APOB for Amazon, Flipkart and Meesho sellers: how to add a marketplace warehouse to your GST registration, state by state

If you sell on Amazon, Flipkart, Myntra or Meesho and let the platform store your inventory, you will sooner or later be asked for a GSTIN of that state with the fulfilment centre listed on it. The seller dashboard usually calls it an APOB — an Additional Place of Business. Until it is done, inbound shipments stay blocked.

The request sounds like a platform formality. It is not. It comes straight from GST law: the place your goods are stored and supplied from is your place of business, and it must sit on a registration that belongs to you, in the state where it stands. The platform is only checking that you have done what the law already requires.

This guide takes the seller’s side of the screen: when you need a new GSTIN and when an amendment is enough, the order of work for a new state, what the marketplace gives you and what the officer may ask for, the FORM GST REG-14 filing step by step, realistic timelines, how to move stock without an invoice or e-way bill problem, and the mistakes behind almost every rejection. All of it is current as of September 2026.

Why the marketplace asks for an APOB before it will take your stock

When a fulfilment centre holds your inventory, three things are true at once. The goods still belong to you. They sit at an address you neither own nor rent. And when a customer orders, the supply is made from that address, on your invoice, under your GSTIN.

GST defines a place of business by what happens there, not by who holds the lease: any place from where business is carried on, where goods are stored or supplied, where books are kept, or where an agent acts for you. A warehouse full of your stock fits exactly. Section 25 of the CGST Act then requires registration in each state from which taxable supplies are made, and every address used under a registration must be declared on it.

So the platform is not enforcing its own invention. Every dispatch from that centre is a supply from a place of business, and if the place is missing from your certificate it is a supply from an undeclared address — a problem for the platform’s records as much as yours. Hence the check on your certificate’s annexure before an inbound appointment.

New GSTIN or just an APOB? The same-state test

Answer this first, with a one-line test: an additional place of business must be in the same state as the GSTIN it is added to. Registration is state-wise and the first two digits of your GSTIN are the state code, so nothing on a Karnataka registration can sit in Telangana.

Two smaller points follow. Extra registrations for separate places of business within one state are optional under Rule 11, so a second Karnataka warehouse needs no second Karnataka GSTIN. And a person selling goods through an e-commerce operator must register under Section 24 regardless of turnover, so threshold arguments that help a local shop rarely help a marketplace seller. If you are still choosing states, the second-state expansion checklist covers everything else that follows an address into one.

The full sequence for a new state, in order

Sellers get into trouble by doing these steps out of order. The chain is strict: you cannot add a warehouse to a GSTIN you do not have, and you cannot get a GSTIN without a principal place of business in that state.

1. Fix the principal place of business first. The warehouse cannot be your principal place of business — the platform’s consent covers its centre as an additional place only. You need your own address in the state, and most sellers take a virtual office: real commercial premises with an agreement in your business name, the owner’s NOC and a recent utility bill.
2. Apply for the state’s GSTIN in FORM GST REG-01. Part A takes PAN, mobile and email and returns a Temporary Reference Number valid 15 days. Part B carries business details, promoters, authorised signatory, the principal place of business with its possession proof, goods and services with HSN codes, and the Aadhaar authentication choice. Sign with a DSC if you are a company or LLP, otherwise by EVC, and note the ARN.
3. Clear verification. The officer approves within 7 working days under Rule 9, or 30 days where Aadhaar authentication was not done or physical verification is ordered. Many applicants are now also called for biometric Aadhaar authentication at a GST Suvidha Kendra by appointment. A query comes in FORM GST REG-03 and must be answered in REG-04 within 7 working days.
4. Collect the certificate and the warehouse papers together. Download FORM GST REG-06 from Services → User Services → View/Download Certificate, and in parallel pull the centre’s consent letter from the seller portal so the amendment goes in the same week.
5. File FORM GST REG-14 to add the centre as an APOB. A core-field amendment goes to an officer, who approves in FORM GST REG-15 within 15 working days under Rule 19.
6. Update the seller account. Add the new GSTIN against that state in the platform’s tax settings and upload the amended certificate. Create an inbound shipment only once the platform shows the centre as enabled.
7. Finish the housekeeping. Bank details within 30 days of grant or before the first GSTR-1, whichever is earlier (Rule 10A); certificate and name board at both addresses (Rule 18); a separate invoice series for the new GSTIN; the new state added to your returns calendar.

