thdata Global Number Generation vs KK-DATA: A Comprehensive Comparison of Number Prefix Generation, Free Generation, and Filtering by Billing

For overseas customer acquisition teams, batch obtaining phone numbers from target markets is the first step in launching marketing campaigns. Whether it’s Telegram community promotion, WhatsApp direct messaging, or iMessage marketing, the primary task is to obtain a large pool of real or valid numbers. Global number generation tools have therefore become standard for overseas data operations. This article focuses on thdata Global Number Generation and KK-DATA, comparing them systematically across dimensions such as prefix coverage, generation methods, billing models, deduplication, and security verification, helping you make an informed choice based on your business stage.

Why Is Global Number Generation the First Step in Overseas Customer Acquisition?

In scenarios like B2B SaaS overseas expansion and cross-border e-commerce independent site promotion, marketers need to send messages to potential customers in specific regions. Buying ready-made number lists often carries three major risks: expired numbers, unknown sources, and being flagged as spam. Therefore, the standard workflow becomes: generate numbers independently → filter for validity → export usable lists.

• Random generation by country prefix: Quickly obtain massive numbers for large-scale outreach (e.g., Telegram channel member adding).
• Custom prefix import: Combine with existing industry databases (e.g., business directories) to generate numbers with fixed prefixes for higher hit rates.
• Post-generation filtering: Use operational checks (Telegram/WhatsApp activation, activity) to eliminate invalid numbers and reduce waste.

Both thdata and KK-DATA offer number generation capabilities, but differ significantly in coverage, billing structure, and supporting filtering features. Let’s analyze them one by one.

Global Number Generation Capability Comparison: Coverage Countries, Prefix Quality, and Generation Methods

Comparison Dimension	thdata Global Number Generation	KK-DATA Global Number Generation
Number of countries covered	Subject to actual list on official website	Random generation for 240+ countries/regions
Prefix source	Publicly available operator prefixes	Global prefix database continuously maintained + custom CSV import
Generation method	Country + operator selection (may have limitations)	Random generation / Global prefix generation / Custom prefix CSV import
Generation fee	To be verified (possibly per-use or per-quantity)	Completely free (generation does not deduct balance)
Max generation per batch	To be verified	Up to ~1 million records (when combined with filtering tasks)

Characteristics of thdata Global Number Generation

According to publicly available information, thdata offers number generation by country and operator, suitable for users with clear regional targets. However, the update frequency of its prefix database and whether it supports custom import are not clearly stated. If you only need prefixes for a few countries, thdata can be an alternative.

Characteristics of KK-DATA Global Number Generation

KK-DATA treats global number generation as a free entry-level feature, usable without any top-up. It supports:

• Random generation for 240+ countries/regions: Covers most overseas target markets, including Southeast Asia, Middle East, Europe, Americas, Latin America, etc.
• Global prefix generation: Based on an operator code database, regularly maintained and updated. Generated numbers can be directly submitted to filtering tasks.
• Custom prefix CSV import: If you have known valid number prefixes (e.g., first N digits extracted from industry data), you can upload a CSV to generate numbers by rules, significantly improving subsequent filtering hit rates.

All generation operations are completely free. Generated numbers can be directly submitted to filtering tasks, with charges deducted based on the number of numbers detected (generation itself does not deduct balance).

Number Prefix Generation Strategy: How Does the “Hit Rate” of Random Generation Affect Subsequent Filtering Costs?

Filtering costs depend on the actual number of numbers detected. If randomly generated numbers contain many non-existent or deactivated numbers, they still consume balance during filtering (because the system needs to send signaling or protocol requests), leading to wasteful spending. Therefore, prefix quality directly determines real costs.

thdata’s Prefix Strategy

thdata’s prefixes come from public operator databases; the specific update cycle is not disclosed. If users cannot upload custom prefixes, they rely entirely on the platform’s built-in prefixes, which may generate many invalid numbers. It is recommended to prioritize prefixes with clear operator identification and do small-scale testing before mass generation.

