Telegram Active Number Compliance Guide: Data Use Boundaries and Privacy Considerations for Overseas Marketing in 2025

As Telegram’s user base continues to grow in overseas markets, many cross-border marketing teams rely on TG as a core customer acquisition channel. However, by 2025, platform algorithms and privacy regulations are tightening—bulk DMs, group channel promotion, number scraping, and similar activities face higher account banning risks than ever before. In this environment, active number compliance has become the bottom line for sustainable customer acquisition. This article helps you build a compliant number screening and marketing system across three dimensions—data use boundaries, privacy considerations, and practical steps—while using professional tools like KK-DATA to minimize compliance costs.

Why TG Marketing Needs to Focus on “Active Number Compliance”?

Telegram official has upgraded its anti-spam mechanisms multiple times between 2024–2025: introducing “rate limiting + behavior detection” for bulk DMs, and flagging numbers that frequently reach non‑contacts as suspicious. If you directly use numbers collected from public channels or unauthorized numbers for group broadcasts or DMs, your account risks at least a temporary ban, or worse, a permanent ban and the loss of your entire customer base.

More importantly, regulations like the EU GDPR and China’s Personal Information Protection Law (PIPL) impose clear requirements on the processing of behavioral data such as “user active status.” Active data does not equal marketing consent. Using active numbers obtained from screening for promotion without user consent violates both platform rules and may lead to legal action. Compliance is no longer just a slogan—it’s a necessary measure to ensure account safety and reduce complaint rates.

Common “Data Use Boundary” Pitfalls in TG Marketing

Pitfall 1: Equating “Number Active” with “Consent to Receive Promotion”

This is the most common misconception. When a Telegram user activates their account, their “active” status only means they have recently interacted on the platform (e.g., sent messages, viewed channels)—it does not mean they agree to receive third‑party marketing messages. European data protection authorities have clearly stated: using behavioral data for direct marketing requires explicit and active opt‑in. China’s PIPL similarly requires a clear purpose and notice when processing personal information. Therefore, active numbers are only a screening pool, not a marketing license.

Pitfall 2: Reusing Active Data Unlimitedly Across Multiple Purposes

Many teams reuse the same batch of screening results for multiple independent marketing campaigns: first a cold mass DM, then a few weeks later for community invitations, or even resell them to partners. This “one number for many uses” easily exceeds the user’s initial reasonable expectations. The compliant approach is: screen once, use once, discard after use. If reuse is necessary, reassess the purpose of data use, obtain new user consent, or anonymize phone numbers (e.g., hide the last four digits) to reduce identifiability.

Pitfall 3: Failing to Protect Privacy Data (e.g., tgid) During Screening

Screening platforms typically return phone numbers, tgid, activity tags, etc. tgid is Telegram’s unique user identifier—when combined with a phone number, it directly identifies a specific individual. If exported, transmitted, or stored without encryption, a leak could constitute a data breach and trigger regulatory penalties. We recommend immediately hashing or truncating tgid after export, keeping only necessary fields, and setting automatic deletion policies (e.g., 30 days).

Compliance Step 1: Correctly Identify Telegram Active Numbers

Registration Detection vs. Activity Detection: What’s the Difference?

• Registration detection: Only verifies whether a number has ever registered a Telegram account (i.e., “Telegram registered”). It does not reflect recent usage. Many dormant or abandoned numbers remain in a registered state.
• Activity detection: Goes one step further by checking if the user has shown activity (sent messages, gone online, etc.) within a specified past time window (e.g., 7 days, 15 days, 30 days). This parameter is closer to “real users who can actually be reached.”

Compliance significance: Using only “registration detection” to screen numbers carries lower risk but also lower marketing value. When using “activity detection,” you must mark the collection purpose in the data source and ensure the subsequent sending behavior meets user expectations. For example, if you screen users active in the last 30 days, you can say in your DM “Based on your recent activity on Telegram, we recommend…” but you still need to obtain prior consent to receive promotions.

