The first place to start customizing your shipping options via WooCommerce shipping zones is here. You can construct as many zones as you like, and each zone can be as large or small geographically according to your demand. You can, for instance, create a shipping zone for the entire United States, a zone for one or more states, or even a single zip code.

Note: In a single shipping zone, you can designate numerous shipping methods. You must specify USPS as one of the zone’s shipping methods if you plan to offer USPS shipping.

In terms of Shipping options, this section refers to specific settings as below:

Step 5: Setting up the shipping classes

If your products differ substantially in weight, size, or packaging, creating WooCommerce shipping classes can be quite handy.

For example, suppose you have flat rate delivery arranged for all of your products but one or two that are significantly bigger and will charge you more to deliver. In that case, you may establish and apply a “bulky” shipping class to those products and command a higher flat-rate.

Step 6: Configure USPS settings

Setting Up WooCommerce USPS Shipping Rates

When the USPS shipping method to a shipping zone is added, configuring the USPS settings is what you need to do. Pick out the shipping zone you want to edit > click Edit under USPS in the Shipping Method section.

Next, you will see Method Title, Origin Postcode, Tax Status, Offer Rates, and Fallback

  • Method Title - the name of the shipping method that is visible to customers at checkout

  • Origin Postcode - the postcode from which the items will be shipped and it is a required field

  • Tax Status - you should check with federal and state regulations if you think your items are non-taxable

  • Offer Rates – choose whether to offer the customer only the cheapest rate or all returned rate options

  • Fallback – if no rates are received from the API, submit a fallback shipping cost (optional). If USPS somehow does not respond matching pricing, the purchaser might check out. Do not use a dollar sign when utilizing this selection; merely enter the amount.

Now you must choose between using only USPS Flat Rate Boxes and Envelopes, USPS API rates, or both. If you enable Flat Rates, the four alternatives listed below will appear.

flat rates

In particular:

  • Flat Rate Boxes and Envelopes — Select this option to use USPS Flat Rate services for shipment. The consumer is given a single rate after the items are packaged into the boxes/envelopes

  • Express Flat Rate Title — Give the flat express rate a custom name

  • Priority Flat Rate Title — Give the priority flat rate a custom name

  • Additional Fee – Enter a figure or a percentage for an additional fee per box, excluding tax. Alternatively, you may leave the field blank to deactivate it.

Setting Up WooCommerce USPS API Rates

If you choose to use USPS API rates, the WooCommerce Shipping Method plugin will automatically apply standard USPS service rates.

Select Enable API Rates by choosing the box. Your screen will appear like this once you have clicked the button.

api rates

API Rates — Use the USPS API to enable non-flat rates. By default, all services are available; alternatively, you can pick and choose from the different shipping services listed below. You can make the following changes:

Enable API Rates - Allow non-flat rate services

Original Postcode - Postcode from where you ship. It’s forwarded to the USPS API

Shipping rates - Retail rates are the usual costs, while commercial rates are reduced. Set it to “Commercial rates” if you want those rates to match the ones you obtain when printing labels with WooCommerce Shipping. When you print using WooCommerce Shipping, you are automatically eligible for Commercial rates.

Packing Method for Parcels

Upon choosing a Parcel Packing Method, you have three alternatives: pack items individually (default), **pack into boxes with weight and dimensions (suggested), or **weight-based.
