RCS Business Messaging: A Practical Guide for 2026

RCS Business Messaging (RBM), now branded by Google as RCS for Business, upgrades the text message. Customers see your logo, name and a verified badge, plus images, carousels and buttons — inside the phone's built-in messaging app, with no app to download.

In Short

You create an RCS agent, verify your brand and get launch approval from Google, carriers or both. Once approved, you can message RCS-capable customers on those networks and fall back to SMS for everyone else.

How RCS Agents Work

  • An agent represents your brand in messaging apps such as Google Messages and iMessage, showing your name, logo, description and contact details (Google for Developers).
  • Each agent has a use case — OTP, Transactional, Promotional or Multi-use — with content rules for each (Google for Developers).
  • Launch includes brand verification and launch approval. Some carriers are Google-managed; others manage approval themselves and may need a direct agreement (Google for Developers).
  • Launch requests describe triggers, the conversation flow and opt-out keywords such as STOP with the confirmation message (Google release notes).

What You Can Send

  • Rich cards and carousels with images, titles and descriptions.
  • Suggested replies and actions, such as open a link, dial, view a location or add to calendar.
  • Branded, verified sender details that make phishing harder to pass off as you.

Plan for Fallback

Not every customer, phone or network supports RCS. Check capability before sending and fall back to SMS when RCS isn't available. In Arino One, routing rules handle the fallback, so a customer always gets the message on something.

When RCS Beats WhatsApp — and When It Doesn't

RCS lives in the default messaging app, so it suits markets where WhatsApp use is lower, such as the US, and messages that replace SMS: delivery updates, appointment reminders and codes. Where WhatsApp is already everyone's chat app, WhatsApp usually gets more replies. See RCS vs SMS and WhatsApp vs RCS vs SMS.

FAQ

Does RCS work on iPhone?

Apple added RCS support to iMessage, and Google lists iMessage among the apps where RCS for Business conversations appear. Business reach still depends on carrier support and launch approval in each market.

How long does RCS agent approval take?

It varies by carrier. Google-managed launches follow Google's process; carrier-managed launches have their own timelines and requirements.

What happens if a customer doesn't have RCS?

Check capability before sending and fall back to SMS. Arino One routing can do this automatically.

Do I need consent for RCS marketing?

Yes. RCS promotional messages follow the same electronic marketing rules as SMS, and launch requests must show opt-out handling. This is general information, not legal advice.