Gender Recognition and User Profiling: Ethical and Legal Boundaries

Some screening platforms (e.g., KK-DATA) offer gender recognition via avatar analysis. Such user profiling can be used for personalized messaging, but note:

• You must not engage in discriminatory pricing or service discrimination based on gender, age, or other sensitive information.
• Under GDPR, processing biometric data or data that can infer gender qualifies as high‑risk processing and requires stricter consent.
• If your use case is purely product recommendation (not identity recognition), we recommend treating gender as a non‑mandatory option and explaining its use in your privacy policy.

Four‑Step Compliance Process for TG Marketing: From Screening to Sending

Step 1: Before Screening — Define Data Purpose and Record It

Before each screening task, create a data processing record containing:

• Data source (public channels / user submissions / third‑party API)
• Screening purpose (e.g., “Send activity updates to TG users active within 7 days”)
• Screening parameters (platform, country, activity window)
• Expected storage duration (recommend no more than 30 days)

This step serves as evidence of your compliance awareness during an audit or regulatory inquiry.

Step 2: During Screening — Use Minimum Necessary Parameters

When configuring a screening task, only check the detection types you truly need. For example:

• If you only need to know if a user has been active recently, select only “TG valid” + “TG active (30 days)”; do not additionally check “Gender recognition” or “Export tgid.”
• This minimizes collection of unnecessary personal data, reducing compliance risk. In the KK-DATA Console, you can freely choose detection items on demand.

Step 3: After Export — Data Anonymization and Short‑Term Storage

Apply two de‑identification steps after export:

1. Partially mask phone numbers: e.g., show first three and last four digits, replace the middle with asterisks.
2. Hash tgid: Use SHA‑256 to digest tgid; do not retain the original ID. At the same time, set up automatic deletion: configure scheduled cleanup (e.g., 30 days) on both server and local files. If longer retention is needed, you must obtain explicit user consent or meet another lawful basis.

Step 4: Before Sending — Set Up Unsubscribe and Complaint Handling

At the very beginning of each DM, clearly state the source, and at the end provide a one‑click unsubscribe link or a reply keyword (e.g., “unsubscribe”). Telegram does not support web‑based unsubscribe; you can handle unsubscribe commands via a bot. Also, establish a complaint response process: if a user reports you to Telegram official, you must stop sending to that user and delete related data within 48 hours.

Privacy Considerations: Key Regulations When Using Screening Tools

Data Minimization Principle

Both GDPR and China’s PIPL require processing only the minimum data necessary to achieve the purpose. In a screening scenario, if you only need to “verify whether a number is active,” the phone number itself is sufficient; you don’t need to collect tgid, avatar, nickname, etc. Platforms typically provide field selection during export—remove unnecessary columns before exporting.

User Right to Know and Right to Erasure

Data subjects (users) have the right to know that their phone numbers are being used for screening checks, and also have the right to request deletion of their data. Your operations team must establish a public contact channel (e.g., email or Telegram customer service) and respond to deletion requests within 30 days. If you use a third‑party screening platform (e.g., KK-DATA), you can state the data processor role in your privacy policy and ensure the platform can delete data (the platform does not retain user data beyond the task; only logs remain, which can be cleared via API).

Cross‑Border Data Transfer Requirements

• China PIPL: Personal information should not be transferred abroad, or if it must, it requires a security assessment. If you operate within China, personal data like phone numbers should not be transmitted to overseas servers. When using an overseas screening platform, ensure it meets relevant compliance requirements (e.g., having servers in China or having passed a cross‑border data assessment). KK-DATA provides global nodes for cross‑border teams; data storage location subject to confirmation with customer service.
• EU GDPR: Transfers of personal data to third countries require appropriate safeguards (e.g., Standard Contractual Clauses SCC). When using an overseas screening platform, we recommend signing a Data Processing Agreement (DPA).

