<prompt> Human: About ten years ago, I received my first piece of mail addressed to Salvador LastName. My first name is Rob, not Salvador, but he and I apparently have the same last name. I marked it not at this address, return to sender and dropped it back in the box.Over the next year, mail arriving for Salvador became a regular thing. I finally opened one envelope out of curiosity. It was a notice from another states department of revenue, indicating several years of past-due child support. It might be worth mentioning that I have never had child support payments; my wife and I are the biological parents of all of our children, and we are raising them together.I called the number on the letter to tell them that they were sending these notices to the wrong address. They told me that Salvador had contacted them a little over a year prior to file a change of address, and the address he gave was mine.I do not have any relatives named Salvador, nor do I even know any person named Salvador, let alone one who shares my last name. As best I can figure, he picked my address out of the online white pages because we have the same last name.Over the years, every time we have moved even out of state, the mail for Salvador has followed us. I have tried working with the post office to block mail delivery for items addressed to Salvador, but this has never worked for more than about six months.Heres where I am becoming concerned about my personal credit: One of my recent, personal credit reports listed Salvador LastName as one of my additional names. I corrected this with TransUnion and it no longer appears on my report, but for the past two months, almost half of the mail that I now receive at my home address is from collections agencies, addressed to Salvador.As of yet, I have not seen any accounts on my credit report that do not belong to me, so I dont think its really an issue of identity theft, but the fact that Salvadors name showed up on my credit report really spooked me, and clearly a number of creditors now think they have located Salvador based on my credit report.In addition, all of those websites that try to sell you information reports on specific people such as Intelius have now linked me and Salvador to each other. So now, all of those shady collections agencies who try to contact your relatives to get in touch with you have now obtained my home number and cell number, and I have been getting calls asking, May I please speak with Salvador?On a scale of 1 to 10, how concerned should I be about this affecting my personal credit as opposed to just being an ongoing annoyance, and is there anything I can do about it?  <response>: Simply because Salvador hasnt opened credit accounts in your name doesnt mean he didnt steal your Identity. Check your Social Security statements online to see if your work history shows more history than it should. He could have in fact taken your SSN and is using that to be legal illegal immigrants will get SSNs from other people to become paper legal in that they can use bank accounts and get jobs and licenses.I would certainly speak to a lawyer about this.
