This article explains how KAST verification works, what documents may be required, how verification levels unlock additional features, and what to do if your verification is delayed or rejected.

What Is Identity Verification on KAST?

Identity verification is the process KAST uses to confirm that you are the person opening and using the account.

As a regulated financial platform, KAST performs verification checks to help protect customers, prevent fraud, and comply with financial regulations.

Depending on your location, and the products you want to use, KAST may ask you to provide:

• Personal information, such as your name, date of birth, and address
• A government-issued ID, such as a passport, national ID card, or driver's license
• A selfie or liveness check to confirm your identity
• Proof of Address documents
• Source of Funds documentation
• Additional supporting information, if required

The information and documents requested will vary depending on your verification level and account activity.

How Does KAST Verification Work?

KAST uses a tiered verification system. As you complete additional verification levels, you unlock more products, features, and account capabilities.

You don't need to complete every level immediately. Most users begin with Level 1 and Level 2 verification, then upgrade to Level 3 when they want to access additional products that require enhanced verification.

If a feature requires a higher verification level, KAST will guide you through the additional steps needed to upgrade your account.

How Do I Complete Level 1 Verification?

Level 1 verification is completed during account registration and gives you access to the KAST app. Once verified, you can explore available products and features, such as viewing eligible cards and account options, although most financial services remain locked until you complete higher verification levels.
