#Number Screening FAQ Hub: Frequently Asked Questions and Helpful Guides

When acquiring customers overseas, number screening is a basic link that the marketing team cannot avoid. When you have a batch of mobile phone numbers, you need to quickly determine which ones have Telegram activated, which ones are active WhatsApp users, and which ones are male/female users. Traditional manual verification or “test messaging” is extremely inefficient. This article integrates the multi-platform practical operation of number screening, billing model, generation and deduplication techniques, as well as the most common questions of newcomers to help you build a reusable screening workflow at the lowest cost.

What is number screening?

Number screening refers to using automated technology to perform multi-dimensional testing on a batch of mobile phone numbers: confirm whether the number is registered on a social platform (such as Telegram, WhatsApp, Line, Zalo), whether it is active (recently online), and whether the user’s gender, age, avatar and other additional information can be identified. It is completely different from ordinary number verification (which only checks whether the number format is correct).

How is number screening different from ordinary number verification?

Dimensions	Ordinary number verification	Number filtering
Detection content	Number format, operator	Social platform registration status, activity, gender, age, avatar
Application scenarios	Data cleaning	User stratification, accurate customer acquisition, AB testing
Output result	”valid” or “invalid”	activated/unactivated, active/inactive, male/female, tgid/wsid, etc.
Platform coverage	Unlimited	Each social platform is tested individually

For example: Ordinary verification can only tell you “+8613800138000 is a valid number”, while number filtering can tell you: “This number has been subscribed to Telegram, has been active in the last 7 days, the user is female, and is about 30 years old.” The latter is a qualitative leap in the value of your private message promotion in the female community.

Which industries need number screening most?

• Cross-border e-commerce & independent website promotion: It is necessary to promote new products and coupons through targeted private messages to avoid wasting on dead accounts.
• Telegram/WhatsApp community operation: Screen out active users to join the group to improve group activity and conversions.
• Overseas application new users: Accurately import users who have subscribed to a certain platform to reduce the difficulty of cold start.
• Marketing Studio/Agent Operations Team: Processing hundreds of thousands of numbers every day requires a streamlined “generate → filter → export” approach.

Core point: Number screening does not solve “whether the number can be used”, but “whether the user portrait behind the number meets your goals.”

How to filter active users and gender information on Telegram?

Telegram is one of the most commonly used private messaging channels among overseas users, and the KK-DATA platform supports multi-dimensional detection of Telegram numbers.

What detection types does Telegram filter support?

• tg activation (registration detection): Determine whether the number is registered with Telegram.
• tg active (active window can be specified): For example, detect whether there are online records in the last 7 days, 15 days, and 30 days. The larger the active window, the wider the hit, but the accuracy decreases.
• telegram gender data: Use specific algorithms to infer user gender, age, avatar, etc. Please note that gender detection is not 100% ID card-level accuracy, but the targeting capabilities on big data (such as filtering out users around 30 years old) are enough to support most marketing scenarios.
• tgid export: The user’s Telegram ID (tgid) can be exported from the filter results to facilitate subsequent followers and group messaging through API or Bot.

How to use gender and age fields to filter target users?

Suppose you want to promote a men’s skin care product, targeting men aged 25-35. You can:

1. Prepare a batch of target country numbers (for example, through global number generation + custom number segments).
2. Submit the “Telegram Screening” task and check “Gender Detection” and “Activity Detection”.
3. In the filter number results, filter out the numbers whose gender is male, whose age field is between 25-35 (age is a continuous field and the range can be set), and which have been active in the last 7 days.
4. Export the tgid of these numbers and use the Bot tool to send targeted private messages.

How to batch filter numbers on WhatsApp, Line, Zalo and other platforms?

The screen number logic of different platforms is similar, but the details are different. Brief description below:

• WhatsApp Screener: Detects activation (having a WhatsApp account), activity (recent use), and gender. Fields are subject to console export. Note that WhatsApp’s recent privacy policy adjustments will affect the availability of some fields.
• Line screen number: Line has a large number of users in Japan, Taiwan, Thailand and other regions. Supports Line activation/validity detection and Line gender recognition, which can target male or female users. Export the uid field.
• Zalo Screener: Zalo is the most mainstream social platform in Vietnam. Supports Zalo activation, activity, gender and other detection, suitable for customer acquisition scenarios in Southeast Asia. Note that Zalo numbers usually start with +84.
• iOS/iMessage: Detect whether the number activates iMessage (blue number/green number), suitable for targeted promotion of Apple device users.
• RCS: Android’s rich media messaging protocol, detects whether the number supports RCS.

