# Welcome

IDlayr verifies mobile phone numbers and SIM state through direct integration with mobile network operators. These docs cover platform concepts, per-product integration paths, the Enterprise Portal, and worked tutorials.

## Products

IDlayr products work directly with mobile network operators to answer questions that other identity signals can't: is this number reachable on a supported network, is the SIM behind it the same one as last week, is the device making this request really the one that holds the number. Each product is a single, well-scoped check that you can compose into the verification flow that fits your risk model.

[**Browse all products →**](/products/products.md)

The products are grouped into three families:

* [**Eligibility**](/products/eligibility.md) — pre-flight check, by phone number or by mobile IP address. Run before any verification.
* [**Number Verification**](/products/number-verification.md) — Secure SNA, Reverse SMS, Discovery.
* [**Risk**](/products/risk.md) — SIM Swap.

## Run a browser demo

Sandbox-mode demos that run entirely in the browser. No SDK, no device, no account required to try.

<table data-view="cards"><thead><tr><th></th><th></th><th data-hidden data-card-target data-type="content-ref"></th></tr></thead><tbody><tr><td><strong>Secure SNA</strong><br><code>Browser demo</code></td><td>Silent network authentication — verify the device's mobile number without a one-time code.</td><td><a href="https://secure-sna-demo.idlayr.com">https://secure-sna-demo.idlayr.com</a></td></tr><tr><td><strong>Discovery</strong><br><code>Browser demo</code></td><td>Silently discover the device's MSISDN and confirm it with the user before use.</td><td><a href="https://discovery-demo.idlayr.com">https://discovery-demo.idlayr.com</a></td></tr><tr><td><strong>SIM Swap</strong><br><code>Browser demo</code></td><td>Check whether a phone number's SIM has recently changed — pure backend call, no device needed.</td><td><a href="https://simswap-demo.idlayr.com">https://simswap-demo.idlayr.com</a></td></tr></tbody></table>

Reverse SMS is not available as a browser demo — the verification requires the user to send an SMS from their device. Try it via the Verify App below.

## Try it on your phone

The IDlayr Verify App lets you run live verifications across all products — including Reverse SMS — from your own iOS or Android device. Use the app to validate behaviour on real networks before integrating.

<table data-view="cards"><thead><tr><th></th><th></th><th data-hidden data-card-target data-type="content-ref"></th></tr></thead><tbody><tr><td><strong>Verify App for iOS</strong><br><code>App Store</code></td><td>Run Secure SNA, Reverse SMS, Discovery, and SIM Swap from your iPhone. Sandbox and production modes.</td><td><a href="https://verify-app.idlayr.com/redirect/app-store">https://verify-app.idlayr.com/redirect/app-store</a></td></tr><tr><td><strong>Verify App for Android</strong><br><code>Play Store</code></td><td>Run Secure SNA, Reverse SMS, Discovery, and SIM Swap from your Android device. Sandbox and production modes.</td><td><a href="https://verify-app.idlayr.com/redirect/app-store">https://verify-app.idlayr.com/redirect/app-store</a></td></tr></tbody></table>

## Enterprise Portal

The [web UI](/enterprise-portal/enterprise-portal.md) for managing projects, credentials, allowed networks, verification logs, and users.

## Using an AI assistant?

These docs are exposed as an [MCP server](https://docs.idlayr.com/help-center/ai-assistants) at `https://docs.idlayr.com/~gitbook/mcp`. Point Claude Code, Cursor, or any MCP-aware assistant at it and ask questions grounded in the live docs.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.idlayr.com/readme.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
