Can a business mailbox receive mail for multiple names?
Straight answer
Yes. One private mailbox can receive mail for a business and for each individual authorized to receive mail at that address, but every named person must complete their own Form 1583 with two IDs. Mail addressed to a name with no Form 1583 on file should not be accepted. Minors are listed on a parent's or guardian's form.

Does the business itself need a Form 1583?
The business is named on the form of the person who applies for it, along with the members or officers whose mail will be delivered. Each of those people also signs their own form.
Form 1583 is completed by a person, not an entity. For a business box, the applicant lists the firm name and the individuals who will receive mail at the address. USPS then expects one signed form per person, each with a primary photo ID and a secondary traceable ID, witnessed in person, over live video, or before a notary. The business name on one form does not cover an officer who has not signed.
What do I do with mail addressed to a name that is not on file?
Do not place it in the box. Hold it, ask the account holder to add the person with a new Form 1583, and return it if they cannot.
A CMRA may only receive mail for addressees who have a Form 1583 on file. Letters for an unfamiliar name at a business box are common: a new hire, a contractor, a former partner. The right move is to notify the account holder, get the new person's form and IDs, enter them in the CRD, and only then deliver. Until that happens, the item goes back to the Post Office rather than into the box.

How does Innbocks handle business accounts with several names?
A business account carries the entity plus named addressees, and each named person completes their own Form 1583 through the guided flow. Arrival matching only offers names with an approved form.
When you set up a business account in Innbocks, you add the business and each individual as a named addressee. Each individual gets their own Form 1583 flow: their ID is read to prefill the form, they notarize remotely or at your counter, and you approve from the dashboard. When staff photograph an arriving envelope, OCR reads the addressee and suggests the matching account. A name whose Form 1583 is still pending is never suggested, so mail for an unapproved person is caught at intake rather than found later.
Envelope matching
OCR reads the envelope at intake and suggests the addressee with an approved Form 1583.
Can family members share one mailbox?
Yes, on the same rule. Each adult who receives mail completes their own Form 1583, and minors are listed on a parent's or guardian's form.
A household box works like a business box: the account holder signs, each additional adult signs, and children appear on a parent's form rather than filing their own. Innbocks treats these as named addressees on one account, so the family pays one plan and each adult sees their own mail in the customer portal and the Innbocks app.
Business accounts, one Form 1583 per person
Innbocks puts the business and every named addressee on one account, runs each person's Form 1583, and only matches mail to approved names.
