If you are using your virtual mailbox for your business, you must complete Section 7 of the USPS Form 1583. If you’re using the mailbox for personal use, you can skip this section entirely.
7a. Business Name – Write your full business or organization name exactly as it is registered. This should match your official registration or legal documents.
7b. Type of Business – Indicate the kind of business you operate. Examples include:
Online Retailer
Consulting
Nonprofit
Be as specific as possible to avoid confusion.
7c–7g. Business Address – Enter your official business street address (not your virtual mailbox).
Reminder: You cannot use your virtual mailbox address in this section. You must list your business registration address or your home address.
7h. Business Phone – Provide your business phone number, including the area code.
7i. Place of Registration – List where your business is legally registered usually the county and state.
Before submitting, double-check that the rest of the form is complete, attach your required identification documents, and sign where needed.
