GeekNums Glossary of Number-Filtering Terms: Master Key Concepts in One Go

I. Core Functional Terms

Number Generation: Bulk-generate mobile phone numbers based on the numbering rules of specified countries/regions. Supports various generation methods—including custom number ranges, fixed prefixes, and random number creation—covering over 220 countries and regions.

Email Generation: Generate potential email addresses based on names or nicknames for specific countries. This helps expand your lead pool; please note that generated email addresses require secondary verification to ensure validity.

Invalid Number Detection: Identify and filter out inactive, disconnected, deactivated, or non-existent phone numbers in bulk, thereby reducing marketing outreach costs.

Number Screening / Platform Registration Check: Verify whether a phone number is registered on specific social platforms (e.g., WhatsApp, Telegram, etc.) to confirm its validity on those services.

Activity Detection: Determine how recently an account has been active (e.g., within the last 3, 7, or 30 days), allowing you to target highly engaged users.

Profile Filtering: Filter users based on attributes such as age, gender, or profile picture to improve the quality of your outreach.

Multi-Dimensional Data Filtering: Refine your target list by combining various criteria—such as activity level, gender, age, profile picture, and user behavior—to enhance marketing precision.

Dual-Criteria Filtering: A filtering method that requires data to meet two or more conditions simultaneously (e.g., "active within the last 7 days" + "female"), helping to further narrow down your target audience.

List Cleaning: The process of removing duplicates and errors, as well as filtering out invalid entries from your existing dataset, resulting in a "clean" list ready for immediate marketing use.

API Integration: Integrate Geek Nums’ screening capabilities into your own systems or workflows via an Application Programming Interface (API) to enable automated, bulk processing.

II. Screening Dimension Terms

Activity-Based Filtering: Filter users based on their account activity status—for example, identifying those who have logged in or interacted with the platform within the last 3, 7, 15, or 30 days.

Gender-Based Filtering: Filter users based on the gender information provided in their public profiles, enabling targeted outreach to specific gender groups.

Age-Based Filtering: Filter users based on the age information provided in their public profiles, enabling targeted outreach to specific age demographics. Profile Picture Filter: Filters for accounts that have set a profile picture—a strong indicator that an account is authentic and active—helping to exclude low-quality, mass-registered accounts.

Behavioral Filter: Filters users based on their activity on the platform (such as interactions, transactions, or follows) to pinpoint high-value target audiences.

Email Filter: Validates and cleanses email lists in bulk, removing invalid or high-risk addresses to ensure only deliverable, valid emails remain—thereby reducing bounce rates and failed delivery attempts.

Interest-Based Targeting: Filters users according to their specific interest tags, covering vertical sectors such as e-commerce, beauty, blockchain, or personal finance.

Last Active Time: A filtering criterion that allows you to set a timeframe relative to the present; only accounts that have been active within this specified period are retained.

User Status: A filtering criterion that lets you define account status (e.g., active, flagged, or under risk control), keeping only those accounts that match your selected status.
