Building a Number Screening System for Small Teams: Efficient SOP for Offshore Teams of 5 or Fewer

Small offshore teams (5 people or fewer) often face challenges when launching Telegram and WhatsApp social media marketing: limited manpower, tight budgets, and disorganized workflows. Without a standardized number screening SOP, collaboration among a few people can easily devolve into “whoever is available uploads,” repeatedly checking the same batch of numbers, or wasting communication time on inactive numbers treated as high-quality leads. This article provides a ready-to-use small team number screening system operation guide, covering team division, number preparation, screening process, data deduplication, and cost control.

Why Does a Small Team Need a Number Screening SOP?

With limited resources in a small team, each person often juggles multiple roles. Without a standardized screening process, several typical problems arise:

Duplicate submissions: Member A tested 10,000 numbers in the morning, and Member B imports the same file in the afternoon, resulting in multiple deductions from the balance.
Inconsistent test types: Some only select “TG registered,” others only “WhatsApp valid,” leading to incomplete export fields and difficulty in correlating data during later reviews.
Data chaos: Exported results from multiple people are scattered across local machines without a unified repository, requiring time-consuming re‑comparison and deduplication.
Uncontrolled costs: No budget awareness; submitting hundreds of thousands of numbers at once drains the balance quickly without knowing where the money went.

A standard number screening SOP (Standard Operating Procedure) solves these problems: define roles, fix processes, automate deduplication, and conduct monthly reviews. The result is a screening capability that is handover‑ready, quantifiable, and optimizable.

Team Division and Role Assignment

For a team of 5 or fewer, it is recommended to assign three roles. One person can take on multiple roles, but responsibilities should be clear.

Data Collector – Responsible for number list preparation and import

Number sources: Global number generation, purchased/provided number lists, CSV import.
Task: Prepare number files for each screening round according to the plan, ensuring correct format (one number per line, plain digits or with international prefix).
Note: Do not prepare the same batch of numbers repeatedly; use the “data deduplication repository” mentioned later to mark already tested numbers.

Screening Operator – Responsible for creating tasks, selecting test types, and exporting results

Use the console to create screening tasks, select platforms (Telegram/WhatsApp/iMessage, etc.) and test types.
Monitor task progress, enable Telegram notification (automatic push when task completes).
Export screening results (CSV/TXT), storing them by fields (active, gender, tgid, etc.).

Result Reviewer – Responsible for analyzing data quality and optimizing strategies for the next round

Summarize exported data weekly, calculate the “efficiency rate” for each type (e.g., proportion of WhatsApp valid numbers out of total submitted).
Adjust the next round’s number generation strategy based on insights (e.g., focus on a specific country’s number range, or increase activity detection).
Document lessons learned and update the team’s SOP document.

Number List Preparation Strategy: Generate or Buy?

For budget‑sensitive small teams, the method of acquiring numbers directly affects screening costs. Below is a comparison of the two main approaches:

Method	Advantages	Disadvantages
Global Number Generation	Free generation; can randomly generate numbers from 240+ countries/regions, or use global number ranges; extremely low cost	Some numbers may not be registered, requiring subsequent screening verification
Purchase/Provided Numbers	Clear source (e.g., collected at trade shows, existing customer lists)	Higher purchase cost, possible duplication or invalid numbers

For small teams, I strongly recommend prioritizing global number generation as an initial sample to accumulate a batch of “registered/active” numbers at minimal cost. On the KK-DATA platform, number generation is completely free; only subsequent screening tests are charged per entry. This way, you can first generate large batches of numbers using the generation module, then filter high‑quality numbers through screening tasks.

Using Global Number Generation to Reduce Initial Costs

Steps (see the “Number Generation” page in the console):

Select target country or region (e.g., India, Indonesia, Brazil – popular offshore markets).
Choose random generation or range generation (enter the first few prefix digits).
Set the quantity (suggest 5,000–10,000 at a time for easier testing).
The system generates the list; you can download it as CSV or import it directly into a screening task.

Important Notes for CSV Import of Custom Numbers

If your team already has an existing number list (e.g., from trade shows or purchases), ensure:

Unified number format: international format, no spaces, parentheses, or hyphens. For example 8613800138000 or +8613800138000.
File encoding is UTF-8 or UTF-8 BOM to avoid garbled characters in Chinese environments.
The console supports up to approximately 1 million numbers per single upload; we suggest small teams start with tests under 100,000 to get familiar with the process.

Detailed Step‑by‑Step Screening Process

Below are four major steps executable by a 5‑person team, each with a checklist.

Step 1: Create a Screening Task (Select Platform, Upload Numbers)

Log in to the Console and go to the “Screening Task” module.
Click “Create Task”, select the platform (Telegram, WhatsApp, iMessage, RCS, etc.).
Upload the number file (CSV/TXT), or import directly from the “Number Generation” module.
Checklist:
- File format correct, no empty lines.
- Correct platform selected (e.g., for Telegram activity detection, do not choose WhatsApp).
- Estimated cost within budget (the system displays estimated number × unit price before submission).

