US data planning guide by region: Ideas for splitting tasks in the East, West, South and Midwest

Obtaining high-quality US data is a key step for overseas marketing and cross-border e-commerce customer acquisition. However, many teams directly import the national phone number list for screening, and find that the detection efficiency is low, the cost is high, and the user active time is misaligned with the promotion period. The reason is: There are significant regional differences in US data - number segment ownership, time zone distribution, platform penetration rate, and crowd portraits are different. Only by splitting tasks by geographical area can the accuracy of screening numbers and customer acquisition ROI be maximized.

Based on the number generation and screening functions of KK-DATA, this article will teach you step by step how to plan data tasks for the eastern, western, southern and midwestern United States, avoid invalid detection, and improve the reach of platforms such as Telegram and WhatsApp.

Why does US data need to be planned by region?

US phone numbers follow the NANP (North American Numbering Plan), and the first three NPA area codes directly correspond to the geographical area. For example, 201 represents northern New Jersey, 212 represents Manhattan, New York City, and 310 represents Los Angeles County. If you screen all numbers indiscriminately, you will encounter three problems:

1. Mismatch between number segments and regions: Some mobile phone numbers belong to virtual operators or cross-regional numbers, but most fixed area codes still point to specific states or cities. It is impossible to assess user density in different markets without grouping them by region.
2. Time zone differences lead to active window failure: The United States spans four major time zones: Eastern (EST), Central (CST), Mountain (MST), and Western (PST), plus Alaska and Hawaii. If a unified active time window is set (such as 8 pm to 10 pm), users in the eastern region may have fallen asleep, while users in the western region have just gotten off work.
3. Regional characteristics of platform penetration: Telegram is more popular in technology/encryption communities (West, Northeast), WhatsApp is more popular in Hispanic areas (Florida, New York, Texas), and iMessage is common across the United States but needs to be tested separately. Without distinguishing between regions, it is impossible to select a testing platform in a targeted manner.

Correspondence between US regions and number segments

To plan by region, the first step is to identify where the numbers belong. Common methods include:

• View the NPA area code table (please refer to NANP official resources or third-party database)
• Use KK-DATA’s “Global Number Generation” function, specify the United States and manually enter the target area code (such as 212, 310, 312, 404) to generate numbers in batches

For example, if you want to target customers in New York, you can generate a series of numbers starting with 212 or 646; if you want to target Los Angeles, use 310 or 323. The generated list is exported as CSV to prepare for subsequent screening numbers.

Linkage strategy between time zone and activity filtering

KK-DATA’s screening function supports customizing the “active window” - you can specify a time period (such as 19:00-22:00 every day), and the system will only detect users who are online during this period. If you want to promote across regions at the same time, the best practice is:

• Eastern mission: active window set to EST 9:00-12:00, 19:00-22:00
• Western mission: The active window is set to PST 9:00-12:00, 19:00-22:00 (i.e. 16:00-19:00, 22:00-1:00 UTC)
• South/Midwest: Use CST time, which is 1 hour behind EST and 2 hours ahead of PST

In this way, the tasks in each region cover the prime time hours of local users, avoiding disturbing sleep time and improving the acceptance rate.

How to generate target numbers by US East, West, South, Midwest?

KK-DATA’s “Global Number Generation” module is completely free and supports 240+ countries/regions, including the United States. The specific operation is divided into two steps.

Use number segment generator to target east/south/midwest

1. Log in to KK-DATA Console
2. Enter “Number Generation” → “Random Generation” and select the country “United States”
3. In the “Area Code/City Code” input box, manually fill in the target NPA area code, separated by commas:
   • East: 212 (New York), 617 (Boston), 202 (Washington DC), 215 (Philadelphia), etc.
   • South: 404 (Atlanta), 713 (Houston), 305 (Miami), etc.
   • Midwest: 312 (Chicago), 313 (Detroit), 614 (Columbus), etc.
   • West: 310 (Los Angeles), 415 (San Francisco), 206 (Seattle), etc.
4. Set the number of generated items (up to about 100,000 items each time), click Generate, and export CSV

If you want to generate by state, you can use the “number segment generation” mode and select a prefix list for a specific state (you need to prepare the number segment file in advance, or refer to the area code-state comparison table in the document).

Custom CSV import: Region filtering for existing lists

If your team already has a CSV file of U.S. phone numbers, but you don’t know which ones belong to the east and west, you can use KK-DATA’s “number prefix filtering” function:

1. Upload CSV in the console and select “Filter by prefix”
2. Enter the typical eastern area code (212, 201, 516, 617, 202, etc.), and the system will automatically extract the corresponding number subset
3. Repeat the operation to extract numbers from other regions.
4. Export to multiple files, each file corresponding to a geographical area

This method does not require knowing the location of the number in advance, and only needs to quickly split it according to the area code rules.

After the regions are split, how to configure the screening tasks more efficiently?

