Three-Step Number Screening Pipeline: Number Generation → Screening → Export, A Practical Guide for Efficient Customer Acquisition

In overseas marketing, obtaining valid target user phone numbers is only the first step. What’s more critical is the ability to quickly determine which numbers are real, usable, and active, and finally export data compatible with subsequent promotion tools. Many teams spend considerable time on fragmented manual verification and duplicate detection, resulting in low efficiency and high costs. The Number Screening Pipeline: Generation → Screening → Export integrated solution introduced today is the standard process to solve this pain point: complete number generation, multi-platform screening, data deduplication, and export in one go, avoiding number waste, reducing duplicate detection costs, and significantly improving customer acquisition efficiency.

Whether you are operating Telegram group growth, WhatsApp marketing campaigns, iMessage or RCS advertisements, this pipeline helps you go directly from a “number pool” to a “reachable user pool.” This article will break down the operation details step by step, along with a reusable checklist.

What is a Number Screening Pipeline? Why is the “Generate → Screen → Export” Integration Needed?

The number screening pipeline refers to connecting three stages—number preparation, validity checking, and result sorting—into a single automated workflow. The traditional approach is: purchase numbers externally → manually check on different platforms → deduplicate using Excel → then export. Each stage is isolated, prone to errors, and time-consuming.

Traditional Number Screening Process vs. Pipeline Operation

Comparison Dimension	Traditional Method	Pipeline Operation
Number Source	External purchase, high cost and uncontrollable quality	Free generation (random/prefix/import), on-demand production
Screening Method	Operate separately on each platform, repetitive work	One submission, multi-platform simultaneous screening (TG/WA/iMessage, etc.)
Deduplication Mechanism	Manual formulas or third-party tools, easy to miss	Built-in deduplication repository, automatic cross-task comparison, avoids duplicate charges
Export Efficiency	Multiple merges, chaotic fields	One-click export CSV/TXT, unified fields
Total Time	Hours or even days	Minutes to tens of minutes (depending on number volume)

From the comparison, the integrated pipeline centralizes previously scattered operations within a single console, each step closely linked to the next, significantly reducing manual intervention.

Which Scenarios Best Suit This Pipeline?

• Telegram Group Growth: Requires batch verification of whether numbers have Telegram, activity within the last 7 days, avatar gender identification, etc., then export tgid for group adding.
• WhatsApp Marketing Campaigns: Filter valid WhatsApp numbers, export wsid, directly connect with bulk messaging software.
• iMessage Campaigns: For iPhone users, filter numbers with iMessage enabled to avoid invalid sends.
• RCS Advertising: Check if numbers support RCS (Rich Communication Services) for emerging channel投放.
• Multi-market, Multi-account Operations: Serve users across multiple countries/regions, requiring number generation by country and separate screening.

Common features of these scenarios: large number base, high demands on timeliness and accuracy, and the desire to only pay for valid numbers.

Step 1: Number Generation – How to Quickly Obtain Target Number Library?

Number generation is the starting point of the entire pipeline. KK-DATA offers three methods, all completely free, with charges only applied during the subsequent “screening” step.

Random Generation: Batch Generate Numbers by Country/Region

This is the fastest method. In the “Number Generation” module of the console, select the target country/region (supports 240+ countries), set the desired quantity, and click generate. The system will randomly generate a batch of numbers based on the country’s number format, without containing real user information. Suitable for preliminary testing or large-scale cold starts.

Global Number Prefix Generation: Pinpoint Specific Prefix Ranges

If you want numbers concentrated within a specific carrier (e.g., Indonesia Telkomsel, Brazil Vivo) or within certain prefixes, use the prefix generation feature. The platform includes a global prefix database. You can first search for target country prefixes, then generate consecutive numbers under that prefix. Generated numbers are closer to specific carrier users, often resulting in higher screening validity and activity rates.

Custom Prefix CSV Import: Suitable When You Already Have a Number List

If you already have a batch of your own numbers (e.g., collected from past campaigns, purchased data), you can upload a CSV file directly. Requirements: first column contains numbers (including country code, format like 8613812345678), no header needed. The platform will parse and automatically deduplicate. Notes: CSV file encoding is recommended as UTF-8 to avoid garbled Chinese characters; number count should ideally not exceed 1 million rows; for larger datasets, import in batches.

