GST REG-02 explained: the acknowledgement for your application

GST REG-02 is the acknowledgement the GST portal generates when you successfully submit a registration application such as REG-01. It carries an Application Reference Number (ARN), which is your proof of filing and the key for tracking the application.

What REG-02 contains

REG-02 is system generated under Rule 8 of the CGST Rules. It is sent to the registered email and mobile number and can be downloaded from the portal. It records the ARN, the date and time of filing, the applicant's name, the form filed and the jurisdiction to which the application has gone.

Why the ARN matters

The date on REG-02 fixes the date of application. That date matters for two things: the officer's time limit to act, and the effective date of registration. If you applied within 30 days of becoming liable, registration is effective from the date of liability; otherwise it runs from the date of grant.

  • Track status under Services, Registration, Track Application Status
  • Quote the ARN in any correspondence with the jurisdictional office
  • Keep the PDF in your compliance records

Status values you may see

  • Pending for processing: with the officer, no action yet
  • Pending for clarification: a REG-03 notice has been issued and needs a reply in REG-04
  • Clarification filed: your reply is under review
  • Approved: REG-06 certificate is available
  • Rejected: a REG-05 order has been passed

If nothing happens

Rule 9 sets time limits for the officer to act. If the officer neither seeks clarification nor rejects the application within the prescribed time, the application is deemed approved and the GSTIN is generated by the system. Keep checking the status and your email, because a query issued late at night or a missed REG-03 can turn into a rejection if you do not reply in time.

Questions

REG-02 — FAQs

Is REG-02 the same as a GST certificate?+
No. REG-02 only confirms that the application was filed. The registration certificate is REG-06, issued after approval.
Can I start charging GST with only an ARN?+
No. You cannot issue tax invoices with a GSTIN until registration is granted, though you may later issue revised invoices for the period from the effective date of registration.
I did not receive REG-02 by email. What should I do?+
Log in with your TRN or credentials and check the application status. The ARN is shown on screen after submission and the acknowledgement can be downloaded from the portal.
How long is the ARN valid for tracking?+
The ARN stays linked to the application permanently, so you can use it to check the status, download the acknowledgement or refer to the application in a later dispute.
