Complete Guide to Exporting TGID from Telegram Registered Phone Numbers: How to Export TGID and Field Descriptions After Detection

In cross-border customer acquisition and community management scenarios, batch verification of whether phone numbers are registered Telegram users (i.e., “open numbers”) is a common preprocessing step. However, many teams stop at simply knowing “which numbers are usable” and overlook the more valuable long-term operation of exporting TGID. This article focuses on exporting TGID from Telegram open-number detection, explaining what TGID is, how to detect and export it, the meaning of each field, and downstream usage methods—helping you maximize the utility of a single detection run.

What is Telegram Open Number Detection? Why Export TGID?

The core of Telegram open-number detection is verifying which phone numbers in a batch are already registered on Telegram. Through detection, you get a clear “number–status” list: which numbers are active users, which are unregistered or invalid. This is crucial for precision targeting, bulk group invitations, private messaging, and other marketing activities.

However, simply knowing that a number is “open” is not enough. Many practitioners find that sending messages directly to a large number of open numbers may be restricted—Telegram imposes rate limits and privacy protection policies on direct API calls using phone numbers, and numbers may change over time. In such cases, TGID (Telegram User ID) becomes a more stable alternative identifier.

What is TGID? How Does It Differ from a Phone Number?

TGID (Telegram ID) is a unique numerical identifier assigned to each user by Telegram, similar to a “digital ID number.” It does not change when the user changes their phone number. Here is a core comparison between TGID and phone number:

Dimension	Phone Number	TGID
Privacy	Directly linked to user privacy; users can set “only searchable by number”	Only appears at the API level; invisible to regular users
Stability	Numbers may become invalid due to account cancellation or number change	Once obtained, remains valid long-term unless the account is deleted
API integration convenience	Some endpoints operate only via phone number and are subject to rate limits	Telegram Bot API accepts TGID as user_id in most methods
Downstream extensibility	One‑way reach (number must be valid)	Can be used with bots for actions like banning, muting, private messaging, etc.

Prerequisite for Obtaining TGID: The Number Must First Pass “Open” Detection

This is critical: Only numbers that are already registered on Telegram (i.e., “open”) can yield a valid TGID. Numbers that are unregistered or invalid will have a status of “not open” and the TGID field will be empty or zero. Therefore, before exporting TGID, you need to complete Telegram registration detection and only proceed with numbers that have the “open” status.

Mapping Relationship Between TGID and Phone Number (Based on KK-DATA’s Detection Logic)

When KK-DATA detects whether a number is a registered Telegram user, it also attempts to map the corresponding TGID. After detection, each record contains the phone number, detection status, and TGID field. This mapping is one‑way: you submit numbers → the platform detects → returns TGIDs; you cannot reverse‑lookup a phone number from a TGID. Therefore, it is recommended to keep both the phone number and TGID columns when exporting to avoid data loss.

How to Perform Telegram Open Number Detection and Export TGID on KK-DATA?

Using KK-DATA as an example, the workflow is very straightforward. Steps are explained below.

Step 1: Prepare the Number File and Task Configuration

1. Upload the number list: Organize the phone numbers to be tested into a TXT or CSV file (one number per line, including the international country code, e.g., 8613812345678).
2. Enter the console: Open the Application Console and select “Create Screening Task”.
3. Select the detection platform: In the detection module, choose “Telegram” and set the detection type to “Telegram Open Number” (you can also check “Activity” or “Gender Detection” to obtain additional fields; this does not affect TGID export).
4. Configure export fields: On the task configuration page, you can pre‑select the fields to export. Make sure to check the “TGID” field. If not checked, the default export may include only the number and status.

Step 2: Estimate Costs and Check Balance Before Submitting the Task

Before submission, the platform will display an estimated cost (calculated as detection quantity × unit price). All detections can only be submitted when the balance is sufficient. If the balance is insufficient, you need to top up via USDT. For specific unit prices, please refer to the official pricing page. Anonymous recharge via USDT (TRC20) is supported, with a minimum of approximately 50 USDT.

Step 3: Export the CSV File Containing TGID After Task Completion

After the task is completed, find the record on the task list page and click the “Export” button. In the export pop‑up, you can custom‑select the fields to export. Ensure “TGID” is checked. The default format is CSV or TXT; CSV is recommended for subsequent reading.

Export Field Description: What Does Each Column Represent in the CSV/TXT File?

