I got calls from the same number 2022417290 2 times.
day1- he told me there is a legal case against me and they sent 3 reminders for a fraud case, then I asked the address he gave me some wrong address. I told him if he is really from IRS then he should have my correct address and the number he called me is never in my any returns that's a relatively new number got 4 months back, I asked him I need to verify his identity.he threatened me a cop will be in my door step in next 30mins, I said I will definitely welcome a COP then he hung up.

day2- again got the call and told and I asked him your number and call routing is traced and seems a call center out side of USA, he said calling from PAK and hung the call.

I called him from my cell at 6.41PM and he picked the call and said Jason from labor dept, I asked him working hours for him, he is saying its 24X7 and I told I got a call from this number though I didn't got any calls in my cell, he said we called you several times but I didn't responded, I told him you never called to this number but I am calling you , he hung up.
so please careful to all these frauds and never never disclose any identity over phone to anyone.
