✅ WhatsApp Number Validator — Live Registration Check, Bulk | $0.80/1K

Live-check whether phone numbers are registered on WhatsApp — in bulk, in parallel, no keys needed. Paste numbers and get back, for each one: whatsappRegistered (true/false), profile picture URL, plus full metadata — 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.

✅ Built-in live WhatsApp check, always on — no login, no QR scan, no API keys, no bans. Every valid, mobile-capable number is checked in parallel for fast bulk processing, so you get a definitive true / false for the whole list.

📣 Update — from 31 July 2026: big reliability upgrade to the live WhatsApp check — a much higher match rate and far fewer missed numbers, so valid WhatsApp users are no longer marked as "not registered". Faster at scale, and now at a lower price (see below). Same simple input, better output.

🤖 For AI agents — MCP & Standby (validate on demand)

Run this Actor in Standby mode for a warm HTTP + MCP endpoint that validates a single number per call — the perfect step inside an agent or automation flow (clean a lead before you message it). Fully offline, so it answers instantly.

• MCP tool: validate_number → validity, E.164/international/national formats, country, region, carrier, line type and a whatsappCapability grade (yes/maybe/no).
• REST (same endpoint): GET /?number=+14155552671 (optional &defaultCountry=US)

Turn on Standby in the Actor's settings to get your endpoint URL.

🔗 Use it in n8n

There's a dedicated n8n community node — n8n-nodes-apivault-whatsapp-validator. Perfect for a "new lead → validate → only message real WhatsApp users" automation.

1. In n8n: Settings → Community Nodes → Install → n8n-nodes-apivault-whatsapp-validator.
2. Add an Apify API credential (your token from Apify Console → Settings → Integrations).
3. Drop the WhatsApp Number Validator node in, pass phoneNumbers (or numbersText), and pipe the clean records (whatsapp true/false, e164, carrier, country, whatsappProfilePic …) into your CRM, Google Sheets, or a WhatsApp / SMS sender node.

Prefer no install? The generic Apify node can run this Actor too. And in Standby / MCP mode you can validate a single number per call for real-time, per-lead checks inside a live workflow.

⚡ Quick start

{
  "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.

❓ FAQ

Does whatsapp: true mean it's really on WhatsApp? Yes — when the live check returns true, the number is registered on WhatsApp right now. When it returns false, it's not. The live check is always on — every valid, mobile-capable number is checked, so you get a definitive true/false for the whole list.

Why do some numbers show whatsappCapable: true but whatsapp: false? whatsappCapable means the line can hold a WhatsApp account (it's a mobile / mobile-capable number). whatsapp is the live result — whether an account is actually registered on that number. A capable number with no WhatsApp account returns whatsappCapable: true, whatsapp: false.

Which countries are supported? Global — libphonenumber covers every country's numbering rules.
