Update your GST registration on the Indian GST Portal first, wait until the government record and certificate show the correct information, then update the tax profile in each marketplace seller account separately. Changing a marketplace profile does not amend your GST registration, and changing a GSTIN does not alter product-level HSN or Product Tax Code settings. After both updates, verify the legal name, GSTIN, state, addresses, invoices, credit notes and tax reports. The exact menu for an existing marketplace account can differ from its public registration guide, so use the logged-in tax settings or the platform’s current Seller Support process when a self-service edit is not shown.
What GST details can change on a marketplace account?
“GST details” covers several independent records. Identify each change before editing anything, because a GSTIN, a business address and a product tax classification are maintained in different systems and may require different evidence.

| Principal place of business | GST Portal, marketplace business profile and sometimes fulfillment settings | Submit the appropriate core amendment, then change the registered and operating addresses in the marketplace | Amended certificate and the address documents requested by the platform |

| Pickup, warehouse or fulfillment location | Marketplace logistics settings | Change each active location separately; do not assume the GST address edit changes pickup settings | Address proof or platform-specific location approval |
| HSN, tax rate or Product Tax Code (PTC) | Individual listings or catalog feed | Correct the listing-level classification after the account update | Correct HSN/rate decision and the marketplace listing template or PTC value |
Make a short change list with the old value, the new value, the effective date and the system that owns it. This prevents the common mistake of changing only the GSTIN while leaving an outdated pickup address or product tax code active.
Which record should I update first: the GST Portal or the marketplace?
Update the GST Portal record first. Once the amended government record and certificate are available, update every marketplace seller account separately; marketplaces generally do not synchronize a GST amendment automatically.

For a non-core amendment, the Goods and Services Tax Portal manual states: “Amendment to Non-Core fields or fields other than Principal Place of Business does not require approval by the Tax Official.” The amended information is updated automatically in the taxpayer database after electronic submission. That government-side update still does not rewrite an Amazon, Flipkart, Meesho or other marketplace profile.
Use the amended certificate as the reference value when entering the marketplace data. If a platform asks for a GSTIN before the portal amendment is complete, do not enter a provisional number or a spelling that differs from the certificate; resolve the government record first and keep the acknowledgement for the support case.

How do I amend GST details on the GST Portal?
The portal workflow depends on whether the changed field is non-core or core. Keep the acknowledgement reference number (ARN) and the amended registration certificate after submission.
Amend non-core fields
- Sign in to the GST Portal with the taxpayer credentials.
- Open Services > Registration > Amendment of Registration Non-Core Fields.
- Select the tab containing the changed information, such as trade name, authorised signatory, contact information or another non-core field.
- Replace the old value with the value supported by your records and enter the reason for the amendment.
- Save the form, complete the declaration and submit it electronically using the available authentication method.
- Record the ARN or acknowledgement and download the amended registration certificate when it is issued or becomes available.
The portal manual’s no-approval statement applies to non-core fields or fields other than the principal place of business. It does not mean every amendment is instant in every circumstance, so retain the submission evidence and check the application status if the certificate does not update.
Handle core changes separately
A principal-place-of-business change, a legal-name change or a change in constitution can follow a different review path from a non-core edit. Use the current amendment form shown in your GST Portal account, provide the requested supporting documents and wait for the applicable review or approval. Do not copy the non-core menu path or assume that an automatic update applies.
When the core amendment is approved, compare the new certificate with the intended legal name, GSTIN, state and address character by character. A marketplace may reject a document when punctuation, state codes or the registered entity name do not match, even if the underlying change is correct.

What should I prepare before changing the marketplace tax profile?
Prepare the government-side evidence and an inventory of every marketplace location before opening a support case. A complete packet reduces back-and-forth when the platform’s self-service option is unavailable.
- The amended GST registration certificate, showing the current GSTIN and registered details.
- The GST Portal ARN or acknowledgement for the amendment.
- The previous and new values, including the effective date and the reason for change.
- A list of marketplace seller IDs, legal entities, states, pickup addresses, warehouses and fulfillment locations affected.
- Screenshots of the current tax profile and any error or verification message.
- The listing SKUs or ASINs whose HSN, rate or PTC may also need review.
- Copies of support case numbers and the date each update was submitted.
Use the same spelling, spacing and state designation as the amended certificate. Keep a private change log with the person who submitted each edit and the confirmation received; it is useful when invoices and reports are generated by more than one marketplace.
How do I change the GST number on an Amazon.in seller account?
Amazon describes a GSTIN as a 15-digit government-issued code and says GST verification can take up to 72 hours. Its public seller guide explains entering a GST number during registration, verifying the GSTIN and uploading the GST certificate if verification fails, but it does not establish a permanent click path for replacing the GSTIN on every existing account.
Use the logged-in tax controls first
- Sign in to the relevant Amazon.in Seller Central account, not a buyer account or a different seller entity.
- Open the tax, business-information or KYC area visible in your current account. Labels can change, so use the account’s current navigation rather than an old screenshot.
- Replace the GSTIN and matching legal or trade details with the values on the amended certificate.
- Upload the amended GST certificate if the form requests documentary verification.
- Submit the change and save the confirmation, case number or pending-verification status.
- Allow the stated verification window; Amazon’s registration guidance says verification can take up to 72 hours. Check the status after that period and respond to any request for a clearer certificate or additional evidence.
When no edit button is available
Open Seller Support from the logged-in seller account and ask for the current amendment route for an existing GSTIN or legal-identity change. Include the seller ID, the old and new GSTIN, the amended certificate, the ARN and a concise explanation of the change. Do not create a second seller account merely to bypass a pending amendment unless Amazon’s support team explicitly instructs you to do so; duplicate accounts can create separate tax and fulfillment records that are harder to reconcile.

