The social security number in question appeared as a dependent on another tax return for this same
year.

Whether the cause of this rejection is the result of a typo on another return or an attempt by another party to claim a dependent using your dependent's social security number, the IRS has security measures in place to ensure the accuracy of returns
submitted.

The IRS will question the dependency exemptions claimed by any other party using the wrong social security
number.

If you have verified this dependent's social security number and found no errors, unfortunately you need to file a paper
return.

Do not attach any information or documents that are not required with your return; if needed the IRS will contact you by mail for any supporting
documentation.
