American WS number standard workflow: number generation → activation detection → active/gender screening → export

For overseas marketing and cross-border e-commerce teams, US WS number (i.e. US WhatsApp account) is a high-value resource to reach North American users. American numbers have natural platform trust among overseas users, and the opening rate and reply rate of sent messages are often higher than virtual numbers or niche area numbers. However, blindly purchasing or using unverified number lists will lead to a waste of marketing resources, account risk control, and even bans. The core value of US WS Numbers lies in “screening” - accurately finding US WA Numbers that are registered for WhatsApp, active, and match the target gender from a large number of potential numbers.

This article will take the KK-DATA platform as an example to fully demonstrate a standard US WS number screening process: from number generation, activation detection, to activity and gender screening, and finally exporting available data. This workflow is suitable for scenarios such as B2B customer development, independent website traffic, and community recruitment.

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

US WS Number is essentially a US mobile number that is registered with WhatsApp. It can be a real US entity number (such as AT&T, T-Mobile number segment), or it can be a number that conforms to the number segment rules. When acquiring overseas customers, using US WS number has the following advantages:

• High Trust: North American users are accustomed to using WhatsApp and are more receptive to messages from local US numbers.
• Wide coverage: The United States is the top three markets in the world for WhatsApp users, covering a large number of potential customers.
• Marketing Compliance: Compared with bulk sending, one-on-one contact through a verified US number is more in line with the platform usage policy.

However, the original number pool usually contains a large number of invalid, unregistered, and long-term inactive numbers. Sending messages directly is not only a waste of money, but may also trigger WhatsApp’s anti-spam detection. Therefore, screening is a key prerequisite for the entire customer acquisition process - you need to first identify which ones are real US WS opening numbers and which ones are active users, and then conduct targeted marketing to the target audience (such as men, people around 30 years old).

Panoramic overview of US WS number screening workflow

The complete US WS Number screening can be summarized into the following five steps. The KK-DATA platform supports one-stop completion of all links:

1. Number generation: Obtain the original number pool (randomly generate or import custom number segments).
2. Activation detection: Verify whether the number has been registered with WhatsApp (i.e. US WA number).
3. Activity + Gender Screening: On the basis of activation, fields such as recent active time, gender and age are detected.
4. Data deduplication: Automatically skip detected numbers across tasks to avoid repeated deductions.
5. Export: Select fields as needed (such as activation status, male, active within 30 days) and download the CSV/TXT file.

Below we break down the specific operation methods of each step one by one.

Step 1: How to generate a high-quality US WA number?

KK-DATA provides two ways to obtain the initial number list, neither of which consumes balance (generation is free).

Use global number generator

Enter the KK-DATA console and select the “Number Generation” module:

1. Select Country/Region: Find “United States” in the list.
2. Set quantity: Enter the number of numbers to be generated. A single task supports up to about 1 million numbers.
3. Enable random generation: The system will automatically generate random numbers based on mainstream US number ranges (such as +1-212, +1-310, etc.).
4. Click to generate: You can get the number list in a few seconds, support online preview or direct download.

Import custom number segments

If you already have some number segments (such as a certain area code or a specific operator’s number segment), you can import them in batches through CSV files:

• Format requirements: Each line in the CSV file contains a phone number (including international area code, such as +14155551234). No header is needed, just plain text.
• Applicable scenarios: Number segments obtained from other channels, re-screening of old customer lists, etc.
• Operation method: Select “Import CSV” on the generation page → Upload the file → The system will automatically parse and add the number pool.

Step 2: What is US WS activation detection? How to do it?

Activation detection is the core part of the screening workflow - it verifies whether the number is actually registered with WhatsApp. Only numbers that pass the activation test are truly counted as US WS activation numbers, and subsequent activity and gender tests are meaningful.

Submit detection task

Complete the following operations on the KK-DATA console:

1. Create Task: Select “Screen Task” → “WhatsApp Activation Detection”.
2. Select Number List: Select the generated US number from the “Number Generation” module, or paste the number list directly.
3. Estimated fee: The system will display the estimated fee amount (based on the real-time price of the current platform) before submission. Submit after confirmation.
4. Task waiting and notification: The task queue is processed in the order of submission, and notifications can be received through Telegram after completion (requires binding in advance).

Interpret test results

After the task is completed, the exported data contains the following key fields:

• phone_number: Number (including international area code)
• whatsapp_opened: activation status (true means registered, false means not registered)
• Other meta-information (such as detection timestamp)

Recommendation: Prioritize the screening of numbers whatsapp_opened = true as a candidate pool for the next step of analysis. Note: Even if the status is true, it does not mean that the number has been active recently and you need to continue filtering.

Step 3: How to further filter activity and gender?

It’s not enough to enable detection alone - you need to accurately reach the target users who are actively using WhatsApp** and target them based on gender and age.

What is activity detection?

