GST Additional Place of Business for Warehouses and Dark Stores: Practical Case Study for Indian Users
Warehouses, godowns, dark stores and fulfilment centres are classified as Additional Places of Business (APOB) under GST. Adding them correctly to the GST.tration ensures ITC flows correctly, consignment notes (e-way bills) are valid and no supply is deemed to occur without a proper invoice. This guide covers the amendment procedure, document requirements and a worked case study for quick commerce operators.
Why APOB Registration Matters for Warehouses
If a business stores goods at a location not registered under GST, any movement of goods from that location could be treated as a supply without an invoice — attracting penalties and ITC denial to the recipient. Every godown, warehouse or dark store from which goods are dispatched must be an APOB under the business's GST registration.
Adding APOB: Amendment Procedure
To add a warehouse or dark store as APOB:
- Log into GST portal → Services → Registration → Amendment of Registration (Core Fields) — addition of an Additional Place of Business is classified as a core field on the GST portal, not a non-core field
- Navigate to 'Additional Places of Business' tab
- Add new address with state (must be same state as PPOB for APOB; other states need a separate GSTIN)
- Upload address proof: rent agreement + utility bill of warehouse; or ownership document if own property
- Because it is a core field, the amendment is routed to the jurisdictional tax officer for review and is not automatically approved — the officer can approve, seek clarification, or reject within the prescribed timeline (typically 15 working days; deemed approved only if the officer takes no action within that window)
- Once approved, the updated GSTIN certificate is issued digitally — download and use for e-way bill generation

Case Study: Zeph Grocery — Mumbai Dark Store Expansion
Zeph Grocery has its registered office in Andheri, Mumbai. It operates 5 dark stores across Mumbai (Bandra, Malad, Thane, Navi Mumbai, Pune). Pune is a separate district but still within Maharashtra.
All 5 Maharashtra stores are added as APOBs to the single MH GSTIN by filing a core-field amendment via the portal. Since this is a core field, the jurisdictional officer has up to 15 working days to review and approve (or the amendment is deemed approved if no action is taken within that window) — Zeph should plan dispatch timelines around this, rather than assuming next-day approval. E-way bills can be generated correctly from each store address once the amendment is approved and reflected on the registration certificate.
