Got the same kind of call but they called from 720 area code and told me to call number in 206 area code. 3rd call today from someone pretending to be from irs. Previous they actually called from an 800 that is part of irs but it's also scam. Told me to call back to 571 area code. Beware they're all scams.
Got the same robo-call from them. "We tried to reach you. This is a final call...". They don´t leave any probe in their message that they´re addressing you. Scam
