# Delete Phone Number

> Use the delete_phone_number MCP tool on the DialNexa remote MCP server.

<span data-api-safety-label="destructive"><Badge color="red" size="sm" shape="pill">Destructive</Badge></span>

Releases/deletes one of the organization's phone numbers. This is NOT reversible. Use get\_organization\_phone\_number first to confirm you have the right one. Requires confirm: true — only set this after the user has explicitly approved removing this specific number, never preemptively.

## Parameters

| Name              | Type      | Required | Description                                                                                             |
| ----------------- | --------- | -------- | ------------------------------------------------------------------------------------------------------- |
| `phone_number_id` | `string`  | Yes      | The phone number ID, e.g. phn\_abc123                                                                   |
| `confirm`         | `boolean` | Yes      | Must be true. Set this only after the user has explicitly approved deleting this specific phone number. |

## Before you call

* Connect and initialize the MCP client with OAuth or an API key for the intended workspace.
* Provide the required parameters: `phone_number_id`, `confirm`.
* Set `confirm: true` only after the user approves the exact target and action.

## Example MCP request

Send `tools/call` after your client completes MCP initialization. Replace placeholder values with IDs and inputs from your workspace. For object and array parameters, follow the nested requirements in the parameter description instead of treating an empty value as complete.

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "delete_phone_number",
    "arguments": {
      "phone_number_id": "phn_abc123",
      "confirm": true
    }
  }
}
```

The server returns one text content block. Parse `content[0].text` as JSON when the tool succeeds. See [MCP responses and errors](/docs/mcp-tools/errors) for the full envelope and failure behavior.

## Verify the result

Confirm the response is not marked `isError`. Call [Get Organization Phone Number](/docs/mcp-tools/phone-numbers/get-organization-phone-number) to read the affected resource. Verify that the target is removed or disconnected before reporting completion.

## Retry safety

This tool can remove or disconnect a resource. Confirm the exact target first, and do not retry after an uncertain result until you verify the current state.
