How to Get Valid Facebook Numbers for Marketing

Facebook has become one of the most widely used social platforms in the world, with support across more than 190 countries and over 2 billion daily active users. Its massive user base and global visibility make it a natural choice for marketers looking to promote products or services.

Unlike some platforms, Facebook allows users to register and log in using their phone numbers, which presents a unique opportunity for marketers. By collecting phone numbers in advance, businesses can reach potential clients directly, using methods like posts, comments, group interactions, and private messaging — all without the need for a friend request.

Because of this, preparing a reliable phone number list has become a standard part of many marketing workflows. However, marketers often face one common issue: not every phone number they collect or purchase is actually registered on Facebook. Reaching out to unregistered numbers wastes both time and resources, which lowers the overall effectiveness of a campaign.

To fix this problem, marketers now use number validation tools before launching outreach efforts. One such tool is the Various Account Filters software by CrownSoft.

Using this tool is simple. You upload your list of phone numbers and log in with the required account credentials. The software will then automatically detect which of the numbers are currently linked to Facebook accounts. This ensures that you’re only marketing to real, reachable users.

Even if you don’t have a phone number list yet, CrownSoft has you covered. It includes built-in number generation features that support formats like:Country code + custom numeric segments、Country + city + number range.

Once you’ve generated your number list, you can immediately verify which entries are usable for Facebook. This makes it easy to quickly build a targeted database of potential leads.

By combining phone number generation and account verification in one system, the tool gives marketers a fast and efficient way to prepare for Facebook outreach — all with just a few simple steps.