How do I update GST details on Flipkart, Meesho or another marketplace?
Complete the GST Portal amendment first, then sign in to each seller portal and look for Tax Information, GST, Business Details or KYC. Flipkart, Meesho and other marketplaces can use different labels, document lists and approval queues, so confirm the current route in the platform’s own support channel.

If the portal shows no tax-edit control, contact support with the evidence packet. A marketplace support agent may need to perform an account-level change, and the exact requirements can differ for a GSTIN replacement, a state change, a legal-name amendment or a new pickup location.
Do I need to change the Product Tax Code or HSN after updating GST?
Yes, when the product’s tax classification or rate changed. A GSTIN is an account-level registration; Amazon’s Product Tax Code (PTC) is a product or listing-level setting. Updating one does not update the other.
Change a PTC for one Amazon listing
- In Seller Central, open Menu > Inventory > Manage All Inventory.
- Search for the SKU or ASIN that needs correction.
- Select Edit listing, then open Advanced View or All Attributes.
- Open Offer and find Product Tax Code.
- Select the correct PTC, save the listing and finish the edit.
- Recheck the listing after processing and verify that the tax code shown is the intended one.
Apply PTC changes in bulk
For many listings, use Amazon’s listing-loader spreadsheet and follow the current template instructions. Amazon says bulk PTC changes may take up to eight hours to reflect. Keep the submitted file and a list of affected SKUs so you can compare the completed catalog with the intended HSN and rate classification.
Review HSN and PTC values whenever a product is reclassified, a GST rate changes or a catalog is copied to a new marketplace. A correctly verified GSTIN cannot compensate for a wrong product tax code, and a corrected PTC cannot repair an account-level GSTIN mismatch.
How do I verify that the update actually worked?
Verify the account, operational locations and outputs separately. A green GSTIN verification badge is only one checkpoint.
- Account profile: Confirm the GSTIN, legal name, trade name where applicable, state and registered address against the amended certificate.
- Pickup and fulfillment: Open every active warehouse, pickup and fulfillment location and check that the state and address are current.
- Listings: Sample products across different tax categories and confirm the HSN or PTC values, especially those changed during the GST amendment.
- Invoices and credit notes: Review documents generated after approval for the legal name, GSTIN, place-of-supply information and address displayed by the marketplace.
- Reports: Compare tax reports and GST/TCS data with the seller ledger for the first reporting period after the change.
- Evidence: Save screenshots, approval notices, the amended certificate, the ARN and all support case numbers.
Use a newly generated document or report for the check; an old invoice may retain the details that were valid when it was issued. If a new document still carries the old details, stop treating the profile badge as proof of completion and open a correction case with the marketplace.

