A complete guide to acquiring and screening active WS data in the United States: activation, activity, gender, deduplication and export (topic navigation)

In overseas marketing, US WS active data refers to mobile phone numbers that have been tested and confirmed to be registered WhatsApp users in the United States and have had online behavior in the recent past (such as within 7 days or 30 days). This type of data is the “ammunition arsenal” for the BS5 industry, cross-border e-commerce operators, and community promotion teams - only by using real and active numbers to reach users can the private message opening rate and conversion rate reach ideal levels. This topic will focus on the four major links of “Generation → Screen Number → Deduplication → Export” to give you a complete breakdown of how to efficiently build a high-quality US WS active number library through the KK-DATA platform. If you have not come into contact with the screening tool, it is recommended to visit the [Control Panel] (https://app.kkdata.cc/) to learn about the basic functions. Each subsequent chapter is equipped with independent special article links, which can directly access the practical details in one step.

What is “US WS Active Data”? Why is it needed for overseas marketing?

“US WS active data” is not an ordinary phone number list, but a collection of numbers that have been verified in multiple dimensions. By using this kind of data, overseas marketers can significantly reduce the proportion of invalid contacts and avoid being judged as bulk spammers by WhatsApp. The following explains its core value from two perspectives.

The fundamental difference between active data and ordinary number lists

Common number lists may come from random generation, old database exports, or third-party purchases, where a large number of numbers are down, logged out, or never registered with WhatsApp. The US WS active data has been filtered as follows:

• Activation Test (Registration Test): Confirm whether the number has registered a WhatsApp account.
• Activity Detection: Get the last online time or activity level of a number. Only numbers that meet the “activity window” you set (such as the last 24 hours, 7 days, 30 days) will be marked as active.
• Gender and additional fields: Some platforms (such as KK-DATA) can also provide gender identification (inferred based on public data) to help targeted marketing.

Therefore, the “gold content” of active data is much higher than the original number list, which directly affects the ROI of marketing activities.

Which business scenarios rely most on high-quality active data

• Customer Acquisition through Private Message: To send product introduction or promotional information to US WS users, the number needs to be real and active, otherwise the account will be easily blocked when the sending volume reaches the threshold.
• Community Recruitment: Invite active users to join Telegram/WhatsApp groups. Active numbers are more likely to be successfully invited and are willing to interact.
• Testing and Research: To conduct questionnaires or A/B tests for specific groups of people (such as men, a certain age group), an active and gendered number group is required.

How to generate US WhatsApp numbers in batches? (Getting started with the global number generation module)

Before you start screening numbers, you need a “seed” batch of numbers. KK-DATA’s global number generation module allows you to generate potential numbers in batches by country and number segment. The generation process is completely free and only provides raw materials for subsequent screening.

The steps are as follows:

1. Log in to the [Application Console] (https://app.kkdata.cc/) and enter the “Number Generation” module.
2. Select the country as “USA”. KK-DATA supports 240+ countries/regions, and the US number range includes common 318, 347, 917, 646, etc.
3. Set the number of generated items (it is recommended that a single batch should not exceed 1 million items, and it can be generated multiple times in the future).
4. Click “Generate” to obtain the number list in CSV/TXT format.
5. Save the generated results for subsequent screening tasks.

How to activate WhatsApp activation detection and activity screening in the United States?

After you have the seed numbers, the core work is to conduct activation detection and activity screening on them. The KK-DATA platform encapsulates this process as a “number screening task”. You only need to upload the number list and select the detection type.

Task submission process

1. Select the “WhatsApp Screener” task type in the console.
2. Upload the generated CSV/TXT file of US numbers (one number per line).
3. Check the detection options:
   • Activation Test (Registration Test): Verify whether the number has been registered with WhatsApp.
   • Activity Detection: Select an activity window (e.g. “Last 7 days”). The system returns each number’s last online time or activity level.
   • (Optional) Gender recognition: Get the gender field as well.
4. Check the estimated fee (the console will display the estimated deduction amount for this test, which is billed on a per-item basis. The actual deduction will be based on the completed fee).
5. Confirm submission. After the task is completed, the system will notify you through Telegram (requires binding in advance), or you can view the results in the task list.

Differences and selection suggestions between activation detection and activity detection

Detection type	Detection content	Applicable scenarios
Activation test	Whether the number is registered with WhatsApp	Initial screening: Confirm that the number is available, suitable for teams with limited budget and only need basic verification
Activity detection	The last online time or activity level after number registration	Accurate reach: only send to recently active numbers to reduce invalid messages

Suggestion: If you have enough budget, do activation + activity detection at the same time. If you only want to save costs, you can activate it first, and then perform activity detection on a subset of the activated numbers. KK-DATA supports batch submission and flexible control.

How to set the “active window” to match different marketing rhythms?

• Instant marketing (such as discounts within 24 hours): Select the “last 24 hours” active window to ensure that the number can be reached immediately.
• Regular promotion (such as weekly report): Select “last 7 days” or “last 14 days”.
• Long-term activation (such as dormant user recall): can be relaxed to “last 30 days” or “last 60 days”.

The shorter the active window, the smaller the number of filtered numbers, but the higher the activity. Please weigh this against the timeliness of your marketing campaign.

Gender identification of US WS active numbers: Can it target male or female users?

In addition to liveliness, many scenes require directional sex. KK-DATA’s WhatsApp gender recognition function can infer the gender of the number (male, female, unknown), and may have additional fields such as age, race, etc. (subject to the fields exported by the console).

