Received another call from this number, this time they left a message, I verified the information in the message by searching the number they gave me to call back on found it listed as a customer service number on an official website. I called them back and can confirm that it is legit. The last several messages here confirm that the number is legit, for some reason they sometimes don't leave messages and probably are not that efficient which makes people think it is a scam.

Received a call to my number, no message left. Tried calling back and there is a message stating it is a "nonworking number." I'm guessing it is not legit because they would have left a message if it was.

it is legit! when i called back it said i was calling a non working # so you should always call your credit card co # on the back of your card. It was the fraud dept calling about recent charges on my acct that I did make.. they are just looking after you...

Someone called me from this number from my current bank, Bank of America. I know this is legit, because I had used online bill pay and the check hadn't arrived yet. I had opened a case the day before, and they knew the payees and the situation regarding my check. I've never known a scammer to leave a message, either. This woman did.

I saw someone else post about online billpay on here, so maybe this is the company that banks use to follow up on billpay matters.  

This number is from FiServ EFT, and is in all likelihood your bank's debit card processor and fraud monitoring service, so yes, it's legitimate, but if you are unsure, contact your bank instead.  A customer service rep or someone at your bank should be able to verify the suspicious information for you just the same and contact FiServ on your behalf.

Some information I left out of my previous post. I received this call on a new cell phone I had just bought. Only 3 people know this number. None of the banks and credit card companies know this number. Although this might be a legit number from a legit company, this number can also be spoofed by scammers. So, if you do get a call from this number, do not give any personal information. If they are a legit company, they already have all your information. Once they tell you what bank or card is being used, call that bank or cards number, listed on back of the card or on your bank statement and verify that they are reporting a bougus charge.

This is a scam. Repeat, this is a scam. If this was a real bank and you did not answer the call, would they not leave a message to call them back? I have had real calls from banks regarding people trying to use one of my credit cards. First, their caller ID showed up. Second, they left a message to call them back. Third, when I called them back, I got through to them and did not get a message saying the number was invalid.

I also got an email from the bank asking me to verify the charge.

Despite what some posters have said, this is a scam.

First of all, I have done ALL the detective work on this number.
I called back the number and an outgoing message said:  this is not a working number.  If you received a voicemail message, call the number in that voicemail.

RED FLAG  NUMBER ONE:  If it is not a working number, then no one would have been calling ME from THAT number, for starters.  
RED FLAG NUMBER TWO:  If it is ot a working number, the phone company and an automated system will tell you that, NOT a prerecorded voicemail directly you to "call the number that was left for you on voicemail".
RED FLAG NUMBER THREE:  The message was extensive.  it gave the name of the caller (Mike from Bank of America online bill pay), it gave a credible message: Brian Hart has a charge to the account of $1064.76 related to you, Case #55192599. Please call 855-739-0856.  (You have to be VERY SMART to catch this - no bank calls a potential perpetrator about fraud on their own customer's account.)
RED FLAG NUMBER FOUR:  I called the 855 number and a woman claiming to be "Amber" answered.  She insisted on my name:  NO THANK YOU - I don't give out my name to anyone.  "What's the case number."  I didn't give it at first, but asked her who she was, what company she worked for (BofA), what department (Merchant Support).  
RED FLAG NUMBER FIVE:  I said:  so what do you want?  and she said:  well you called ME.  and I said: No, YOU called ME and I called you guys back, now what do you want?  So she starts down this winding trail of "we have to protect our customers blahblahblah.  And I said:  WHOA!  If I am your customer, go ahead and protect me.  If someone else is your customer that you are trying to protect, or so you say, WHY ARE YOU CALLING ME?  I also told her I thought she was an unmitigated fraud, had no credibility, was a crooked as the day is long, and will look really good in an orange jumpsuit, hopefully.

I reported all of this to Bank of America, as that was the supposed Bank they were calling from.
ALL SCAMS PEOPLE.  ALL ALL ALL SCAMS.

I received a call from this number a few moments ago and let it go to voicemail.  The person didn't leave a message.  I came here, read the posts.  Then checked my Bank Account and saw nothing unusual.  I called the number - get this - there is an outgoing message saying:  this is a nonworking number!  hahaha  How stupid do these people thing we are.  It IS a working number and I just reached your voicemail, dumbcluck.  The outgoing message further says to "call the number left for you on your voicemail".  However, as I said, t here was no message left.  I sense this is straight up fraud.  I've had these types of calls before.

The call is legit - it is the fraud detection center.  My credit union has an automatic block on international attempts to collect on my debit card.  I made an international order - the block was removed - all is well.  Merry Christmas to my hubby!

This was a call from my bank regarding an inquiry I made about an on-line bill pay that was not received by the payee.  They called my cell phone and then called my work number.  They did NOT ask me for any of my personal information -

Never, ever give out personal information to an incoming call UNLESS you can verify or you are familiar with the number calling you.  Never click on a link for a bank or credit card - always type in the web address manually.  

I received a call from this number.  It was from Bank of America and was legitimate.  I service a loan that incurred a late payment because BoA was not able to send the electronic payment on time.

totally legit. i used my cc for a transaction outside the usa and i guess that set off some bells because the cc issuer wanted to confirm the charge. i approved it over the phone, they didn't ask me anything personal, no ss# or anything, just my address.

(800) 279-2674 is a number used by a company called Fiserv. They are a contract financial services company that is used by a number of banks. When someone calls from this number the say they are from your bank. If the said Fiserv you wouldn't know who that was and a lengthy explanation should have to follow with half of you thinking it was a scam.

