Our system validates your address via the same USPS database that's used by UPS & FedEx. And as you might imagine, we can't purchase shipping labels or insurance for invalid addresses.


If your address won't validate, there's a good chance it's for one of the following reasons:

  • new construction
  • address not registered with USPS
  • addressed marked as "vacant" by USPS

So how do you fix this? You're going to want to contact the nearest USPS Address Management Systems branch, which you can lookup via this link. Once reported, it usually takes USPS 1-2 weeks to resolve most issues. In the meantime, you might try shipping to a neighbor with a valid address.
