Nomorobo actively maintains a very large database of active robocallers, but robocallers create new numbers all the time.
The Nomorobo detection system often detects these numbers just a few minutes after they become active, however by this point it is possible they have already called several thousand numbers, so it sounds like your number happens to be one of the early unfortunate few.
To assist in early detection, we would very much appreciate reporting any new numbers. We review every single one of these reports, and regularly add the reported numbers to our global database.
If you do get a robocall, please report it here.
Note: If you got a call from an "Unavailable" Robocall, or a Robocall without a number, or a Robocall with too many digits, please fill the form out with all zeros, and then in the "Anything Else" section, write exactly what the caller id said.