How do I know this, I do because I have been in several lengthly conversations with their reps about a problem with on line Bill Pay provided by my bank which also included a 3 way conference call between me, my bank and them. When I call them, I use a different number, when they call me, it is always this one.

So. if someone calls from this number just tell them you want to verify who they are for security purposes, ask them who they get their paycheck from and ask for a call back number that is in the phonebook or switchboard number with an extension. Then look up
the company and call them to verify the number.

The reason so many banks have the same number is that they all contract with these guys.

So, trust but verify next time.

This is indeed a scam.  I work for the bank they were claiming to call from. Idiots.  Don't answer unknown calls.  Google the number, then find a real number through your financial institution's website to verify the call.

Folks, don't trust the "IT'S A SCAM," OR the "IT'S LEGIT" posts. Do yourselves a favor, ignore all the spam and comments, do NOT give any info over the phone, and ALWAYS:

CALL THE NUMBER ON THE BACK OF YOUR CARD.

Always. Call. The. Number. On. Your. Card.   Problem solved.

BE AWARE IT IS FRAUD!!!! CALLED MY BANK AND THEY DO NOT DO THIS!!!!

I also did verify this WAS FISERV calling on behalf of my bank. Yes you will be given a call back number that is slightly different than the number you are called from. I was called from 800-279-2674, and I was given a call back number of 800-262-2024. I then called my bank directly to verify and I was told FISERV monitors the accounts for many institutions, so they call on behalf of the financial institution.

This was a call from my bank, Patelco Credit Union, fraud prevention. Fraudulent charges had been attempted using my debit/visa card. Fortunately all were declined, my card is deactivated and a new card is being sent.

Received a call from this number, I didn't answer but they left a voicemail w/case number. No credit card information asked for at all. They verified the last couple of charges and they put a hold on my card but it was immediately lifted after verifying I did make those charges.

This is an absolute legit call. They called this evening to warn me of fraudulent charges on my debit card. By all means, return their phone call

I spoke with Keke was well, she was very helpful and only asked a few basic questions as you stated.

This number called me today (8-26-2013) and left me a voicemail, claiming to be fraud protection from my bank.  Skeptical, I Googled the number (and landed here).  Then I checked my bank account... There was a pending purchase for $369 at Walmart.com and several smaller purchases still pending, all of which are halfway across the country.  I called the number given in the voicemail and spoke with a representative who immediately put a block on my card and told me to call my bank.  I am really thankful they were able to catch this so quickly, especially considering this is an account I rarely use and may not have noticed the purchases for awhile. Thankfully everything is taken care of now and whoever the scumbag is that stole my information won't be getting whatever they tried to purchase!!!

Got the call today, they did leave a message it's bank of america.  My dad had sent a check to order something from my daughter, and i never received it.  They were calling to verify payment was sent, they would void that payment, and cut a new check

Got a call from this number, and haven't had any card for several months.

I got this call but did not answer.  Seeing that others said it is a company reporting illegitimate activity on my bank account, I looked at my account and saw my balance was the same.  However, I didn't look at the pending transactions.  When I tried to use my check card 2 hours later, it was declined.  Sure enough, my credit union said there were some charges that came in from Romania and though two got through (I need to dispute now), they blocked 3 others.  I have to get a new card.  My credit union said FiServe is indeed a LEGITIMATE company.

I was JUST called by this number saying they were from my banks the fraud department, googled who it was, which led me to here. Thank f*ck because after filling out the affidavit at my bank this morning when i found out that nearly $8,000 was fraudulently debited from my account, i would have normally assumed they were going to help. Instead i kept repeating that my bank had all of the info and declined to answer if i had a purchase at walmart. very weird, but they got the point and gave up. this is the company who stole money APPA VCB NEW YORK VA US POS

THIS WAS A LEGIT CALL. I got a missed call and voicemail from 800-279-2674. Said they were Fraud Prevention Department for Central Pacific Bank. Gave me a Case # to reference. I called, spoke to Keke, and she started to ask me questions. I work for a law firm and we deal with this crap all the time. She said I could verify with my bank and call her back. As I had her on the line, I pulled up my online banking, and WHOOO it did not look right!

So, all Keke needed from me was my name and address. I gave that to her, and she proceeded to run down the most recent 7 transactions on my card. The most recent TWO were from this morning, each for just over $500, and both in Florida. Needless to say, those were bogus, since I live in Hawaii. The other transactions were correct.

I was told that the card was cancelled, and those two transactions did NOT go through.

Keke didn't ask any other info, and did not have my account balance. She was very nice. THANK YOU TO FRAUD PREVENTION!!!!

This is legit. I let this call go to message because I didn't recognize the number. I made a payment on a credit card through Bank Of America online bill pay. The payment did not get posted to the credit card. I filed a claim and they researched my payment. They called me back (left a message at work) to say they have been working with the credit card company and will send me a message through BofA secure message center on what I need to do to get the credit processed.

Got a phone call on my cell around 8:15 am. I didn't answer it went to voicemail. When I tried to receive the message there was nothing on it. Checked my account on line and saw three charges were pending and I didn't authorize any of them, so called my bank, they said they would send me paperwork to reverse these charges if they go thru after they are now pending. My bank put hold on my acct. and are sending me a new card. Makes me made they get away with this action, no one is safe.