Step 2: Select Test Types (TG Registered/Valid/Active/Gender, WhatsApp Valid, etc.)

Each platform offers different test types; check the ones you need:

Telegram: TG Registered (account exists), TG Valid (can receive messages), TG Active (activity in last 7/15/30 days), Gender Recognition (AI‑based on avatar or nickname), TGID export.
WhatsApp: WA Valid (number registered on WhatsApp), WSID export.
iMessage / RCS: Registered/Active detection (details in the console).

Best practice: For initial marketing, at least select “TG Valid” or “WhatsApp Valid”, then add “TG Active” to improve contact hit rate. If targeting a specific gender, check gender recognition for further filtering.

Step 3: Submit Task and Monitor Progress (Balance Estimate, Telegram Notification)

Confirm sufficient balance before submission (the console shows current balance and estimated fee).
After submission, the task enters the queue; the page displays real‑time progress (Processing/Completed).
It is recommended to enable Telegram notification: in “Settings”, bind your personal TG account. You will receive a reminder when the task is completed, eliminating the need to constantly watch the page.

Step 4: Export and Analyze Results (CSV/TXT, Filter by Active/Registered/Gender Fields)

After the task is completed, click “Export Results”.
Choose format (CSV is common and opens directly in Excel; TXT is suitable for plain number lists).
The exported file includes number, test status (Y/N), gender (M/F/Unknown), tgid/wsid (if available), and test time.
Data analysis: filter numbers with status “Active” and matching target gender, save them separately in a “Quality Leads” folder.

Data Deduplication Repository: Avoid Wasting Balance on Repeated Tests

The most common waste for small teams is duplicate testing. For example, you test 10,000 numbers today, forget about it next week, import the same file again, and the system charges you again.

KK-DATA’s “Data Deduplication Repository” feature automatically avoids this problem: all tested numbers are recorded in the repository. When the same batch is submitted again, the system automatically skips numbers that have already been tested, and no longer charges for them.

Why Deduplication?

If the same batch of numbers is submitted in different tasks, the balance is deducted multiple times. By enabling the deduplication repository, the system automatically skips already tested numbers, saving at least 10%–30% per task.

Operation tips:

In the console’s “Data Deduplication” page, enable global deduplication (or enable per task manually).
Establish a team rule: all numbers must first be checked against the repository to see if they have been tested; only untested numbers should be submitted.
Periodically clear the repository (optional), but for small teams, it is recommended to keep it long‑term to save more costs.

Cost Control and Billing Reminders

KK-DATA uses a no subscription, pay‑per‑entry model, ideal for small teams:

Top‑up: minimum about 50 USDT (TRC20), no monthly/annual fees.
Charges: only when a screening task is completed; the balance is deducted based on actual tested entries × unit price.
The estimated fee is displayed before task submission, so you know the cost upfront.
All platform unit prices are based on the console’s real‑time prices; do not rely on historical screenshots.

Balance Attention

Please confirm sufficient balance before submitting a task. If the balance is insufficient, the task cannot be submitted. After topping up USDT, the balance updates automatically — no need to wait for manual approval.

Best practices for small‑team cost management:

Set a monthly budget (e.g., 200 USDT per month for screening) and stay within that balance.
Set a per‑task limit (e.g., no more than 50,000 numbers per task) to avoid exhausting the budget in one go.
Review costs weekly, calculate the average cost per qualified number, and optimize the combination of test types.

Frequently Asked Questions

Q: What is the minimum top‑up for a small team to start?
A: The minimum top‑up is about 50 USDT (TRC20). Charges are based on tested entries, with no subscription threshold. 50 USDT is enough for a small team to test a few thousand to tens of thousands of numbers.

Q: What is the maximum number of numbers that can be submitted in one screening task?
A: A single task can submit up to approximately 1 million numbers. We recommend small teams start with tests under 100,000 to get familiar with the process, then scale up. The queue supports parallel submission of multiple tasks.

Q: Can I test Telegram and WhatsApp simultaneously?
A: Yes. You can upload the same number list and create separate screening tasks (selecting TG or WA test types). The system supports cross‑platform parallel processing. Note that each task is billed independently.

Q: What fields are included in the export?
A: The CSV format includes number, platform test status (registered/valid/active/gender, etc.), tgid/wsid (if available), and test time. For exact fields, please refer to the export page in the console. You can customize the fields you want to export.

Q: How do I ensure that multiple team members don’t cause duplication?
A: Designate one person to submit screening tasks and use the data deduplication repository feature to automatically filter already tested numbers. You can also check via the task history in the console. If you are short‑handed, all members can operate under the same console account (pay attention to security), or use separate accounts but share the deduplication repository.

Next Steps: Log in to the Application Console and try creating your first screening task. If you encounter any issues, refer to the Documentation or contact customer support via Telegram @kkdata_cc.
