# Check phone carriers before a CRM import

**Use case:** 

Preview carrier and line-type output using two fictional numbers. This synthetic demo makes no live lookup. For real CRM contacts, choose own-key mode, add your LookupLab key and replace the numbers. Export results to CSV or JSON. LookupLab credits and Apify platform usage apply to live checks.

## Input

```json
{
  "mode": "demo",
  "numbers": [
    "+12025550123",
    "+442079460123"
  ]
}
```

## Output

```json
{
  "row": {
    "label": "Row",
    "format": "number"
  },
  "input": {
    "label": "Input",
    "format": "text"
  },
  "status": {
    "label": "Status",

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/pale_firewood/lookuplab-phone-list-checker.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
