USPS Form 1583 for a Florida virtual mailbox
What the mail authorization does, what to prepare and what it does not prove.
Prepare your identification
USPS requires two acceptable forms of identification, including a photo ID, for a private mailbox application. Check the accepted document list, validity and address evidence before arranging notarization. A document accepted for one service may not qualify for another.
Ask how signing is handled
Confirm whether the operator supports remote online notarization, an in-person notary or another permitted process. Your Tax Base lists optional online notarization at $35 per form. That is separate from its annual plan and is not a universal notary price.
Keep its purpose clear
An approved mail authorization is not a Florida driver license, proof that you live at a property or a tax-residency determination. Save a copy and follow the provider’s process when your identification, recipients or forwarding destination change.
