Five Strategies for Batch Screening of US Phone Numbers: A Full-process Analysis from Data Cleansing to Precision Marketing

Strategy 1: Compliance First – Anchoring the Legal Boundaries of US Phone Number Screening

• Core Compliance Principle: Batch screening of US phone numbers must take US communication regulations as the bottom line. Violations may face fines of up to $16,000 per occurrence, so compliance review must be carried out throughout the screening process.
• Core Regulatory Requirements: Strictly abide by the Telephone Consumer Protection Act (TCPA) and the Anti-Robocall Abuse Criminal Enforcement and Deterrence Act. Core requirements include obtaining the user's prior written consent before sending marketing information and avoiding making marketing calls outside working hours (8:00 AM to 9:00 PM).
• Key Compliance Actions: Numbers registered in the US National Do Not Call Registry must be 100% excluded, which is a rigid requirement for batch screening of US phone numbers.
• Compliance Empowerment by ITG Tool: The ITG Global Screening Tool can synchronously connect to the database of the US Federal Trade Commission (FTC), automatically eliminate "Do Not Call" numbers, and identify the number's operator and user consent status to ensure the compliance of screening results.
• Practical Effect Case: A cross-border e-commerce enterprise achieved a 100% elimination rate of high-risk compliance numbers through this strategy, successfully avoiding legal disputes caused by illegal marketing.
  
  

Strategy 2: Source Purification – Building a Multi-dimensional Preliminary Screening System for US Phone Numbers

• Core Goal of Preliminary Screening: Improve the quality of the initial number pool and reduce resource waste in subsequent screening, which is the basis for improving the efficiency of batch screening of US phone numbers.
• Pain Points in US Phone Number Screening: The number of US phone number resources is huge (over 330 million in-use numbers), and number segments are updated frequently. Single-dimensional screening is prone to missing invalid data.
• Core of Preliminary Screening System: Establish a multi-dimensional mechanism of "source verification + basic attributes" to control the data quality of batch screening of US phone numbers from the source.
• Priority to Compliant Sources: Prioritize resources obtained through compliant channels, such as US local business directory platforms (e.g., golocal247.com), industry exhibition registration information, and official website form submission data, to reduce the proportion of invalid numbers.
• Preliminary Screening Function of ITG Tool: Supports batch screening of US phone numbers by geographical regions (core consumer markets such as California and New York), number types (mobile/fixed/toll-free numbers), and affiliated operators.
• Data Support Advantage: Connect to the XConnect RealNumber DNO database (containing 6 billion North American number information) to quickly identify invalid number segments, reducing the inefficiency rate of preliminary screening by more than 40%.
• Case Result: A cross-border logistics enterprise increased the validity rate of its initial number pool from 35% to 72% through this strategy, significantly reducing subsequent screening costs.
  
  

Strategy 3: Intelligent Cleansing – ITG Global Screening Enables Real-time Verification of Number Status

• Positioning of Intelligent Cleansing: As the core link of batch screening of US phone numbers, its main task is to accurately identify the number status and eliminate invalid resources such as empty numbers and suspended numbers.
• Challenges of US Number Characteristics: US phone numbers have strong mobility, with the proportion of empty numbers and suspended numbers remaining at 30%-50% all year round. Traditional manual verification cannot meet the needs of large-scale batch screening of US phone numbers.
• Necessity of Tool Dependence: The technical empowerment of the ITG Global Screening Tool is the key to realizing efficient cleansing in the batch screening of US phone numbers.
• Real-time Data Connection Capability: Directly connect to the interfaces of the four major US operators (Verizon, AT&T, T-Mobile, Sprint) to achieve millisecond-level status response and accurately identify four statuses including active numbers and empty numbers.
• Core Technical Advantages: First, high concurrency processing (tens of millions of data per hour) to support rapid screening of hundreds of millions of US phone numbers; second, daily data updates to solve the problem of status changes caused by number reallocation.
• Practical Application Value: A fintech enterprise used it for batch screening of US phone numbers, achieving an empty number identification accuracy of 99.2% and saving more than $120,000 in invalid SMS costs per month.
  
  

Strategy 4: Value Stratification – Accurate Positioning of US Phone Numbers Based on User Portraits

• Goal of Value Stratification: Convert valid numbers after cleansing into precise marketing leads, maximize the value of batch screening of US phone numbers, and focus on high-net-worth customers.
• Core Logic of Stratification: Combine US consumer behavior data with number attributes to build multi-dimensional user portraits and distinguish the value levels of numbers.
• Stratification Dimensions of ITG Tool: Integrate multiple types of data to achieve three-dimensional scoring – geographical dimension (core consumer cities, high-income zip codes), behavioral dimension (inquiry about high-priced products, event participation), and risk dimension (excluding frequently complained numbers, etc.).
• Number Classification Results: Divide into three categories: "high-intent core customers", "potential cultivation customers", and "low-value excluded customers". The conversion rate of high-intent customers is 6-8 times higher than that of ordinary numbers.
• Case Reference: Shenzhen Tianmei Overseas Warehouse positioned US cross-border e-commerce seller numbers through this strategy, increasing the conversion rate of logistics consultations by 45%.
  
  

Strategy 5: Closed-loop Linkage – Seamless Connection Between Screening Results and Marketing Systems

• Core Significance of Closed-loop: Convert the results of batch screening of US phone numbers into actual marketing actions, and improve conversion effects through the linkage of "screening - reach - follow-up - optimization".
• Key Implementation Actions: Achieve seamless connection between screening results and enterprise CRM and SCRM systems to ensure the rapid implementation of screening value.
• System Connection Capability: The ITG Global Screening Tool supports API connection with mainstream CRM systems such as Salesforce. After batch screening of US phone numbers, it automatically synchronizes tagged numbers to the marketing system.
• Realization of Personalized Reach: Can trigger customized processes, such as pushing local warehouse network information to high-intent e-commerce sellers in California, and updating interaction records in real-time to adjust strategies.
• Dual Value Manifestation: After a cross-border electronics enterprise applied this strategy, the marketing conversion cycle was shortened from 15 days to 7 days, and the conversion rate increased by 32%; the "billing by valid numbers" model of ITG reduces the tool cost to only 1/5 of the traditional method.
