What's happening here is that Treasury selects the bank that runs the lockbox operation -- currently, it's US Bank -- and then tells IRS what to tell its customers about mailing addresses.  The current contract doesn't expire until 2026, and there are hundreds of thousands of people who have been told to send checks to Cincinnati, so that address still works.  US Bank decided it would rather receive more mail at Charlotte and less at Cincinnati, and Treasury agreed with that.  Treasury told IRS to change its mailing instructions, but it's up to IRS to notify taxpayers.  Slipped through the cracks, during the reign of one of the seven commissioners this year.  But Cincinnati is still open and processing checks.  New vouchers should be printed with the Charlotte address.  Old ones don't need to be corrected.

And it's Armenia, not Albania
