Definitely fake, tried contacting me on a number that only receives texts and voicemails, no phone calls. This number would not have been on any of my tax forms.
Same type of call as reported above. Robocall from CID 57 0 69 52 68 87 - - gave this 202 386 6297 number as a call back to the IRS. 57 is the country code for Columbia. Scam.
