One of the Shipwire company directives is to provide a logistics and fulfillment platform that guarantees the shipment of your order in a timely and accurate manner. When it comes to accuracy in shipping, one of the big requirements is to get the right address on the package. The cost of getting the address wrong ranges from horrible (lost business and angry buyers) to the less horrible (address correction charges on packages). And it is usually avoidable – here is how Shipwire avoids it.
Avoiding incorrect addresses starts before the order ever gets processed for shipment. One of the first steps in our order routing logic is to review the shipping address to ensure it is correct and conforms to the published guidelines of the carriers. We integrate with a lot of carriers – over 12.
For U.S. orders this means the address conforms to comprehensive USPS addressing standards. Shipments that comply with the USPS standards have the highest probability of being delivered – keeping your buyers happy (and our merchants).
Shipwire also assures that the carrier being selected can deliver to the address given. For example, confirming you are not trying to ship to a U.S. Post Office Box via UPS.
We wanted to expose some of our address verification and order routing logic because if you use Shipwire you benefit from it, and may not even realize what it is or how it works.
How Address Verification works:
The Shipwire servers first perform detailed address verification to assure the address given is valid. For example:
- The city being shipped to should have a ZIP code that matches.
- The street name should exist in that city.
- The street number should be valid within a certain range.
USPS maintains an extensive database that cross-references address information making this check possible. USPS has also has developed standards regarding how an address is written. After verification the ship-to address is rewritten to conform to the USPS Postal Addressing standards. You may have noticed that on occasion the address typed into the Shipwire interface might come out looking a bit different than what was originally entered. Shipwire then does a final check to assure that the carriers available to use for shipment can ship to that address.
