cooperative must use an EIN for any tax-related purpose even if the entity doesn’t have employees.

However, don’t apply for a new EIN if the existing entity only (a) changed its business name, (b) elected on Form 8832 to change the way it is taxed (or is covered by the
default rules), or (c) terminated its partnership status because at least 50% of the total interests in partnership capital and profits were sold or exchanged within a 12month period. The EIN of the terminated partnership should continue to be used. See Regulations section 301.6109-1(d)(2)(iii).

must have an EIN. For more information on grantor trusts, see the Instructions for Form 1041.
