## Key takeaways
- RCS OTP and verification messages arrive in Google Messages with a verified brand sender and read receipts.
- Com.Bot builds, sends and tracks them from one platform, with RCS reach on supported devices and carriers.
- Authentication templates carry one-time passcodes only; promotional content belongs in marketing messages.

## Highlights
- **Verified brand sender:** Messages arrive from your verified business name with a logo and badge, not a random short code. Customers see who is asking before they share a code.
- **Read receipts on delivery:** RCS shows when a message is delivered and read, so support teams know whether a customer actually saw the code before resending.
- **RCS reach on supported devices:** RCS reaches customers on supported Android phones and carriers, so check reach before a campaign. For customers who cannot get RCS, a business in India can choose to send a separate SMS campaign from Com.Bot.
- **One platform, many channels:** Run RCS alongside WhatsApp, Instagram, Messenger and your website chat widget from the same Com.Bot inbox and automation builder.

## Use cases
### 1. Login OTP Delivery
A fintech app sends a one-time passcode for a new device login. The customer verifies in seconds without leaving the messaging app.
- PayNest Finance: Your PayNest verification code is 482913. It expires in 5 minutes. Never share this code with anyone.

### 2. Signup Phone Verification
A D2C skincare brand confirms a new account phone number at signup. Verified numbers reduce fake accounts and failed deliveries.
- Luma Skincare: Welcome to Luma Skincare. Use code 731204 to verify your phone number and finish creating your account.

### 3. Order COD Confirmation
A furniture store verifies a cash on delivery order before dispatch. Confirmed orders cut failed deliveries and return costs.
- UrbanNest Furniture: Your UrbanNest order #4821 is placed for Cash on Delivery. Reply YES to confirm and we will dispatch today.
- Customer: YES

### 4. Password Reset Code
A coaching institute sends a reset code when a student forgets their portal password. Support tickets for login issues drop.
- Brightpath Academy: Use code 905337 to reset your Brightpath Academy password. The code expires in 10 minutes.

### 5. Payment Authentication
A utility services app authenticates a card payment with a one-time code. The customer approves the charge in the same thread.
- ClearBill Utilities: Code 118742 authorizes your ClearBill payment of the amount shown in the app. Do not share this code.

### 6. Delivery Address Verification
A grocery delivery service confirms a new delivery address before the first order ships. Wrong-address redeliveries fall.
- FreshCart Grocery: Please confirm your new delivery address for order #7719. Reply CONFIRM if it is correct.
- Customer: CONFIRM

## What are RCS OTP and verification messages
RCS OTP and verification messages are one-time passcodes and account verification messages sent over Google RCS Business Messaging (RBM) instead of plain SMS. RCS is the rich messaging standard built into Google Messages on supported Android phones, and it also works on other devices where the carrier and device support it. A verification message typically carries a short numeric or alphanumeric code that the customer enters to confirm a phone number, complete a login, reset a password or approve a transaction.

Because RCS supports a branded sender with your logo and a verified badge, images, suggested reply buttons and read receipts, a verification message looks like it comes from a real business rather than an unknown number. That matters when customers are asked to trust a code. The message still needs to be short, clear and sent only to someone who requested it, but the presentation is far better than a plain text SMS.

On Com.Bot, RCS verification runs through the same automation builder you use for WhatsApp, Instagram and Messenger. You define the trigger, the template and the steps, and Com.Bot handles delivery, retries and reporting. You do not need a separate vendor for RCS and another for WhatsApp.

- One-time passcodes for login, signup and password reset
- Phone number and account verification for new users
- Transaction approval codes for payments and high-value actions
- Delivery and read status visible in the Com.Bot inbox
- Check RCS reach on the device and carrier before you send
- Branded sender with logo and verified badge after agent verification

## Why send RCS OTP and verification messages on Google RCS
SMS verification works, but it is plain and easy to ignore. RCS verification messages appear in the same messaging app with your brand name, logo and verified badge, so the customer can see the code is from you. Read receipts tell your support team whether the message was opened, which reduces the back-and-forth when a customer says they never received it. Suggested reply buttons can let the customer tap to resend or get help without typing.

RCS also supports richer content than SMS. You can include a short line of context, a button to copy the code, and a link to your help page if the customer did not request the code. That extra context lowers support tickets and makes the verification step feel like part of your product rather than a separate system. For businesses in India, the Middle East, Europe and other markets where RCS adoption is growing, this is a practical upgrade over plain SMS.

Com.Bot treats RCS as one channel in a multi-channel platform. If a customer later messages you on WhatsApp or Instagram, the same contact record and automation can pick up the conversation. You are not building a separate stack for every channel, and you are not juggling separate tools for the WhatsApp side of your communication.

- Branded sender with logo and verified badge after verification
- Read receipts show whether the code was seen
- Suggested reply buttons for resend and help
- Checking RCS reach keeps verification working for more customers
- Same platform as WhatsApp, Instagram, Messenger and web chat
- WhatsApp message charges billed separately from the plan

## How to set up RCS OTP and verification messages in Com.Bot
Start by connecting your RCS agent. RCS Business Messaging requires agent verification before launch, and Com.Bot helps you prepare the brand details, use case and sample messages that carriers and Google review. Once the agent is verified, you can send from your branded sender. If you also use WhatsApp, connect your WhatsApp Business API channel in the same Com.Bot account so both channels share contacts and automation.

Next, build the verification flow in the visual drag-and-drop bot builder. A typical flow has a trigger (for example, a signup form submission or a login attempt), a step that generates or receives the one-time code from your system, a send step that delivers the RCS template, and a wait step that checks whether the code was entered. If the code is not entered within a set time, the flow can resend. You can also route the customer to a human agent in the shared team inbox if they reply with a question.

