Detection signals
What Telegram Days Checker detects
Telegram Days Checker confirms registration and returns how many days since the account was last online, without messaging or storing the number. Every row comes back with structured activity signals ready to prioritise live users over dormant ones.
Registration status
Confirms whether the phone number is registered on Telegram (yes or no).
Days since last online
Returns how many days have passed since the account was last active on Telegram, so you can prioritise live users over dormant ones.
Account identifiers and Premium
Returns available username or UID and Telegram Premium status alongside last-online time and active days.
Passive, no contact
Reads registration and activity signals only. The account holder is never messaged, logged in to, or notified.

FAQ
Telegram Days Checker questions
Can I check phone numbers against Telegram Days in bulk? +
Yes. Upload a CSV of up to hundreds of thousands of numbers or call the REST API, then download a result file with registration status and days since last online for every number. You are billed only for successful checks.
Does the check message or notify the person? +
No. The check is passive and reads registration and activity signals only. Nothing is sent to the number, and the account holder is never contacted or notified.
What's the difference between this and Telegram Checker or Age & Gender Checker? +
Telegram Checker only confirms registration (yes/no). Telegram Days Checker adds how many days since the account was last online. For estimated age, gender, and avatar analysis, use Telegram Age & Gender Checker.
What does N/A mean for days since last online? +
N/A appears when the number is not registered on Telegram or the last-online signal isn't available for that account.
