This data collection allows businesses to track what items recent mobile phone number data customers buy, when, and how often.
2. Linking Shopping History to Phone Numbers
Phone numbers serve as a convenient unique identifier for businesses to link various data points, including shopping history. Here’s how:
Customer Profiles: Phone numbers help create unified customer profiles across channels, consolidating online and offline purchases.
Personalized Marketing: Businesses use these profiles to send targeted offers, coupons, and recommendations via SMS or calls.
Fraud Prevention: Linking shopping activity to phone numbers can help detect suspicious behavior.
Because phone numbers are often stable identifiers tied directly to the individual, they are effective in associating shopping data.