KK-DATA’s Prefix Strategy

KK-DATA uses a two-layer strategy to reduce wasteful consumption:

1. Built-in prefixes: Based on a global operator code database, continuously maintained and updated, trying to eliminate discarded prefixes.
2. Custom import: Allows users to upload a CSV of known valid prefixes; the system generates number combinations based on the prefixes. For example, if you extract a batch of numbers starting with “852-6” from closed deal customer data, importing them generates all “852-6xxxxxxx” numbers, with a much higher hit rate than random generation.

Additionally, after generation, numbers can directly enter filtering tasks. Charges are deducted from the balance only after the task completes, and tasks cannot be submitted if the balance is insufficient, avoiding unnecessary spending. It is recommended to check the unit prices for different detection types in the console.

Free Generation vs. Per-Number Filtering: How Does the Billing Model Affect Total Costs?

Item	thdata	KK-DATA
Number generation fee	Unclear (possibly per-number or per-task)	Completely free
Filtering billing method	Per-task or per-number (to be verified)	Per-number, deducted after task completion
Subscription plan	Possibly available	No subscription plans, pure pay-as-you-go
Top-up method	Unclear	USDT (TRC20) anonymous top-up, minimum ~50 USDT
Cost estimation	Uncertain	Estimated cost shown before submitting task

Key difference: If thdata also charges for generation, users would have to pay for all generated numbers, even if subsequent filtering may fail. KK-DATA separates generation and filtering into two independent steps: generation is free, and filtering is charged per successfully detected number. This means you can generate numbers and only pay to validate effective ones, reducing wasted costs.

For example, you generate 100,000 Thai numbers, of which only 30% might be valid. Under KK-DATA’s model, you only pay for filtering 30,000 numbers; if thdata charges per number for generation, you would pay for all 100,000 numbers plus filtering fees, leading to higher costs.

Data Deduplication and Export Efficiency: Practical Features to Avoid Duplicate Charges

For teams doing long-term batch filtering, duplicate numbers are the biggest hidden cost. Two tasks may contain the same number; if the platform does not automatically deduplicate, the same number could be charged multiple times.

• thdata: Whether it has built-in deduplication functionality should be verified by yourself. If not, users need to deduplicate manually using Excel or scripts after export.
• KK-DATA: Built-in data deduplication repository. All task numbers are automatically compared against historical numbers when uploaded; numbers already detected are not counted in the current task, avoiding duplicate charges. Supports CSV/TXT multi-format export and can merge results from multiple filtering tasks.

In terms of export efficiency, KK-DATA supports batch export of filtering results (activated, active, gender tags, etc.) without needing to copy each one.

Platform Security and Fraud Prevention Reminder: The Necessity of Official Customer Service Verification

In recent years, fraud incidents targeting users of overseas tools have become frequent, with fake customer service and phishing links appearing. KK-DATA provides a dedicated fraud prevention query page on its official website, where users can verify the authenticity of the official Telegram account (only official customer service: @kkdata_cc). Additionally, the official channel @kkdata_channel publishes security announcements.

Whether thdata has similar mechanisms is not publicly disclosed. It is recommended that users of any platform always contact customer service through official channels (official domain, official group) and not trust unofficial private messages.

Selection Recommendations: When to Choose thdata and When to Choose KK-DATA?

Scenarios for choosing thdata:

• You consistently use numbers from only a few countries (e.g., Indonesia, Vietnam), and thdata’s prefix quality in those countries is high.
• You are already familiar with thdata’s workflow, and the cost of switching your team is high.
• You need integration with thdata’s other ecosystem (e.g., their social media services).

Scenarios for choosing KK-DATA:

• Need large-scale, multi-country numbers: Free generation for 240+ countries, combined with custom CSV import, to quickly build a number pool.
• Budget-sensitive, want pay-as-you-go: No subscription, free generation, per-number filtering charges, deduction only after task completion.
• Value deduplication and efficiency: Built-in deduplication repository reduces duplicate charges; supports tgid export, gender recognition, and other fine-grained operational features.
• Require anonymous payment: USDT (TRC20) top-up, minimal amount to start.

We recommend first generating a small batch of numbers for free on both platforms, test filtering quality, compare hit rates and actual costs, then make a decision.
