I've been a CoreStates/First Union/Wachovia/Wells Farg customer for over 25 years. I used to get calls from this number whenever I was driving very long distances on vacation or making large purchases in rapid succession around Christmastime. They have unlocked my card for me in the past once I confirmed purchases.
For the people reporting they don't have a card with them, I strongly suggest that you check for identity theft. Someone may have opened a card in your name. Just because you didn't open a card doesn't mean it's impossible there's a card out there based on your name and identity. Take this seriously.
I only chose "Event Reminder" below because the "Event" was suspicious activity on my card.
Got a call from this number and answered. They said it was Wells Fargo about a purchase and whether it was me. Sounded questionable based on the other posts here. I just ended the call politely and called Wells Fargo myself. The call was legit. They were worried about fraud and trying to protect my card.
Same here, someone got my card numbers and were buying stuff. Wells Fargo suspected fraud and contacted me to ask if I still have my card. They suspended my card and re-issued a new one. They also took the fraud charges off my account. It is a legit call and I am glad I answered.
This was a caller from Wells Fargo fraud department. It was legitimate. I called Wells Fargo back on their 800 number to verify and they confirmed that someone had called me and they were even able to verify the content of the conversation.
