Detection signals
What Facebook Account Checker detects
Facebook Checker confirms whether a phone number is registered on Facebook, without messaging or storing the number. Every row comes back with a clear registered or not-registered verdict, ready to clean lists, match audiences, or route into your CRM.
Registration status
Confirms whether the phone number is registered on Facebook (yes or no), so you can filter out unregistered numbers before outreach.
Banned account flag
Facebook checks can also return a banned status, so you can separate disabled accounts from active registered ones.
Bulk yes/no verdict
Every number comes back with a clear registered or not-registered result, ready to filter and segment.
Passive, no contact
Reads registration signals only. The account holder is never messaged, logged in to, or notified.

Facebook is checked by phone number here. If you need to check by email address instead, use Facebook Email Checker.
