RC RCS
RCS is one of the core channels in the CheckNumbers catalog — the same services available inside @checkerNUM_bot on Telegram. Marketers use it to see whether a phone number is registered before spending on SMS, push, or chat ads.
Unlike web dashboards that process uploads in-browser, CheckNumbers keeps execution in Telegram: you send a file, pick the RCS check type, and receive an Excel report. Browse the catalog here — processing runs only in Telegram.
Teams in CIS, EU, LATAM, and APAC combine RCS checks with WhatsApp or Telegram pipelines to build high-intent segments for affiliate, iGaming, e-commerce, and B2B outreach.
