The following table is a list of error codes used with individual income tax returns for 2008.
They will not make much since to you.
So let me interpret.
These two codes mean that something is not matching up. This can be name, ssn, or math errors.
Since you filed electronically, I doubt very seriously it is a math ERROR code.
I am sorry I can not tell you specifically what the errors mean in your case.
You can tell from the published chart, why you get different results each time you contact the IRS.
In your case it is most likely because of a mismatch of name, ssn , addresses, or another person claiming your dependents if any, or even a delay due to a tax offset for student loans, back child support, etc if this applies to you.
