We have found that, particularly with new entities with brand new EINs, the IRS computing center in Detroit appears not to have updated (current) data in their files. We'd get back a warning that the number had never been issued; yet we had actually seen the number assignment letter from the IRS itself! We haven't seen the same sort of scenario when it comes to SSNs for individuals (not surprising, since virtually all native-born citizens have SSNs long before they ever cause a CTR to be filed!).
Anyhow, we often find that the messages from the IRS stop after about a month. I assume they ultimately receive an updated file from IRS-central, or whatever the EIN-issuing authority might be called.
