Connection guidelines

Before you can start shipping orders through Endicia, you must first connect your Endicia account to Small Parcel Suite from the Small Parcel Settings page.

Once you connect a customer's Endicia account to Small Parcel Suite, you cannot use your primary warehouse account for that customer when shipping with Endicia.

Navigate to the Small Parcel space, then select Settings and choose a customer from the drop-down menu.
In the Carrier Accounts section, click Create.
Using the drop-down menus, specify whether you are setting up a 'Warehouse Account' or 'Customer Account', select the relevant warehouse or customer, choose Endicia, then click Next.
Enter the 'Endicia Account' number, then enter the 'Passphrase' for the Endicia account.

For more information on your passphrase, see About Pass Phrases and Internet Passwords.
For 'Nickname', enter a descriptive name to identify the account.
Click Connect to receive a confirmation message.

Once connected, the carrier account is instantly set up, and your warehouse can start shipping against the account.

If this carrier account is registered in a country that is different from where your 3PL account is located (defined under Admin > Manage Company Info), you must first reach out to Support so they can update this carrier account's home country before you can begin shipping with the account.

We recommend printing 1–2 test shipping labels at least one business day in advance of needing to print labels for active shipments.

If you plan on connecting multiple accounts for a single carrier, please see Connecting Multiple Accounts for the Same Carrier before repeating Steps 1–6 above.

Troubleshooting

Why am I getting an error "full name is required when creating international labels using Stamps or Endicia"?

The USPS require a legitimate first and last name for the ship-from and ship-to recipients of an international shipment. To successfully process your label request, you must enter a valid first and last name in the contact details for the ship-to information and contact Extensiv Support to update your ship-from information if needed.
