Every check runs through official platform APIs on our own infrastructure. You never connect, bind, or use your own account, phone number, or SIM card — just upload your list or call the API and get results.
CheckNumber's Facebook checker tells you whether a phone number or email address belongs to a registered Facebook account, and flags banned accounts, without logging in, messaging, or contacting the user. Upload a CSV of numbers or emails, or call the REST API, and every record comes back with a clear verdict, ready to clean lists, match audiences, or route into your CRM.
What CheckNumber detects for Facebook
Facebook account by phone
Confirms whether a phone number has a registered Facebook account (yes or no).
Banned account flag
Returns a ban result when the number maps to a banned or disabled Facebook account, so unusable contacts are filtered early.
Facebook account by email
Confirms whether an email address is registered with Facebook (yes or no).
Bulk verdict
Every number or email comes back with a clear 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 FAQ
Can I check numbers or emails against Facebook in bulk?
Yes. Upload a CSV of phone numbers or email addresses, or call the REST API, choose the matching task type, then download a result file with a verdict for each record. You are billed only for successful checks.
What does the ban result mean?
For phone checks, Facebook can return yes, no, or ban. A ban result means the number maps to a banned or disabled Facebook account, which you will usually want to exclude from outreach.
Do you check by phone number, email, or both?
Both. The number task type checks phone numbers and the email task type checks email addresses against Facebook registration, so you can use whichever identifier your list contains.
Is there a free trial?
Yes. New accounts receive 1,000 free checks on signup with no credit card, and every check is pay-as-you-go with no monthly fee, and the credits you top up never expire.
