Send a fax nowEven as most government services move online, fax remains a standard channel for sensitive or time-stamped submissions — proof of identity documents, signed legal forms, appeals, and correspondence that needs a verifiable paper trail. Many agencies still list a fax number as the primary or backup method for specific forms precisely because fax transmissions are well understood legally and don't carry the same security concerns as email.
Form 2848 (Power of Attorney) routes to 855-214-7519 (Eastern states), 855-214-7522 (Western states), or 855-772-3156 (international). Form SS-4 (EIN applications) faxes to 855-641-6935 for domestic applicants. These are current IRS-published numbers, but the IRS notes they can change without notice.
