US valid TG number source acceptance score sheet: format completeness, duplication rate, activation rate and data freshness

In the process of acquiring customers overseas, valid US TG number is the cornerstone for entering Telegram communities and private message promotion. Whether you create them in batches through a number generation tool or purchase them from third-party channels, after obtaining a batch of numbers in batches, the biggest headache for operations is often not “do you have numbers?” but “how long and how much can this batch of numbers be used for?”

I have seen many teams spend a whole day sorting out a list of tens of thousands of American TG numbers. After submitting it to the screening platform, they found that half of it was in the wrong format, 30% were duplicates, and in the end, less than 20% of the numbers were actually opened for Telegram. This inefficiency not only wastes the screening budget, but also slows down the entire customer acquisition rhythm.

Therefore, it is crucial to establish a systematic acceptance criteria. The following set of Four-Dimensional Rating Table is specially used to evaluate the source quality of any batch of US valid TG numbers, covering format completeness, duplication rate, activation rate and data freshness.

Why is it necessary to accept the source quality of valid TG numbers in the United States?

Before going into the details, let’s first think about a question: Who generated the list of numbers you got? Are there any quality checks during generation or acquisition?

Many free or low-cost number sources often have the following fatal flaws:

• Confusing format: The number is missing the country code, or has spaces, brackets, or alphabetic characters mixed in.
• A large number of repetitions: The same number appears dozens or hundreds of times in the list. It seems that the number is large, but in fact it is reduced by half once dehydrated.
• Invalid accumulation: Most numbers have not been registered on Telegram, and the activation rate is extremely low.
• Old and dusty: The numbers are from a few years ago and many have been written off or are no longer active.

If you blindly submit the number screening task without checking and accepting it, you will consume a lot of balance on “invalid data detection” and end up with very few valid numbers. **A rigorous scoring table can help you filter out low-quality sources at once and spend money on the numbers most likely to convert. **

Scoring Dimension 1: Format Completeness - Can the number be recognized?

Format Completeness refers to whether the number complies with the international format specifications required by Telegram. For U.S. numbers, the format must include the country code + 1, followed by the full 10 digits, and cannot contain extra characters.

Example of format specification for valid TG numbers in the United States

Status	Example
✅ Correct format	+14151234567 or 14151234567
❌ Missing country code	4151234567
❌ Contains extra characters (brackets, spaces, minus signs)	(415) 123-4567, 415-123-4567
❌ Wrong number of digits	+1415123456 (10 digits) or +141512345678 (12 digits)

How to quickly detect format integrity?

The most direct method is to use a text editor (such as VS Code, Notepad++) with regular expression scanning:

• Search for ^\+1\d{10}$ to match correctly formatted numbers (with a + sign).
• Search for ^1\d{10}$ to match numbers without the + sign but with the correct number of digits.
• If it does not meet the above two conditions, the format is incomplete.

If you do not have the conditions to write regular expressions, you can use KK-DATA’s global number generation module for preprocessing: import your number list into the “custom number segment CSV import” function of the generation module, and the system will automatically verify and standardize the format. After the processing is completed, the file in complete format is exported and put into the screen.

What is the qualifying line for format integrity?

It is recommended to set the pass line to ≥95%. If the format integrity of a source is below this threshold, it indicates that the source is of poor quality and is either manually pieced together or collected from informal sources. Low format integrity directly leads to screen number detection failure or misjudgment because the platform cannot correctly identify the country and operator corresponding to the number.

Another issue that needs attention: high format integrity ≠ valid number. It is only the most basic entry threshold, and the real test is yet to come.

Scoring Dimension Two: Repetition Rate—How does uniqueness affect deductions?

KK-DATA adopts the per-item billing model: every screen number test (regardless of whether it is finally activated or not) will be deducted from the balance. So a list with a lot of duplicate numbers means you’ll be paying for multiple tests for the same number.

How to calculate repetition rate?

The formula for calculating repetition rate is very simple:

Repetition rate = (Total number of items - Number of items after deduplication) ÷ Total number of items × 100%

For example: You submitted 100,000 U.S. numbers. After being processed by Excel’s deduplication function or KK-DATA’s Data Deduplication Warehouse, you found that only 80,000 were actually unique. Then the repetition rate is (100000 - 80000) ÷ 100000 = 20%.

Best Practices for Low Duplication Rates

**The repetition rate is recommended to be less than 5%. ** If the duplication rate from a certain source exceeds 10%, I suggest you abandon the source directly, or actively remove duplicates before submitting.

Here is a detail that is easily overlooked: Cross-task deduplication. If you detect two batches of numbers A and B at one time, and use a batch of numbers that partially overlap with A and B in task C next time, if you do not remove duplicates across tasks in advance, these overlapping numbers will be deducted repeatedly.

KK-DATA’s built-in data deduplication warehouse can automatically identify and filter out numbers that have been detected in all historical tasks to avoid repeated deductions. Using this feature, you no longer need to manually compare multiple CSV files.

Scoring dimension three: activation rate - how many of these US TG numbers are actually valid?

Opening rate is the core indicator to measure the quality of a batch of US valid TG numbers. It directly tells you: out of 100 numbers, how many have been registered on Telegram and can be used normally.

How to measure the activation rate?

