This is a legit Wells Fargo number. It's their fraud protection line notifying you of unusual account activity. Please check your account to unauthorized charges. Instead of returning the call, I checked my account online and found my Platinum card was temporarily restricted due to unusual activity and someone had used use my credit card number to make purchases in a different state. I called Wells Fargo (1-800-642-4720) and the rep said there were several other changes that were attempted that they did not allow to go through and that they were manual entries, meaning they weren't using my physical card, just the card number. He connected me with their Fraud Protection department. They are crediting my account back the unauthorized charges and issuing me a new card. I have this as an emergency card so I rarely use, rarely check the activity. So grateful Wells Fargo caught this, declined the other transactions, froze my account and contacted me.
