Facebook Phone Number Checker

Facebook Account Checker takes a list of phone numbers and tells you, for each one, whether a Facebook account exists for that number — no login, no friend requests, no ban risk.

What does Facebook Account Checker do?

Give it phone numbers in international format and it returns, per number, whether a Facebook account is registered to it. Run it on the Apify platform for API access, scheduling, integrations, automatic proxy rotation, and run monitoring.

Why use Facebook Account Checker?

• Lead qualification — see which contacts are reachable on Facebook.
• List hygiene — flag numbers with no social presence before a campaign.
• Audience research — measure Facebook coverage across a phone list.
• Bulk, structured output — one row per number, ready to export.

How to use Facebook Account Checker

1. Open the Input tab.
2. Paste your phone numbers into Phone Numbers (international format, e.g. +15551234567).
3. Keep Proxy on Apify Residential for best reliability.
4. Click Start and read the results in the Output tab.

Data table

Field	Meaning
phone_number	The number checked, normalized to international format.
on_facebook	true if a Facebook account exists for this number, false if not.
success	true when the check completed; false if it could not be resolved.
error	Reason a row could not be checked (invalid format, temporary block, etc.).

How much does it cost?

Checks are lightweight — most runs cost a fraction of a cent per number in platform compute. Batch numbers into a single run to minimize overhead.

Tips

• Feed numbers in bulk rather than one run per number.
• Keep the residential proxy enabled for large lists to avoid temporary blocks.
• Schedule recurring runs to keep a contact list continuously validated.

FAQ & support

• Is this legal? The Actor only reads publicly observable account-existence signals and never logs in. You are responsible for complying with applicable laws and Facebook's terms when processing personal data.
• Why is a row errored? The number was malformed or the check was temporarily blocked — check the error column and retry.
• Found a bug or need a custom version? Open an issue on the Actor's Issues tab.
