Detection signals
What Messenger Checker detects
Messenger runs as its own app under Meta, separate from the Facebook app itself, and many people keep it installed for chats even when they rarely open Facebook directly. Messenger Checker confirms registration status without messaging the number or logging in to any account.
Registration status
Confirms whether the phone number is registered on Messenger (yes or no), so you can filter out unregistered numbers before outreach.
Independent of Facebook activity
A Messenger registration is a separate signal from Facebook registration, since many people keep Messenger as their default chat app while barely opening Facebook itself.
Passive, no contact
Reads registration signals only. The account holder is never messaged, logged in to, or notified.

FAQ
Messenger Checker questions
Can I check phone numbers against Messenger in bulk? +
Yes. Upload a CSV of up to hundreds of thousands of numbers or call the REST API, then download a result file with a registered or not-registered verdict for every number. You are billed only for successful checks.
Does the check message or notify the person? +
No. The check is passive and reads registration signals only. Nothing is sent to the number, and the account holder is never contacted or notified.
What does a "yes" result mean exactly? +
It means the number is linked to a registered Facebook Messenger account. It does not confirm the account is currently online or active at that moment.
Is there a free trial? +
Yes. New accounts receive free checks on signup, and every check is pay-as-you-go with no monthly fee.