Comparing non-partitioning (one task processes all U.S. numbers) and partitioning multi-tasking, the difference is obvious:

Comparative dimensions	Single nationwide mission	Multiple missions by region
Cost	May contain a large number of duplicate or invalid number segments, wasting budget	Each task has a clear goal, and more savings will be achieved after deduplication
Speed	Single thread processing 1 million items, long waiting time	Submitting multiple subtasks in parallel, shortening the overall time
Data quality	The active window cannot be adjusted for different regions, and the results are rough	The time zone and platform can be set separately, and the data is more accurate
Subsequent use	It is difficult to analyze user portraits by region	Can be exported directly by region to facilitate targeted marketing

Practical suggestions: The number of each subtask number should be controlled within 100,000 (the maximum number of KK-DATA single tasks is about 1 million, but parallelization will be faster after splitting). For example, if you have 500,000 U.S. numbers, you can split them into 200,000 in the East, 100,000 in the West, 100,000 in the South, and 100,000 in the Midwest. Submit four tasks at the same time, and the total time is only equivalent to the time of the largest task.

Priority recommendations for different detection platforms in the United States

The penetration rate of platform in the US market is highly related to the regional demographic structure. You can refer to the following priorities before making decisions.

Differences in active regions between Telegram and WhatsApp in US data

• Telegram: Relatively popular in the tech/crypto community, West Coast (California, Washington State), Northeast (New York, Boston). Suitable for promoting technology products, developer tools, and cryptocurrency projects.
• WhatsApp: Hispanics, Asian immigrants, and family users have high penetration rates, especially in Florida, Texas, southern California, and New York City. Suitable for cross-border e-commerce, local life services, and tourism industries.
• iMessage: The proportion of iOS users in the United States exceeds 55% (data source: StatCounter), but the detection method is different (stability of iMessage reception needs to be detected). Can filter for high-end user groups (such as Apple device logo).
• Line: Mainly targeted at Japanese and Korean communities, with a small user base and only a certain base in Hawaii, Los Angeles and other places.
• Zalo: Areas with many Vietnamese users (such as San Jose, California, and Houston, Texas).

Strategic suggestion: First determine the target group profile, and then select 1-2 platforms with the highest penetration rate for testing. For example, for technology practitioners in California, priority is given to testing Telegram+WhatsApp; for Hispanics in Florida, testing is focused on WhatsApp.

Tips for interpreting gender/age fields for regions

KK-DATA’s Telegram/WhatsApp filter results include gender, age (some fields) and other information. Secondary screening can be done based on regional characteristics:

• West (such as California, Washington State): There is a high proportion of young people, you can use the age field to filter 18-35 years old; gender can be balanced (strong diversity).
• South (such as Texas, Georgia): There are more family users. You can focus on screening 30-45 years old, gender-biased women (household purchasing decision-makers) or men (manual labor industry).
• Midwest (such as Illinois, Ohio): The average age is slightly older, and you can focus on people aged 35-50.

Note: The accuracy of the age field is limited. KK-DATA does not promise ID card-level accuracy, but it can be used for large-scale trend judgment.

US data deduplication and cross-task collaboration

When you generate and split multiple area code files, there may be overlapping numbers (for example, a number belongs to the New York area code 212, but is misjudged to multiple area subsets due to carrier identification). In addition, if Telegram and WhatsApp are detected at the same time, the same number may be repeatedly detected and charged.

KK-DATA’s “Data Deduplication Warehouse” function can solve this problem:

1. Upload the CSV files of numbers in all regions to the deduplication warehouse
2. The system automatically identifies and marks duplicate numbers (based on the uniqueness of the number + country code)
3. Export the unique number list after deduplication
4. Submit screening tasks in batches

FAQ

**Q: Is it free to generate a number based on the US region? ** Answer: Yes. KK-DATA’s “Global Number Generation” module is free for use in 240+ countries/regions in the United States, with no limit on the number of times; fees will be deducted based on the number of tests only when the number screening task is submitted after generation.

**Q: How do I determine which US region my generated number belongs to? ** Answer: The first three digits of a U.S. phone number (NPA area code) represent the geographic area. For example, 212 corresponds to New York City, and 310 corresponds to Los Angeles. You can manually enter these area codes when KK-DATA is generated, or refer to the NANP official area code table.

**Q: Where is the recommended active window for U.S. data? ** Answer: It is recommended to set the “active window” according to the target region time zone. Eastern Time (EST) 9:00-12:00 and 19:00-22:00, Western Time (PST) is delayed by 3 hours, and the South/Midwest can refer to Central Time (CST). KK-DATA supports customizing active time periods.

**Q: What fields do the filtered US number data support for export? ** Answer: Depending on the detection platform, TG/WA/Line activation status, activity, gender, age (some fields), tgid/wsid, etc. can be exported. The specific results are subject to the console task results.

**Q: Can the generated eastern US numbers and western US numbers be merged to eliminate duplication and then screen? ** Answer: Yes. It is recommended to import the number files of each region into KK-DATA’s “Data Deduplication Warehouse”. The system will automatically identify duplicate numbers and submit the task after deduplication to avoid wasting budget.
