Free Tool: RCS Reach Checker

The RCS reach checker is a free, browser-side utility on the developer tools hub. It estimates whether a destination number can receive RCS — before you commit to an RCS onboarding path or launch in a new market.

​
What the tool estimates

RCS (Rich Communication Services) only works when two things line up:
  1. Country coverage — Orbit publishes an RCS rate for the destination country, which is what can make RCS origination available there at all.
  2. Line type — RCS is a mobile-device channel. A landline, toll-free, or other non-mobile number can never receive it, regardless of country coverage.
The checker composes those two facts into a reach class. It is an estimate, not a delivery guarantee — a live per-number RCS capability probe (whether this handset has RCS/Google Messages enabled right now) requires a billed, authenticated provider query, so no public, unauthenticated tool can perform one. Final delivery still depends on the recipient’s device and carrier RCS enablement.

​
Inputs

One input: a phone number in E.164 format (country code + number, with no other input required). The checker runs entirely in the browser — the number is never sent to a server, so you can paste real customer numbers without worry.

​
Reading the verdict

The tool returns one of four reach classes per number: Alongside the verdict the panel shows the resolved country and line type so you can see exactly which fact the verdict was built on. For channel detail beyond reach, read the RCS channel page and the RCS onboarding guide; the RCS UP3 guardrails page covers the universal-class content policies that apply once you’re sending.

​
How reach relates to country rules

“RCS reachable” is a channel verdict, not a compliance verdict. Countries also gate on sender registration — alphabetic Sender IDs require pre-registration in some markets before your first send can go through. Translate the verdict into a launch decision with the two compliance references:
Registration requirements are granted by each country’s carrier or regulator, not by Orbit — the matrix tells you what to plan for, not a delivery guarantee.

​
Choosing markets

Use reach together with the matrix before you commit to a launch market. A market that scores “Likely reachable” on the checker but carries a sender-registration required flag may add weeks of lead time to your launch; a market that scores “Not covered for RCS” but carries the SMS coverage you need may still be viable on a different channel. Reach verdicts are a planning instrument, not a go/no-go gate — they size the addressable audience so you never commit to a market without knowing whether your destination numbers take RCS at all.
