# Get audience membership

`GET /v1/audiences/{audience_id}/membership`

Returns the exact number of audience members at the source evaluation instant, including contacts without email and unsubscribed contacts. Membership is absent when the count is unavailable; an empty audience has total zero. For daily observations, use [Get audience membership statistics](/docs/api/reference/get-audience-membership-statistics).

Returns 421 when the workspace's organization is served from a different region from the API host. Retry against that workspace's regional host.

## Code samples

}
```
