Three call from this number today.  Did not answer because I don't recognize number.  After reading these posts glad that I didn't answer.  ...  Received an Amazon delivery today, but it was a gift.  Not sure if there was any connection to that.

Got a call, left a message, got 2 more calls in a row immediately after I didn't answer. Said they were with amazon and verifying a purchase. I called back - they were requesting information to 'verify' a purchase. This information would not be asked for by Amazon. They even asked me if I had an Amazon account. Didn't give them any info, immediately hung up. They called right back - I blocked the number.
Checked my credit card immediately. Two fraudulent charges pending from yesterday. One test charge for $1 for a Mexico based cab company, and an unknown $95 charge through Amazon marketplace payments. Called my credit card fraud department right away.

Just got called by this number .. I did not answer . I called Amazon they stated it was not Amazon then instructed me to change my password . They said they would monitor my account .. This is an ABSOLUTE scam .. DO NOT answer when called by this number (206)508-4014 !! Check your credit card transactions daily ..

Got a call from this number today. Identified on the phone as Amazon. Wife took the call as I was not home. The Amazon account is in my name with no reference to her. Caller asked for me but I wasn't home so she proceeded to quiz my wife for information. Wanted her to verify the last numbers of the credit card which she refused to do.Not being the cardholder she shouldn't even be asked that. The caller got into a bit of panic and insisited that this had to be done now. My wife stood her ground and said they would have to call back when I returned home. Theyu wouild not give a call back number.
When I returned home I immediately Googled the phone number and foind this site. I also checked my credit card info online and all appeared to be correct. As a precaution I called the credit card company to verify if any purchases had been attempted. They said not but as a precaution I cancelled the card and asked for a new one. I then contacted Amazon and was told that no fraudulent attempts had been made to purchase on my account. I also asked him to verify the phone number and was advised that the number is NOT an Amazon number. Interesting thing is that the scammer number was identified as Amazon on my phone but when Amazon actually called me the ID only said Washington which is typical of calls from the USA to Canada.
So after doing all that the scammer did actually call back. Tried the same trick with me. Wanted me to verify and she mentioned a @hotmail email address which I don't have and she said the last two numbers of my credit card were 60 and they are not. When I asked he to repeat the info she refused. They talk very fast and are quick with the reply. Very slick. I told her she was going to hell for stealing and hung up.
There seems to be a bit of conflicting information in this thread with some saying the number is legit. I am convinced it isn't and would urge you to take precautions to avoid being scammed by these bottom dwellers. Amazon told me that they do not make such calls.

Sorry about the typos in my post.
