  • By telephone at 1-800-829-4933 from 7:00 a.m. to 7:00 p.m. in the fiduciary's local time zone. Assistance provided to callers from Alaska and Hawaii will be based on the hours of operation in the Pacific time zone.

If the estate or trust has not received its EIN by the time the return is due, write “Applied for” and the date you applied in the space for the EIN. For more details, see Pub. 583, Starting a Business and Keeping Records.
