Complete guide to US ws number export: CSV/TXT field selection, naming specifications and downstream marketing applications

Most of the overseas customer acquisition teams have encountered this kind of confusion: they spent time collecting a large number of American mobile phone numbers, but after investing in marketing tools, they found that a large number of numbers were not registered for WhatsApp, or were registered but were inactive for a long time and could not send messages at all. The key value of US ws number (i.e. US WhatsApp number) is not “large quantity”, but “confirmed and accessible”. Exporting these verified numbers in batches and organizing them in CSV or TXT format is a necessary prerequisite for subsequent private message promotion and community recruitment.

This article will teach you how to efficiently manage exported US WhatsApp numbers from three dimensions: field selection, file naming specifications, and downstream application scenarios. At the same time, practical operation suggestions will be given based on the functions of the KK-DATA platform.

What is a US WS number? Why do you need to export in batches?

Simply put, US ws number is a US mobile phone number that has been registered with WhatsApp. For overseas marketers, these numbers mean that they can be directly used for WhatsApp private messages, group recruitment, and customer contact. However, the original mobile phone number pool may contain a large number of unregistered, canceled or long-term inactive numbers. Directly importing the tool will cause a waste of resources and the risk of account suspension.

The core value of batch export is:

• Screen out the truly reachable numbers: After activation and activity detection, only valid and communicable numbers will be retained.
• Support hierarchical operation: Group numbers according to gender, active period and other fields, and send different marketing content respectively.
• Connection automation process: Directly import CSV/TXT into bulk sending software or CRM to achieve batch contact.

The KK-DATA platform allows users to complete the entire process of “number generation (optional) → detection → export” in the same task, and finally obtain clean and structured US WS number data.

What core fields should be selected when exporting US WS numbers?

Before exporting, be sure to think clearly about “what scenarios these numbers will be used for.” Selecting fields based on their purpose of use can significantly reduce the difficulty of subsequent data cleaning.

Required fields: activation status and activity

• Activation Status: Confirm whether the US mobile phone number is registered with WhatsApp. Unactivated numbers are filtered directly.
• Active ID: For example, “Online in the last 7 days”, “Online in the last 30 days”. This is a basic condition for marketing, and only active users may see the message.

These two fields are the bottom line for all export tasks, and it is recommended to check them for each export. KK-DATA will return a clear Boolean value or timestamp during detection to facilitate subsequent screening.

Optional fields: gender and avatar (for user portraits)

• Gender: When you need to target male or female audiences (such as beauty products, men’s health categories), you can check gender detection. KK-DATA infers gender based on WhatsApp public information with high accuracy.
• Avatar: Accounts with avatars usually have stronger real-person attributes and are suitable for use in high-trust scenarios (such as finance, education); numbers without avatars can be downgraded first.
• Age (part range): KK-DATA gender detection includes an age field, which can help interpret groups around 30 and 40 years old, and is suitable for pan-age targeting. Note that this is not the exact age at the ID card level.

Extended fields: wsid, country code and timestamp

• wsid: The unique ID of the WhatsApp account, which can be used for subsequent deduplication or API docking (such as matching with user data in your own CRM).
• Country Code: Although US ws numbers are usually +1, if Canadian and other country numbers are mixed, export the country code field to facilitate separation.
• Detection timestamp: Record the last detection time of the number, which is used to analyze the number’s active period and determine whether it needs to be detected again.

Export Suggestions: Do not export all fields unless necessary, otherwise the CSV file will be too large; streamline according to the scenario, for example, if you are only doing mass promotion, just check the three columns of “Active”, “Active” and “Gender”.

How to set the CSV/TXT export naming convention to avoid data confusion?

Many teams pile up the files after exporting, and cannot find the corresponding batch when they need to use them another day. Having a fixed set of naming conventions can greatly reduce confusion.

Naming rule examples and common misunderstandings

Recommended format: [国家]_[平台]_[日期]_[检测条件]_[字段缩写].csv

Example:

• US_WS_20250401_active_male.csv (US WhatsApp, exported April 1, 2025, active + male)
• US_WS_2025-04_all_gender.csv (all genders)
• 美国ws号码_2025-04_开通+活跃+性别.csv (Chinese is also available, but it is recommended to use English to avoid encoding problems in different systems)

Common Misunderstandings:

• Use special symbols such as spaces, slashes, question marks (some tools do not recognize paths).
• Do not indicate the detection type (for example, “output.csv”, you won’t know whether it is enabled or active in two days).
• The date format is not standard (it is recommended to use YYYYMMDD or YYYY-MM-DD).

How to manage unified management when exporting multiple batches

1. With task ID: Each sieve number task in KK-DATA has a unique ID. It is recommended to add “_task_123456” at the end of the file name.
2. Create archive folder: Group by month or project, such as ./美国ws号码/2025-04/.
3. Use deduplication warehouse: KK-DATA has a built-in data deduplication warehouse, which will record whether each number has been detected. Repeat submission of the same number will not result in repeated deductions. You can also select “Export only unexported numbers” when exporting to avoid duplicate files.

