Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## ⚡ Fast WhatsApp Number Validator — Bulk Phone Check & List Cleanup **Clean and validate any phone list before you launch a WhatsApp or SMS campaign — thousands of numbers in seconds.** Paste numbers in bulk and get back, for each one: whether it's a **valid** number, its **E.164** format, **country**, **region**, **carrier**, **line type** (mobile / landline / VoIP), time zones, and a **WhatsApp-ready** flag — so you stop wasting sends on landlines, typos and dead numbers. > ✅ **100% offline — no login, no QR scan, no proxy, no API keys, no bans.** > Built on Google's libphonenumber, the same engine carriers use. It can't be > blocked and it won't silently break. > _Also known as: phone number validator, phone list cleaner, WhatsApp number > checker, bulk phone verifier, mobile vs landline checker._ --- ### ⚡ Quick start ```json { "phoneNumbers": ["+14155552671", "+442071838750", "+5511991234567"], "defaultCountry": "US" } ```` Each number comes back as one clean record. *** ### 🎯 Why this matters WhatsApp and SMS only work on **valid mobile** numbers. A raw list is full of landlines, mistypes, wrong country codes and dead entries. Sending to those: - wastes your WhatsApp Business message allowance and sender reputation, - inflates costs on per-message platforms, - and can get your number flagged for high failure rates. Run your list through this first, drop everything that isn't a valid mobile, and only then spend on outreach. *** ### 📦 What you get per number | Field | Description | |---|---| | `valid` | Is it a real, dialable number | | `e164` | Normalised `+` (the format every API wants) | | `international` / `national` | Human-readable formats | | `country` / `regionCode` | e.g. `United States` / `US` | | `location` | City / area description when available | | `carrier` | Mobile carrier name when known (Claro, Airtel, JT …) | | `lineType` | `mobile`, `landline`, `fixed-or-mobile`, `voip`, `toll-free` … | | `timezones` | Time zones for the number (great for send-time targeting) | | `whatsappCapable` | `true` for valid mobile numbers that can hold a WhatsApp account | *** ### ⚙️ Input parameters | Field | Type | Default | Description | |---|---|---|---| | `phoneNumbers` | array | — | Numbers to validate (one per line) | | `numbersText` | string | — | Optional: paste a whole list / spreadsheet column at once (merged & de-duplicated) | | `defaultCountry` | string | `US` | ISO region for numbers without a leading `+` | | `onlyValid` | bool | `false` | Return only valid numbers (clean list) | | `onlyWhatsappCapable` | bool | `false` | Return only valid mobile numbers | | `exportFormat` | enum | `default` | `default` / `csv` / `both` | *** ### 📤 Output example ```json { "input": "+5511991234567", "valid": true, "e164": "+5511991234567", "international": "+55 11 99123-4567", "country": "Brazil", "regionCode": "BR", "carrier": "Claro", "lineType": "mobile", "timezones": ["America/Sao_Paulo"], "whatsappCapable": true } ``` Set `"exportFormat": "csv"` for HubSpot / Excel-friendly columns. *** ### 💡 Use cases - **Pre-campaign list cleaning** — drop landlines, typos and invalid numbers before a WhatsApp/SMS blast. - **Cut messaging costs** — only keep numbers that can actually receive messages. - **CRM hygiene** — normalise every number to E.164 and tag carrier / country. - **Lead enrichment** — append country, region, carrier and line type to a contact list. - **Send-time targeting** — use the time zone to message at the right local hour. *** ### 💰 Pricing **$1.5 / 1,000 results** ($0.0015 per number). You pay per number returned — use `onlyValid` / `onlyWhatsappCapable` to return (and pay for) just the numbers you care about. *** ### ❓ FAQ **Does `whatsappCapable` mean the number is on WhatsApp?** It means the number *can* hold a WhatsApp account — it's a valid mobile line. WhatsApp has no public registration API, and bulk-checking through an unofficial logged-in session gets accounts **banned**, so this Actor stays 100% reliable by validating offline. Use `whatsappCapable` to drop landlines, VoIP and invalid numbers — the entries that can never receive a WhatsApp message. **Which countries are supported?** Global — libphonenumber covers every country's numbering rules. *** ### ⚖️ Use responsibly This tool validates and formats phone numbers. You are responsible for having a lawful basis and any required consent before contacting people, and for complying with WhatsApp's terms, the TCPA, GDPR and other applicable laws. # Actor input Schema ## `phoneNumbers` (type: `array`): Phone numbers to validate (one per line). Include the country code with a leading + when possible, e.g. +14155552671. Numbers without a + are parsed using the Default country below. ## `numbersText` (type: `string`): Optional. Paste many numbers at once (one per line, or comma/semicolon separated — e.g. a copied spreadsheet column). They are merged with the list above and de-duplicated. ## `defaultCountry` (type: `string`): ISO 3166 alpha-2 region code (US, GB, BR, IN, DE, ...) used to interpret numbers that don't start with +. Leave empty to require + on every number. ## `onlyValid` (type: `boolean`): If on, drop numbers that fail validation from the output (cleaned list only). ## `onlyWhatsappCapable` (type: `boolean`): If on, keep only valid mobile (WhatsApp-capable) numbers — ideal right before a WhatsApp campaign. ## `exportFormat` (type: `string`): default = full JSON. csv = flat CSV-friendly columns. both = JSON + nested \_csv. ## Actor input object example ```json { "phoneNumbers": [ "+14155552671", "+442071838750", "+5511991234567", "+919876543210" ], "defaultCountry": "US", "onlyValid": false, "onlyWhatsappCapable": false, "exportFormat": "default" } ``` # API You can run this Actor programmatically using our API.
