If you're looking to save time and money, look no further than the UPS Address Validation API. This little known, yet very useful application of the Internet allows you to validate addresses and reduce the number of failed deliveries.
The Address Validation API is a great tool for reducing administrative costs and improving customer service. It can help you validate shipping addresses, standardize addresses for mailing, and improve the customer experience.
There are two main endpoints of the UPS Address Validation API. The first is the simple "validate address" endpoint. This only accepts one shipping address at a time. While it does the job, it's not as fast as other methods.
The second endpoint is the more complex "validate street level address". As its name implies, this endpoint takes a street level address and checks it against the USPS database.
The API can also be used to suggest valid street level addresses to the customer. However, it only works for US addresses.
You should be able to verify a street level address in less than a second, assuming you have a working Internet connection. Of course, if you haven't set up a UPS account, you'll need to do so before getting started.
One of the major drawbacks of the UPS Address Validation API is that it doesn't offer a comprehensive address data intelligence suite. Even the best addresses can still have misspellings or incorrect address elements.
Not only is it hard to implement an address validation API, but it can take months to develop
