FAQ
WhatsApp Advanced Checker questions
Can I check phone numbers against WhatsApp in bulk? +
Yes. Upload a CSV of numbers or call the REST API, then download a result file with a registered or not-registered verdict for every number. You are billed only for successful checks.
Does the check message or notify the person? +
No. The check is passive and reads registration signals only. Nothing is sent to the number, and the account holder is never contacted or notified.
Is there a free trial? +
Yes. Contact our support team to claim 1,000 free checks for testing. After that every check is pay-as-you-go with no monthly fee, and the credits you top up never expire.
