Quick answer. Consumer RCS, through Google Messages, is available in most countries worldwide. Business RCS (verified, branded A2P messaging) is available in a smaller but fast-growing set — strong markets include the US, Canada, UK, France, Germany, Italy, Spain, Netherlands, Brazil, Mexico, India, and others — with exact coverage depending on the carriers and the provider you use. Apple's iPhone RCS support is also rolling out country by country. India and the wider Asia-Pacific region lead in RCS business-messaging adoption.
The distinction matters: a consumer in most countries can use RCS in Google Messages today, but a business's ability to send branded RCS to a given country depends on operator support there and on its messaging provider's reach. Coverage maps change frequently as carriers and Apple expand support.
As a concrete reference, one major cloud messaging provider expanded RCS for Business to 22 countries in 2026 (US, Canada, and 20 others across Europe and Latin America plus Singapore) — a snapshot of how business coverage is widening. SimplyRCS focuses specifically on the US market.
