GST ARN Status: Track Registration Application

When you submit a GST registration application on gst.gov.in, the portal generates an Application Reference Number (ARN). This is your tracking key until the officer either approves or rejects the application. Every applicant who has completed Part A and Part B of Form GST REG-01 receives an ARN, and the wait between submission and GSTIN allotment is where most confusion happens.

This guide explains what each ARN status means, how to check it, how long the process takes, and what to do if something goes wrong.

What Is an ARN in GST?

Featured Snippet: An ARN (Application Reference Number) is a 15-character alphanumeric code generated by the GST portal when you successfully submit Form GST REG-01 and complete mobile and email OTP verification. Format: AA/SSSS/YYYYYYY (two-letter state code, four-digit zone code, seven-digit serial number). You receive it via SMS and email. Use it to track your registration status at gst.gov.in under Services > Track Application Status. The ARN remains valid until a final decision (approval or rejection) is issued.

The ARN is not your GSTIN. It is a temporary reference that confirms the portal accepted your application. The GST Identification Number (GSTIN) is issued only after the proper officer approves the application, and it replaces the ARN as your permanent identifier.

ARN Format

The ARN follows a standard structure:

You will find the ARN in the acknowledgment displayed on screen after submission and in the confirmation SMS and email sent to your registered mobile and email address.

Post-Login Method

If you already have GST portal credentials (from a previous registration or a Temporary Reference Number):

1. Log in at gst.gov.in with your username and password.
2. Go to Services > Track Application Status.
3. Select Module: Registration.
4. Enter the ARN and click Search.

The post-login view may show additional details like the officer's name and office jurisdiction.

Using TRN (Temporary Reference Number)

If you saved a draft application but have not yet submitted Part B, you have a TRN instead of an ARN. A TRN tracks a draft, not a submitted application. To check TRN status, select "Login using TRN" on the registration page, enter the TRN and OTP, and continue editing or submit the application to generate an ARN.

What Each ARN Status Means

After you search by ARN, the portal shows one of these statuses:

Timeline: ARN to GSTIN

The processing time depends on your application's risk profile and whether Aadhaar authentication was completed.

Auto-Approval Under Rule 14A

Rule 14A of the CGST Rules (effective from November 1, 2025) introduced a dual-track processing system. Applicants identified as low-risk through the portal's data analysis receive automatic approval within 3 working days if the assigned officer does not act within that window. This applies to Aadhaar-authenticated applicants with a clean compliance history.

If you completed Aadhaar authentication during registration and your status still shows "Pending for Processing" after 7 working days, file a grievance on the GST portal under Services > User Services > Grievance/Complaint.

What to Do If Your Application Is Rejected (REG-05)

A rejection is issued in Form GST REG-05. The order states the reasons, which typically include: documents not matching (name on PAN versus business registration), address proof rejected, business activity description too vague, or failure to respond to REG-03 within the deadline.

You have two options:

Option 1: File a Fresh Application

There is no mandatory waiting period after rejection. You can submit a new Form GST REG-01 immediately with corrected documents. This is the faster route when the rejection was due to a fixable document issue.

Before reapplying:

• Read the REG-05 order carefully. Fix every issue it mentions.
• Get a fresh electricity bill or rent agreement if the address proof was rejected.
• If there was a name mismatch, get the underlying document (PAN, Aadhaar, or incorporation certificate) corrected first.

Option 2: Appeal Under Section 107

If you believe the rejection was incorrect and the officer ignored valid documents you submitted, you can appeal:

• Deadline: Within 3 months of the REG-05 order date (extendable by 1 month by the appellate authority).
• Where: On the GST portal under Services > User Services > My Applications > Appeal to Appellate Authority > Order Type: Registration Order.
• Attach: The REG-05 rejection order, a detailed written explanation, and all supporting documents.

Appeals are appropriate when the officer rejected despite a proper REG-04 reply. In practice, reapplying with corrected documents is faster than the appeal process for most applicants.

After Approval: Downloading Your GST Certificate

Once status shows "Approved," the portal sends your GSTIN and login credentials (User ID and temporary password) to your registered email. To download the certificate:

1. Log in to gst.gov.in with the credentials from the approval email.
2. Go to Services > User Services > View/Download Certificates.
3. Download Form GST REG-06, which is your GST registration certificate.

The certificate shows your GSTIN, legal name, trade name, principal place of business, effective date of registration, and the type of registration (Regular, Composition, or Casual).

Verify Your GSTIN

After receiving your GSTIN, verify it is correctly reflected in the public database:

1. Go to gst.gov.in > Search Taxpayer > Search by GSTIN/UIN.
2. Enter the 15-digit GSTIN.
3. Confirm your business name, address, registration date, and status show as "Active."

This verification is important when sharing your GSTIN with suppliers and customers, because they will check it before accepting your invoices for ITC claims.

Common Issues and Fixes

ARN not received after submission: Check your registered email's spam folder. If not found, go to Services > Track Application Status and search using your PAN instead of ARN. The portal also shows applications submitted against a PAN.

Status stuck on "Pending for Processing" beyond 7 days: File a grievance via the GST portal (Services > User Services > Grievance/Complaint). Include your ARN, submission date, and a screenshot of the status page. You can also contact the GST helpdesk at 1800-103-4786 (toll-free).

REG-03 received but cannot see it on portal: Log in using TRN or the credentials provided during Part A registration. Go to Services > Registration > Application for Filing Clarification. The REG-03 notice and reply option appear here.

"Validation Error" when checking ARN: Ensure you are entering the ARN exactly as received, no spaces before or after, correct case. If the ARN contains special characters, copy it from the original SMS or email.

Frequently Asked Questions

What is the difference between ARN and GSTIN?

ARN (Application Reference Number) is a temporary 15-character tracking code issued when you submit Form GST REG-01. It tracks your application until a decision is made. GSTIN (GST Identification Number) is the permanent 15-digit number issued after approval. ARN is for tracking; GSTIN is for filing returns, issuing invoices, and claiming ITC.

Can I file GST returns with an ARN before GSTIN is issued?

No. You cannot file GST returns, issue tax invoices, or collect GST using an ARN. You must wait for the GSTIN to be issued. Once approved, your registration is effective from the date mentioned in the certificate, and you file returns from that date onward.

How long does GST registration take after ARN generation?

With Aadhaar authentication and a clean application, 3 to 7 working days. Low-risk applicants under Rule 14A may get auto-approval in 3 working days. Without Aadhaar or with site verification, up to 30 working days. If a REG-03 clarification notice is issued, add 14 or more working days.

What should I do if my ARN status shows Pending for Clarification?

Log in to the GST portal and go to Services > Registration > Application for Filing Clarification. Read the REG-03 notice, prepare the requested documents, and submit your reply in Form REG-04 within 7 working days. Attach only the specific documents the notice asks for.

Can I apply again after GST registration rejection?

Yes. There is no waiting period. You can file a fresh Form GST REG-01 immediately after correcting the issues mentioned in the REG-05 rejection order. Alternatively, you can appeal within 3 months under Section 107 of the CGST Act if you believe the rejection was unjustified.

Is the ARN status check available without logging in?

Yes. Go to gst.gov.in > Services > Track Application Status > Registration. Enter your ARN and click Search. No login credentials are needed for this check.
