CreationDate estimates Telegram account creation dates based on a long-term collected dataset of Telegram private user accounts with known creation periods.
The estimation uses linear interpolation between verified UserID anchor points.
The dataset was collected and refined over several years and includes only private user accounts (no bots, groups, or channels).
Typical accuracy:
- Year accuracy: very high
- Month accuracy: very high
- Granularity: usually within weeks
- Older accounts: may vary slightly more, but still reliable on a monthly level
In most cases, the estimated creation date closely reflects the real account creation period.
Telegram does not publicly expose exact account creation dates.
While UserIDs are assigned sequentially, the allocation rate is not perfectly constant over time.
Factors that can affect precision:
- Variations in Telegram user growth rate
- Internal Telegram ID allocation behavior
- Large-scale onboarding waves
- Only private user accounts are supported
- Bot accounts are intentionally excluded
- Groups and channels are not supported
(IDs starting with-100...are invalid) - Negative or non-user UserIDs are rejected
This project provides high-quality estimates, not official data.
Dates should not be treated as legally or technically authoritative.
Use this information responsibly.
