I am making a database in which my algorithm only accepts queries from users with telegram id length of 9.
user_id: 123456789;
length = user_id.length;
display(length);
OUTPUT: 9
Are there telegram user ids of length lesser than 9?
Can anybody suggest something, so that i can update my algorithm to length of that ids too.
You can refer to Contact section of API document.
it has at most 52 significant bits, so a 64-bit integer or double-precision float type are safe for storing this identifier.
There have no known limit of user ID, but I know there have some user have less than 9 digits ID.
For instance, @MarkusRa have 6-digits ID.
The maximum length I have seen is 9 digits, and starts with 6, it seems to increase by time, maybe it will have 10 digits soon
