# Get Phone Number Details
> Fetch one phone number by ID.
Read only
**Recommended.** This endpoint is part of the public `/v1` API reference and is the supported path for new integrations. See the [migration guide](/docs/api-reference/v1/migrating-to-v1) for versioning guidance.
Returns the full record for a single purchased phone number: the E.164 `phone_number`, the `country_code`, the `type` (local, toll-free, or mobile), the monthly rental cost, the supported `capabilities` (voice, SMS where available), the display `nickname`, the currently assigned `inbound_agent_id`, and the purchase timestamp.
## When to use this
* **Number management UIs**: render the per-number detail view in a phone-number management page.
* **Routing audits**: verify which agent is currently handling inbound calls on a specific number before making changes.
* **Cost attribution**: pull `monthly_cost_usd` to attribute telephony spend per workspace or per use case in internal reports.
* **Compliance reviews**: confirm the number's country and capabilities match the use case it is being used for.
For the entire portfolio of numbers on the workspace, use [List Phone Numbers](/docs/api-reference/v1/phone-numbers/list).
## Path parameters
| Parameter | Description |
| --------- | ---------------------------------------------------- |
| `id` | The phone number ID, for example `phn_f7w2kx5mb9qz`. |
## Errors
* `404 Not Found` is returned when the number does not exist on this workspace.
* `403 Forbidden` is returned when the API key cannot read phone number records.
