What is RCS

RCS is the modern carrier-backed messaging standard that extends SMS with richer interactions, higher-quality media, typing indicators, and delivery context where supported.

SMS replacement signal

Know whether a phone is likely reachable through a richer messaging route before you plan a send.

Rich customer experience

RCS can support images, videos, suggested replies, read receipts, and more app-like conversation flows.

Fallback-first planning

Use RCS detection as a routing signal and keep SMS fallback available for unsupported devices, carriers, or regions.

Marketing routes

Why RCS Matters for Marketing

RCS gives campaign teams more context than SMS, especially when read receipts, rich media, and branded interactions are part of the plan.

Read receipts

Plan campaigns with better delivery and engagement visibility where recipient devices and carriers support RCS.

Rich media

Route eligible numbers into flows that can support richer images, videos, cards, and call-to-action buttons.

Smarter fallback

Separate RCS-ready contacts from fallback recipients before campaign execution.

Detection flow

How Detection Works

The workflow evaluates each number against route intelligence, then returns a clean RCS-readiness result for segmentation.

1

Upload CSV or TXT

Use CRM exports, campaign lists, or lead vendor files without changing your workflow.

2

Detect RCS capability

Classify each number as RCS-ready, SMS fallback, unknown, or review.

3

Export route segments

Download files for RCS-ready campaigns, fallback sends, and manual review.

Campaign planning

Use Cases

RCS detection is most useful when messaging teams want richer campaigns without giving up SMS coverage.

Future-proof SMS strategy

Measure how much of your list can move from plain SMS into richer routes as carrier and device support improves.

Hybrid SMS+RCS campaigns

Split one list into RCS-ready and SMS fallback segments before loading it into your sending stack.

FAQ

RCS Number Checker FAQ

What's RCS vs SMS? +

SMS is the older basic text standard. RCS adds richer messaging capabilities such as higher-quality media, typing indicators, delivery context, and read receipts where supported.

Coverage? +

Coverage depends on carrier support, device settings, region, and messaging client. The checker returns a route-planning signal so teams can segment RCS-ready numbers from SMS fallback numbers.

Apple support? +

Apple support depends on iOS version, carrier, region, and user settings. Treat RCS detection as a campaign routing signal and keep SMS fallback available.

Is this an RCS availability checker and bulk RCS checker?
Yes. The RCS availability checker (also called a bulk RCS checker) detects which numbers in your CSV are RCS-capable — so you can route to RCS where available and fall back to SMS for the rest.
Do you offer an RCS verification API?
Yes. The RCS verification API returns RCS-enabled status per number, integrated into the same Carrier Lookup API. Use it inside signup and campaign-prep workflows.
