Introduction

Fenix’s Address Validation and Standardization API (FAVS) corrects errors in street addresses including abbreviations and missing information, and supplies standard 5 digit zip code and ZIP+4 Codes. By eliminating address errors, retailers would improve the overall shipping process and reduce unnecessary shipping spend on returns and for address corrections.

Fenix Address Validation and Standardization API (FAVS)

With FAVS API, you can improve delivery predictability and reduce delivery failures, thereby providing improved customer experience. You do this by catching incorrect addresses and obtaining better awareness of address characteristics.

Features

Following are some of the features of FAVS

1. The API is Real Time and is able to validate addresses in real-time, allowing users to receive instant feedback on whether an address is valid or not

2. The API can detect if the address is a residential or business address, a deliverable address, a central delivery address , vacant address or a military vacant address

3. The API automatically corrects contents of address such as misspellings, no city name, incorrect zip code and it also formats the address compatible with USPS address standards

4. Auto populates the county code when applicable

5. Detects if the apartment number is missing from the address

6. Auto suggests a better address if available

API Details

FAVS API is a REST based API that takes the US address as the input and returns the corrected or proposed address as per validation.

Below is the sample Fenix Address Validation request and response.

Flow

   Retailers can integrate with Fenix Address Validation at three important places in the order flow. 

...

Retailers can call FAVS API at the time of label printing to make sure the label is printed for the correct address. Printing labels for incorrect addresses can lead to delivery delays, additional shipping spend to correct addresses and in the worst case, return the package back to the warehouse.
