US ws number batch screening tutorial: Use KK-DATA to quickly verify US WhatsApp numbers

If you are engaged in overseas marketing, cross-border e-commerce or community operations, there is a high probability that you will come into contact with the “US ws number” - that is, the US WhatsApp number (US WA number). Whether it is sending promotional messages to US users, attracting new members to the group, or verifying whether the obtained numbers are valid, batch screening of US WS numbers is a basic and high-frequency task. Manual inspection one by one is time-consuming, labor-intensive, and error-prone. This article will use a complete tutorial to teach you how to use the KK-DATA platform to quickly complete multi-dimensional screening of US WhatsApp numbers such as activation, activity, gender, etc., and export the available data.

What is a US WS number? Why do you need batch screening?

US ws number, literally translated as US WhatsApp number (US WA number / US WS activated number). It refers to a US mobile phone number (usually starting with +1) that is registered with WhatsApp. In the overseas customer acquisition scenario, you may have a list of US mobile phone numbers, but many of them may be:

• Not registered with WhatsApp;
• Registered but inactive for a long time (such as not online for more than 30 days);
• Registered but not in the target gender/age group.

The significance of batch screening is to spend your limited marketing budget on real, active, and relevant users. Manually send verification messages one by one? Thousands of messages a day is the limit. Use automated screening tools to submit hundreds of thousands of numbers at a time, and get results within a few minutes to tens of minutes, improving efficiency by a hundred times.

Upload number list and create screening task

KK-DATA provides two ways to include US ws numbers into screening tasks.

Method 1: Directly upload existing number files

If you already have a list of US mobile phone numbers (for example, generated from public number segments, historical data, purchase lists, etc.), you can upload it directly.

• File Format: Supports CSV or TXT, one number per line.
• Number Format: It is recommended to bring the international area code. US numbers start with +1, such as +14151234567. It may be recognized without +, but with the area code it is more accurate.
• Operating steps:
  1. Navigate to the left side of the console and select “Screen Task” → “New Task”.
  2. Select the “Upload Number” method to upload the file.
  3. Select the test type: What you need is WhatsApp Screener, and further select “Activate Test” (required), “Active Test”, “Gender Test”, etc. It is recommended to at least check “Activate” to exclude unregistered numbers.
  4. Submit the task. The system will first calculate the estimated cost (number of items displayed × unit price), and then formally submit it after confirmation.

Method 2: Use global number generation module

If you don’t have a ready-made number on hand, you can use KK-DATA’s “Global Number Generation” function to generate a US number for free** and then import the screen number.

• Enter the “Number Generation” module, select the country “United States”, or directly enter the US number segment (such as +1415, +1212, etc.). -Set the generated number, and the system will randomly generate a list of numbers that conform to the number segment rules.
• After generation, click “Import Screen Numbers” to directly convert this batch of numbers into screen number tasks. No fee will be deducted for the generation itself, only the actual number of detected items will be deducted.

View filter results and field interpretation

After the task is completed (usually within a few minutes to tens of minutes, depending on the task volume), you can click the task in the “Screen Task” list to view the results.

Detailed explanation of result fields

Taking WhatsApp filter number as an example, the result table usually contains the following fields (specifically subject to console export):

Field	Description
Number	Original mobile phone number
Activation	Yes means the number has been registered for WhatsApp; No means it has not been registered
Active	Active / Inactive, you can specify the active window (such as the last 7 days, 30 days)
Gender	Algorithmically inferred gender (Male/Female/Unknown) for crowd targeting
Age	Inferred age range (such as 25-34), can be used to filter people around 30 years old
Avatar	Do you have a WhatsApp avatar (partially displayed)
Last online time	Some numbers can return timestamp

Note: Gender and age fields are algorithm inferred, suitable for trend analysis and coarse-grained targeting, and are not guaranteed to be 100% accurate (for example, ID card level accuracy cannot be achieved). If you need accurate gender, it is recommended to cross-verify with indicators such as message response rate.

Export data and format selection

• Click the “Export” button and select the export format: CSV (recommended, can be opened in Excel or Google Sheets) or TXT.
• You can export only the “opened” and “active” numbers, or you can export all fields.
• The exported files can be used directly in mass mailing tools, CRM systems or subsequent marketing processes.

How to improve the screening efficiency and accuracy of US ws numbers?

Combined with best practices, the following tips can help you get better results for less:

1. Use high-quality number segments: The first few digits of U.S. numbers (such as 415, 212, 310, etc.) often represent large cities, and the registration rate and activity in these areas are usually higher. Priority is given to generating numbers from large city number segments.
2. Set a reasonable active window: If your marketing activity requires users to be online recently, set the active detection window to “nearly 7 days” or “nearly 30 days”. If you only need to be registered, you can uncheck active detection to save costs.
3. Submit large tasks in batches: The maximum number of single tasks is about 1 million. If the number exceeds this number, it is recommended to split it into multiple tasks or contact customer service (https://t.me/kkdata_robot）沟通批量处理方案。
4. Use data to deduplicate warehouse: Tasks in different batches may have duplicate numbers. Before submitting a new task, deduplicate other data sources (such as historical filtered numbers) to avoid wasting balances.
5. Combined detection type: For example, do “activation detection” first, and then do “gender detection” or “activity detection” for the activated number. Compared with checking everything at once, segmented execution can flexibly control costs.
