    Scroll down, and enter the Billing Address details for the credit or debit card you'll be using to purchase postage. If you're shipping from an address different from your Billing Address, uncheck the box marked I will be shipping my products from this Billing Address, then specify your Ship From Address (must be a U.S. address).

     

    Can I use a P.O. Box? If you're using a P.O. box, enter the address for your local post office instead. Use the USPS Post Office locator to find the address.

    Scroll further down, and under Payment Information, enter your credit or debit card details.

    Finally, select an Account Type. If you're using the free Account Type, you won't be charged anything until you actually purchase postage for printing labels. Check the box to certify you agree to USPS's and Endicia's terms, then click Create Account.

5. Select your Delivery Services and Packaging Types, then click Save.

Should you need to change your service or package types, click Edit from the zone page. Toggle the ON/OFF switch to enable or disable this method.

 

Did you know? If you're using your own packaging (Parcel), in addition to weight we recommend adding physical dimensions (width, height and depth) for your products. Some real-time shipping providers require these in order to provide your shoppers with an accurate shipping quote during checkout. Typically, the narrowest dimension should be set as the factoring dimension in your physical dimension settings.

Priority Mail, Priority Mail Express, Media Mail, Library Mail70 lbsMaximum length plus girth must not exceed 108 in

International Weight and Dimensional Limits

Some USPS services have different weight limits when delivering internationally. Check the postal service’s listing of Country Price Groups and Weight Limits for more information on specific countries.

USPS’s website provides a Customer’s Guide to Mailing, which has helpful tips on packing and shipping best practices, and even offers free shipping supplies, including boxes, that they will ship to your home or business.

Service Specifics and Rate Calculation

The Postal Service provides a comparison of services on their site, which can help you decide which services are the best fit for you, your product and your customers. Standard Post and Media Mail are not available for international shipping. Generally, for shipments under 6 ounces, First-Class Mail offers the lowest cost solution.

Note that there are some products, like ammunition, that are restricted and that the Postal Service won’t ship.

You can use the Postage Price Calculator to simulate shipments in order to see what each service would cost and get delivery time estimates.

There are several factors that can affect what a shipment will cost:

USPS Real-Time Quotes Common Issues

Symptom: Returned quotes on the storefront don’t match what is displayed on the USPS postage calculator.

Possible causes:

  • Depending on the size of the package, USPS could be assessing a fee using its dimensional weight or balloon weight. Packages that are larger than the length plus girth limits can be charged an oversized rate.

  • If you’re using our older USPS integration, and Package size is not set to “Large”, package dimensions aren’t submitted when requesting a quotes, so if the package has a larger dimensional weight than the actual weight, the returned quote will be too low.

  • Physical dimensions aren't defined for the product. Some real-time shipping providers require these in order to provide your customers with an accurate shipping quote during checkout. Typically, the narrowest dimension should be set as the factoring dimension in your physical dimension settings.

Symptom: Certain services completely fail to return a quote.

Possible causes:

In this instance, it would trigger an error in the store logs when making the quote request. There’s no error reporting on the storefront for this, so there would just be the absence of a First-Class Mail quote.

  • The package might be exceeding the limits for that service. For example, if your product weighs 4 ounces, and a shopper adds 4 of them to the cart, the combined weight is 16 ounces, and would not qualify for First-Class Mail.

  • The origin zip code may be wrong or incomplete. Where possible, use the full nine digit zip code for your origin address ("shipping from" address) in the Shipping Manager.

  • The destination address or country may fall outside of that particular service's specific service area.
