Guide to regional screening of active WS numbers in the United States: Plan your customer acquisition tasks according to the East, West, South and Midwest

When developing the US market, obtaining batches of US active WS numbers (that is, WhatsApp numbers that have been activated in the US and have been online recently) is the first step for many overseas teams. However, if we only perform a general filtering task based on the national dimension of “United States”, we often ignore the significant differences in user behavior among the four major geographical regions in the United States. Directly pulling numbers across the United States for private messaging without distinguishing between the east, west, south, and mid-west, which can easily lead to uneven open rates and response rates, and waste a lot of costs.

This guide will share how to use a number screening platform such as KK-DATA, combined with regionalized number segment generation, activation detection and activity detection, to produce an accurate list of US WS active numbers to improve overseas marketing ROI.

What is a US active WS number? Why do we need to plan by region?

US active WS number refers to a number that is located in the United States (country code +1), has successfully registered a WhatsApp account, and is online within the specified time window (such as the past 7 days or 30 days). This type of number usually has immediate reach potential and is suitable for private message promotion, community invitations or customer return visits.

Many marketing teams will mix numbers across the United States and place them together. However, this approach usually has two problems:

• Time zone confusion: Eastern time is 3 hours earlier than Western time. If the message is sent uniformly at 10 a.m. in the Eastern United States, users in the Western United States may still be in the early morning. This will result in a significantly lower private message open rate for Western numbers.
• Invalid reach costs are high: Users in different regions accept messages at different times. For example, a tech worker in the West might check their phone at noon, while a retail store owner in the South might be more active in the evening hours. Numbers that have not been regionally filtered can easily be judged as spam messages, which will affect the health of subsequent number pools.

Therefore, planning screening tasks according to the four major regions of the United States: the eastern, western, southern and midwestern regions is an indispensable part of refined operations.

Differences in number characteristics and customer acquisition in the four major regions of the United States

There are significant differences in population distribution, business activity periods, and social media usage habits among the four major regions in the United States. Understanding these differences can help you set up different number screening strategies.

East vs. West: High-density metropolitan areas vs. technology and Internet agglomerations

• Eastern (centered on New York, Boston, and Washington, D.C.): The financial, legal, and education industries are concentrated. Users work early (8:00-9:00 US Eastern Time), and the peak hours of replying to private messages are during the lunch break (12:00-13:00 US Eastern Time) and after get off work (US Eastern Time 17:00-19:00). If your target group is financial white-collar workers or corporate decision-makers, it is recommended to set the active window to the morning or noon of the Eastern United States on weekdays.
• West (centered on California, Seattle, and Portland): Technology and Internet companies are densely populated, and users work late. Workday mornings are often in a state of sorting, and the afternoon (13:00-15:00 USW) and evening (20:00-22:00 USW) are the time to actively check news. For marketers or software engineers at technology start-ups, choosing numbers with late active periods is more effective.

South and Midwest: Emerging Markets and Blue Ocean Regions

• South (centered on Texas, Florida, and Georgia): In recent years, there has been a large net inflow of population and rapid economic growth. The retail, real estate, and logistics industries are developed. Users in this region are relatively tolerant of messages, but the peak demand season is often concentrated around US holidays (such as Black Friday and Christmas season). If your product is related to consumer retail or real estate, you can preferentially filter southern numbers and set a longer active window (such as the past 14-30 days) to cover more users who have a replacement cycle.
• Midwest (centered on Illinois, Ohio, and Michigan): The traditional manufacturing, agriculture, and automobile industries have a solid foundation. Users’ social usage habits are relatively traditional, and private message opening rates are affected by local economic fluctuations. For example, during the agricultural harvest season or the peak season for manufacturing orders, users in this area may be busier and the message response rate will decrease. When screening, the active window can be appropriately shortened to 7 days to ensure that the number is active.

How to use KK-DATA to generate and filter active WS numbers by US region?

The KK-DATA platform provides two modules: “Global Number Generation” and “Global Number Filtering”, which support locking regions by country, number segment, and even customized CSV import. The following is a three-step process to help you generate a regionalized US active WhatsApp number.

Step 1: Generate the target area number segment

After logging in to the console, enter the “Global Number Generation” module.

1. Region selection: Select “United States” as the country (+1).
2. Lock the area: There are two methods.
   • By area code/first 3 digits: For example, New York’s area code starts with 212, 917, 646; Los Angeles starts with 310, 213, 323; Dallas starts with 214, 972; Chicago starts with 312, 773. You can enter these area code prefixes manually or select from a list of US state code segments provided in the console.
   • Customized CSV import: If you already have a list of numbers belonging to a known region, you can directly upload the CSV file, and the platform will automatically identify and skip duplicate numbers.
3. Generation quantity: The number of numbers generated each time is determined based on the USDT balance and the scale of subsequent number screening tasks. The entire generation process is free, no deductions will be made.