The simplest way to measure the activation rate is to use KK-DATA’s Telegram screen number (tg activation detection). You only need to submit a batch of numbers and wait for the task to be completed to view the “activated” proportion in the detection report. This test will return the registration status (yes/no) of each number and supports exporting fields such as tgid.

Industry experience reference value

The activation rates of US Telegram activation numbers from different sources vary greatly. Here are some reference ranges:

• Randomly generated new numbers (generated in batches based on number segments): The activation rate is usually around 20%–30%.
• High-quality old account numbers or simulated registration numbers: the activation rate can reach 50%–60%.
• “Guarantee” number purchased directly from gray production channels: You need to be wary of false promises and pay only after inspecting the goods.

The relationship between opening rate and source quality

The high activation rate indicates that the numbers generated by this source coincide with Telegram’s user pool. There is a high probability that these numbers will be valid for a long time. On the contrary, for sources with an activation rate lower than 20%, it is recommended to abandon them directly or use them as auxiliary supplements.

Scoring dimension four: Data freshness - is the number “live”?

A Telegram number has been registered, but if it has never been online or sent messages in the past three months, its value to you will be greatly reduced. Data freshness measures the “time active” of a number, usually measured by the date the number was last active or the date it was generated.

How to evaluate freshness through activity detection?

KK-DATA’s Telegram activity filter function can specify the activity window: for example, detect “tg active (7 days)” or “tg active (30 days)”. If you have a large number of numbers that need to be verified, it is recommended to do an activation test first, and then perform activity screening on the activated numbers.

The relationship between freshness and activation rate

Freshness status	Opening rate reference range	Recommended strategies
High freshness (active within 30 days)	35%–60%	Priority use, highest reach rate
Medium freshness (active for 30–90 days)	20%–35%	Can be used as a supplement, but effectiveness may be reduced
Low freshness (not active for more than 90 days)	10%–20%	Recommended to be discarded or only used for low-value testing

Numbers with high freshness not only have a high activation rate, but also have high user activity, and the probability of their private messages being read is greater. Ideally, you should only take numbers that have been active within 30 days to get the best US valid tg numbers quality.

How to use the scoring form to comprehensively accept a valid TG number in the United States?

Integrating the above four-dimensional scoring, you can develop a simple set of acceptance criteria to score or label all sources:

Dimensions	Eligibility criteria	Weight recommendations
Format Completeness	≥95%	Required
Repeat rate	≤5%	Required
Opening rate	≥30%	Core items
Freshness (active)	≥70% (active within 30 days)	Bonus points

If any item from a source does not meet the “required” criteria, it is recommended to reject it directly. If all four items meet the standards, then these numbers are high-quality US Telegram activated numbers and can be used for subsequent number screening tasks with confidence.

The acceptance results can also guide your screening strategy:

• The format integrity is not up to standard → standardize first and then filter the numbers
• The duplication rate is too high → Forced deduplication warehouse processing
• The opening rate is low → Increase the sample size or change the source
• Poor freshness → Add activity detection filtering

How to obtain high-quality American Telegram activation numbers in batches after acceptance?

Once you’ve verified one or two high-quality sources with a score sheet, it’s time to scale using KK-DATA’s “Generate → Screen → Export” pipeline:

1. Generate US numbers: Use the Global number generation module, select “United States” and the specific number range to generate massive numbers for free.
2. Deduplication and Preprocessing: Submit the generated or externally imported numbers to the Data Deduplication Warehouse to automatically remove duplicate records.
3. Submit screen number task: Select “Telegram screen number” in the console, add tg activated and tg active detection types, and the system will deduct fees per item.
4. Export filtering results: After the task is completed, download the list of valid TG numbers in the United States in CSV or TXT format, including fields such as activation status, active tags, and tgid.

The entire process is seamless, eliminating the need to manually move data between different tools. Since KK-DATA is a pay-by-item, no-subscription package, you can flexibly control the amount of testing according to your budget and pay for what you use.

FAQ

Question: What does “valid” specifically mean for a valid TG number in the United States?

Answer: Usually it means that the number has been registered in Telegram and is active, and can receive messages or join groups. KK-DATA’s “tg activated” test can determine whether it is registered, and “tg active” can further determine whether it has been used recently.

Question: What are the format requirements for opening a US TG number?

A: US numbers should contain the country code +1, followed by 10 digits, for example +1XXXXXXXXXX. Without +1 or with spaces, brackets and other characters, the format is incomplete, which may lead to detection failure or misjudgment.

Question: How high a repetition rate is considered normal?

Answer: It is recommended that the repetition rate be less than 5%. If the source duplication rate exceeds 10%, it is recommended to first process it through a deduplication tool or KK-DATA data deduplication warehouse, otherwise a lot of screening fees will be wasted.

Question: What is the typical activation rate?

Answer: The activation rate of randomly generated new US numbers is usually around 20%-30%; if you purchase high-quality numbers, it can reach 50%-60%. However, it needs to be tested in real time and there is no fixed number.

Question: How to obtain freshness data?

Answer: You can use Telegram activity detection, set the activity window (such as 7 days, 30 days), and only use active numbers. KK-DATA supports filtering by specifying active days to help determine the freshness of numbers.

If you are purchasing or preparing your own valid TG number in the United States, it is recommended to use the above rating form for acceptance first. KK-DATA provides free number generation, data deduplication and Telegram filtering functions, which can help you quickly judge the source quality and obtain high-availability numbers in batches.
