Why E-commerce Businesses Face Unique DPDP Challenges
E-commerce is one of the most data-intensive sectors in India. From the moment a customer visits your website to the point they receive a delivery and beyond, your platform collects, processes, and stores a staggering volume of personal data. Under the Digital Personal Data Protection (DPDP) Act, every touchpoint in this journey is now subject to compliance requirements.
India's e-commerce market is projected to exceed USD 200 billion by 2027, and with that growth comes heightened regulatory scrutiny. Whether you operate a direct-to-consumer brand, a multi-seller marketplace, or a hybrid model, the DPDP Act applies to you. The penalties for non-compliance can reach up to INR 250 crores, making it essential to get compliance right from the start.
This guide provides a complete, sector-specific breakdown of DPDP compliance for e-commerce businesses, along with a practical checklist you can implement immediately.
What Personal Data Do E-commerce Businesses Collect?
Before you can comply with DPDP, you must understand the full scope of personal data your platform handles. E-commerce businesses typically collect data across the following categories:
Account and Identity Data
- Full name, email address, phone number
- Date of birth, gender (often for personalisation)
- Profile photos and saved addresses
- Login credentials and authentication tokens
Transaction and Payment Data
- Order history and purchase amounts
- Payment method details (card numbers, UPI IDs, wallet information)
- Billing and shipping addresses
- Invoice and GST details
Behavioural and Analytics Data
- Browsing history, search queries, product views
- Wishlist and cart contents
- Click patterns, session duration, device fingerprints
- Location data from IP addresses or GPS
Communication Data
- Customer support chat transcripts
- Email correspondence and complaint records
- Reviews, ratings, and feedback
Each of these data categories has specific consent and processing requirements under the DPDP Act. A thorough DPDP assessment can help you map these data flows and identify compliance gaps.
Consent Requirements for E-commerce Transactions
The DPDP Act mandates that consent must be free, specific, informed, unconditional, and unambiguous. For e-commerce businesses, this has several practical implications.
Transactional Consent
When a customer places an order, they provide data necessary to fulfil a contract. The DPDP Act recognises legitimate uses as a valid basis for processing data that is strictly necessary for order fulfilment. This means you do not need separate consent for processing the shipping address to deliver a product, but you do need consent for anything beyond what is necessary for the transaction.
Marketing Consent
Sending promotional emails, push notifications, or SMS marketing requires explicit, opt-in consent. Under DPDP, you cannot bundle marketing consent with transactional consent. The customer must have a clear, separate choice to opt in to marketing communications. Pre-checked boxes are not valid consent.
Analytics and Profiling Consent
If you use customer data for behavioural profiling, personalised recommendations, or targeted advertising, you need separate consent for these activities. The purpose must be clearly explained in language the customer can understand. Blanket consent clauses buried in lengthy terms of service will not satisfy DPDP requirements.
Third-Party Sharing Consent
If you share customer data with advertising networks, analytics providers, or affiliate partners, you must disclose this clearly and obtain consent. The data principal has the right to know exactly who receives their data and for what purpose.
Implementing a robust consent management platform is essential for handling these varied consent requirements across your e-commerce platform.
Payment Data Handling Under DPDP
Payment data deserves special attention because it sits at the intersection of multiple regulatory frameworks. In addition to DPDP, e-commerce businesses must comply with RBI guidelines on payment data storage and PCI DSS requirements.
Key Requirements
- Data minimisation: Only collect payment data that is strictly necessary for transaction processing
- Storage limitation: Do not retain full card numbers or CVV codes beyond the transaction
- Tokenisation: Use RBI-mandated card tokenisation for recurring payments
- Encryption: All payment data must be encrypted in transit and at rest
- Access controls: Restrict payment data access to authorised personnel only
If you use payment gateways like Razorpay, PayU, or CCAvenue, ensure your data processing agreements with these providers include DPDP-compliant clauses regarding data handling, breach notification, and data deletion.
Marketing Emails and Customer Communication
E-commerce businesses rely heavily on email marketing, push notifications, and SMS campaigns to drive sales. Under DPDP, each of these channels requires careful compliance planning.
Email Marketing Compliance
- Obtain explicit opt-in consent before adding customers to marketing lists
- Provide a clear, one-click unsubscribe mechanism in every email
- Maintain records of when and how consent was obtained
- Respect consent withdrawal within a reasonable timeframe (ideally within 24-48 hours)
- Do not use dark patterns to make unsubscription difficult
Push Notifications and SMS
- Push notification permissions obtained through the browser or app are a form of consent, but they should be supplemented with clear disclosure about the types of notifications the customer will receive
- SMS marketing must comply with both DPDP and TRAI regulations
- Transactional SMS (order confirmations, delivery updates) are generally permissible, but promotional SMS requires separate consent
Abandoned Cart and Retargeting
Abandoned cart emails and retargeting campaigns are common e-commerce practices. Under DPDP, you need consent for tracking browsing behaviour and sending follow-up communications based on that behaviour. Make sure your consent mechanism covers these use cases explicitly.
Customer Profiling and Personalisation
Personalisation drives conversion in e-commerce, but it also creates DPDP compliance obligations. Customer profiling involves processing personal data to evaluate certain aspects of an individual, such as preferences, interests, behaviour, and purchasing patterns.
DPDP Requirements for Profiling
- Clearly disclose that you engage in profiling activities
- Explain what data is used and how profiles are created
- Obtain specific consent for profiling purposes
- Allow customers to opt out of profiling without losing access to basic services
- Do not make decisions with significant effects solely based on automated profiling without human oversight
If you use machine learning algorithms for product recommendations, dynamic pricing, or customer segmentation, these activities fall under profiling and require compliance measures.
Children's Data in Online Shopping
The DPDP Act sets the age of a child at below 18 years and imposes strict requirements on processing children's data. E-commerce businesses must implement age verification mechanisms and obtain verifiable parental consent before processing data of users under 18.
Practical Implications
- Age gates: Implement age verification at account creation
- Parental consent: If you knowingly serve children (e.g., kids' clothing, toys, educational products), you must obtain verifiable consent from a parent or guardian
- No behavioural tracking: The DPDP Act prohibits behavioural tracking and targeted advertising directed at children
- Data minimisation: Collect only the minimum data necessary when processing children's data
If your e-commerce platform sells products targeted at children, or if a significant portion of your customer base is under 18, this area requires dedicated compliance attention.
Vendor and Marketplace Seller Obligations
If you operate a marketplace model, you have obligations both as a Data Fiduciary for the platform and in relation to the sellers on your platform who may also process customer data.
Platform Responsibilities
- Establish clear data processing agreements with all marketplace sellers
- Define what customer data sellers can access and for what purposes
- Ensure sellers cannot export or misuse customer data
- Implement technical controls to restrict seller access to only necessary data
- Monitor seller compliance with data protection requirements
Logistics and Delivery Partners
- Delivery partners receive customer names, addresses, and phone numbers for order fulfilment
- Ensure delivery partners delete this data after order completion
- Include data protection clauses in logistics agreements
- Monitor for unauthorised use of customer data by delivery personnel
Managing these vendor relationships effectively requires a structured third-party risk management programme.
