WhatsApp Number Validator & Checker

What Does WhatsApp Number Validator Do?

WhatsApp Number Validator checks phone numbers in bulk and returns a clear hasWhatsapp result for each unique phone number.

For each phone number, the Actor:

1. Parses and normalizes the phone number where possible.
2. Removes duplicate numbers.
3. Checks whether the number is registered on WhatsApp.
4. Returns hasWhatsapp: true, false, or null.
5. Adds phone metadata such as country, region code, location, and possible time zones.
6. Saves results to the Apify dataset.

What checks are performed?

Check	Description
Phone number parsing	Detects whether the input can be parsed as a phone number
Phone normalization	Converts phone numbers to international E.164 format where possible
Duplicate handling	Checks each unique normalized phone number only once
WhatsApp availability	Checks whether the phone number is registered on WhatsApp
Country detection	Returns country and region code when available
Location metadata	Returns phone-number-based location metadata when available
Timezone metadata	Returns possible time zones inferred from phone number metadata

location and timezones are inferred from phone number metadata. They are not live GPS location data.

hasWhatsapp Values

Value	Meaning
true	The phone number was checked and is registered on WhatsApp
false	The phone number was checked and is not registered on WhatsApp
null	The input was skipped and was not checked

For skipped records, hasWhatsapp is null, not false.

Why Validate WhatsApp Numbers?

• Clean WhatsApp contact lists before campaigns
• Remove numbers that are not registered on WhatsApp
• Reduce wasted outreach volume
• Improve CRM phone data quality
• Validate leads from scrapers, forms, CRMs, Google Sheets, and datasets
• Prepare WhatsApp contact lists before sales, support, or marketing workflows
• Segment contacts by hasWhatsapp before sending messages

Use this Actor only for compliant workflows. Message people only when you have the right to contact them and follow applicable laws and platform rules.

{
  "phoneNumbers": [
    "+919876543210",

• +919876543210 shows a number registered on WhatsApp.
• +14155552671 shows a checked number that is not registered on WhatsApp.

How Do I Use WhatsApp Number Validator?

1. Enter phone numbers in the Actor input.
2. Use international format when possible, for example +1234567890.
3. Include the country code.
4. Run the Actor.
5. Open the dataset to review results.
6. Filter by hasWhatsapp = true to get numbers registered on WhatsApp.

Deduplication and Billing Behavior

• Duplicate phone numbers are normalized and checked only once.
• The Actor returns one result per unique normalized phone number.
• Repeated invalid-format inputs are deduplicated.
• Technical check errors are reported in logs and SUMMARY, but are not returned as dataset results.
• This helps avoid charging users for failed checks.

How much does WhatsApp Number Validator cost?

This Actor uses the Pay-per-result pricing model, so your costs can be easily calculated: it will cost you $2.50 to check 1,000 phone numbers, which is $0.0025 per phone number. Apify provides you with $5 in free usage credits every month on the Apify Free plan, allowing you to check up to 50 phone numbers for free using those credits.