What can I do after exporting the US WS number? Downstream usage recommendations

Once you get the cleaned US WhatsApp number, you can immediately connect it to marketing tools. Here are three common uses.

导入自动化营销工具

Most bulk sending software (such as WhatsApp Business API integration tools, third-party bulk senders) support CSV or TXT import. Need to pay attention to:

• International format: The mobile phone number column must contain the country code, such as +1234567890, and the ”+” cannot be missed.
• No blank lines: Each line of the TXT file has a number, and no blank lines are left at the end, otherwise the tool may report an error.
• Field Mapping: When importing CSV, the tool usually requires you to select the corresponding columns (such as mobile phone number, name, gender). Maintaining consistent English column names in the CSV header row in advance can save you the trouble of later mapping.

Combine with other platforms for cross-validation

If you want to know whether the same user is also on Telegram, Line or Zalo, you can take advantage of KK-DATA’s cross-platform filtering capabilities. Upload the US WS number to another detection task and select “TG activated/active” and other types to determine whether the user is using other social platforms at the same time. This kind of “cross-platform user portrait” is suitable for precision marketing, such as pushing in-depth content to users who use both WhatsApp and Telegram.

Build a private domain traffic pool

Import US WS numbers that have been actively tested into corporate WeChat or personal WhatsApp accounts in batches, and convert users to private domains through automatic welcome messages, community invitations, etc. Note that the number of messages sent in a single day must be controlled within the platform limit (for example, a WhatsApp personal account cannot send more than a few hundred messages per day).

Frequently Asked Questions and Pitfall Guidelines for Exporting US WS Numbers

Problem	Cause	Solution
CSV garbled characters (displayed as ?? in Chinese)	Encoding problem	Select UTF-8 with BOM encoding when exporting; open with Notepad++ or VS Code
Fields are missing (one column is missing)	Export configuration is not checked	Submit export again, be sure to check the number of columns in the preview interface
The same number appears repeatedly	Multiple batches of tasks are not deduplicated	Use KK-DATA to deduplicate the warehouse, or check “Only not exported” when exporting
The file is too large to open	Export millions of rows at one time	Export in batches, each batch ≤ 500,000 rows; or use professional data processing tools (such as Python/Pandas)
The number cannot be imported into the mass sending tool	The format does not match (missing + or containing spaces)	Use a text editor to batch replace: delete the spaces and add ”+” before the country code

Why is it recommended to use KK-DATA to export US ws numbers?

From a practical perspective, KK-DATA has solved several key pain points:

1. Rich and flexible fields: Not only provides activation, activity, gender, but also supports extended fields such as wsid, detection timestamp; users can freely combine according to the scenario.
2. “Generate→Detect→Export” full link: If you don’t have enough numbers on hand, you can directly use the “Global Number Generation” module to randomly generate US number segments (240+ countries) for free, and you will be deducted on a per-item basis when testing.
3. Deduplicate warehouse to avoid duplication of work: As long as they are under the same KK-DATA account, all detection records will be shared and deduplicated, and the same number will not be repeatedly tested or deducted.
4. Real-time estimated fees: You can see the estimated deduction amount before submitting the task. If the balance is insufficient, you cannot submit it to avoid overspending.
5. Multi-format export: One-click switching between CSV and TXT, and supports batch downloading.

In addition, you will be notified through Telegram when the task is completed, so you can get the data as soon as possible. For Team cooperation scenarios, it is not a problem to export millions of US WS numbers at one time.

FAQ

Q: What file formats are supported for US ws number export?

Answer: Supports two common formats: CSV and TXT. CSV contains the column headers of each field, which is suitable for subsequent data processing; TXT only contains one line of numbers, which is suitable for direct import into mass sending tools. The specific export can be selected in the console.

Q: What fields are included in the exported CSV file?

Answer: Depending on the selected detection type (such as activation, activity, gender, etc.), it will at least include mobile phone number, activation status, and activity ID; if gender detection is selected, it will also include metadata such as gender, age (within a certain range), as well as wsid, detection time, and other metadata. The complete field list is subject to the real-time export configuration of the console.

Question: How to avoid exporting the same US ws number repeatedly?

Answer: It is recommended to use the “data deduplication warehouse” function of KK-DATA. The system will automatically record the numbers that have been tested, and will automatically skip the tested numbers when submitting new tasks to avoid repeated deductions and repeated exports. You can also check “Export only numbers that have not been exported” when exporting.

Question: How to correctly import the exported TXT file into the marketing tool?

Answer: Make sure the number is in international format (such as +1xxxxxxxxxx), with one number per line and no blank lines. Some tools require numbers without the ”+” sign or to remove the country code. Please pay attention to the field settings when exporting or use a text editor to perform batch replacement.

Question: Is the activity detection of US WS numbers accurate?

Answer: KK-DATA makes judgments based on WhatsApp’s public online status and server feedback. The active window (such as online in the last 7 days/30 days) can be customized. The accuracy is limited by the platform algorithm and user privacy settings. It is recommended to use activity as a reference indicator rather than an absolute standard, and pay attention to the statistics after the task is completed.