Why is my GSTIN verified but my invoices still show the old details?
Verification and document generation can be separate workflows. The account may have accepted the GSTIN while an invoice template, a seller-entity record, a pickup location or a listing feed still contains the previous value.
| Symptom | Likely area to inspect | Action |
|---|---|---|
| Profile shows the new GSTIN, but a new invoice shows the old legal name | Seller-entity or invoice profile | Capture both screens and ask Seller Support to synchronize the invoicing identity; include the amended certificate and approval reference |
| Invoice has the new GSTIN but the old address | Registered address or pickup/fulfillment location | Check each location record and request correction for the affected state or warehouse |
| Only some SKUs show the old tax treatment | Listing HSN or PTC | Correct the individual or bulk listing values and allow the marketplace’s stated processing time |
| Tax report and invoice disagree | Report-generation period or pending data refresh | Save the report and invoice, identify the transaction dates and ask support which record is authoritative for correction |
| Verification remains pending beyond the stated window | Document quality, mismatch or review queue | Check the certificate image, legal-name spelling and GSTIN digits, then reply to the open case rather than submitting multiple conflicting edits |
Do not silently alter your own copies of marketplace invoices. Preserve the originals, document the discrepancy and obtain the platform’s correction instructions so your records and the marketplace ledger remain traceable.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Is AWS Marketplace the same as Amazon.in Seller Central?
No. AWS Marketplace India is a separate service with its own tax settings. AWS says sellers must update changed tax information on its Tax Settings page because those details are used for marketplace tax invoices and e-invoices.
Use AWS Marketplace instructions only for the AWS seller account. Do not assume that changing Amazon.in Seller Central updates AWS Marketplace, and do not apply a retail-marketplace support path to an AWS tax-settings record. For each service, verify the resulting invoice and e-invoice data after the tax profile is accepted.
How do the government and marketplace workflows differ?
The following comparison shows why one successful edit does not complete the entire job.
| Question | GST Portal amendment | Marketplace profile update | Listing tax update |
|---|---|---|---|
| What does it control? | Government registration record and certificate | Seller account identity used by that platform | Tax classification for a product or SKU |
| Who operates it? | Goods and Services Tax Portal | Each marketplace separately | Marketplace catalog or listing tools |
| Can it update another system automatically? | No automatic marketplace synchronization should be assumed | No change to the GST Portal or other marketplaces | No change to the account GSTIN |
| Approval behavior | Non-core amendments are described as not requiring Tax Official approval; core changes can follow a different review path | Verification or support review depends on the platform | Individual edits may save directly; bulk processing can take time |
| Evidence to retain | ARN, acknowledgement and amended certificate | Submission confirmation, approval and support case number | Listing export, upload file and post-processing check |
How long should the complete update take?
There is no single end-to-end deadline because the government amendment, marketplace review and catalog refresh are separate queues. Amazon’s public guidance says GST verification can take up to 72 hours. Amazon also says bulk PTC changes may take up to eight hours to reflect. Treat those as platform-stated processing windows for those specific tasks, not as a promise that an entire GST amendment will finish within the same period.
Plan the work in checkpoints: submit the GST amendment, wait for the current certificate, submit each marketplace change, wait for account verification, then allow listing and report systems to refresh. Record the submission time for every checkpoint so a support agent can distinguish a normal processing delay from a mismatch or failed upload.
What are the most common mistakes and how can I recover?
- Editing the marketplace first: Finish the GST Portal amendment and use the amended certificate as the source of truth.
- Changing only the GSTIN: Review legal name, state, registered address, pickup locations and authorised-signatory details as separate fields.
- Assuming verification changes listings: Inspect HSN and PTC values and update affected SKUs.
- Using an old menu path: Follow the controls visible after logging in and ask the platform for the current route when the public registration guide does not cover existing accounts.
- Uploading a mismatched certificate: Check every GSTIN digit, entity name, state and address before submission.
- Submitting duplicate conflicting requests: Keep one support case per account-level change where possible and reply to the open case with corrected evidence.
- Ignoring operational locations: Update warehouse, pickup and fulfillment records that drive invoice addresses.
- Failing to test outputs: Verify a new invoice, credit note or report after approval and retain the evidence.
What does a business-address change look like in practice?
Suppose the principal place of business moved and the seller also uses two marketplace pickup locations. The safe sequence is:
- Submit the applicable core amendment on the GST Portal and retain the ARN.
- Wait for the amended certificate showing the new principal address.
- Update the registered business address in each marketplace seller account and attach the certificate.
- Change both pickup or fulfillment locations if they are affected; these records may have separate approval controls.
- Check the account profile, a newly generated invoice and the next tax report for the new address and GSTIN.
- Review product tax classifications only if the address change also reflects a change in state, registration or applicable tax treatment; do not alter PTC values without a classification reason.
This sequence keeps the government record, seller identity, logistics locations and product settings distinct while still allowing you to reconcile them at the end.
Frequently Asked Questions
Can I use the GST Portal acknowledgement before the amended certificate is available?
Use the acknowledgement to track the amendment and to explain a pending change to marketplace support, but follow the platform’s document rule for final verification. If the marketplace requires the amended certificate, wait for that document or ask support what interim evidence it accepts rather than uploading an unrelated older certificate.
What if I have more than one GST registration or seller entity?
Map each GSTIN to the correct marketplace seller ID, state and pickup locations before submitting edits. Updating one seller account does not establish that another account or registration has been changed, so reconcile them one by one.
Will old marketplace invoices be regenerated automatically after the GST update?
Do not assume they will be. Preserve the original documents, identify the affected transaction period and ask the marketplace whether it can issue a correction or explanatory document under its current process.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
How can I prove when the new GST details became active?
Keep the GST Portal ARN, the amended certificate issue or download record, marketplace approval messages and dated screenshots of the tax profile. Together they show the sequence and help support staff identify which invoices or reports were created before or after the change.
Should I change a product tax code just because the business address changed?
Not automatically. Change the HSN or PTC only when the product’s tax classification or rate is affected; an address-only amendment is an account or location change, not evidence by itself that every product classification is different.
