Detection signals
What RCS Checker detects
RCS isn't an app or an account someone signs up for — it's a messaging protocol that carriers and device makers switch on automatically for compatible Android hardware, so a check here reads a network and device capability rather than a signup event. RCS Checker confirms whether a phone number has RCS enabled, without messaging or storing the number.
RCS enablement status
Confirms whether the phone number has RCS enabled (yes or no), so you can decide whether to send RCS or fall back to SMS.
No sign-up involved
Because RCS turns on at the carrier and device level rather than through user registration, an enabled result reflects network and device capability, deciding whether to send richer RCS messages or fall back to plain SMS.
Device operating system
Returns the available device OS signal as iOS or Android, alongside the RCS registration result.
Passive, no contact
Reads RCS capability signals only. The number holder is never messaged, logged in to, or notified.

FAQ
RCS Checker questions
Can I check phone numbers against RCS in bulk? +
Yes. Upload a CSV of up to hundreds of thousands of numbers or call the REST API, then download a result file with an RCS enabled or not-enabled verdict for every number. You are billed only for successful checks.
Does the check message or notify the person? +
No. The check is passive and reads RCS capability signals only. Nothing is sent to the number, and the number holder is never contacted or notified.
What does a "yes" result mean exactly? +
It means the number has RCS (Rich Communication Services) enabled by its carrier or device, so messages can be sent as RCS instead of falling back to SMS. It does not confirm current network availability.
Is there a free trial? +
Yes. New accounts receive free checks on signup, and every check is pay-as-you-go with no monthly fee.
