Just received a message from this number from "Tyler from the Official Notification Department? saying he had good news for me about a $50,000 sweepstakes I supposedly entered within the last 18 months. I'm glad I looked it up. Nothing but rubbish.

Some  of the common scams listed here, on 800notes, are  the "you won a prize" or "free grant" or "award" scams.
Those scams are described here:

(That site also has a link to Amazon's phone blocker devices and apps, as well as a page showing various government sites that accept complaints or warn about scams.)

I received the same exact call saying I won $50,000 from an entry i submitted. Call back a number, this is a scam. I did not call back nor do I answer calls from numbers I do not know. UGH  This was the second time I received the call.

Recieved a call from this number from "Bill" concerning my entry "sometime in the last 18 months" for their $50,000 cash prize, with "very good news". Provided the following number to call back: 1-855-5457-7296. I believe this is the second or third time I've gotten this call and the message sounds the exact same. Guessing its a recording. I've never answered and I've never called back. Things that seem too good to be true usually are. Who does this kind of crap?

no caller ID

I received a phone call from this number.  They tried to break the connection as soon as I answered.  I tried calling them back to tell them how rude that was.  The phone just rang and rang - no answer.

got a call saying congratulations on the $25,000 holiday entry i made at the beginning of this year.

did not make any kind of entry that I am aware of.
