How to Check GST ARN Status After Applying

To check your ARN status, open the GST portal, go to Services → Track Application Status, select the Registration module, and enter the Application Reference Number issued when you submitted your registration form. You do not need to log in — which matters, because a first-time applicant has no GSTIN credentials yet. The status the portal returns tells you exactly one thing that you need to act on: whether the officer is waiting on you, or you are waiting on the officer.

Where the ARN comes from

GST registration is filed in two parts. Part A of Form GST REG-01 collects your PAN, mobile number and email address, verifies the last two by OTP, and hands you a Temporary Reference Number (TRN). The TRN is only a session key: it lets you log back in and finish Part B, which is where the real work happens — constitution of business, principal place of business, promoters and partners, authorised signatory, bank details and the supporting documents for all of it. The full sequence is covered in our walkthrough of the GST registration process online.

The Application Reference Number appears at the end of that second stage, once Part B has been submitted and signed with a DSC, e-sign or EVC. The portal issues an acknowledgement in Form GST REG-02 carrying the ARN, and sends the same reference to the mobile number and email address you verified back in Part A. Two things follow from that:

• A TRN is not an ARN. If all you have is a TRN, your application has not been submitted — Part B is still sitting as a draft, and the officer cannot see it. There is nothing to track yet.
• The ARN goes to the contact details entered in Part A, not to whoever happens to be handling the file. If a consultant filed on your behalf using their own mobile and email, the ARN went to them. Ask for it in writing rather than reconstructing it — it is the only handle you have on the application.

One ARN covers one application. Amendments, cancellation requests and revocation applications each generate their own ARN later on, and all of them are tracked through the same screen — you just pick the matching module. What follows deals specifically with a new registration ARN.

Checking ARN status without logging in

The tracker is deliberately available pre-login, because the person who most needs it is someone who does not yet have a GST account. The path is:

1. Open the GST portal home page.
2. From the Services menu, choose Track Application Status.
3. Set the module or application type to Registration.
4. Enter the ARN exactly as issued and complete the captcha.
5. Submit. The portal returns the current stage and the date it was reached.

The same page also accepts a submission-date search and, in the post-login version, lets an existing taxpayer see every application filed against their GSTIN. If you already hold a GSTIN and are tracking an amendment or a second-state registration, log in first — the post-login view lists your applications so you do not have to hunt for the reference number.

What each ARN status actually means

The registration pipeline reports a small, fixed set of stages. The useful way to read them is by asking who the ball is with.

Exact wording varies slightly between portal releases, and you may see intermediate labels such as a withdrawn or pending-for-order state on non-registration modules. The underlying logic does not change: the application is either with the officer, with you, or finished.

How long each stage should take

A straightforward application with no officer query is generally expected to be processed within about seven working days of ARN generation. Applicants who take the Rule 14A route — the optional simplified track for small, low-risk applicants, effective from 1 November 2025, which requires Aadhaar authentication of the primary signatory and at least one promoter — can be granted registration within three working days of ARN generation when the automated risk check is clear.

Two things stretch that. Failed or skipped Aadhaar authentication routes the application towards physical verification of the premises, which carries a longer processing window. And a REG-03 query effectively resets the clock: the officer gets a fresh review period running from the date your REG-04 reply is filed, not from the original submission date. An application that spends a fortnight in "Pending for Clarification" because nobody checked the tracker has burned that fortnight for nothing.

Responding to a REG-03 clarification notice

"Pending for Clarification" is the status that costs people their registration, almost always through inaction rather than a bad answer. When it appears, the notice itself is available on the portal against the ARN, and it will name specifically what the officer wants. Read it before you do anything else — REG-03 notices are usually narrow, and the fastest reply is one that answers the actual question rather than re-uploading everything.

You reply in Form GST REG-04, from the same tracker screen or from the dashboard if you are logged in with the TRN. Some practical points:

• Answer the query as framed. If the officer asks for a rent agreement plus an electricity bill in the landlord's name, send both, in that order, clearly labelled. Substituting a different document because it was easier to obtain is how a single query becomes two.
• Match names and addresses exactly. The single most common cause of a clarification query is a mismatch between the PAN name, the document, and what was typed on the form — an expanded initial, a missing "Private", a flat number written differently on the utility bill. Fix the form entry if the document is right; do not argue that they are obviously the same entity.
• Do not let the window lapse while you gather a perfect reply. A complete filing on the last day is fine; a missed deadline is fatal. If a document is genuinely unobtainable, say so in the reply with what you can provide instead, rather than filing nothing.
• Re-check the tracker after filing. The status should move to "Clarification filed – Pending for Order". If it has not moved a day later, confirm the submission actually went through — an unsigned or half-submitted REG-04 counts as no reply.

If the application is rejected

A rejection is recorded in an order in Form GST REG-05, and the order states the grounds. Read those grounds literally, because they are the checklist for your next attempt. In practice, rejections cluster around a handful of causes: document and form details that do not match, an address proof that does not establish a right to occupy the premises, an unclear or non-conforming photograph, incomplete promoter or authorised signatory details, and — most often of all — an unanswered REG-03.

There is no way to reopen a rejected ARN. The route forward is a fresh application, with the specific defect corrected. Before refiling, it is worth re-reading the registration walkthrough against your document set, and checking that anything you are copying from an existing entity — a PAN-linked name, a state code in a group GSTIN — is being reproduced correctly rather than from memory.

After approval: from ARN to a working GSTIN

When the status turns to Approved, the ARN has done its job. The portal issues a GSTIN along with a temporary username and password sent to the registered email address; you use those once to create your permanent credentials, after which the registration certificate in Form GST REG-06 is available for download from the dashboard.

Two checks are worth running immediately, before the number goes onto invoices or into a counterparty's master data:

• Check the structure of the number. The first two digits are the state code and the next ten are the PAN of the registered entity. If either does not match what you expect, raise it before you start billing. Our guide to the GSTIN format breaks down each position, and the GST state code list covers the first two digits.
• Confirm it resolves publicly. A newly issued GSTIN should return an active status with the right legal name, trade name, registration date and jurisdiction on a public search. Run it through the GST number search tool or an API call before your customers do.

That last check is not a one-off. Registration status changes over the life of a business — it can be suspended or cancelled, sometimes without the counterparty noticing, which is why a suspended GSTIN is a recurring problem in accounts payable rather than a rare one. If you are on the receiving end of someone else's freshly approved registration, the same discipline applies to them: verify the GSTIN when it is first supplied, and re-verify periodically thereafter. Programmatically that is a single call:

curl -H "x-api-key: YOUR_API_KEY" \

The response carries the legal name, trade name, registration date, constitution of business, jurisdiction and current status — which is what you actually want to store against a vendor record, rather than a screenshot of a portal page taken once at onboarding. There is a broader onboarding checklist in our guide to spotting a fake GST number.
