The number checker is a tool for those who want to verify whether a phone number is registered on Telegram and obtain information about its owner. It’s enough to enter a number — and the system will show whether it’s registered, the user’s name, whether they have a username, when they were last online, and what they wrote in their bio.
Below is how everything is set up and works.
1. Use database – this is enabled if a check was already started and you need to continue from where it stopped. Just specify the path to the previously saved database, and the program will pick up the old data without starting from scratch.
If there is no database, paste a fresh list of numbers in the right field, and the checker will start working from a clean slate. The system automatically removes brackets, spaces, and dashes, converting numbers into readable format. However, if the number starts with "8" (instead of "7" for Russia), this correction must be made manually.
2. Request First name, Last name, bio – when this option is enabled, the checker additionally tries to extract the user’s name, surname, and profile bio if available.
3. Delay between requests – this sets the interval between request submissions. The optimal range is 5 to 10 seconds to avoid suspicion and prevent getting blocked.
4. Maximum timeout (FloodWait) – this sets a limit in seconds for how long the software will wait if Telegram temporarily blocks due to flooding. If the limit is exceeded — the account is removed from the task, if not — it waits the specified time and continues working.
5. Number of requests per account – to avoid errors and bans, it’s best not to make more than 15–20 checks from a single account per day. If the limit is exceeded, Telegram may not "see" even truly active numbers.
6. Select accounts – here you mark profiles from the active folder that will be used for checking. Only those marked as «Active» will work.
7. Gender determination – the checker will try to guess the user’s gender based on their first name. Gender is determined with 75% probability.
9. Streams сontrol – you can configure the number of parallel threads. For example, if 12 threads are selected, checking is launched simultaneously from 12 accounts. Once one finishes, the next one starts with a delay randomly selected from a set interval (for example, 30–45 seconds).
As a result, you receive a detailed file with results: first name, last name, username, bio (if any), activity status, and last seen time. All of this is saved and available for later analysis. If an account starts skipping numbers — that’s a reason to review the request frequency or increase the pauses. The main thing is to monitor the logs: «user found» means success, and «number not found» may indicate limit exceeded.
