Global Number Screening FAQ: High-Frequency Questions & Best Practices Guide for Overseas Customer Acquisition

Cross-border marketing, overseas social media operations, private traffic generation… no matter which track your business focuses on, one unavoidable step is number screening. From Telegram group member addition to WhatsApp bulk messaging, from iMessage promotion to empty number cleaning, global number screening has become the infrastructure for overseas teams. However, faced with various detection types, billing models, and platform rules, many operators will have a series of questions: What is the difference between activity detection and account detection? What is the principle of gender identification? How to avoid duplicate detection and waste budget?

This article, in the form of a Global Number Screening FAQ, compiles high-frequency questions and best practices from basic concepts to hands-on implementation. Whether you are a newcomer just learning about number screening or an experienced operator looking to optimize your existing process, you will find actionable answers here.

What is Global Number Screening? – Basic Concepts & Applicable Scenarios

Global number screening refers to using technical means to batch verify the registration status, activity level, or even gender information of a set of phone numbers on specific social platforms (such as Telegram, WhatsApp, iMessage, RCS), thereby filtering out truly reachable user numbers. Its core value lies in:

Improving reach rate: Remove empty numbers and numbers not registered on the platform, and only send messages to valid users.
Reducing cost: Avoid wasting sending costs on invalid numbers (SMS, API calls, or even labor costs).
Refined operations: Stratify based on dimensions such as activity and gender, and match different content to different users.

Typical application scenarios include:

Scenario	Screening Target	Common Detection Types
TG group member addition	Get Telegram active users	Account detection + Activity detection
WhatsApp bulk messaging	Filter out unregistered or long-term offline numbers	Valid number detection + wsid export
iMessage marketing	Confirm Apple device numbers	iMessage account detection
RCS/carrier cleaning	Remove empty numbers, disconnected numbers	Empty/carrier detection
Cross-border CRM cleaning	Unified deduplication and add platform attributes	Multi-platform screening + data deduplication

What are the Common Detection Types in Global Number Screening?

A professional screening platform usually offers multiple detection dimensions, each solving a different problem:

Account detection (registration detection): Verify whether a number is registered on the platform. For example, Telegram account detection, WhatsApp valid number detection. This is the most basic filtering layer.
Activity detection: Determine whether the number has shown usage behavior within a recent time window (e.g., 7 days / 15 days / 30 days). Active users have a higher marketing response rate.
Gender identification: Use AI to identify gender through Telegram or WhatsApp profile photos/nicknames, helping operators target promotion by gender.
Platform ID export: Obtain the corresponding Telegram ID (tgid) or WhatsApp ID (wsid) for the number, making it easy to call the API directly to send messages, avoiding changes in phone numbers.
Empty/carrier detection: Confirm whether the number actually exists, whether it is disconnected or ported, used for cleaning before SMS marketing.
Cross-platform screening: Simultaneously detect the status of one number on multiple platforms, e.g., check both Telegram and WhatsApp, and output a comprehensive report.

Account Detection vs Activity Detection – Differences & How to Choose

Dimension	Account Detection	Activity Detection
What it detects	Whether registered on platform	Whether used recently
Typical use	Clean unregistered numbers, build available pool	Screen high-frequency users, improve response rate
Time cost	Low (feedback in seconds)	High (requires observing behavior)
Recommended scenario	First pass large-scale screening	Secondary screening with strict quality requirements

Practical advice: First run account detection to get a “valid pool”; then run activity detection to extract an “active pool”. This two-step process can save 40%–60% of waste on invalid delivery costs.

What are Gender Identification and Platform ID Export (tgid/wsid) Used For?

Gender identification: If your marketing content has a gender preference (e.g., women’s products, men’s games), you can filter numbers by gender to avoid causing aversion in mass sends. Note: Accuracy depends on profile photo/nickname data and cannot reach 100%.
tgid/wsid export: The platform ID is a unique identifier within the platform, more stable than a phone number (the ID remains unchanged even if the user changes their number). After export, it can be used directly for Telegram Bot or WhatsApp Business API pushes, saving the step of number conversion.

How to Connect Number Generation with Screening? – The Complete Process from Generation to Screening

Many teams get stuck at the first step: “Where do the numbers come from?” Professional screening platforms usually offer global number generation functions, allowing you to freely create a number pool and then seamlessly proceed to screening.

Common Methods of Global Number Generation (Random, Prefix, CSV Import)

Generation Method	Description	Applicable Scenarios
Random generation	Randomly generate numbers based on country code and prefix rules	Small-scale testing, exploring without a target market
Prefix generation	Enter a specific prefix (e.g., US 213 area code) and generate consecutive or random numbers under that prefix	Precision acquisition targeting a specific city/carrier
CSV import	Upload your existing number list (e.g., purchased data, existing customer data) to the platform	Cleaning historical data, deduplication

Generation is completely free; only when you enter screening (detection) do you get charged per record. Therefore, you can generate a large number of numbers without worry, then narrow down the scope.

How to Avoid Duplicate Detection? The Role of a Data Deduplication Repository

Money-saving Tip

Data deduplication repository is a built-in database in the platform that automatically records all numbers you have historically detected along with their results (platform, activity status, etc.). When you submit duplicate numbers in a new task, the system automatically skips them and does not charge again.

Best practice: Always first run new numbers through the deduplication repository to clean them, then submit the screening task. If one person uploads the same batch repeatedly, it’s just wasting balance. The deduplication repository can also recognize duplicates across tasks (e.g., you tested numbers for Congo Kinshasa yesterday, today you test numbers for Nigeria; duplicate numbers are automatically skipped).

