@faray the rules for tax credits vary when it comes to ITIN.
taxpayers with ITIN are not eligible for EITC or stimulus / Recovery Rebate credit. it's not that it was issued after the deadline, it's simply the credit is not available for those with ITIN, regardless of when the ITIN was issued.
so yes, in these two cases having a valid ITIN has less tax benefits than having a valid SSN
