You can't verify a 4883c letter online. You have to call them. Which is VERY near impossible since they won't EVER answer the phone. It would be SOOO much easier for us, for them to fix their online tool to accept the 4883c letter, at least until they get enough folks to answer their phones. Otherwise suspend sending the letters out!! Now, what are the odds the IRS will EVER see ALL these complaints AND actually fix the problem???!!!! NOT!
