# Using ShipStation Carriers in a Sub Account

ShipStation Carriers are carriers that are automatically available to ShipStation API accounts based in the US, Canada, the UK, Australia, and Germany. These carriers have pre-negotiate contracts providing services that your partner sub-accounts can start shipping with in just a few minutes.

## Activate ShipStation Carriers

Before the sub-account can start shipping with services from ShipStation Carriers, the sub-account must first activate ShipStation Carriers during their [onboarding process](/apis/shipengine/docs/carriers/setup). “Activating” simply requires adding the payment method that will be used to purchase the labels and agreeing to the carriers’ terms and conditions.

### Adding Funds

During or after onboarding, the sub-account must also [add funds to their account balance](/apis/shipengine/docs/carriers/add-funds). Once the sub-account has activated ShipStation Carriers and added funds to their balance, they can start purchasing labels for these services.

## Available Carriers

The carriers available to any sub-account will depend on the `origin_country_code` set for the account when it’s [created](/apis/shipengine/docs/partners/accounts/create). For example, accounts with `origin_country_code` set to GB will only have access to the UK ShipStation carriers.

| Country Code | Available ShipStation Carriers |
|  --- | --- |
| US | USPS (via Stamps.com), UPS (if approved by UPS) |
| CA | Canada Post, GlobalPost |
| GB | DPD UK, EVRi, GlobalPost, Parcelforce, Yodel |
| AU | Aramex Australia, CouriersPlease, Sendle |
| DE | DPD Germany |


## Supporting Your Sub-Accounts

To support your sub-accounts using ShipStation Carriers, you need to be able to capture all the required data for the endpoints your sub-accounts will be using with the carriers they ship with and send that data via the ShipStation API.
