# Android phone number verification set up

This guide will show you how to set up the Sinch Verification SDK for the first time.

## Register an Application

1. Register a [Sinch Developer account](https://dashboard.sinch.com/#/signup)
2. Set up a new Application using the Dashboard, where you can then obtain an **Application Key**.
3. Enable Verification for the application by selecting: **Authentication** > **Public** under **App** > **Settings** > **Verification**


## Add the Sinch library

The Sinch Verification SDK is available publicly on mavenCentral. To include it in your Android application, make sure your **project** level build.gradle file contains:


```text
buildscript {
    repositories {
        google()
        mavenCentral()
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}
```

Now, in your **module** level build.gradle file, you can add Sinch SDK as a dependency:


```text
dependencies {
    implementation 'com.sinch.android.sdk.verification:verification-all:*.*.*'
  }
```

If your application uses all the verification methods it's easiest to add the *verification-all* package. If you intend to use only specific verification types, you may include only their dependencies.

- verification-sms
- verification-flashcall
- verification-callout
- verification-seamless


### Example:

If your application relies only on SMS verification and doesn't use any other verification methods you should simply add:


```text
dependencies {
    implementation 'com.sinch.android.sdk.verification:verification-sms:*.*.*'
  }
```

The latest version of the SDK can be checked on [here](https://search.maven.org/search?q=com.sinch.android.sdk.verification).