Step 2: Filter WhatsApp activated + active numbers

Import the number generated in the previous step into the new task.

1. Enter the “Global Number Filtering” module and select the country “United States”.
2. Detection type: Turn on “WhatsApp activation detection” and “WhatsApp activity detection” (additional activity windows can be set, such as the past 7 days, 14 days or 30 days). The platform supports a maximum of about 1 million numbers for a single task. If the number is large, it is recommended to submit it in batches by region.
3. Estimated Fee: The system will display the estimated deduction amount for this task before submission. The cost is calculated based on the number of tests, and the unit price is different on different platforms (WhatsApp, Telegram, etc.). For details, see the real-time price on the console.

Step 3: Export the results and re-import them into the database

After the task is completed, select “Export” in the task list. The format can be CSV or TXT. The exported fields include number, status (activated/not activated), active status (active days range), etc.

It is recommended to name the results exported from different regions separately (for example, “east_us_ws_active_30d.csv”) and store them uniformly. If there are other tasks in the future, remember to use the platform’s “data deduplication warehouse” to deduplicate across tasks to avoid repeated detection of the same number and save balance.

Best practices and considerations for splitting tasks by region

1. Submit in batches: If the total number of numbers in the United States is large (for example, 2 million), it is recommended to first run 500,000 numbers in the east, and then 500,000 numbers each in the west, south, and mid-west. Batch management facilitates comparison of activity differences in various regions, and also prevents one task data from being too complex.
2. Uniform active window: In order to control variables, it is recommended that all regions use a unified active window (such as 14 days), so that the data will be fairer during comparison.
3. Tag management: When exporting CSV, you can add a column of “region” fields in the table (marked manually or corresponding by number segment), so that subsequent private message tasks can allocate different words and sending times by region.

Typical application scenarios of regionalized US active WS numbers in overseas marketing

1. Finance + LinkedIn dual channels to reach white-collar workers in the east: Screen active WS numbers in the east, and use LinkedIn InMail to carry out private messaging + social contact for professions such as investment consultants and insurance brokers to improve trust and response rates.
2. Zalo+WhatsApp hybrid customer acquisition southern immigrant community: There are a large number of Hispanic and Asian immigrants in the southern United States. Zalo numbers in the southern region can be screened (with Line or Zalo screening modules), and then combined with WhatsApp to cover a wider range of people.
3. TG+WhatsApp combination reaches western technology start-ups: Screen active WS numbers on the West Coast (California, Washington State), supplemented by Telegram screening numbers (activation + active detection), used to invite members to join product internal testing groups or online seminars to increase participation rates.
4. RCS+traditional SMS bridges manufacturing customers in the Midwest: Manufacturing practitioners in the Midwest may have low acceptance of WhatsApp, but they can use RCS (Rich Media Communication) or regular SMS to get there. First locate these numbers through WhatsApp active detection, and then send product manuals or coupons in the form of RCS in private messages to achieve a better reach rate.

FAQ

**Q: Are there differences in the activity of active WS numbers in the United States in different regions? **

Answer: Yes. Generally, the eastern and western metropolitan areas have higher user activity, while some areas in the south and central and western regions may have time differences or low activity periods. It is recommended to set a unified active window (such as within 7 days) when filtering KK-DATA, and then compare the results by region.

**Q: How to ensure that the filtered numbers belong to a specific state or city? **

Answer: You can lock the region by customizing the number segment by state/region (such as the first 3 digits of the area code) during “Global Number Generation”, or import your own CSV (known place of origin) for filtering. The KK-DATA generation module supports 240+ country code segments, covering all states in the United States.

**Q: How many numbers can be processed at most in one task? **

Answer: The upper limit of a single detection task is about 1 million. If you need to cover the four major regions in the United States, it is recommended to submit multiple times by region to avoid exceeding the upper limit or making the data too large and difficult to manage.

**Q: Does the filtered number contain personal privacy information (such as name, avatar)? **

Answer: KK-DATA’s WhatsApp screen number only returns the activated/active status and does not provide user avatars, nicknames and other privacy fields (the gender field is only optional in the Telegram screen number part). Please comply with local data regulations and use the results appropriately.

**Q: What are the recharge and billing methods? **

Answer: There is no need to subscribe to the package. Recharge USDT (TRC20, minimum about 50 USDT) to the balance. After the screening is completed, the fee will be deducted according to the number of tests. Different platforms (WhatsApp, Telegram, etc.) have different unit prices. The real-time price of the console shall prevail.
