This is a real number to their fraud number.  I called the card company using the number I found online, and they confirmed that I was, actually, showing suspicious activity.  I didn't even know I still had a Sears card - I'd forgotten I opened an account years ago.  Someone stole my social security number and tried to open an account.

The telephone is a valid for Sears' fraud department. If you call the telephone number on the back of your Sears credit card, that telephone number is for Citi who manages Sears credit card.  I did received a call from this telephone and call the telephone number on the back of my Sears credit card and was transferred to Sears' fraud department.  They asked me all my security questions and I asked if 800-669-8465 is one of there telephone numbers?  The rep confirmed that 800-669-8465 is one of their telephone numbers.  As always be careful about giving out info from telephone numbers that seem strange related to banking or credit cards and first start with the telephone number on back of your credit card or the telephone number listed on the official website.

I received a call from this number on 9/12/2013.  I called the number on the back of my Sears card, and discovered that the real Sears Credit Card did NOT call me.   Call the number on the back of your card, not the number they give you over the phone.

This is a valid number! This is a valid number! This is a valid number!
I was wrong when I thought it was a fraud(read my post above on 22 Jun 2013).  It actually was Sears.  We found out a week later that my wife's identity had been stolen and someone had opened a Sears card in her name, and this call was trying to verify the account.  I called Sears and asked about fraud on our existing joint account which is why they had no record of fraud.

I got a call last night, new my name and said to call 800-669-8465 and gave me a four digit reference number.  I called and it was a recording asking for my 16 digit account number.  Hung up and will call customer service.    My question is how can it be legit a few years ago and now it is not....

I received a call from this company also and they told me there was someone who tried to set up a credit account using my information and they had tried to make a purchase the same day with my account.  This simply didn't make sense. I've never had a Sears Mastercard and when I called the number back the first thing they asked was to look up my account using my Social Security number.  I did NOT give my SS# saying if they truly had an account of mine they could look it up by my phone number.  Of course, they could not find an account using my telephone number.  If you receive a call from this number, beware and do not give out any of your information.

We just received one of these calls, I called the number on Sears website and they had no record of activity on my account like the phone call stated  THIS NUMBER IS A FRAUD and is PHISHING for your account info!  DO NOT CALL!

I also recieved a call from this number claiming to be Sears.  I called Sears Credit Card Services and this is not one of thier numbers.  I will be reporting this to the police dept.  For you information you can report this online with your local police department.

It is a good number.  Had not used my card in a long time and made an on-line purchase.  Received a letter from Sears inquiring if the amount was authorized and to call 800-669-8465 anytime 24/7.  Operator had all my information concerning the purchase and my account information without me having too do any  prompting.  FYI: Customer Service number is: 800-669-8488.

I talked with my Father-n-law who also rec'd a letter with this number listed as a call back. He called and spoke with a gentleman, he said it sounded legit. Made me nervous as I heard of the news, never know who is scamming the elderly. Anyways; I am relieved to read that he was not scammed that this is legit. Thank you all for responding.

I, too, received the letter with the number 800-669-8465, saying my Sears acct had had "activity" that they would like to confirm... It looks pretty fake. I'll call Sears tomorrow.

Phone # 800-669-8465 is legit. I found out EXACTLY what John S found:
"Recieved letter in mail stating my account was compromised and to call this #.   Letter looked suspicious so I called the customer service # on my sears card instead of the one in the letter.  Sears confirmed there was a database compromise and they would issue me a new card."
In fact, the number on letter was only off the last 2 digits from the number on the card.

Call from 800-669-8465 that claims to be from Sears Credit Card department and would like to check on unauthorized charges.  I can't responed in any case as I destroyed the card and can't give them a number.  May be legitimate, I don't know.
