Woocommerce USPS Address Verification API


This plugin is using USPS API to verify the address customer entered on woocommerce checkout page, without disturbing the customer and blocking payment.
If USPS API can correct and standardize the address it does just that, if not then it puts the order ON-HOLD and sends an email to the admin
that order is waiting for manual inspection after the paypal order is processed.
For now it only works with PayPal. If you need with some other payment gateway contact me I’ll develop it for you.

We were getting 1 mistake out of 20 orders. What this plugin does is simple. It takes the address written like this:

205 bagwel ave (bagwel is spelled bagwell, I intentionally made a mistake)
nutter fort
ZIP: 26301

and converts it to:


It standardizes all addresses and fixes minor problems such as typos, or even a wrong zip code if possible.

Plugin is using USPS API. You must register on USPS web site to use this, here:

And in plugin settings you just type in your username and email on which you wish notifications.
