This number called me three times in one day without leaving a voicemail. Caller ID was out of Princeton NJ. I called them back. The man on the other end was difficult to understand, stated he is an investigator at the department of internal revenue, and asked me if I had received any letters. I said no and he said that there was an issue with my taxes from 2010 to 2015 and whether I used an agency to file or completed my taxes independently. I asked him which year there was an issue, as taxes are filed on a yearly basis and he just restated his previous question and stated that I owe over $5,000. I told him I have copies of my taxes, that there has never been an issue in the past, and never received a letter in the mail. He went off saying a few regulations (no idea if real) and that I have two options; I could setting in court with lawyers or provide the money and stay out of court. Then I asked him where they sent me the letter. He responded with 230 (some street name I could not understand) court. I asked him the state, he said Parkson City. Once again, I asked him the state and he returned with the same street address and city without a state (seemingly contriving a situation in which I disclose my address). Finally, I asked, "what state?" and he said Oregon. I told him that I have never lived in Oregon and have never even been to Oregon (truthfully). The man said "sorry" and quickly hung up!

Thank you everyone who has posted and hopefully these people get caught soon!
