US data activation and active screening funnel: best practices from number generation to tiered customer acquisition

The US market has always been a key target area for overseas marketing, cross-border e-commerce and social e-commerce teams. Whether reaching users through Telegram, WhatsApp or Line, having a batch of high-quality, verifiable US number data is the first step to acquiring customers. However, many teams directly send messages and join groups after getting a batch of American numbers. As a result, a large number of numbers are unregistered and inactive, which is a waste of time and cost. This article teaches you to build a set of US data screening funnel from number generation, activation detection, activity detection to crowd stratification, control costs step by step, and leave only truly reachable active users.

What is US number data? Why is it needed to acquire overseas customers?

US number data usually refers to phone numbers starting with +1 country code (covering the United States, Canada, etc.) and can be used to register or connect to multiple social platforms (Telegram, WhatsApp, Line, Zalo, Facebook, etc.). For overseas teams, having batches of U.S. numbers does not directly lead to conversions - have the numbers been activated on the target platform? Has the user been recently active? Are the gender and age appropriate for the target population? These are the key variables that determine marketing effectiveness.

Through the two-level screening of open detection and active detection, you can:

• Change the original number list → filter out users who have registered on the platform
• Filter registered users → filter out recently active users
• Optionally, further stratify by gender and age fields

The core value of this funnel is: Every outreach is based on real, active users, greatly increasing the response rate and conversion rate.

How to generate US number data for free? Two ways and preparation checklist

Before performing the screening, you need to have a batch of numbers to be tested. KK-DATA provides two free generation methods. No prepayment is required to generate numbers. Fees will be deducted only after submitting the number screening task.

Method 1: Randomly generated by country/region

In the “Global Number Generation” module of the console, you can select the United States (+1) or Canada (+1), and the system will generate a specified number of numbers based on the real number segment and a random algorithm. Supports 240+ countries and is completely free to generate.

Method 2: Upload custom number segment CSV

If you already have certain number segments (such as a number prefix obtained from a certain channel), you can import the CSV file and the system will automatically parse and remove duplicates. This method is suitable for scenarios where some data sources already exist and need to be completed in batches.

After generating a preview of the results, just add the screening task directly. There is no charge for the generation itself, and you will only be billed on a per-item basis after you submit the test.

US data filtering funnel: first detect activation, then detect activity

In order to improve efficiency and save costs, it is recommended to proceed step by step in the order of “Activate → Active → Crowd”. At each step, only the numbers that passed the previous step are filtered out to avoid unnecessary active detection of invalid numbers.

Step one: Batch activation detection (Telegram/WhatsApp/Line, etc.)

The activation test (also called registration test) is used to verify whether the number has been registered on the target platform. For example:

• US number Telegram activation detection: Returns whether the number is registered with Telegram
• WhatsApp activation detection: Returns whether WhatsApp has been registered
• Line/Zalo activation detection: Same reason

A task can support up to about 1 million numbers. The platform will process it asynchronously and then send a notification after completion.

Step 2: Activity detection (specified time window)

Active detection is an advanced screening based on enabled detection. You can specify a time window such as “Active in the last 30 days” or “Active in the last 7 days.” The system will determine the user’s last online time based on platform data. Common types of activity detection include:

• Telegram activity detection
• WhatsApp activity detection
• Zalo activity detection and more

Supports customization of active days to flexibly match your marketing timeliness. For example, if you are doing an immediate promotion, you can only filter users who have been active in the last 3 days; if you are inviting people to join a community, you can relax it to 30 days.

Step 3: Population stratification and interpretation of gender and age fields

Based on the active list, fields such as gender and age can be optionally detected. For example, Telegram gender data will return “male/female” and age fields (such as about 30 years old, etc.). Note: These fields come from platform public information or model inference, and are not ID card-level accuracy, but are sufficient for preliminary targeting.

You can filter “American men around 30 years old” or “Women around 25-35 years old” based on the age field to further optimize the reach.

How to control the cost of US screening numbers? Billing by item and deduplication warehouse

KK-DATA adopts a no-subscription package and a pay-per-test model—you only pay for the number of successfully completed tests. Different platforms and different detection types (activated vs active vs gender) have different unit prices. For details, see the real-time price on the console.

Understand the platform price model: independent billing for different detection types

For example, the unit prices of Telegram activation detection and Telegram activity detection may be different; the unit prices of WhatsApp and Line may also be different. Before submitting the task, the console will display the estimated cost, allowing you to know the cost in advance.

Cross-task deduplication warehouse: avoid repeated deductions

If you have multiple batches of numbers that require multiple detection tasks, the Data Deduplication Warehouse function can help you deduplicate across tasks - if the same number has been detected and activated before, subsequent tasks will be automatically skipped and charges will not be deducted repeatedly. This is especially useful for doing multiple rounds of screening in a row (such as opening first and then becoming active).

US data export format and subsequent marketing actions

After the detection is completed, CSV or TXT files can be exported. Exported fields include:

• number
• Country
• Platform activation status
• Active status (last active time)
• Gender, age (if tested) -In-platform IDs such as TGID / WSID / UID

Exported data can be used for:

• Bulk private messages (via Telegram Bot or WhatsApp Business API)
• Community invitation (add directly to group)
• Import into CRM system for follow-up

Common misunderstandings and precautions in US screen size data

• Myth 1: “The age data is consistent with the ID card”. In fact, the age field comes from public information or inferences on the platform and can only be used as a reference and should not be used for detailed screening.
• Myth 2: “Activating the test will definitely replace the code.” The activation test only verifies whether the user is registered and does not guarantee that the user will be online for a long time. Need to be combined with active detection.
• Myth 3: “One mission includes all platforms.” Only one platform (such as Telegram) can be selected for each test, and multiple platforms cannot be tested at the same time (unless the tasks are submitted separately).
• Attention to fraud: KK-DATA official customer service only has Telegram account @kkdata_cc and two-way contact robot @kkdata_robot, and does not contact users through other channels. Any act of pretending to be customer service and requesting a transfer is a scam.

FAQ

**Q: What country area codes does the U.S. number data include? ** A: The main area code is +1 (United States, Canada, parts of the Caribbean), but other 240+ countries are also supported individually. The country is clearly marked when generated.

**Q: What is the difference between enabled detection and active detection? Can they be done at the same time? ** Answer: The activation test only verifies whether the number is registered with the platform; the activity detection needs to determine whether the user has been active recently based on the activation. It is recommended to activate the account first and filter out the registered numbers before submitting active tasks to avoid invalid costs.

**Q: How many numbers can be detected at most in one task? ** Answer: It is recommended that a single task should not exceed 1 million items. If it exceeds, it can be submitted in batches. Using a deduplication warehouse can avoid repeated deductions.

**Q: Are gender and age data accurate? Can you screen out “male around 30 years old”? ** A: The gender and age fields come from platform public data or model inference. They are not official demographics, but can be used as a reference for targeting. For example, approximately filter people around 30 years old through the age field.

**Q: What will happen if the balance is insufficient? Can I pay on credit? ** Answer: New tasks cannot be submitted when the balance is insufficient. Deposit currently only supports USDT (TRC20), with a minimum of about 50 USDT. Credit is not accepted.
