After reading a topic article on this site regarding the 4852, it suggests calling the IRS and they will send out a 4852 to me. Will the IRS provide the full EIN for the employer (now defunct)? I was able to pull the W-2 details from the tax transcript provided by IRS portal except for the EIN which is truncated. This has prevented me from filing online through FreeTaxUSA. Are there any ways to find the employer EIN? Am I best to just complete the 4852 that I already pulled from the IRS and mail in my return?
