What is GST ARN and How to Check GST ARN Status?

Goods and Services Tax (GST) registration is mandatory for many businesses in India. When a taxpayer applies for GST registration or submits certain applications on the GST portal, they receive a unique number called an Application Reference Number (ARN). This number plays an important role in tracking the progress of your GST application.

What is GST ARN?

GST ARN is a unique identification number generated on the GST portal when a taxpayer submits an application successfully. This number helps track the status of applications such as GST registration, amendments, refunds, or other GST-related requests.

Once your application is submitted on the official portal of the Goods and Services Tax Network, the system automatically generates the ARN and sends it to your registered email ID and mobile number.

In simple terms, GST ARN acts as a tracking ID for your GST application.
