EIN Number for Form 5500

I had been told a long time ago that we needed to get an EIN# specific to the plan and not use the employers on the Form 5500.  Is this no longer the case?  One of our clients got a notice and it would appear that we should be using the employer's EIN# to file the Form 5500.

Sorry if it's a silly questions, just wanted to confirm.  Thanks in advance!

The form calls for the employER id number.  It is sometimes advisable to get a separate plan id number, e.g. if the plan is not on a platform and you need to report distributions on Form 1099-R.  We used to put the plan number on Schedule P but that is long gone/showing my age.  I think the only place now the plan id number would appear on a 5500 form is Schedule R.

Correct - ALWAYS use Employer's EIN on 5500.

ONLY use Trust EIN (plan's do not get EINs but trusts do) on 1099-R and Sched R.

And Bird is showing his/her age by mentioning Schedule P!

I have fond memories of Schedule P