Pitfall Avoidance Guide: Common TG Account Banning and Complaint Scenarios

Real scenarios many teams have fallen into:

1. Sending DMs to 500 unsaved numbers in one day → flagged as spam, account temporarily locked for 24 hours. Avoid: Space each message at least 10 seconds apart, and contact no more than 100 new people per day.
2. Using the same message template for all active users → many users mark as spam, numbers blacklisted. Avoid: Differentiate messages based on fields like gender, country to reduce repetition.
3. Reselling screening results to other companies → user information leaks cause mass complaints, Telegram bans all associated accounts. Avoid: Do not transfer data without anonymization.
4. Sending content containing malicious links or inducements to share → directly permanently banned by TG. Avoid: Ensure links point to legitimate websites that do not trigger phishing detection.
5. Long‑term storage of user tgid after screening for secondary analysis → violates GDPR if without consent. Avoid: Screen, use, then delete.

How to Use KK-DATA for Compliant Screening of Telegram Active Numbers

KK-DATA is a professional lead screening platform supporting Telegram validity check, activity detection (7/15/30 days), gender recognition, and tgid export. Its design inherently considers compliance needs:

• Auditable task records: Each task saves creation time, screening parameters, and execution results, making it easy for you to review and demonstrate compliance processes to regulators.
• Pay‑as‑you‑go: No subscription packages; you only pay for the numbers actually checked (real‑time prices available in the Console), avoiding idle tasks from hoarding balance.
• Deduplication pool: Automatically deduplicates across tasks, saving costs and reducing unnecessary number processing.
• Encrypted export and transmission: Exported CSV/TXT files are transmitted via HTTPS; we recommend you encrypt them locally after receipt.

The integration process is simple: log into the Console, select “Telegram Screening,” upload the numbers to be checked (randomly generated or custom), choose detection types, and submit the task. After completion, export and apply the de‑identification and deletion steps from the four‑step method above. For personalized consultation, contact customer service @kkdata_cc or refer to the official documentation.

Frequently Asked Questions

Q: If I screen “active” Telegram users and directly send them bulk DMs, is that illegal?
A: It is a high‑risk operation. Telegram’s Terms of Service prohibit bulk messaging without user consent. Even if the numbers pass activity detection, users have not authorized marketing content. We recommend using TG‑permitted broadcast methods (e.g., channels) or obtaining user opt‑in before sending. Otherwise, you risk account banning and penalties under data protection laws.

Q: Do I need prior user consent to use a screening tool to check number activity?
A: If numbers come from public channels (e.g., users left them on your website) and you have stated in your privacy policy “we will verify the number’s validity on social platforms,” it is generally acceptable. If numbers are purchased from a third party, you must ensure the purchase contract includes provisions for the data subject’s consent to transfer and process. Safe approach: declare the data processing purpose at the data source.

Q: Does KK-DATA’s activity detection trigger Telegram’s banned account mechanism?
A: No. KK-DATA uses non‑intrusive technology—it does not send messages or requests to the tested numbers, so it does not trigger Telegram’s banning. The platform only verifies account status via protocol layer, fully compliant. However, the subsequent marketing sending behavior must follow the compliance requirements described above.

Q: How can I set up automatic data deletion cycles?
A: Write scheduled cleanup tasks locally (e.g., cron job) or configure lifecycle policies in cloud storage. If you use KK-DATA’s task records, the platform does not retain user data long‑term; after a task completes, only logs remain (without phone numbers), which can be cleared at any time via customer service. We recommend completing your sending within 30 days after export and deleting the original files.

Q: If a user asks me to delete their data, what should I do?
A: Provide a clear contact channel (e.g., @kkdata_cc). After the user submits a deletion request, you must completely delete that user’s data from local storage and any backups within a reasonable period (usually 30 days). If the data has been incorporated into marketing lists, remove them simultaneously. We recommend establishing an automated response process and logging processing times to demonstrate compliance.
