Before reaching out to a new business contact, check which messaging apps they use. If a number is registered on WhatsApp and Telegram, you know you have multiple channels to connect. No more guessing which platform a client or partner prefers.
For WhatsApp marketing and Telegram marketing campaigns, you need to know which numbers are actually on those platforms. Our checker identifies WhatsApp-registered numbers, Telegram users, and more — so you don't waste campaign budget on numbers that can't receive your messages. Learn about list cleaning →
Got a phone number from a lead? Enrich it with social media presence data. Knowing a lead is on Instagram, Facebook, and Telegram tells you where to focus your outreach. Multi-platform presence signals active, engaged users who are more likely to respond.
Yes. Our detection engine queries Facebook's registration API to check if a phone number is associated with a Facebook account. Combined with Instagram (owned by Meta), you can verify presence across the Meta ecosystem. Note: Facebook's privacy settings may limit detection for accounts with phone number visibility disabled.
Our tool detects whether a phone number is registered on Instagram, but it does not reveal the Instagram username or profile. It's a presence check, not an identity reveal. This respects user privacy while giving you the signal you need: is this number on Instagram or not?
We support 40+ apps including messengers (WhatsApp, Telegram, Signal, Viber, Line, WeChat, KakaoTalk, Zalo), social networks (Facebook, Instagram, TikTok, Snapchat, Twitter/X, LinkedIn), and service platforms (Binance, Amazon, Google, Apple, PayPal). Each app check runs independently for maximum accuracy.
