Can You Deny Giving Phone Number To Shops?

In everyday shopping, many stores ask customers for their phone numbers for marketing, delivery, or loyalty programs. However, consumers often wonder whether they are legally required to share this personal information or if they can refuse without any negative consequences.

Can You Deny Giving Your Phone Number To Shops?

No Legal Obligation to Provide Phone Number

Generally, consumers are not legally obligated to provide their phone numbers to shops unless required by law or for specific services like online deliveries.

For in-store purchases or walk-in transactions, customers can refuse to share their phone number.

Purpose and Consent

Shops must clearly explain why they need your phone number—whether for contactless delivery, billing, or marketing.

Personal data like phone numbers should be collected only with the customer’s explicit consent.

Consent must be voluntary and informed; customers should not feel pressured or coerced.

Data Protection and Privacy Rights

Under data protection laws such as India’s Digital Personal Data Protection Act (DPDP) 2023 or GDPR in Europe, phone numbers are personal data and must be handled with care.

Shops must use the phone number only for the stated purpose and cannot share it without your permission.

Consumers have the right to ask how their data will be used, stored, and protected.

Exceptions

Some services, like online food delivery or courier services, may require a phone number to coordinate delivery and verify identity.

In such cases, providing the number may be essential to complete the transaction.

Refusing Phone Number and Potential Consequences

You can refuse to provide your phone number in most cases.

However, refusal might limit your access to certain services, offers, or delivery options.

Retailers should provide alternative options whenever possible.

Right to Withdraw Consent

If you provide your phone number, you have the right to withdraw consent for marketing or promotional communications at any time.

You can request deletion or anonymization of your data as per applicable data laws.

Example

A customer visits a clothing store and is asked to provide their phone number for a loyalty program. The customer politely declines, stating they do not wish to share personal contact details. The store allows the customer to make the purchase without any issue. Later, the customer orders a product online from the same store and provides their phone number to coordinate delivery, understanding that this is necessary for service completion.