Finally, set up reporting. Com.Bot shows delivery and read status for RCS messages, and you can track how many verification attempts succeed on the first send and how many need a resend. That data helps you tune the template wording and the timing. Because Com.Bot is an official Meta Business Partner with direct WhatsApp Business API integration, the same account can run WhatsApp verification templates alongside RCS, which is useful when your customer base spans both channels.

- Connect and verify your RCS agent with Com.Bot support
- Build the OTP flow in the drag-and-drop bot builder
- Add a wait step and a resend
- Route replies to the shared team inbox with role-based access
- Track delivery, read status and resend rates
- Run RCS and WhatsApp verification from one account

## RCS OTP and verification messages rules and compliance
RCS Business Messaging has its own rules, and verification messages are treated as authentication traffic. The message must be sent only to a user who requested it, and the content should be limited to the code and the minimum context needed. Do not add promotional lines, offers or upsells to an authentication message. If you want to send an offer, send it as a separate marketing message with the correct consent and category, and keep it out of the verification flow.

On WhatsApp, the equivalent rules are stricter and well documented: business-initiated messages must use Meta-approved templates and go only to contacts who opted in. Template categories are marketing, utility and authentication. Authentication templates are for one-time passcodes only. A cart reminder or an offer is marketing, never utility. A shipping update for an order the customer already placed is utility. These category rules matter because misclassification can hurt your quality rating and messaging limits. The same discipline applies to RCS: keep authentication messages clean and separate from promotion.

The green tick or verified badge is granted by the platform, not by a provider. For RCS, agent verification is handled through Google and the carriers. For WhatsApp, Meta grants the official business account status, and providers like Com.Bot can help you apply but cannot guarantee it. Com.Bot is an official Meta Business Partner with direct WhatsApp Business API integration, so the WhatsApp side of your verification stack is on solid ground. For RCS, Com.Bot helps you prepare and submit the agent verification details.

- Send authentication messages only to users who requested them
- Keep offers and promotions out of verification templates
- Use the correct template category on WhatsApp: authentication, utility or marketing
- Never call a cart reminder or offer a utility template
- Verified badges are granted by the platform, not by a provider
- Agent verification is required before RCS launch

## Mistakes to avoid with RCS OTP and verification messages
**Short answer:** The most common mistake is mixing promotion into verification, such as adding a discount line to a code message. Another is sending verification messages to people who did not request them, which can get you blocked. Also check which customers RCS can reach, since RCS is not available on every device and carrier, and track read status so you are not guessing about delivery.

The most common mistake is mixing promotion into verification. A code message that ends with a discount line may get flagged, and it also confuses the customer about what the message is for. Keep the code, the context and the action separate. Another mistake is sending verification messages to people who did not request them. That is a quick way to get blocked and to damage your sender reputation. If you are re-engaging a customer, use a marketing message with proper consent, not an authentication template.

A second mistake is not checking which customers RCS can reach. RCS is not available on every device and carrier, so a verification flow that only sends RCS will fail for some customers. Plan how to reach the rest, for example a WhatsApp campaign or, in India, a separate SMS campaign from Com.Bot. Test that path before you go live. A third mistake is not tracking read status. If customers say they did not receive the code, read receipts tell you whether the message was delivered and opened. Without that data, you are guessing.

A fourth mistake is treating RCS as a standalone system. If your customer also uses WhatsApp, you want one contact record and one automation layer. Com.Bot gives you that. A fifth mistake is underestimating verification lead time. RCS agent verification takes time, so start early and have your brand assets and sample messages ready. Com.Bot support can help you prepare the submission.

- Do not add offers to authentication messages
- Do not send verification messages without a request
- Always check RCS reach before you send
- Track read receipts to answer delivery questions
- Keep RCS and WhatsApp in one platform where possible
- Start agent verification early

## Measuring results and costs for RCS OTP and verification messages
**Short answer:** Measure delivery rate, read rate and first-attempt success for RCS OTP and verification messages. If first-attempt success is low, the issue is usually template wording, code expiry time or RCS reach. RCS pricing depends on the carrier and market and is separate from WhatsApp message charges, which are billed separately from the plan based on category and the recipient's country. Plans are billed quarterly.

Measure three things: delivery rate, read rate and first-attempt success. Delivery rate tells you how many messages reached the device. Read rate tells you how many were opened. First-attempt success tells you how many customers entered the code without needing a resend. If first-attempt success is low, the issue is usually template wording, code expiry time or RCS reach. Com.Bot reports these metrics so you can improve the flow without guesswork.

On cost, RCS pricing depends on the carrier and the market, and it is separate from WhatsApp message charges. For WhatsApp, message charges are billed separately from the plan, based on message category and the recipient's country, and customers can ask the team for current rates. There is no monthly conversation cap or fair usage limit. Plans are billed quarterly in USD: Silver at $149, Gold at $349 (recommended) and Platinum V1 at $2,500. Each plan includes a set number of contacts, team members, bot triggers and external actions. Add-ons include extra team members, social channels or ecommerce stores at $10 per month each, external actions at $10 per 5,000 and bot triggers at $10 per 25,000. Expert help is available at $49 per hour for WABA, CRM and inbox, and $99 per hour for ecommerce, bots and automations.

For a small business sending a few thousand verification messages a month, the Silver plan is usually enough. For a growing D2C brand or an agency managing multiple clients, Gold adds more team members, more bot blocks and faster support. Platinum V1 is for high-volume operations that need multiple WhatsApp API channels, more contacts and higher throughput. You can pay by card, UPI, PayPal, crypto or bank transfer, and you can start at https://v3.com.bot/register or talk to sales on WhatsApp at +91 080 6987 1810.