Accuracy of gender data and description of applicable scenarios

• Accuracy: Inferred based on nickname, avatar, Bio and other public data, not 100% accurate, usually between 70%-90%. It is not suitable for ID card-level accurate scenarios, but it is enough to support mass marketing.
• Applicable scenarios:
  • Male user targeting (such as games, car accessories, men’s skin care products)
  • Targeting female users (such as beauty, mother and baby, fashion)
  • Filtering for specific age groups (for example, people “about 30 years old” can be filtered through the age field)

Double screening strategy combining activity and gender

Typical operation process:

1. Generate a US number → activate the detection to get the available number → perform the activity detection to get the active number → use gender recognition to get the gender field.
2. After exporting the results, filter the numbers with “Active=Yes” and “Gender=Male” in Excel to use them to reach private messages for male products.

Note: Enabling activity and gender recognition at the same time will increase the deduction for each test (charged per test, unit price is different). It is recommended to test in small batches first, and then execute on a large scale after confirming the data quality.

How to deduplicate data? What is the role of cross-task number deduplication warehouse?

After generating or importing numbers from different channels multiple times, duplicate numbers may easily appear. Repeated submission of screen numbers will cause a waste of balance. KK-DATA’s built-in data deduplication warehouse can help you solve this problem automatically.

How to use deduplication warehouse

• In the “Data Deduplication” module of the console, you can create a warehouse and merge multiple batches (generated results, imported old data).
• The warehouse will automatically identify duplicate numbers (judged by country code + number) and keep unique records.
• Then use the deduplicated number list as the input of the screening task to avoid repeated detection of the same numbers.

Set task-level deduplication rules

When submitting the screening task, you can also select the “Skip historical detected numbers” option. The system will automatically compare historical detection records, skip those numbers that have been detected on this platform, and only screen new/undetected numbers, thereby further saving balances.

Key point: There is no additional charge for the deduplication warehouse function itself, only the screening tasks are charged based on the number of detected items. Duplicate numbers will not be detected again after deduplication, thus avoiding repeated deductions.

Export filtering results: field interpretation and usage skills in CSV, TXT and other formats

After the screening task is completed, you can export the results file. KK-DATA supports CSV and TXT formats, among which CSV is more convenient for subsequent processing.

Common export fields and their uses

Field name	Meaning	Usage suggestions
phone	Number (international format, such as +1xxxxxxxxxx)	Use directly for WhatsApp private messages or import into CRM
country	country	confirm number ownership
platform	Detection platform (such as WhatsApp)	—
registered	Whether to activate (yes/no)	Filter available basic conditions
active	Whether active (yes/no) or active level	Core filters
last_seen	Last online time	Evaluate activity level
gender	Gender (male/female/unknown)	Used for targeted marketing
age	Age (e.g. 30 or age range)	Assisted crowd targeting
tgid/wsid	Internal ID of each platform	Used for advanced correlation analysis

Cleaning and formatting suggestions after exporting

1. Use Excel to filter: After opening the CSV, use the filter function to quickly mark the records with “Active = Yes” and hide invalid data.
2. Uniform number format: Make sure the number is in the international format (+1xxxxxxxxxx). Some mass sending tools require the ”+” to be removed or only the numbers to be left. Please convert according to the tool requirements.
3. Sub-file export: If you need to segment by gender or activity, you can save it in Excel as multiple TXT files.

FAQs and best practices for US WS active data acquisition

How to avoid filtering out invalid or fake numbers?

• Use dual verification of activation detection and activity detection.
• Do not use number lists from unknown sources without any testing.
• Regularly update the number database: data that has been imported for a period of time may be invalid. It is recommended to recheck it every 1-3 months.

Optimal size and recommended settings for a single batch

• It is recommended that a single number screening task should not exceed 1 million (the upper limit of the platform). If the number is larger, it can be submitted in batches.
• It is recommended to test on a small scale first (for example, 10,000 items), and then expand the scale after confirming the testing effect and cost. -Activity window setting: “Last 7 days” is recommended for the first try, which can balance quantity and activity.

Frequently Asked Questions (FAQ)

**Q: What is “US WS Active Data”? ** Answer: US WS active data refers to mobile phone numbers that have been tested and confirmed to be registered WhatsApp users in the US and have had online behavior in the recent past (such as within 7 days, 30 days). This type of data is often used for targeted reach in overseas marketing.

**Q: How to tell if a WhatsApp number is active? ** Answer: You can use the activity detection function of platforms such as KK-DATA. After submitting the number, the platform will return the last online time or activity level of each number. Users can customize the “active window” (such as the last 24 hours, 7 days, 30 days), and only numbers that meet the window will be marked as active.

**Q: How accurate is the gender recognition data? ** Answer: Gender recognition is inferred based on the platform’s public data (such as nickname, avatar, Bio, etc.) and is not bound to ID card information. The accuracy is usually between 70% and 90%. It is not recommended to be used in scenarios with extremely high accuracy requirements. Please refer to the console export field for actual results.

**Q: Can the filtered US WS numbers be used directly for WhatsApp group messaging? ** Answer: It is recommended to conduct an activity check first to confirm that the number is still valid and active before using it. At the same time, you need to comply with WhatsApp’s official anti-spam policy - the volume, frequency, content, etc. sent in a single day all have compliance risks, so please plan your sending rhythm appropriately.

**Q: Is there any charge for data deduplication warehouse? ** Answer: There is no additional charge for the data deduplication warehouse function itself. Only screening tasks are charged based on the number of detected items. Duplicate numbers will not be detected again after deduplication, thereby avoiding repeated deductions.
