8-Point Checklist Before Submitting a Number Screening Task: Eliminate Inefficient Consumption and Boost Lead Generation Efficiency

In the process of overseas lead generation, Telegram and WhatsApp number screening is a critical step to verify the validity of numbers. Many teams only realize after submitting a screening task that the list format is wrong, the balance is insufficient, or the detection type is selected incorrectly, resulting in task rejection, duplicate charges, or wasted time. To avoid these pitfalls, we have compiled a pre-submission checklist to help you quickly verify 8 key points before each operation. Whether you are a beginner or a veteran, spending 3 minutes going through this checklist can significantly improve screening efficiency and reduce unnecessary costs.

Why Do You Need a Checklist Before Submitting a Number Screening Task?

A clear checklist delivers three core benefits:

1. Avoid duplicate charges: If the number format is wrong, the system may filter them out without charging, but resubmission still occupies the task queue; if deduplication is not enabled, the same batch of numbers may be detected repeatedly, wasting balance.
2. Prevent task rejection by the system: Errors like insufficient balance or mismatched number source can cause immediate task failure, preventing it from entering the queue.
3. Save rework time: A small oversight (e.g., missing the international prefix) may force you to redo the entire task, while a checklist helps you avoid it in one go.

Regardless of the screening platform you use, developing the habit of “check before submit” is a best practice. The following checklist uses KK-DATA as the core example, but most principles apply to any screening tool.

Checklist Step 1: Confirm Number List Format and Source

The correct number format is the foundation of a successful task. Make sure to:

• Include international prefix: e.g., 8613800138000 (China number). Do not write 13800138000 or +8613800138000 (the system usually handles + automatically, but pure digits are safest).
• No spaces, hyphens, brackets, or other separators: 86-138-0013-8000 or 86 138 0013 8000 are not acceptable.
• Only digits: Do not include letters, commas, or characters other than line breaks.
• Supported file types: CSV or TXT, one number per line (or per column). Excel files need to be saved as CSV.

Common Format Errors and Corrections

Error Type	Example	Correction Method
Missing international prefix	13800138000	Manually add 86, or use formula ="86"&A1
Contains +	+8613800138000	Find and replace + with nothing
Contains spaces/hyphens	86 138 0013 8000	Use CTRL+H to replace spaces/hyphens with nothing
Excel scientific notation	Long number becomes 1.38E+10	Set cell format to “Text” before pasting, or save as CSV with “UTF-8”
Contains blank lines or non-number text	Includes headers, description	Delete irrelevant rows, keep only the number column

How to Obtain Compliant Numbers via the Global Number Generator

To avoid manual errors, we recommend using KK-DATA’s “Global Number Generator” (free, no balance consumption). Simply:

• Select the target country: covers 240+ countries/regions, supports number range generation.
• Set the number count: the system automatically generates numbers in international format and exports to CSV/TXT.
• You can also import a custom number range CSV: the platform automatically verifies the format and creates a compliant number library.

Numbers obtained this way naturally meet screening requirements, allowing a smooth “generate → screen → export” pipeline that minimizes human errors.

Checklist Step 2: Confirm Sufficient Balance and Understand Estimated Cost

KK-DATA charges per number, with no subscription plans. Before submitting a task, you must confirm two things:

• Is your account balance greater than the task estimated cost?
• What is the unit price for the selected detection type? (See real-time prices in the console)

How to View the Task Estimated Cost in the Console

On the task creation page, after you select the number file and check the detection type, the system displays an “Estimated Cost” field. It automatically calculates based on the number count and each detection type’s unit price. For example, selecting both “Telegram Valid” and “Telegram Active (7 days)” will stack the costs. Carefully verify to avoid overcharging due to missed selections.

What to Do If Recharged Balance Doesn’t Show Up?

USDT recharges usually arrive automatically (TRC20 network). If it hasn’t appeared after 15 minutes:

• Check that the transaction hash is successful.
• Contact official customer service @kkdata_robot and provide the recharge record for inquiry.
• Note: The only official customer service is this Telegram account; beware of impersonators.

Checklist Step 3: Confirm Screening Platform and Detection Type Match

Different platform detection options require numbers to meet basic platform requirements:

• Telegram screening: Numbers must be mobile numbers (with international prefix), and the corresponding Telegram user must be registered on that number. The platform’s “Valid” check determines whether the number has registered Telegram; “Active” requires the user to have online activity within a certain period.
• WhatsApp screening: Numbers need to be mobile numbers and the country must support WhatsApp. If your number is a landline or from a country where WhatsApp is banned, even “Valid” will return invalid.
• iMessage / RCS: Requires Apple devices or Android devices with carrier support, respectively.

Common mistake: Using a batch of Indian mobile numbers to check WhatsApp validity (India has high WhatsApp adoption, so it’s fine), but using the same batch for iMessage will yield all invalid. So before submitting, ensure the target platform matches the number source.

