# Sender addresses API overview

<Warning>
  **API v2 is entering maintenance mode.** New users should start with API v3 to access our latest features and improved
  performance. Already using v2? Don't worry, your current integration remains fully functional. Read more about
  [maintenance mode](/docs/getting-started/api-version-guide), or check out the [migration guide for API
  v3](/docs/getting-started/migration-guidelines-for-api-v3).
</Warning>

Carriers require sender address information to be present on the shipping label. The **Sender addresses API** allows you to retrieve the sender addresses associated with your Sendcloud account.

## Default sender address

You can have multiple sender addresses associated with your Sendcloud account, but one sender address must always be set as **default** in your account [address information](https://app.sendcloud.com/v2/settings/addresses/sender).

If you choose not to specify a sender address when you use the [Create a parcel or parcels](/api/v2/parcels/create-a-parcel-or-parcels) endpoint, the default sender address will be used.
