SMS is notoriously easy to spoof: scammers routinely fake sender IDs and short codes, which is why text phishing (“smishing”) is rampant. RCS raises the bar by tying every business message to a vetted, branded identity, so the verification badge becomes a trust signal consumers can look for.
No system is perfectly immune, attackers may still try to abuse unverified channels or fall back to SMS, which is exactly why the verified-sender badge matters: it gives consumers a reliable way to tell a real brand message from an imposter.
Key facts
- Verified RCS agents are vetted by carriers/Google; the brand identity isn’t trivially forgeable like an SMS sender ID.
- CTIA guidance explicitly says message-number spoofing should be avoided and must comply with applicable law.
- The verification checkmark is the consumer’s anti-spoofing signal.