Step 2: Multi-Platform Screening – How to Efficiently Check Number Validity and Activity?

After the number library is prepared, enter the “Number Screening” module. This is the billing step. Before each operation, an estimated fee is displayed so you know the cost upfront.

1. Select Screening Platform: Supports Telegram, WhatsApp, iMessage, RCS. You can select one or multiple simultaneously (multi-platform screening is completed in one task, but screening types for each platform need separate configuration).
2. Configure Screening Type (using Telegram as example):
   • Validity Check: Determine if the number is registered on Telegram.
   • Active Check: On top of validity, determine if the number can send/receive messages (not disabled/deactivated).
   • Activity Check: You can specify windows like 7 days, 15 days, 30 days to filter numbers with recent online activity.
   • Gender Identification: Identify user gender via avatar recognition; results return Male/Female/Unknown.
   • tgid Export: After passing screening, export the corresponding tgid (Telegram internal ID) for later growth scripts.
   • Similarly, WhatsApp supports validity check and wsid export; iMessage and RCS support validity/activity checks.
3. Submit Task: A single task can submit up to approximately 1 million numbers. For larger volumes, submit in batches. Before submission, verify “Estimated Fee”; insufficient balance will prevent creating new tasks (tasks already running will not be interrupted).
4. Wait for Results: After task completion, you can receive notifications via Telegram bot or refresh the console to view.

Tip: To improve screening efficiency, it’s recommended to first perform the “validity check” and then use only the valid numbers for activity or gender checks. Running all checks at once, while simple, consumes more balance.

Step 3: Export and Deduplication – How to Safely Obtain Usable Data and Avoid Duplicate Charges?

After the screening task is complete, you can preview results and export files on the “Task Details” page. Supports both CSV and TXT formats. Before exporting, you can select which fields to include: phone number, country code, tgid, wsid, activity status, gender, etc. It is recommended to maintain a field order compatible with your target tool.

Exported CSV/TXT files can be directly imported into CRM, email marketing platforms, Telegram/WhatsApp bulk messaging software. Ensure the field delimiter (comma or tab) matches the requirements of the target tool.

Common Mistakes and Best Practices in Number Screening Pipeline

After helping dozens of teams build their pipelines, we’ve summarized several common pitfalls.

Other common mistakes:

• Ignoring Activity: Only perform validity checks before sending, resulting in many numbers being registered but long inactive, leading to extremely low open rates. For scenarios requiring high reachability, at least choose 7-day or 15-day activity detection.
• Duplicate Screening of Same Numbers: Multiple tasks using the same number pool without enabling the deduplication repository, leading to continuous charges. Solution: Create a global project where all screening tasks share the deduplication repository.
• Incompatible Export Format: CSV files using comma delimiters, but some bulk messaging tools only accept tabs (TXT). It is recommended to read the target tool’s documentation before exporting, or convert results in Excel.
• Ignoring Gender Recognition Errors: Gender recognition is based on AI avatar analysis and is not 100% accurate (approx. 85-90% accuracy). Can be used in combination with other fields for comprehensive judgment, or as a supplementary reference.

Frequently Asked Questions

Q: Why is number generation free but screening charged?
A: Number generation simulates creation without actually checking number status; screening requires real checks on each number’s registration, validity, and activity on corresponding platforms, consuming server and operator resources, hence charged per number. See real-time unit prices in the console.

Q: What is the maximum number of numbers I can screen in one batch?
A: A single task can submit up to approximately 1 million numbers. For larger volumes, submit in batches and enable the data deduplication repository to avoid duplicates.

Q: Do the screening results include phone numbers, country codes, tgid/wsid?
A: Yes. After screening completes, you can choose to export in “raw phone number” format or “with tgid/wsid” format; specific fields depend on the screening type (e.g., Telegram validity check can export tgid, WhatsApp validity check can export wsid).

Q: If my balance runs out during screening, will the running task be interrupted?
A: No. Once a task is submitted and starts screening, it will run to completion normally and deduct the corresponding fee from your balance. However, if your balance is insufficient when submitting a new task, you will not be able to create one.

Q: Can I use the exported files in other marketing tools?
A: Yes. CSV/TXT formats are compatible with most CRM, email marketing, SMS platforms, and Telegram/WhatsApp bulk messaging software. It is recommended to check the field format requirements of the target tool before exporting.