You can submit multiple platform screening tasks at one time, or you can perform mixed screening across platforms. Before submitting the task, the platform will display the estimated cost to avoid overage.

How does global number generation assist in pre-testing?

Overseas marketing often requires testing the quality of numbers in different countries and different number ranges. KK-DATA provides global number generation function:

• 240+ Country/Region Numbers Randomly Generated: Enter the target country (such as Indonesia, Brazil, India) and generate a specified number of random numbers with one click.
• Global number segment generation: Batch generation based on number segment, such as US +1 number segment, or virtual operator number segment.
• Custom number segment CSV import: If you have a known number segment (such as a certain operator’s number segment), you can upload the CSV to generate it.

The generation is completely free, and the fee will be deducted based on the actual number of tests during screening. Typical workflow:

Generate a batch of target country numbers → Submit the TG/WA screening task → Export the screening results → Use them for marketing after deduplication.

How to avoid duplicate spending in data deduplication warehouse?

If there are overlaps in numbers between your multiple screening tasks, repeated testing will waste balance. KK-DATA has a built-in data deduplication warehouse that will automatically record all detected numbers. When a new task is submitted, the detected numbers will be automatically skipped and only the new number will be deducted. This means:

• If you screen some Telegram numbers first and then want to additionally check WhatsApp, the Telegram part that has already been checked will not be deducted again.
• If numbers overlap between different marketing activities, the deduplication warehouse will save you the trouble of manually deduplicating them.

What is the billing model for number screening?

KK-DATA uses per-item billing and no subscription package. Core rules:

• Deposit: USDT (TRC20) recharge, the minimum is about 50 USDT. The balance is automatically updated after payment is received.
• Deduction Timing: Deducted from the balance after the screening task is completed. The estimated cost will be displayed before the task is submitted.
• Insufficient balance: New tasks cannot be submitted and need to be recharged first.
• Different platforms have different unit prices: Telegram, WhatsApp, iMessage, RCS, Line, Zalo and other platforms have different unit prices for detection types. For specific prices, please refer to the real-time price of the console or [official website billing page] (https://kkdata.cc/billing/).

Points to save money: Estimate the cost before each screening, and deduplication warehouse can greatly reduce the cost of repeated testing. Task completion notifications can be received through Telegram Customer Service Bot.

Frequently Asked Questions about Number Filtering

**Q: Can number screening guarantee 100% accuracy? **

Answer: No. No number screening service can be 100% accurate, especially with inferred fields such as gender and age. The platform will provide a high accuracy rate (usually 90%+) within the industry average, but is not recommended for use in scenarios that require strict identity verification. It is recommended to keep a certain error tolerance when using it.

**Q: What is “tg 30-year-old data”? Is it a standalone product? **

Answer: “tg 30-year-old data” is not an independent product, but refers to the age field in the gender detection results of Telegram screens that can be used to filter users who are about 30 years old. This age field is a comprehensive estimate, not ID card level accuracy. Do not misunderstand as a standalone “age detection product”.

**Q: How many numbers can be submitted simultaneously in the number screening task? **

Answer: The maximum number for a single task is about 1 million. If the amount of data is larger, it can be submitted in batches, and the deduplication warehouse will automatically avoid repeated detection. It is recommended that a single task be controlled within 500,000 in order to get results faster.

**Q: What should I do if the balance cannot be transferred immediately after recharging? **

Answer: USDT (TRC20) deposits usually arrive within a few minutes. If the account has not been credited for a long time, please contact customer service via Two-way Contact Customer Service or customer service Telegram (@kkdata_cc) for manual processing. Note: The platform will not take the initiative to send private messages requesting transfers, so beware of counterfeit customer service scams.

**Q: Can domestic mobile phone numbers be screened? **

Answer: Yes. Global numbers can be submitted for screening as long as the number is in the correct format (international format, such as starting with +86). However, it should be noted that operators in different countries may have an impact on the effectiveness of active detection, and the actual results shall prevail.
