Use the GST Portal’s Search Taxpayer tool to inspect an existing GSTIN or UIN, and use Track Application Status with your application reference number (ARN) to follow a submitted registration application. Updating business information depends on the field: a principal or additional place of business requires a core amendment and tax-officer approval, while eligible signatory and stakeholder changes use the non-core amendment form and are automatically approved after successful filing.
The two status checks and the two amendment routes are separate. Choosing the wrong menu can leave an address change unfiled or send you looking for an application that is not linked to the public taxpayer search.

It helps to decide which question you actually need answered before opening the portal. “What details are attached to this GSTIN?” points to the taxpayer search. “What is happening to the application I submitted?” points to application tracking. An amendment is a third task: it changes information in an existing registration and uses one of the amendment menus. These tools may all relate to GST registration, but they do not show the same record or serve the same purpose.
Check an existing GST registration with Search Taxpayer
The GST Portal provides a pre-login taxpayer search. You can use it to check the registration profile associated with a GSTIN or UIN without signing in.
Steps to search a GSTIN or UIN
- Open the GST Portal and select Search Taxpayer.
- Choose the search option for GSTIN/UIN.
- Enter the 15-character GSTIN or the applicable UIN and complete the displayed verification code.
- Submit the search and review the taxpayer profile returned by the portal.
The pre-login result can show the GSTIN or UIN, legal name, trade name, effective date of registration, constitution of business, principal place of business, cancellation date where applicable, and details of returns filed. The portal indicates that additional data is available after login.
Free tools Windows power users keep installed
One-click scans. No signup required.
What this result tells you
The search confirms what information is attached to the identifier at the time you look it up. Compare the legal name, trade name, constitution and principal address with the invoice, vendor record or other document you are checking. A cancellation date, if displayed, is important: it means the registration has a recorded cancellation event, rather than simply being an active registration with no changes.
Use the result as a profile check, not as a substitute for the source document you are validating. For example, a customer or supplier check may involve comparing the returned legal name and address with the business information on an invoice. If the profile does not match, note exactly which field differs; this can help you ask the taxpayer to confirm or correct its registration particulars. The portal search shows the data associated with the identifier, but it does not itself amend inaccurate information.
This public lookup is not a certificate download and does not show every account-level detail. For a fuller view of your own registration, sign in to the taxpayer account and use the relevant registration and certificate menus.
Track a submitted registration application with the ARN
If you have filed a new registration application and want to know what happened to it, use the application’s ARN rather than Search Taxpayer.
Quick wins for a faster PC:
Scan for outdated or missing drivers - takes under a minuteDriver Scan →Clear out junk files and repair common Windows errorsFree Scan →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Steps to track the application
- Sign in to the GST Portal with the taxpayer credentials used for the application.
- Open Services > Registration > Track Application Status.
- Enter the ARN from the filing acknowledgement and provide any other fields the portal requests.
- Submit the search and read the current status, notices or next action shown for the application.
Keep the ARN acknowledgement available. Entering a GSTIN into the taxpayer search will not reliably show a pending application, particularly when no GSTIN has been issued yet.
The ARN is useful because it identifies the filed application rather than the taxpayer profile. Keep the acknowledgement with your business records after submission, and use the ARN shown there when you return to check progress. If a colleague, accountant or authorized signatory is helping with the filing, make sure the person responsible for monitoring the application can locate that acknowledgement and access the relevant account.

Do not assume a universal decision time
Official material establishes that some registration and amendment matters involve review by a tax officer, but it does not establish one current processing period that applies to every amendment type, state or jurisdiction. Treat any date shown in your account or correspondence as the operative information for that application. If the portal asks for a reply or additional document, respond through the prescribed workflow instead of relying on an informal estimate.
This distinction matters particularly for core amendments: submission is not the same as approval. Do not plan around an assumed number of days or treat a submitted acknowledgement as proof that the amended information has been accepted. Check the application record for its current status and any communication about the next step.

