Complete strategy for data detection: How to scientifically conduct activation detection and valid number screening (the first step to reduce the number of empty numbers)

In overseas marketing, data detection is the starting point to improve reach efficiency and reduce the empty call rate. Whether it is Telegram community promotion, WhatsApp private message group sending, or Line/Zalo customer acquisition in Southeast Asia, whether the batch verification number is activated on the target platform and whether it is authentic and effective directly determines the marketing cost and conversion effect.

This article takes you through the complete process of “activation detection→valid number screening→activity judgment” from concept to practical operation, and attaches a practical checklist and frequently asked questions. We hope to help your team reduce ineffective contacts and spend budget on real users.

What is data detection? The difference between activation detection and valid number screening

Data Validation (Data Validation) here specifically refers to batch verification of the status of mobile phone numbers on a specific platform, including: whether the number is registered on the platform, whether it is active, whether it can receive messages, and the accompanying group attributes (gender, age, etc.). It helps the marketing team eliminate invalid numbers before formal contact and improves the success rate of follow-up actions.

Activation detection: Verify whether the number is registered with the target platform

Open detection is the most basic and most cost-effective type of data detection. For example, if you have a batch of mobile phone numbers and want to know which of them have been registered with Telegram or WhatsApp, you only need to submit these numbers, and the system will return the “activated” status of each number (activated/not activated/invalid). This is the first step in screening “potential reach targets.”

• Applicable scenarios: Batch verification whether the number is activated on Telegram/WhatsApp/Line and other platforms. After confirmation, it can be used to join groups, private messages or advertising.
• Technical Principle: Simulate queries through the platform public protocol or API, which does not involve the leakage of user privacy data and only determines the registration status.

Valid number screening: further determine the availability and activity of the number

The concept of valid number is broader than “activation”. Even if a number is registered with Telegram, it may not be able to receive messages if the user does not log in for a long time, uninstalls the app, or changes devices. Therefore, on the basis of opening the detection, many teams will conduct valid number screening (also known as activity detection):

• Activity Detection: Determine whether the number has been online within the latest period of time (such as 7 days, 30 days). The reach rate of active users is significantly higher than that of silent users.
• Gender/Age Identification: The detection results of some platforms (such as Telegram, Line) can also return gender, age and other group fields to help marketers accurately target.

Summary: The activation test answers “Can the door be found?”, and the valid number screening answers “Is there anyone behind the door?”

Why is the overseas marketing team inseparable from data detection?

Suppose you blindly send 1,000 marketing messages. If 800 of them are empty or unactivated, it means:

• Waste of cost: Each SMS/SNS API call will incur a fee, and empty accounts will directly burn money.
• Account Risk: Failure to send a large number of messages may cause your sending account to be risk controlled or even banned by the platform.
• Reputation Damage: If the number belongs to someone else (not the target user), frequent invalid calls will trigger complaints and damage the brand image.

As a pre-step, data detection can screen out at least 60% to 80% of invalid numbers in advance (according to industry experience), increasing the reach rate of the remaining numbers to over 90%. This investment usually pays for itself after the first marketing campaign.

How to check the activation of Telegram/WhatsApp and other platforms? (Practical process)

The following takes the KK-DATA platform as an example to demonstrate the standard steps from preparing numbers to outputting test results. The process of other screening tools is similar and you can refer to this logic.

Step 1: Prepare the list of numbers to be detected (source and format)

• Source: It can be the customer phone number of your own CRM, industry data package, or a new number generated by a global number generation tool.
• Format: It is recommended to use international format (e.g. +8613800138000), one number per line, and save as CSV or TXT file.
• Duplication removal: Be sure to check for duplicate numbers before submitting. KK-DATA has a built-in “data deduplication warehouse” that automatically filters detected numbers to avoid repeated deductions. See the documentation for details https://docs.kkdata.cc/

Step 2: Select detection items on the screening platform and submit the task

1. Log in to the console https://app.kkdata.cc/ and enter the “Create Task” page.
2. Select the target platform (e.g. Telegram, WhatsApp, Line, Zalo, etc.).
3. Check the detection type:
   • Activation detection: Returns “Activated/Not activated/Invalid”.
   • Valid Detection (Activity): Returns “Last Online Time” or “Active/Silent” tags.
   • Gender Identification: After checking, the system will output the gender and age fields (note: age is an estimated range, not an exact value).
4. Upload the number file or paste the number list, and the system will display the estimated fee (billing per item, subject to the real-time price on the console).
5. Click Submit and wait for the task to be completed. After the task is completed, you can use the Telegram robot (https://t.me/kkdata_robot）接收通知。

Step 3: Interpret the test results—distinguish between open/unopened/invalid

• Activated: The number has been registered on the target platform and can be reached.
• Not activated: The number itself is valid (can connect to text messages/calls), but has not yet registered for the platform. It is suitable to guide registration through invitation link or SMS.
• Invalid: The number cannot be connected (empty number, outage, format error). This part of the number should be discarded directly.

Valid number detection and activity filtering: How to judge “good” numbers?

A “good” number is not simply “activated”, but one that can truly reach the target users. For overseas marketing, it is recommended to superimpose the following detection dimensions.

