Fax Form 8821 to the IRS CAF unit

Form 8821 (Tax Information Authorization) is faxed to the same CAF units as Form 2848: Memphis (855-214-7519), Ogden (855-214-7522) or the international unit (855-772-3156), based on the taxpayer's address.

Like the 2848, a faxed 8821 needs a handwritten signature — the e-signature path exists only inside the IRS online portal.