KK-DATA supports setting active window (such as online within the last 7 days, 15 days, and 30 days). The system will detect the usage behavior of the number within the specified window (such as sending and receiving messages, checking status, etc.). Activity detection results will return:

• activity_level: High/Medium/Low or specific days
• last_seen: Last online time (such as 2024-08-15)

Usage Suggestions: For B2B marketing, it is recommended to use the “active within 30 days” window, taking into account quantity and quality; for events or promotions, the “active within 7 days” window can lock in high-potential users who have been online recently.

Gender identification and age field interpretation

KK-DATA’s WhatsApp gender detection is based on a public data model and returns the following fields:

• gender: male, female, unknown
• age_range: Age range (e.g. 25-30, 30-35)
• profile_url, avatar_url and other auxiliary fields

Note: Gender and age detection are not 100% accurate, and do not treat it as ID-level accurate information. The correct usage is as a population targeting reference - for example, “filter out users who are male and whose age field shows about 30 years old”, for precise advertising or sending customized content.

Suggested step-by-step operation:

1. First complete the “WhatsApp activation” test → export the activated number.
2. Use the activated number as the input of the new task → Submit the “Activity Detection” and “Gender Detection” merge tasks.
3. Check the conditions such as 开通=true + 活跃 + 性别=男性 + 年龄≈30 when exporting.

Step 4: Data export and cross-task deduplication

Export format and fields

Click “Export” on the task details page and select the format:

• CSV: suitable for Excel/database secondary processing, including all fields.
• TXT: Pure number list, suitable for direct import into marketing tools or sending API.

It is recommended to customize the export fields: for example, only export “phone number, activation status, active days, gender, age”. Avoid exporting irrelevant columns and reduce data volume.

How to set up deduplication?

Data deduplication warehouse is a practical function of KK-DATA, which can significantly save balance:

• How to enable it: When creating a new task, check “Enable deduplication warehouse”.
• How ​​it works: The system will record the number that has been tested in the warehouse; if the newly submitted number already exists in the warehouse (and the test type is the same), it will be automatically skipped and no repeated deductions will be made.
• Cross-task and cross-platform deduplication: Whether it is the same “activation detection” or a subsequent “active detection”, as long as the number is repeated, the system can identify it.

Best practices and precautions for US WS number screening

1. Number source quality: Do not use randomly guessed number segments. It is best to obtain numbers covering mainstream number ranges through a global number generator, or import a verified customer list. Low-quality number segments will lead to a large number of “unregistered” results and a waste of testing fees.
2. Avoid frequent submission of very small tasks: If there are only a few dozen tasks at a time, although the total cost is low, it will occupy queue resources. It is recommended to accumulate more than 1000 items before submitting.
3. Recharge Balance: Be sure to have sufficient balance before submitting large batch tasks (USDT TRC20 anonymous recharge is supported, with a minimum of about 50 USDT). Insufficient balance cannot submit new tasks.
4. Pay attention to real-time prices: The unit prices of different detection types (activated, active, gender) are different and may be adjusted with the market. Check the real-time price of the console before submitting and plan your budget appropriately.
5. Combined with scenario selection window: Use “active within 30 days” for new recruits or group invitations; use “active within 7 days” for promotional activities; gender and age screening can be superimposed on precise B2B customer development.

FAQ

Question: Does the US WS number support batch generation? How many can be generated at most at one time?

Answer: Support batch generation. Through the KK-DATA global number generator, select the United States as your nationality, set the number (up to about 1 million for a single task), and the generation is completely free. It also supports importing custom number segments through CSV to supplement the existing number pool.

Question: How to ensure that the US WS number is not repeatedly detected to avoid wasting balance?

Answer: Use the data deduplication warehouse function of KK-DATA. When creating a new task, check “Enable deduplication warehouse”, and the system will automatically compare historical detection records, skip detection for already detected numbers, and only deduct the fees for new numbers or undetected numbers. Supports cross-task and cross-platform (such as Telegram and WhatsApp) deduplication.

Question: Are the gender recognition results accurate? Can it be used for precision marketing?

Answer: Gender recognition is based on public data models, the accuracy is high but not 100%, and may return “unknown” fields. The age field can be used as a crowd reference (for example, the filter field displays users about 30 years old), which is suitable for batch targeted marketing. It is not recommended for ID card or passport level authentication and should be used as a secondary filter, not the only criterion.

Question: After the screening is completed, how to export the US WS number results?

Answer: After the task is completed, click the “Export” button on the “Task Details” page of the console. Two formats are supported: CSV (including all or optional fields) and TXT (pure number list). You can only check the required fields, such as “Activation status = true + Gender = Male + Active days ≥ 7 days” to reduce redundant data.

Question: What is the difference between US WS number activation detection and activity detection? Can we do it together?

Answer: The detection dimensions of the two are different:

• Activation detection: Only verify whether the number is registered with WhatsApp (returns true/false).
• Activity Detection: Further determine its recent usage behavior (such as whether it is online within 7 days/30 days), and return the active window or number of days.

The task can be submitted in two steps: first activate the detection → export the activated number → then submit the active detection. You can also submit the “mixed detection” task at once, and the system will combine the billing. See the real-time price on the console for specific fees and options.
