Quick Facebook Phone Number Verification

Facebook remains a top choice for marketers, offering various promotion channels such as posts, groups, and livestreams, enabling precise marketing across a large user base.

One key advantage of Facebook is that you don’t need to be friends with someone to send messages or promotions. As long as you have their phone number, you can engage potential leads directly, making Facebook ideal for outbound marketing.

Using this feature, marketers can reverse-check phone numbers to see if they are linked to active Facebook accounts, helping narrow the audience and improve campaign accuracy. Common verification methods include:

The first is using Facebook’s login page. Enter the target phone number with a random password. If the account exists, Facebook will show an incorrect password message; if it says the account doesn’t exist or the number isn’t linked, you can safely assume the number is unregistered.

The second method uses Facebook’s contact sync feature in the mobile app. When enabled, Facebook scans your contacts and highlights which numbers are registered. This is convenient but requires storing numbers on your device and granting Facebook access.

For a more efficient, scalable solution, many marketers rely on CrownSoft’s Various Account Filters. This tool allows bulk importing of numbers and checks their Facebook registration status via account login, outputting the results in list form.

CrownSoft uses official API-level verification, achieving up to 99% accuracy. After filtering, users can export the verified list for direct use in marketing tools or team sharing.
