Multi-Platform Number Filtering Tips

A critical factor in successful international marketing is scaling across multiple digital channels. Marketers often choose regionally dominant social media platforms to boost reach and engagement.

For example, Facebook has its largest user base in India, followed by the U.S. and Southeast Asian countries, making these regions key for Facebook marketing. Twitter (X), meanwhile, is most popular in the U.S. and Japan, making it ideal for campaigns in those markets.

These platforms generally require users to register with mobile phone numbers. As a result, marketers collect batches of phone numbers in advance to add contacts and carry out private messaging campaigns. Recently, new tools have emerged to make these processes more efficient.

So, is filtering phone numbers across platforms necessary in foreign trade marketing? And if yes, how should it be done?

Before launching campaigns, especially direct messaging, verifying phone numbers is crucial. Sending bulk messages to numbers not linked to active accounts risks platform flags, suspensions, or bans, significantly hurting your marketing results.

This is true not only for Facebook and WhatsApp but also many other platforms. Targeting unknown or unverified numbers is risky and ineffective.

Practically, there are two common approaches to filtering numbers: manual checking and automated tools.

Manual checking involves entering each phone number into an “Add Friend” or search feature to see if a valid profile exists. While reliable, this method is slow.

Automated filtering tools like CrownSoft’s Multi-Account Filter can quickly detect if numbers are registered on WhatsApp, Facebook, Telegram, Instagram, and more. The software is user-friendly, suitable even for beginners.

Once data is collected, it can be sorted by platform, enabling marketers to target their audience more precisely and improve campaign efficiency.