Documents the marketplace gives you, and what the officer will accept

The confusion here is genuine. You are filing two different addresses, with two different document sets, under one registration.

Amazon generates the warehouse documents from Seller Central; Flipkart, Myntra and Meesho typically email them on request through seller support. Either way, the letter names your legal entity and the specific centre, and it is that address — not the one on the platform’s website — that goes into the form.

The officer’s room to ask for more is narrow. CBIC Instruction No. 03/2025-GST dated 17 April 2025 directs officers to process applications on the documents listed in FORM GST REG-01, not to demand extras such as the owner’s PAN or Aadhaar, photographs of the premises or original physical copies, and not to raise irrelevant queries. Anything beyond the list needs prior approval from a Deputy or Assistant Commissioner. If a query asks for a rent agreement for a warehouse you do not rent, that instruction is your answer.

Filing FORM GST REG-14, step by step

An APOB is not a new application. It is an amendment to a registration you already hold, and it lives under a specific menu on the portal.

1. Read the consent letter before you open the portal. Note the building, unit or dock number, floor, road, locality, district and PIN exactly as printed. Almost every APOB query starts as an address mismatch.
2. Go to the amendment screen. Services → Registration → Amendment of Registration Core Fields, then the Additional Places of Business tab.
3. Declare how many places you are adding. Enter the number, then open the block for each. Three centres in one state go in one amendment, not three.
4. Enter the address and the activity. Type the address exactly as on the letter, set the nature of possession to consent or shared, and tick the business activity that applies — warehouse or depot, plus wholesale or retail if the letter supports it.
5. Upload the proof and give the date of change. Attach the consent letter and the warehouse address proof, and enter the date from which the place is used; Rule 19 expects the amendment within 15 days of it.
6. Verify and submit. Companies and LLPs sign with a Digital Signature Certificate under Rule 26; others can use EVC. An ARN is generated and can be followed under Track Application Status.
7. Collect the amended certificate. On approval in FORM GST REG-15 the amended FORM GST REG-06 downloads with the new place in its annexure. That annexure page is what the marketplace wants to see.

The same screen removes a place. When you exit a centre, delete it by amendment: a stale APOB produces returns and e-way bills that do not match where your stock is, and invites a verification visit for no benefit.

Timelines you can plan against

One timing rule is easy to get wrong in the other direction. Under Rule 10, apply within 30 days of becoming liable and the registration is effective from the date you became liable; apply later and it runs only from the date of grant. Sales made from a state before the effective date cannot be regularised afterwards.

Moving stock to the warehouse: distinct persons, invoices, e-way bills and ITC

Once the APOB is live, the next question is how the goods get there. Sellers often assume a delivery challan and a courier docket are enough. Once the stock crosses a state line, they are not.

Two registrations under the same PAN in two states are distinct persons under Section 25(4), and Schedule I treats a supply of goods between distinct persons in the course of business as a supply even though nobody pays you. Moving your own stock from a Karnataka GSTIN to a Haryana GSTIN is therefore a taxable supply:

• Raise a tax invoice from the sending GSTIN to the receiving GSTIN, with the Rule 46 particulars and a series belonging to the sending state.
• Charge IGST, since supplier and recipient are in different states. Value it on the basis your accountant applies between distinct persons, and stay consistent.
• Generate the e-way bill for the movement on the same invoice.
• Claim the input tax credit in the receiving state. The tax is not a cost; it moves the credit to the state where the sale will actually happen.

Sending stock into a marketplace centre that is an APOB on your own GSTIN in that state works the same way. The consignee is your registration in the destination state; the centre is simply an address on it. The marketplace is not the buyer at this stage — it becomes involved when a customer orders, collecting tax at source on that sale and reporting it, with the credit landing in the electronic cash ledger of the GSTIN the supply was made from.

One GSTIN, many warehouses in the same state

Marketplaces open centres in clusters, so once a state is live, the second and third centre there are much lighter work than the first.

