How does US active TG data improve the customer acquisition efficiency of local services? A guide to working with area codes, time zones and data validity

In the field of overseas marketing, the promotion of local services (such as door-to-door repairs, moving, cleaning, takeout delivery, etc.) highly relies on geographical accuracy. If a moving team in Brooklyn, New York, sends group messages to users across the United States or even non-U.S. users, it will not only waste the budget, but may also lead to account ban due to ineffective interruption. One of the core tools to solve this pain point is US active TG data - that is, filtered US numbers that have recently logged in on Telegram. This article will focus on area code matching, time zone windows and activity definitions, combined with the actual operation of the KK-DATA screening platform, to teach you step by step how to obtain high-quality American Telegram active numbers from scratch, and transform them into effective local service customer acquisition capabilities.

Why does US local service promotion rely on US active TG data?

At the heart of local service is “people nearby.” Telegram is a communication tool with high user activity in North America and has a mature community ecosystem. However, if you blindly send an inactive or non-local number, the conversion rate may be less than 1%. In contrast, using US active TG data (that is, filtering out US numbers that have opened Telegram and have been active recently) can achieve:

• Reduce invalid interruptions: Only users who actually use Telegram will see your messages.
• Increase the follower rate: Active users have a greater chance of viewing and replying to messages.
• Region controllable: Filter by area code to ensure that the audience is within the target city.

Comparison items	Blind group sending	Accurate screening (active TG in the United States)
Number source	Random collection or purchase of the entire database	Double screening based on activity + area code
Arrival rate	There may be a large number of unregistered or dead accounts	Almost 100% Telegram enabled
Conversion rate	Low (less than 1%)	Can be increased by 5-10 times
Cost	Seems cheap, but is a serious waste	Deduct according to item, pay for what you use

Therefore, establishing a customer acquisition process based on US active TG data is the preferred path for overseas local service teams to reduce costs and increase efficiency.

Three key elements of active TG data in the United States: area code, time zone and activity definition

To accurately reach U.S. Telegram users, you can’t just look at “whether it’s activated.” Three dimensions must be coordinated: area code determines the location of the number, time zone determines the sending time, and activity determines the user’s recent behavior. The collaboration of the three can ensure that every message is sent to the right person and at the right time.

How area codes match local service coverage

U.S. phone number area codes are different from U.S. postal codes (ZIP Codes) and usually directly represent geographic areas. For example:

• 212/917/347: New York City (Manhattan, Brooklyn, etc.)
• 310/424: Los Angeles and surrounding areas
• 214/469/972: Dallas-Fort Worth
• 305/786: Miami
• 773/312: Chicago

When selecting a target city, the area code corresponding to that city is given priority. Note: Number portability may result in the number area code not representing the current location, but statistically most users still retain their native area code, which is still of reference value for local service promotion.

Time zone window: let the message be delivered during the user’s active period

The continental United States spans four time zones (Eastern, Central, Mountain, and Pacific), and the time difference can be up to 3 hours. For example, it’s 9 a.m. Eastern time and only 6 a.m. Pacific time. If you send messages at the same time, you may disturb the other party in the early morning hours.

It is recommended to set the sending window according to the time zone of the target area code. Common correspondences:

• Area code 212 → Eastern Time Zone: Recommended sending period 10:00-12:00, 14:00-17:00
• Area code 310 → Pacific Time Zone: It is recommended to delay by 3 hours, such as 13:00-15:00 Eastern Time (equivalent to 10:00-12:00 Pacific)

After using KK-DATA to filter out the numbers, you can combine them with the tgid or numbers in the exported data and send them in batches by time zone in your own private messaging tool.

Activity window: Filter out American Telegram users who are actually using it

Not all numbers with Telegram activation are “active” numbers. An account that has not logged in for a year after registration has a very low probability of receiving private messages. KK-DATA’s TG filter function supports specifying active window, for example:

• 7 days active: There has been login behavior in the last 7 days, the user activity is high, and it is suitable for immediate marketing.
• 30 days active: Wider coverage, but slightly lower activity, suitable for brand warm-up or long-term conversion.

Activity is positively correlated with conversion rate. It is recommended to use the 7-day active window when acquiring customers for the first time, and then adjust according to the effect after testing.

How to get a high-quality American Telegram active number from scratch? (Generation + screening process)

The following is the complete pipeline taking the KK-DATA platform as an example: Generate → Filter → Deduplicate → Export.

US number generation: 240+ country number segments supported, free to use

KK-DATA provides global number generation capabilities, covering 240+ countries/regions. For the United States, it supports inputting number segments (such as 212, 310, etc.) by state or city to batch generate mobile phone numbers that match the area code. There is no charge for generation and can be generated in large quantities as “seed numbers”.

A more flexible way is Customized number segment CSV import: If you have a list of historical number segments in the target area, you can upload the CSV file to generate the number, and then enter the number screening process.

TG screen number: detect activation, activity, gender, export tgid

After the generated numbers are imported into the screening task, select the detection type:

• TG activation: whether to register Telegram
• TG Active: Specify active window (7 days/30 days, etc.)
• TG Gender: Returns gender, age range (such as “male, about 30 years old”), avatar and other fields
• TGID export: Obtain the unique ID of the Telegram user for subsequent private messages or community invitations

Multiple items can be checked at the same time for one task. It supports up to about 1 million numbers at a time, which is suitable for large-scale screening.