Classify the business detail before changing it
Before opening an amendment form, determine whether the field is core or non-core. The classification controls the menu path, whether an officer must approve the change and whether the field is editable in that form.
| Change you need | Portal route | Approval treatment | Important limitation |
|---|---|---|---|
| Principal place of business | Services > Registration > Amendment of Registration Core Fields | Requires tax-officer approval | Do not use the non-core form for an address |
| Additional places of business | Services > Registration > Amendment of Registration Core Fields | Requires tax-officer approval | The core category covers additional places other than a change of state |
| Eligible authorized-signatory details | Services > Registration > Amendment of Registration Non-Core Fields | Automatically approved after successful filing | The exact fields available depend on the account and portal rules |
| Eligible stakeholder details, such as promoters, partners or karta | Services > Registration > Amendment of Registration Non-Core Fields | Automatically approved after successful filing | Follow the verification and authentication prompts |
The GSTN Welcome Kit for New Taxpayers describes principal and additional places of business as core amendment details. It also states: “Amendment to non-core fields in GST registration does not require approval of any Tax Officer or visiting the Tax Department.” That statement applies to eligible non-core fields, not to an address change.
Think of the choice as a field-based decision, not as a preference for the faster-looking option. First name the precise detail you need to change; then choose the route that includes that field. The fact that a non-core filing is automatically approved after successful filing does not make every registration detail non-core, and it does not make a field editable in that form if the portal excludes it.
The distinction also clarifies what “approval” means here. A core amendment is submitted for tax-officer review. An eligible non-core amendment does not require an officer’s processing after successful filing, but it still has to pass the portal’s required validation and authentication. In either case, save the filing acknowledgement and use the portal record to verify what happened next.
Change a principal or additional business address
A move, correction or other change to the principal place of business belongs in a core amendment. The same route is used for additional places of business covered by the core amendment process.
Core-amendment procedure
- Sign in to the GST Portal.
- Select Services > Registration > Amendment of Registration Core Fields.
- Open the section for the principal place or additional place of business.
- Update the address and any related information requested by the form.
- Upload the supporting material requested for the new or corrected premises, if the portal asks for it.
- Review the complete amendment application, complete the required declaration and submit it using the authorized signatory’s permitted verification method.
- Save the acknowledgement and ARN generated for the amendment.
The amendment is not complete merely because the address appears in a draft or because the application has been submitted. A core amendment requires tax-officer approval. Monitor the application and respond to any portal notice or request for clarification.
Before submitting, review the address in the context of the whole application. Make sure you selected the principal-place or additional-place section that corresponds to the premises, and check that the information entered matches the documents you are using to support the change. The portal’s form and prompts determine what information or supporting material is required for your particular filing; do not assume that an attachment is unnecessary simply because another taxpayer’s amendment used different documents.

Changing states is a special case
The GSTN materials identify the principal place and additional places of business as core details, while expressly describing additional-place changes other than a change of state. Do not assume that moving a business registration from one state to another can be handled as an ordinary address edit. A state change can affect the registration itself and may require a different registration action under the applicable GST rules.
If the proposed move crosses a state boundary, pause before treating it as an address correction in the ordinary core-amendment workflow. Confirm the appropriate registration action for the circumstances rather than submitting an amendment that does not fit the change. This is one of the situations where a GST practitioner or tax-accounting professional may be useful if you are unsure how the move affects the registration.
Legal-name changes need field-specific care
Legal-name amendments are not identical in every circumstance. The GST Portal’s registration guidance contains conditions for legal-name updates and directs certain legal-name changes through the core amendment route. Check the eligibility and supporting-document requirements displayed for your account before filing; do not treat every name change as a simple spelling correction or assume that all cases receive the same treatment.
In particular, distinguish the legal name from a trade name when you identify the field that needs correction. The public taxpayer profile can display both, but seeing the two separately does not mean they follow the same amendment treatment. Use the field labels and eligibility instructions in the relevant portal form, and avoid changing one field as a workaround for a problem in another.
Change eligible non-core details
Non-core amendments are intended for fields that do not require a tax officer’s decision. Examples in the official tutorial include authorized-signatory information and stakeholder details such as promoters, partners or a karta.

- Sign in to the GST Portal using the taxpayer account.
- Go to Services > Registration > Amendment of Registration Non-Core Fields.
- Select the section containing the detail to be changed.
- Enter the new information exactly as it should appear in the registration particulars.
- Attach any document the portal requires for that field.
- Review the declaration and submit the amendment.
- Complete the electronic verification or authentication requested for the authorized signatory.
- Save the acknowledgement and submitted application reference.
The official tutorial says that a successfully filed non-core amendment is automatically approved and reflected in the registration particulars without processing by a tax official. “Successfully filed” means the form passed the portal’s required validation and authentication; a saved draft or an incomplete verification is not an approved amendment.
Because approval follows successful filing for eligible non-core changes, the important practical checkpoint is completion of all required steps, not simply entering the updated value. Review the form before submission, complete the signatory’s requested verification, and keep the acknowledgement. Afterward, check the registration particulars to confirm that the change is reflected. If it is not, inspect the submission record and any validation message rather than assuming that saving the form completed the amendment.
If the field is missing from the non-core form
Do not force the change into another field or use a free-text explanation as a substitute. A field that is unavailable in the non-core application may be a core field, may require a different document or may not be editable under that amendment type. Recheck the core-amendment menu and the instructions shown for the specific field.
This is also a reason to classify the change before beginning: if you spend time completing the wrong form, the underlying registration detail remains unchanged. The portal’s available sections and prompts are the useful guide to the eligible fields for the account; if the route remains unclear, seek advice rather than guessing at a substitute field.

