IRS Form 8233 (Exemption From Withholding on Compensation for Independent (and Certain Dependent) Personal Services of a Nonresident Alien Individual) Fax Number

Not the nonresident alien. You give the completed and signed Form 8233 to your withholding agent, your employer or payer, who reviews it and, if satisfied the exemption applies, signs the Part IV certification. From there, it's the withholding agent who mails or faxes a copy to the IRS within 5 days of accepting it, not you.

Yes. A separate Form 8233 is required for each tax year you claim the treaty exemption, for each withholding agent, and for each type of income. It's tied to a specific calendar year and generally needs to be resubmitted if your visa status, student status, or employer changes mid-year.

Your withholding agent has to wait at least 10 days after mailing or faxing the form to the IRS before treating the exemption as approved. If the IRS notifies them your eligibility is in doubt or denied, they must begin withholding immediately. If the form is rejected as incorrect, you can submit a revised version.

Form 8233 covers compensation for personal services, wages and similar income, claimed through your withholding agent. Form W-8BEN generally covers noncompensatory scholarship or fellowship income instead. If you receive both types of income from the same withholding agent and are claiming a treaty exemption on both, you can combine them on one Form 8233.

No. A Central Withholding Agreement, requested on Form 13930, is a separate IRS arrangement mainly used by nonresident public entertainers and athletes to get a reduced withholding rate on their U.S. tour or event income. It isn't a substitute for or a version of the Form 8233 treaty-exemption process.
