Checklist before placing US TG numbers: source verification, format cleaning, activity detection and compliance operations

The U.S. TG number (i.e., the U.S. area code +1 number that activates Telegram) is the core customer acquisition resource for overseas marketing, cross-border e-commerce, and independent website promotion teams. However, many teams directly import the mass sending tools after getting the numbers, only to find that a large number of emails cannot be delivered, their accounts are blocked due to complaints, and their budgets are wasted. The reason often lies in: Lack of systematic checklist before launch.

According to statistics, the actual arrival rate of U.S. TG numbers without any cleaning may be less than 30%, including a large number of invalid numbers, unregistered numbers, low-activity numbers, and even spam numbers marked by Telegram. This article provides a complete checklist, covering source verification, format cleaning, Telegram activation/activity detection, gender screening and compliance operations, to help you conduct a comprehensive quality control before launching.

What is a US TG number? Why do you need a checklist before launching?

“US TG number” refers to a number that starts with the US country code +1 and has been registered on Telegram. These numbers may come from self-generated, third-party purchases, public data capture and other channels. Failure to inspect before release will lead to three major risks:

High proportion of invalid numbers: A large number of numbers have not opened Telegram or have been logged out. Directly sending private messages is a waste of money.
Low activity and poor conversion: Even if the account is opened, if it has not been logged in for a long time (for example, more than 90 days), the open rate and reply rate will be extremely low, which will affect the ROI.
Compliance Risk: Frequently sending private messages to users who have not agreed to receive messages may trigger Telegram’s anti-spam mechanism and cause the account to be blocked.

Therefore, establishing a practical checklist is a standard action that must be completed before each launch.

Common sources of US TG numbers and their reliability assessment

Self-built vs. third-party purchase

Source Types	Advantages	Disadvantages and Risks
Self-built and generated	No additional purchasing costs; format controllable; number segments can be customized	Numbers need to detect activation status by themselves; generation level is limited; no ready-made data packages
Third-party purchase	A large amount of data is obtained at one time; usually after preliminary cleaning	The source is unknown and may be mixed with invalid numbers and duplicate numbers; it is difficult to verify the true activation rate; there are compliance risks (such as data theft)

Recommendation: Regardless of the source, it must be tested and verified. For numbers purchased by third parties, the supplier is required to provide test data of batch samples (such as activation rate ≥ 60%), and support returns or discounts.

How to judge whether the source is trustworthy?

Are there batch sample test data: Trusted suppliers will provide test results of the first 100 or 1,000 samples.
Whether it promises activation rate: If the other party guarantees “100% activation”, you need to be vigilant - because any number set may not be activated or invalid.
Whether returns and exchanges are supported: Regular channels usually provide a certain percentage of returns and exchanges (for example, if it is invalid within 5%, it can be exchanged).
Whether independent testing is allowed: A good supplier will encourage you to use small batch testing first, and then pay for it after verification.

US TG number format checklist (cleaning steps)

Format errors are the first hurdle that causes detection failure or API return errors. Please follow these steps to clean:

Unified to E.164 format: country code + 1, followed by 10 digits (excluding spaces, brackets, and hyphens). For example: +12025551234
Remove spaces, brackets, dashes, and periods: Use Excel’s SUBSTITUTE formula or text replacement function.
Remove duplicate numbers: Use Excel “Remove Duplicates” or data deduplication tool.
Check Digits: Confirm that all numbers are 11 digits (+1 + 10 digits) or 10 digits (if +1 is not included in Excel, a prefix must be added).
Filter valid number segments: Common number segments in the United States such as 212 (New York), 310 (Los Angeles), 415 (San Francisco), etc. can be reserved for the target area.

Consequences of format errors

Incorrect number format will cause the number screening system to fail to recognize it, or the Telegram API will return an invalid status, which will also increase additional detection costs. It is recommended to clean it with a formula or script before importing.

How to check whether the US Telegram number is activated (tg activation detection)

The activation test is to determine whether the number has been registered in Telegram. The detection principle is to return results through Telegram’s registration status API.

Operating steps (take KK-DATA as an example):

Log in to the console https://app.kkdata.cc/ Create a Telegram screening task.
Upload the cleaned number list (supports CSV/TXT, one line per item).
Select the test type: tg开通 (i.e. registered test).
Submit the task, and the system will automatically deduct the balance after completion and output the result.

Billing logic for activation detection

KK-DATA uses per-item deductions, and the balance will be deducted after the task is completed. There is no subscription package. After recharging, consumption is based on the actual number of tests. **The specific unit price varies depending on the detection type. Please log in to the console to view the real-time price. ** The estimated cost will be displayed before the task is submitted to avoid exceeding the budget.

When the activation rate drops below what level does the data set need to be replaced?

Based on actual experience, if the activation rate is lower than 60%, it is recommended to abandon the batch of ** and re-obtain or clean the numbers. The low activation rate means that most numbers are invalid, and even subsequent activity detection is of little significance. If the activation rate is between 60% and 80%, it can be combined with activity detection to further screen out high-value numbers.

US TG number activity detection: How to screen active users?

Activating the test only indicates that the number is registered with Telegram, but it does not mean that the user is still using it. Activity detection can further analyze whether the account has logged in or used recently. For example, the tg活跃 option can specify the last 7 days, 30 days, 90 days, etc. windows.

**Why is activity important? **

Only activate inactive numbers: the private message arrival rate is very low and may be classified as a “zombie account” by Telegram and not be pushed.
Users who have been active within 30 days: are 3-5 times more likely to open a private message than users who have been inactive for a long time.

Operation Suggestions:

In the Telegram screening task of KK-DATA, select both tg开通 and tg活跃 (for example, “Active within 30 days”).
After the task is completed, export the number with the “active” label for delivery.

Activity affects conversion

The more active the number, the higher the private message opening rate and reply rate. It is recommended to select “active within 30 days” as the default filtering condition during batch testing.

How do additional fields such as gender and age assist the delivery strategy?

KK-DATA’s Telegram filter also supports gender identification, and the output results include gender and age fields. Note: These fields are based on the analysis of user public information and are not ID card level accurate, but they can be used for crowd portrait reference. For example, the age field can help you filter out users around 30 years old, which is suitable for middle-aged workplace product promotion.

Usage Scenario:

Set different words or offers for men vs. women.
Target specific age groups (such as 25-40 years old) to make refined contacts.
Combine the geographical number segment of the US TG number (such as New York segment 212) for localized marketing.

Compliance considerations for U.S. Telegram number distribution

Telegram has strict restrictions on automated private messages, and violations may result in account restrictions or bans. Please be sure to follow the following compliance recommendations:

Control sending frequency: It is recommended that the number of private messages sent per day by a single account should not exceed 200, and the interval should be at least 3-5 seconds.
Use real avatars and profiles: Avoid using robot avatars and blank profiles to reduce the risk of being reported.
Provide an unsubscribe mechanism: Include options such as “Reply ‘STOP’ to unsubscribe” in the first message.
Priority will be given to active users detected using this number: Sending messages to users who have been inactive for a long time is more likely to trigger spam determination.
Verify customer service authenticity: KK-DATA official customer service only communicates through two-way contact robots https://t.me/kkdata_robot. Please do not believe the “customer service” claimed by other channels and beware of fraud.
