FAQ WhatsApp
Can I check phone numbers on WhatsApp in bulk?
Yes. Upload a CSV of up to hundreds of thousands of numbers or call the REST API, choose the task type you need, then download a result file with a registration verdict for every number. You are billed only for successful checks.
Does checking a number send a WhatsApp message or notify the person?
No. The check is passive and reads registration and public profile signals only. Nothing is sent to the number, and the account owner is never messaged or notified.
Can I tell WhatsApp Business accounts from personal ones?
Yes. The activity task type returns a WhatsApp Business flag alongside available activity time and active days, so you can segment businesses from individual users.
Is there a free trial for the WhatsApp checker?
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.