Checklist Step 4: Check Activity Window and Gender Identification Settings

If your marketing scenario requires distinguishing user activity (e.g., only messaging users active within 7 days), or you want to target by gender (e.g., prioritize female users), you need to explicitly check the corresponding options when submitting the task.

• Activity window: Options include 7 days, 15 days, 30 days, etc. Shorter windows yield “hotter” numbers but usually come with higher unit prices.
• Gender identification: Based on AI recognition of Telegram profile pictures, not 100% accurate (avatars may be cartoons, pets, etc.). Use for reference only, especially with large number batches. Avoid over-reliance on small samples.

Note: Activity detection and gender identification consume extra balance. If you don’t need these dimensions, you can only check “Valid” or “Active” to save costs.

Checklist Step 5: Enable Data Deduplication to Prevent Repeated Checks

KK-DATA provides a data deduplication warehouse that automatically filters numbers already detected in previous tasks. Once enabled, the same number will not be charged again.

Prerequisites and Limitations of the Dedup Warehouse

• Deduplication only applies to completed detection results under the same account.
• If a number enters the warehouse for the first time, it is charged normally; if already present, no charge.
• If dedup is disabled or the warehouse is cleared, each detection will be charged per number.
• Cross-platform dedup? For example, numbers detected on Telegram and then submitted for WhatsApp detection are considered new numbers because the platforms differ, requiring re-detection and charging. Dedup only works for the same platform and same detection type.

For teams with long-term operations, keeping dedup enabled can save significant balance.

Checklist Step 6: Verify Export Fields and Format Requirements

After the task is completed, you need to export the results. Before submitting the task, think about which data fields you ultimately need and check the export options in the task settings.

Common export fields:

• tgid: Telegram user unique identifier, useful for precise message push or external system integration.
• wsid: WhatsApp ID, similarly applicable.
• Activity date: Last active time.
• Gender label: Male/Female/Unknown.
• Platform status: Valid/Invalid/Not registered.

Export formats support CSV and TXT. If you need to import these data into a CRM or process manually, CSV is more compatible. Confirm fields in advance to avoid rerunning tasks due to missing key information.

Checklist Step 7: Test with a Small Batch Before Running Full Task

This is the most effective way to reduce risk. For the first batch (e.g., 100–500 numbers), submit a small test task.

Purpose of testing:

• Verify number format correctness (if many format errors appear in the small batch, the invalid rate will be high).
• Observe whether the detection type executes as expected (e.g., whether activity is actually recognized).
• Confirm that the estimated cost matches the actual charge (small batch differences are minor and easier to debug).

If the small batch results meet expectations, then submit the remaining full batch; if issues arise (e.g., format errors, detection type mismatch), adjust and resubmit a small test. This avoids wasting thousands of problematic numbers submitted at once.

Checklist Step 8: Confirm Telegram Notification Is Bound

To receive timely task completion notifications (instead of manually refreshing the page), it is recommended to bind Telegram notifications. In KK-DATA’s console under “Notification Settings”, enter your Telegram Chat ID (usually obtained via @kkdata_bot), and you’ll receive a message when the task completes.

Why it’s important:

• Screening tasks may take minutes to hours (depending on number volume and queue), so you can’t keep staring at the screen.
• Upon notification, immediately download results and start subsequent marketing actions, reducing wait time.

Additionally, make sure to follow the official channel @kkdata_channel and customer service @kkdata_robot for system announcements and support. Note: the official team will never DM you asking for transfers; beware of impersonation scams.

Frequently Asked Questions

Q: I realized my list format was wrong after submitting the screening task. Can I withdraw it?

A: Once a task is submitted and enters the queue, it cannot be withdrawn directly from the console. It is recommended to strictly follow the checklist before submission. If it has been submitted and not yet processed, you can try contacting official customer service @kkdata_robot to request cancellation, but success is not guaranteed.

Q: What if the estimated cost differs from the final actual charge?

A: The estimated cost is based on current unit prices and number count. The final charge is based on the actual number of numbers detected (some numbers may be filtered out due to format issues and not charged). If the difference is significant (e.g., over 10%), contact customer service for details.

Q: Is the Global Number Generator free? Can generated numbers be used directly for screening?

A: Yes, the generator is completely free and does not consume balance. Generated numbers are random and can be copied or exported as CSV/TXT for screening tasks. However, note that generated numbers may include dead numbers or unregistered users; actual detection will mark their status.

Q: Can the same number be detected repeatedly in different tasks? Will I be charged multiple times?

A: If the data dedup warehouse is enabled, the system automatically filters out numbers already detected (under the same account), so no duplicate charges occur. If dedup is disabled or the warehouse is cleared, each detection will be charged per number. It is recommended to keep dedup enabled to save costs.

Q: What is tgid/wsid export? How is it used?

A: tgid is the internal unique user identifier on Telegram, and wsid is the WhatsApp ID. Exporting these allows precise message push, user profile analysis, or integration with other systems, avoiding duplication or errors that may arise from relying solely on phone numbers. You need to check the export fields in the task settings in advance.