How to Choose a Screening Platform? – Evaluation Criteria & Pitfalls to Avoid

The quality of screening tools on the market varies greatly. When choosing, we suggest evaluating from 5 dimensions:

Data accuracy: Does the detection result reflect the real state? You can test with a small number of known numbers.
Billing transparency: Are there hidden fees? Does it show an estimated cost before submitting a task? A pay-per-record, no subscription package model is more flexible.
Platform coverage: Does it support all the social platforms you need (Telegram, WhatsApp, iMessage, RCS, etc.) and countries/regions?
Task capacity: How many numbers can be processed in a single task? For million-level projects, a small upper limit would mean frequent splitting.
After-sales support: Is there Chinese-language customer service? Having an official Telegram channel or customer service facilitates communication.

Anti-fraud Reminder

Use official channels: The platform’s official site (https://kkdata.cc/) and customer service Telegram (@kkdata_cc). Do not trust unofficial agents, and beware of fake customer service attempting to defraud you of numbers or funds.

Also, don’t be fooled by claims of “99.9% accuracy.” The detection process is affected by network status, platform API conditions, etc. Normal accuracy ranges between 95%–98%. Always rely on actual task results.

Billing Model & Cost Control for Global Number Screening

Mainstream screening platforms (e.g., KK-DATA) adopt a balance top-up + pay per record model, with no monthly or annual fees. Advantages:

Pay for what you use: Small teams can start with low thresholds, while large teams can scale elastically.
No waste: No charge unless detection is performed; you only pay after detection based on actual number of records and type.
Low-cost trial: Top up a small amount of USDT (minimum ~50 USDT) first, evaluate the results after running the first batch, then replenish.

Billing Notice

Specific unit prices are based on real-time prices in the console. Estimated fees are shown before submission, and charges are made only after task completion. See the billing page.

Cost control tips:

Use the data deduplication repository to avoid duplicate detection.
Run account detection first (lower unit price), then run activity detection (potentially higher price) only on passed numbers.
Estimate costs when submitting tasks to ensure sufficient balance, preventing task failure due to insufficient funds.
When bulk submitting, do not submit too many useless numbers at once (e.g., directly detecting a full set of randomly generated numbers). First generate by prefix, run a small test to determine the valid number rate, then proceed with the full quantity.

Common Issues & Solutions During Screening Task Execution

Issue	Cause	Solution
Task shows “Processing” for a long time	Large number of records or platform detection service queuing	Wait; you will receive a Telegram notification upon completion (need to bind in advance).
Task fails due to insufficient balance	Did not confirm available balance before submission	Check balance in console before submission, or top up enough to cover estimated fees.
Detection results differ greatly from expectations	Low prefix quality or platform API fluctuation	Test prefix quality on a small scale first; if anomalies persist, contact customer service.
Export format incompatible with subsequent tools	Did not customize export fields	Supports CSV/TXT with customizable fields: you can select number, platform status, gender, tgid, etc.
Cannot receive task completion notification	Did not bind Telegram notification settings	In the console “Notification Settings”, fill in your Telegram user ID (tgid) and confirm the bot has been added.

Also, it is recommended to periodically clean up historical tasks to avoid the console being overloaded with too much data.

Future Trends & Compliance Suggestions for Global Number Screening

As overseas social media platforms tighten restrictions on bulk operations (e.g., Telegram limiting mass messaging, WhatsApp enforcing stricter account bans), compliance in number screening becomes increasingly important:

Prioritize active number detection: Send messages only to users who have been active recently, reducing harassment complaints.
Respect user privacy: Do not use screening results for illegal purposes, such as spam advertising or fraud.
Choose a reliable platform: Use screening tools with clear privacy policies to avoid data leaks.

In terms of technical trends, features like cross-platform ID correlation, AI-assisted gender identification, and real-time streaming detection will become more common. The core philosophy remains: Use the minimum cost to obtain the most precise outreach opportunity.

Frequently Asked Questions

Q: Which platforms can be detected by global number screening?

A: Currently, mainstream platforms include Telegram, WhatsApp, iMessage, RCS, etc. The specific detection types (account/valid/active/gender) supported by different platforms can be viewed in the console. For example, KK-DATA supports Telegram account, valid, active (7/15/30 days), gender identification, tgid export; WhatsApp valid number detection, wsid export; iMessage and RCS account detection, etc.

Q: What is the maximum number of numbers I can submit at once? How long does screening take?

A: Each task supports up to about 1 million numbers. Processing time depends on the total number of records and the status of the platform detection service, usually ranging from a few minutes to several hours. After the task is completed, you can receive a notification via Telegram without having to monitor the screen constantly.

Q: Can I get a refund for my top-up balance? What happens to unused balance?

A: Top-up balances are non-refundable. It is recommended to top up a small amount based on estimated fees, and add more after it is used up, to avoid idle funds. If you no longer use the service in the future, you can contact customer service to discuss the balance handling plan (policies may vary by platform).

Q: Can I use generated numbers directly? Do I need to screen them first?

A: Generated numbers are unverified, either random or based on prefixes. It is recommended to screen them first (e.g., account detection, activity detection) before using them for marketing. Otherwise, a large number of invalid numbers will reduce reach rates and waste costs. Generation is free, only screening costs money, so screening before using is the most economical approach.

Q: What export formats are supported for screening results?

A: Common formats such as CSV, TXT are supported. Export fields can be customized (e.g., number, platform, activity status, gender, etc.), making it convenient for subsequent import into CRM or further processing. Some platforms also support direct push of results to cloud storage or via API callbacks.
