It is a person claiming to be from the IRS saying that there's a problem that needs to be taken care of immediately. They're fishing for your information so just hang up....scam scam scam
I just got this call today as well. I didn't answer the number but then they sent a text threatening to call local authorities if I didn't call them back.
I don't see how a California phone number can be listed as Washington DC. I don't see how these people are still getting away with this fraud??? These idiots did the same thing last year claiming to be the IRS office.
They're located in India and Pakistan. Hard core scammer/extortionists.
There's little the US can do and the local governments do less. Call blocker
is your best bet.
