They don't cross match W2/1099R EINS reported on a 1040 with names like they do taxpayers names and SSNs.

As long as an EIN is valid on a W2 or 1099R, it will go through electronically.

As long as the dollar amounts reported on the W2 or 1099R on the taxpayer return match up with the dollar amounts the computers show as being paid to them, you wont see a CP2000 either.

Ive unknowingly tested this theory on numerous occasions when Ive missed a new EIN on a document, or Ive plugged the1099R figures into the wrong one that was saved in a client file, never once had an issue later down the road.

The employer I worked for, he was notorious for misspelling business names, or using acronyms or a commonly used name of a local business for the name of a issuer, when the name on the document was something very different...it was never an issue.