• No new registration. Rule 11 makes a separate registration for another place of business in the same state optional, and for a seller it is usually the wrong choice: one GSTIN with several APOBs means one set of returns, two GSTINs mean two.
• No practical limit on APOBs. Add as many centres, returns centres and dark stores as you use, in one amendment where possible.
• Same-state movement is not a distinct-persons supply. Goods moving between two places on one GSTIN are not sold to anyone; they move on a delivery challan with an e-way bill where required.
• Rule 18 applies to every one of them. Certificate at the principal place and every additional place, GSTIN on the name board. At a marketplace centre that sits within the platform’s arrangements; at your own premises the obligation is yours.
• Books per place. Section 35 requires each place’s accounts to be kept there, subject to the electronic-records provisions — in practice, records producible for the state, not ledgers in a warehouse aisle.

What this actually costs

Start with what is free. There is no government fee for GST registration and none for a REG-14 amendment, so nobody should be invoicing you a “government fee” on an APOB. What you pay for, per state, is a real principal place of business and the paperwork that proves it:

• The address — commercial premises in the state on an agreement in your business name, with the owner’s NOC and a recent utility bill. The only recurring cost of a state you have entered.
• Stamp duty and notarisation or registration of that agreement, at the rate the state sets. It varies widely and is paid once per agreement.
• A Class 3 DSC for a company or LLP, from a licensed certifying authority — indicatively around ₹1,000–2,500 for two years.
• Professional fees if you use a CA or consultant — a few hundred to a few thousand rupees, and not a government charge.

SimplySetup’s GST Registration package covers the address side of that list at ₹799 a month billed annually, plus 18% GST: the address, the rent agreement, the owner’s NOC and utility bill kit, the name board, mail handling and filing support. The plainer Business Address plan at ₹399 a month is deliberately not the one to buy here, because it carries no rent agreement or NOC and without those there is no GST file. Premises are owned by SimplySetup or an exclusive partner, so the ownership proof behind your agreement exists and staff are there to receive an officer. What no package can do is produce the marketplace’s warehouse letter — only the platform issues that. Availability by state is on the state-by-state page, and city pages such as Bengaluru show what is open where the fulfilment centres cluster.

Why APOB amendments get rejected, and how to fix each one

Almost every item there is a consistency problem rather than a legal one. The VPOB and APOB guide goes deeper into the document checks, and the registration process guide covers the REG-01 stage in full.

Keeping it compliant once the stock is moving

A GSTIN in a new state is a standing commitment, not a one-time purchase. Five things follow it:

• Returns per GSTIN. GSTR-1 and GSTR-3B for each registration, monthly or quarterly under QRMP if aggregate turnover is up to ₹5 crore. Nil months still need filing; the Section 47 late fee runs at ₹50 a day (₹20 for a nil return) against turnover-based caps, with 18% a year interest on late tax under Section 50.
• Display under Rule 18. The certificate at the principal place and every additional place, the GSTIN on the name board at the entrance. It is the first thing an officer looks for.
• Invoice series per GSTIN. Rule 46 ties the supplier’s address and GSTIN to the supplying state. E-invoicing applies too once aggregate turnover has crossed ₹5 crore in any year from 2017-18.
• Keep the address alive. Renew the agreement before it lapses and file a REG-14 within 15 days of any address change. Rule 21 allows cancellation where business is not conducted from the declared place, and Section 122(1)(xi) sets a penalty of ₹10,000 or the tax evaded, whichever is higher, on a person liable to register who does not.
• Prune what you no longer use. Leaving a centre or a state means removing the APOB, and cancelling the registration if nothing is supplied from there any more.

One further point follows the multi-state footprint rather than the warehouse: where common input services such as software, audit or marketing are billed to one GSTIN but used by several, an Input Service Distributor registration is mandatory from 1 April 2025 to distribute that credit. Raise it with your accountant once the third state goes live.

What to do next

Take the platform’s fulfilment-centre list and your own sales data and write down the states where your stock will actually sit in the next twelve months. Where you already hold a GSTIN, all you need is the centre’s consent letter and a REG-14. For the rest, the work starts with an address and everything else queues behind it. Browse addresses by state, or see how sellers use them on the e-commerce page. Tell us the states, the platform and when the stock moves, and we will send back the document list, a realistic date for each GSTIN and a fixed price.
