CheckNumber 能为 WhatsApp 检测什么
Registration status
Confirms whether the phone number has a registered WhatsApp account (yes or no), so you can filter out unregistered numbers before outreach.
Activity duration
Returns how many days the WhatsApp account has been active, helping you gauge how established and live the user is.
WhatsApp Business account
Flags whether the number is a WhatsApp Business account, so you can separate businesses from personal users.
Business status
Returns the available Business flag with activity time and active-day signals.
Profile photo
Returns the public WhatsApp profile photo URL when available. Automated analysis may provide the probabilistic visual estimates described below.
Photo attributes
From an available public profile photo, provides probabilistic age-range and gender estimates plus a picture-type classification such as portrait, pet, or object.

Core WhatsApp data
Core data available by task type
These are the main data categories users can receive from each WhatsApp product. Exact response keys and casing remain in the API documentation.

- Whether the number returns an active WhatsApp account result.
Activity check
ws_active - Account activity

WhatsApp 常见问题
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. New accounts receive 1,000 free checks on signup with no credit card, and every WhatsApp check is pay-as-you-go with no monthly fee, and the credits you top up never expire.
