RCS OTP is a one-time password delivered through RCS Business Messaging instead of plain SMS- the code arrives inside a message carrying your Google-verified business name, logo, and badge, making it harder for a fraudster to impersonate and easier for a customer to trust at a glance.
A one-time code sent from an unmarked number is exactly what phishing texts imitate- customers have learned to be suspicious of any SMS asking them to act on a code, which slows down legitimate authentication too. Any business running login, transaction, or account-change verification needs a way to prove the code genuinely came from them, not just deliver it.
RCS OTP solves that with sender identity baked into the channel itself- the verification badge, logo, and business name are the same trust signal covered on our RCS brand verification page, applied specifically to the authentication moment where trust matters most.
RCS doesn't just deliver the code faster- it changes what the code arrives attached to. Google's brand verification process confirms your business identity before any message goes out, so the OTP inherits that verified status automatically. That's a structural difference from SMS, where any sender ID can be spoofed with no verification step at all.
A login attempt, transaction, or password reset request calls Get Click Media's API to generate a one-time code.
The code goes out as an RCS message carrying your verified business name, logo, and badge- not an unmarked number.
The code lands inside Google Messages, visibly tied to your brand, which makes it easier to trust and harder for a fraudster to imitate.
On a device without RCS support, the same code delivers as plain SMS automatically- authentication is never blocked by channel availability.
A one-time code tied to a verified sender for account sign-in, reducing the chance a customer mistakes a phishing text for your real login prompt.
RCS OTP slots in as the second factor for any 2FA flow- login, password reset, or sensitive setting change- alongside your existing authentication logic.
Transaction confirmation codes for fund transfers, card activation, and high-value approvals, delivered with the verified badge banking customers now look for.
Confirm a new customer's number during signup with a code sent through a channel that's visibly the business, not an anonymous shortcode.
Verified sender identity closes the spoofed-sender-ID gap that phishing texts exploit, making it harder for attackers to impersonate your OTP messages.
A verified logo and badge next to the code reassures customers it's genuinely from you, not a lookalike phishing attempt.
Spoofing a verified RCS sender is far harder than spoofing a plain SMS sender ID, closing a common fraud vector.
A clearly branded message reduces the confusion and hesitation that causes customers to ignore or delete unmarked OTP texts.
Automatic SMS fallback means every customer receives their code, whether or not their device supports RCS.
| Aspect | Plain SMS | RCS |
|---|---|---|
| Sender identity | A phone number or shortcode- easy to spoof. | Verified business name, logo, and badge tied to Google's brand verification. |
| Phishing risk | High- lookalike sender IDs are a known fraud pattern. | Lower- verification makes impersonation significantly harder. |
| Format | Plain text code only. | Branded rich card with your logo alongside the code. |
| Delivery guarantee | Universal, but unverified. | Native RCS with automatic SMS fallback- same universal reach, plus verification when available. |
RCS OTP integrates through Get Click Media's RCS API- your existing authentication service calls the API to trigger a code the same way it would call an SMS gateway, with brand verification and SMS fallback configured once during onboarding rather than per request.
RCS OTP is priced per message like any other transactional RCS send, with the occasional SMS fallback billed at standard SMS rates. See our RCS Pricing India page for current rates, or talk to us for volume-based authentication pricing.
Google's verification review is managed as part of onboarding, so your OTP messages carry a verified identity from day one.
No separate integration needed for unsupported devices- fallback is configured once and applies to every send.
Authentication codes are time-critical- our infrastructure is built around fast, reliable transactional delivery.
The same RCS API integration that powers OTP also supports order updates, reminders, and support flows, if you need them later.
Get Click Media enables brands to secure customer authentication with verified RCS OTP delivery.
