For data linked to a mobile phone number, companies can primarily obtain data they collect directly through their own services. This includes:
First-party data: User registration details (name, email), purchase history, website Browse behavior (if logged in), app usage, customer service interactions, and loyalty program data. All this is tied to the mobile number provided by the user.
Third-party data (with consent): Some data brokers might offer aggregated, anonymized demographic or interest data linked to phone number segments, but this is less granular and requires strict compliance.
Operator data (for telcos): Mobile network operators themselves have access to call, SMS, and data usage patterns of their subscribers' numbers. They can use this for internal analytics or provide anonymized insights to partners under strict agreements and user consent.
Data Linked via WeChat UID
For data bound to a WeChat UID, businesses primarily rely on:
Official WeChat Public Accounts or Mini Programs: If your business operates an official WeChat Public Account or Mini Program, you can collect user data (e.g., profile info like nickname, gender, city if provided, and interaction history within your account/mini program) when users interact with your services. This often involves specific API calls after users grant permission.
WeChat Business API: For advanced use cases, the WeChat Business API allows approved enterprises to integrate their CRM systems with WeChat, enabling more sophisticated data collection and personalized communication with users uruguay phone number list who have subscribed to their services on WeChat.
User Consent and Privacy: It's crucial to understand that WeChat (and similar platforms) strictly control access to user data. Any data collection must adhere to WeChat's platform policies and, critically, gain explicit user consent. Unauthorized scraping or collection of WeChat UIDs and associated personal data is strictly prohibited and can lead to account suspension and legal action.
Ethical and Legal Compliance
Regardless of the source, ethical and legal compliance is paramount. Any data collection must be transparent, obtain explicit user consent, and adhere to relevant data protection laws (e.g., GDPR, CCPA, and local regulations in Bangladesh like the Digital Security Act). Unauthorized data acquisition is not only illegal but also severely damages trust and brand reputation.