Typical columns in the exported CSV/TXT file include:

Core Fields: Phone Number, Detection Status, TGID

Field Name	Data Type	Description
phone	String (all digits, includes country code)	The original phone number you submitted, e.g., 8613812345678
status	String	Detection result: open (registered) / invalid / closed (not registered), etc.
tgid	Number (pure integer)	Telegram user ID; valid only when status=open. May be empty or 0 if not detected.

Auxiliary Fields: Registration Time, Gender Recognition (if the task includes activity or gender detection)

If your task also checked “Activity” or “Gender Detection,” the export file will additionally include the following columns:

• register_time: Account registration time (Unix timestamp or readable date format).
• active_days: Number of days since last activity (e.g., 7 means active within the last 7 days).
• gender: Gender output by avatar‑based AI model (male/female/unknown).

Note: Gender recognition is based on an avatar AI model; accuracy is not 100% and should be used only as auxiliary reference.

How to Use the Exported TGID for Downstream Integration? (Automated Group Invitations, Private Messaging, Data Cleaning)

Once you have the CSV with TGIDs, you can do many meaningful things:

Scenario 1: Bulk Invite Users to Groups (Deduplicate or Invite Based on TGID)

Suppose you operate a Telegram community and need to send invitation links to a batch of open users. The fastest approach is: use the Bot API’s createChatInviteLink to generate one‑time links, then send private messages to each TGID via the API (using the sendMessage method). Note: sending too many private messages to inactive accounts may trigger rate limiting. It is advisable to first use KK-DATA’s “Activity Detection” to filter recently active users before performing operations.

Scenario 2: Integrate TGID with CRM/SCRM Systems for User Segmentation

Import TGIDs (as unique identifiers) into a CRM system to enable customer recognition, retention analysis, etc. For example, you can mark which users are already “existing fans” who have joined other groups, and which are completely new. Combined with gender and activity fields, you can implement differentiated marketing strategies (e.g., push Product A to male users and Product B to female users).

Common Errors and Pitfall Avoidance During TGID Export

1. Incorrect number format leading to detection failure: Numbers must include the full international country code (e.g., 8613812345678, not 13812345678). Otherwise, they may be recognized as invalid and cannot yield a TGID.
2. Export without checking the TGID field: A very common oversight. Before submitting the task or inside the export pop‑up, manually check the “TGID” field. If you forget, you can reopen the completed task and re‑export with the field checked.
3. Mistakenly using TGIDs from cancelled accounts: Some numbers might have been detected as “open” but the user later deleted their account. In such cases, the exported TGID may still exist but will be invalid for API calls (e.g., returning “user not found”). After export, first filter records where the TGID field is not empty and not 0, then test on a small batch (e.g., send 5 messages to verify) before large‑scale use.
4. TGID cannot be used manually: TGID is a string of numbers; you cannot search for the corresponding user via Telegram’s search bar (unless the user has set a public ID). It is only suitable for system‑to‑system integration via the Bot API.

Frequently Asked Questions (FAQ)

Q: Can TGID always be exported after “Telegram Open” detection?

A: Not necessarily. Only for detection results with the status “open” (i.e., the number is registered on Telegram) will the TGID field contain a valid user ID. For numbers that are not open, the field will be empty or “0”. It is recommended to filter for rows where status=open before exporting.

Q: Can the CSV file with exported TGIDs be directly used with the Telegram Bot API?

A: Yes. The exported TGID field is a pure number (e.g., 123456789), which can be directly used as the user_id in relevant Telegram Bot API methods (such as getChatMember, banChatMember, etc.). Note: if a number detected as “open” has an empty TGID, it may be due to an abnormal number or the platform failing to retrieve it; a re‑detection may be needed.

Q: What is the maximum number of TGIDs that can be exported in a single task?

A: KK-DATA supports up to approximately 1 million number detections per single task. The export file size is limited by the actual number of open accounts. For large tasks, it is recommended to export in batches or use the platform’s built‑in deduplication repository to reduce duplicates.

Q: Are the TGID field and phone number field exported together?

A: Yes. Both default and custom exports can include both the phone number and TGID columns, facilitating upstream/downstream data mapping. It is recommended to keep the phone number as a backup correlation key.

Q: Can a phone number be reverse‑looked up from an exported TGID?

A: No. Telegram does not provide a reverse mapping from TGID to phone number. KK-DATA only obtains the TGID based on the numbers you submit during detection. After export, you cannot retrieve the original number from the TGID. We recommend backing up the correspondence between numbers and TGIDs in advance.