Download the amended registration certificate
Filing an amendment and receiving an updated certificate are separate steps. After the amendment has been processed and an amended certificate is issued, retrieve it from the certificate menu.
- Sign in to the GST Portal.
- Select Services > User Services > View/Download Certificates.
- Review the certificates listed in chronological order.
- Open or download the amended registration certificate associated with the completed amendment.
The official tutorial says an amended registration certificate is displayed when registration details have been amended. If you can see the submitted amendment but no amended certificate, check whether the application is still awaiting core approval or whether the filing has not completed the required verification.
Do not treat the public taxpayer result and the certificate list as interchangeable. Search Taxpayer is useful for checking the public profile associated with the GSTIN or UIN; View/Download Certificates is the account menu for retrieving an issued certificate. For a completed change, use the certificate menu to locate the amended certificate, and review the displayed taxpayer profile separately if you also need to confirm what is publicly shown.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Troubleshoot common status and amendment problems
The GSTIN search returns no result
- Check every character of the GSTIN or UIN, including the state code and final checksum character.
- Make sure you are using Search Taxpayer, not the application-tracking screen.
- If the entity is still applying for registration, use the ARN in Track Application Status instead.
- For a recently filed amendment, allow the portal record to update and then check the registration profile again.
If you are checking a third party, verify that you were given the GSTIN or UIN rather than an application ARN. Those identifiers answer different questions. If the identifier is for an existing registration, return to the taxpayer search and check the entry carefully; if it identifies an application, go to the tracking workflow.
The address cannot be edited
This is expected if you opened the non-core form. Principal and eligible additional-place addresses must be handled through Amendment of Registration Core Fields, where an officer reviews the filing.
The non-core amendment is not showing as approved
- Confirm that the authorized signatory completed the requested electronic verification.
- Check whether the submission produced an acknowledgement rather than remaining a draft.
- Review the registration particulars after signing out and back in.
- Look for a validation message or document request in the application record.
The certificate has not changed
Check View/Download Certificates rather than relying only on the public taxpayer search. A core amendment may still be awaiting officer approval, and a filed amendment does not itself prove that an amended certificate has been issued.
You are unsure whether a change is core or non-core
Start with the exact field, not the type of business event. A change involving a business address is not eligible for the non-core address form; use the core amendment route for the principal place and covered additional places. Signatory and stakeholder information are examples of eligible non-core changes, but eligibility is determined by the field and the portal’s current prompts. If the field does not appear where expected, do not assume that a different field is an acceptable substitute.
Prepare before you file
- Identify the exact field and decide whether it is core or non-core.
- Keep the GSTIN/UIN for a profile lookup and the ARN for application tracking.
- Use the legal name and address format supported by your documents.
- Have the authorized signatory available for verification and authentication.
- Save the acknowledgement after submission.
- For a core change, monitor for officer communication and answer through the GST Portal.
- After processing, retrieve the certificate through Services > User Services > View/Download Certificates.
A quick pre-filing check can prevent confusion later: confirm whether you are checking a taxpayer profile, following an application or changing an existing registration; retain the matching identifier; and open the amendment route for the field you actually need to update. After filing, keep the acknowledgement and distinguish a draft, a submitted amendment, an approved or automatically processed change, and an issued certificate. These are different milestones.

You may be able to complete a straightforward non-core amendment yourself. Consider asking a GST practitioner or tax-accounting professional to review the filing when the change involves a relocation, multiple premises, a legal-entity or name change, conflicting records, a state-related issue or a notice from a tax officer. Professional assistance is optional; it does not remove the need to use the correct GST Portal route or retain the official acknowledgement.

Frequently Asked Questions
How can I check the details of a taxpayer registered under GST?
Use the GST Portal’s pre-login Search Taxpayer function and search by GSTIN or UIN. The result can show the identifier, legal and trade names, effective registration date, constitution of business, principal place of business, cancellation date where applicable, and details of returns filed. Additional data is available after login.
How do I track a GST registration application?
Sign in and go to Services > Registration > Track Application Status. Use the ARN from the filing acknowledgement. A GSTIN search is a profile lookup and is not a substitute for tracking an application, particularly before a GSTIN has been issued.
Can I change my business address through the non-core amendment form?
No. The GST Portal’s non-core amendment tutorial says a business address cannot be amended through that application. Use Services > Registration > Amendment of Registration Core Fields for the principal place and covered additional places of business. Core amendments require tax-officer approval.
Which details can be updated as non-core fields?
The official tutorial gives authorized-signatory information and stakeholder details, including promoters, partners or a karta, as examples. The exact eligible fields depend on the account and portal rules. A successfully filed non-core amendment is automatically approved without tax-officer processing, but required validation and authorized-signatory authentication still need to be completed.
How long does a core amendment take to be approved?
The official materials establish that core amendments require tax-officer approval, but they do not provide a universal current processing time for every amendment type and jurisdiction. Check the application record and any portal correspondence for the status and next action; do not rely on a general estimate.
Where can I download an amended GST registration certificate?
After an amended certificate has been issued, sign in and select Services > User Services > View/Download Certificates. Certificates are listed chronologically. Filing an amendment and having an amended certificate available are separate steps.
Does every legal-name change use the same amendment route?
No. The GST Portal registration guidance sets conditions for legal-name changes and directs certain changes through the core amendment route. Check the eligibility and supporting-document instructions displayed for your account; do not assume every name change is treated identically.
The Bottom Line
Use Search Taxpayer for an existing GSTIN or UIN, and Track Application Status with the ARN for a submitted application. For business-detail changes, classify the field first: addresses use the core amendment route and require tax-officer approval; eligible signatory and stakeholder details use the non-core route and are automatically approved after successful filing. Retrieve an amended certificate separately through Services > User Services > View/Download Certificates.