Practical case: Screening US active TG data for New York moving services

Scenario description (fictional example, not real customers): An overseas moving team plans to promote services to Brooklyn, New York, and its target customers are people living in Brooklyn who need to move. They did the following using KK-DATA:

1. Generate numbers: Enter the area code “718” (covering Brooklyn and Queens) on the number generation page to generate 10,000 US numbers in batches.
2. Filter conditions: Create a TG screening task, select:
   • Active window: 7 days
   • Gender: Male (due to the high proportion of male decision-making in moving scenarios)
   • Age: 25-40 years old (combined with the age range in the gender field)
   • Export fields: tgid, gender, active time
3. Result: A total of 1,200 numbers meet the conditions (activated + active for 7 days + male + 25-40 years old), exported to CSV.
4. Send private message: Send service introductions in batches according to the Eastern time zone window (10:00-12:00, 14:00-17:00).

Effect Comparison: Previously, the team randomly purchased numbers for mass distribution, and the fan-adding rate was about 0.3%; using filtered US active TG data, the fan-adding rate increased to 3.5%, and the cost was reduced by about 70%.

Cost control and data deduplication: avoid duplicate detection and waste of balances

KK-DATA charges on a per-item basis and will be deducted from the balance after each number screening task is completed. If you re-submit a number that has already been checked, additional balance will be consumed. To solve this problem, the platform has a built-in data deduplication warehouse function:

• Automatically match detected numbers across tasks and automatically skip when submitting tasks (no billing).
• Supports manual import of historical data and establishment of long-term deduplication database.

In addition, it is recommended: Test in small batches first, and then execute on a large scale. For example, first submit 100 numbers to observe the detection speed and result format, and then expand to 10,000 levels after confirmation.

Common misunderstandings: area code does not equal local, active does not equal instant online

Myth 1: The area code definitely represents the user’s current location In fact, number portability is so common that a user may have a 212 area code (New York) but have moved to Los Angeles. However, for local service promotion, the area code is still the lowest-cost geographical filtering indicator. If higher accuracy is required, it can be combined with IP testing or subsequent communication for confirmation.

Myth 2: “Active” equals “the user must be online when the message is sent” Activity detection is based on the time when the user last logged into Telegram, and is not online in real time. A 7-day active user may have logged in on a certain day this week, but there is no guarantee that he will be online when you send a message. This is a common limitation of all screening tools. It is recommended to cooperate with subsequent private message strategies (such as multiple contacts and scheduled sending) to make up for it.

Further stratification based on user profile fields such as gender and age can also effectively reduce the proportion of abnormal accounts (such as robots and short-term accounts).

Summarize the key steps from data to conversion

1. Demand Analysis: Clarify the cities/regions covered by the target service and lock in the corresponding area code.
2. Generate Number: Use KK-DATA to generate a US number with the target area code for free, or import a custom number segment CSV.
3. Filter active data: Create a TG screening task, set the active window (recommended 7 days), gender, age, etc., and perform batch testing.
4. Deduplication and Export: Use the data deduplication warehouse to avoid repeated deductions and export fields such as tgid, number, and active time.
5. Time zone batch: Set the sending period according to the time zone of the target area code, and use the exported tgid or number to send private messages.
6. Effect Review: Statistics of follower addition rate and reply rate, and adjust filtering conditions (such as narrowing the active window or changing gender orientation).

KK-DATA also provides a Telegram task notification function, which automatically pushes the results after the screening is completed, helping you obtain data as soon as possible and improve operational efficiency.

FAQ

Question: Can the active TG data in the United States be guaranteed to be used by real people?

Answer: There is no 100% guarantee, but KK-DATA’s activity detection is based on the login status returned by the Telegram server and can filter out non-registered or long-term unlogged numbers. It is recommended to further filter by combining gender, age and other fields to reduce the proportion of abnormal accounts. For high-value scenarios, it can also be combined with subsequent private message interaction for confirmation.

Question: How to confirm which US city/region a certain area code corresponds to?

Answer: It can be queried through the North American Number Assignment Database (such as NANPA). KK-DATA’s number generation page also provides instructions on the distribution of area codes in common countries/regions. In actual operation, small batch numbers of target area codes can be generated first, and the scale can be expanded after the screening numbers are confirmed.

Question: KK-DATA supports filtering the most recent active users?

Answer: Supports specifying active windows. Common options include 7 days, 14 days, 30 days, etc. Please check the console task configuration page for details. Select the 7-day window to get the users with the highest recent activity, which is suitable for immediate access; the 30-day window has a larger data volume, but the activity is slightly lower.

Question: What operations can the filtered tgid be used for?

Answer: tgid is the unique identifier of a Telegram user and can be used for automated operations such as sending private messages, adding friends, and inviting people to join groups (it needs to be coordinated with other legal tools). Note: Any batch operations should comply with Telegram’s terms of service to avoid harassment that may lead to account restrictions.

Question: Why do some numbers show “Not activated” in the screening results?

Answer: This indicates that the number has not been registered by Telegram and may be an empty number or a real mobile phone number that has not been registered on the social platform. These numbers will not be charged (only numbers that are successfully detected will be charged), but they will consume the processing quota in the task. It is recommended to give priority to active number segments during the number generation phase to reduce the proportion of invalid numbers.