Filter by active period: lock recent online users

• Active Window Selection: For example, filter numbers that are “online within the past 7 days”, or “online within the past 30 days”. Different windows should be selected for different marketing scenarios:
  • Promotions/limited time offers → It is recommended to be active within 7 days.
  • Community invitation/content push → Just be online within 30 days.
• The last online time or active status of each number will be displayed in the detection results. Select the number whose “active” is yes for subsequent operations.

Use gender and age data to accurately target target groups

• Telegram (tg) gender detection: Some detection tasks can output gender and age fields. For example, “tg 30-year-old data” means that the age field in the test results can be used to filter out people who are approximately 30 years old. Please note that the age data is an algorithmic estimate and cannot be accurate to the ID card level.
• Line Gender Detection: Supports the screening of “male” users, which is very practical in vertical fields such as beauty and games in Southeast Asia.
• Operation suggestion: Check the “Gender Identification” option when creating the task, and use Excel to filter the required gender/age range after exporting the results.

Common misunderstandings and precautions in data detection

1. Ignoring duplication removal leads to repeated deductions: This is the most common mistake made by novices. Duplicate numbers should be cleared in the “Data Deduplication Warehouse” before each submission. KK-DATA’s deduplication warehouse is cross-task, and one deduplication is valid for life.
2. The detection unit price of mixed use of different platforms: The detection unit prices of Telegram, WhatsApp, iMessage and other platforms are different. Be sure to confirm the selected platform and detection type before submitting the task to avoid misoperation.
3. Misjudgment detection result field: For example, “Activated” only means registration, but does not mean that the message can be received. It is best to add activity detection before marketing, otherwise a large number of messages may enter the dead account. In addition, age data are estimates and should not be used for precise age marketing.
4. Unable to submit tasks due to insufficient balance: KK-DATA deducts fees per item, and new tasks cannot be submitted when the balance is insufficient. It is recommended to recharge in advance. The recharge method is USDT (TRC20), with a minimum of about 50 USDT.

How to evaluate the service quality and cost of data detection?

• Billing by item, no subscription package: You only pay for the numbers you actually detect, and there is no monthly or annual fee binding. It is suitable for small and medium-sized teams to flexibly control their budgets.
• Real-time price transparency: Log in to the console to view the unit price of each platform and each detection type. The estimated cost will be displayed before submitting the task, so you have an idea.
• Supports multiple detection dimensions: activation, activity, gender, age, etc., which can be combined as needed. When combined testing, the fees are superimposed based on the number of entries, but it is usually more cost-effective than separate testing (because multiple fields can be obtained in one task).
• Data Security: The platform does not store your number file (it will be deleted or anonymized after the task is completed) to ensure privacy compliance.

Data detection practical operation list (Checklist)

The following are the standard operating steps for each data detection task, and it is recommended that the team copy and execute them:

1. Prepare Number: Export the number from a CRM, data provider or KK-DATA global number generation tool in the international format (+ country code + number).
2. Deduplication: Log in to the console → Data deduplication warehouse → Upload the number list and clear the detected numbers.
3. Select Platform: Choose Telegram / WhatsApp / Line / Zalo / iMessage / RCS, etc. according to your marketing goals.
4. Select detection type: At least check “Enable detection”; if you need precise targeting, add “Activity detection” and “Gender recognition”.
5. Submit task: Check the estimated expenses and confirm that the balance is sufficient before submitting.
6. Waiting for completion: Usually a few minutes to a few hours (depending on the number of numbers), notifications can be received through the Telegram bot https://t.me/kkdata_robot.
7. View results: View the detection results of each number (activated/not activated/invalid/active, etc.) on the “Task Details” page.
8. Export results: Select CSV or TXT format to download, which can be used for subsequent import into marketing tools.
9. Return deduplication: Add the number detected this time to the deduplication warehouse to avoid repeated detection next time.

FAQ

**Q: What is “activation detection”? What is the difference from “valid number” detection? ** Answer: Activation detection refers to verifying whether a mobile phone number has registered an account (i.e. “activation”) on a certain platform (such as Telegram, WhatsApp). Valid number detection usually includes a wider range of judgments, such as whether the number actually exists, whether it can receive text messages, and even whether it has been online recently (activity). Activating detection is the first step in screening valid numbers.

**Q: If the test results show that the number is “activated”, does it mean that it can definitely reach the user? ** Answer: Not necessarily. It only means that the number has been registered on the target platform. If the user does not log in for a long time, uninstalls the app, or changes devices, they may not receive the message. It is recommended to add “activity” detection (such as online in the past 7 days/30 days) in marketing scenarios to increase the reach rate.

**Q: What is the charging standard for data detection? ** Answer: Billing is per item, and each number will be deducted based on the selected platform and detection type. No subscription package, use after recharging. For specific unit prices, please log in to the console https://app.kkdata.cc/ to view real-time prices.

**Q: Can the test results be exported? What formats are supported? ** Answer: Yes. Most screening platforms support exporting to CSV, TXT and other formats. The fields include number, test results (activated/unactivated), activity, gender, age, etc., to facilitate the import of subsequent marketing tools.

**Q: If I test the same number in different batches, will there be repeated deductions? ** Answer: If duplication processing is not performed, repeated deductions will be made. It is recommended to use the platform’s built-in “data deduplication warehouse” function to automatically filter detected numbers before submitting tasks to avoid wasting balances.
