Retailers commonly request a phone number to locate or create a loyalty account. Connecting purchases to one number lets the store apply member discounts, record reward points, find digital receipts, and review previous purchases when processing returns.
The number may also be used for delivery updates, warranty records, fraud prevention, customer-service follow-ups, or promotional texts. More importantly, it can help the retailer build a profile of someone’s shopping habits. Loyalty programs may connect contact details with products purchased, visit frequency, spending patterns, and preferred locations. The FTC notes that loyalty-card use can give businesses information about customers’ habits and purchases.
That does not mean shoppers must automatically provide it. For an ordinary in-store purchase, you can usually politely say, “No, thank you,” and continue paying. Ask whether the number is required for the transaction or merely for rewards and marketing. Certain services, such as deliveries, financing, special orders, or warranties, may genuinely require contact information.
Before joining a loyalty program, check how the retailer says it collects, uses, and shares personal information. The FTC recommends reviewing a company’s privacy policy to understand its data practices.
The customer in the image had a reasonable privacy concern, but yelling at the cashier was unnecessary. Cashiers are usually following the checkout prompts created by the company. Declining calmly—or asking why the number is needed—is the better response.
