Tracking warranty for online purchases
Brand-level vs merchant-level warranty
For 95% of branded electronics, appliances and accessories sold on Indian marketplaces, the warranty is the brand's. Apple deals with iPhone claims; Samsung deals with Samsung; Sony deals with Sony. The merchant's role ends when delivery is confirmed.
The two routine exceptions:
- Merchant-operated extended warranty plans — Croma Care, Reliance ResQ, Amazon Protection Plans, Flipkart Complete Mobile Protection. These are explicit add-ons sold at checkout; the merchant is the warrantor, with their own claim portal and SLA.
- Marketplace own-brand — products under the marketplace's own private label. Here the marketplace is the brand, so the warranty channel is the marketplace's help-center.
The four anchors of a claimable warranty
1. Proof of purchase
The merchant's tax invoice or e-invoice. PDF in your email is acceptable to nearly every brand; print is not required.
2. Serial number / IMEI
Stamped on the device, the box, and (for phones) inside Settings → About. Brands trace warranty by serial; the invoice ties the serial to your purchase date.
3. Registration window
Some brands require pre-registration via their app or website within 15–30 days of purchase. Skipping it can default the warranty start date to the manufacture date — which can shave weeks off the term.
4. Channel
Brand-authorised service centre, brand support number, or brand app. Third-party repair shops void warranty for most brands; opening the device yourself voids nearly all of them.
Why warranty hygiene falls apart
A 24-month warranty asks you to keep three artefacts findable for two years across forwarded emails, three Gmail filters, and a phone you may have changed: the invoice PDF, the serial number, and the registration confirmation if you bothered. The failure mode is rarely the brand refusing the claim — it is the customer not being able to reproduce the proof on day 540.
An inbox-driven warranty registry solves the third problem by treating your email as the source of truth: the invoice is already there, the serial is in the order confirmation, the registration confirmation is in your inbox if it happened.

Frequently asked
Who honours the warranty — the merchant or the brand?
Almost always the brand. The merchant is the seller and provides the invoice that anchors the warranty start date, but actual repairs, replacements and claim approvals run through the brand's authorised service centre or call channel. There are exceptions for marketplace own-brand and merchant-extended warranties (Croma Care, Reliance ResQ, Amazon protection plans), where the merchant operates the warranty itself.
What proof is needed to claim warranty?
Two core anchors: (1) proof of purchase — original invoice or e-invoice from the merchant — and (2) the product serial / IMEI number. Some brands also require pre-registration via their app or web portal within a stated window (often 15–30 days from purchase), failing which the warranty start date may default to the manufacture date instead of the purchase date.
What if I lost the invoice?
It is still claimable. The Consumer Affairs Ministry has publicly clarified that consumers can claim warranty benefits even without an invoice, and most reputable brands accept the e-invoice from the merchant's order history, the serial-number-linked product registration, or a credit-card / UPI statement showing the purchase. See our dedicated guide on claiming warranty without an invoice.
Does the warranty period start at purchase or delivery?
Standard practice is delivery date for most brands; some appliance brands start from the installation date. Always check the brand's warranty card — the date it asks you to record is the canonical start date.
