this is what we use to verify addresses). You might find that USPS uses a slight variation of your address. If you're still unable to verify your address, contact Support and we'll be happy to help you!
