Form 1583 from Canada for a new LLC: company form versus your own

A founder who just filed a U.S. LLC and needs a business address runs into a form that looks like one document but actually works as two: a personal Form 1583 for each individual tied to the mailbox, and a business section that covers the LLC itself. Both get notarized, and mixing them up is the most common reason a provider sends the whole file back.

This guide walks through what changes once the mailbox is for a company rather than a single person, and how the online session runs for a founder based in Canada.

Why a new LLC needs a mailing address at all

A bank opening an account for the LLC, a payment processor running a compliance check, or a state itself wanting a reachable address all expect a physical mailing address tied to the company, not just an email. A virtual mailbox fills that gap, but the provider cannot activate it until the paperwork naming both the company and its signers is complete and notarized.

The company section versus each person's own form

• The business section. It names the LLC exactly as filed, usually alongside a copy of the formation certificate, and lists who is authorized to act for the company at that address.
• Each individual's own form. Every member, manager or officer who will be tied to the mailbox completes and signs a personal section with their own identification, separate from the company details.
• One notarization, both parts checked. The notary reviews both sections in the same session rather than treating them as two separate appointments.

The guide on Form 1583 for an LLC goes deeper into what changes when the mailbox belongs to a company rather than a person.

Booking the session from Canada

Time zones across Canada vary enough that a founder in Vancouver and one in Toronto are not choosing from the same slots, but both land close enough to the U.S. East Coast that evening availability usually works for either. The session itself needs a stable connection, a working camera, and the original government ID in hand, not a scan. The notary verifies identity, confirms the business details against the formation certificate, and watches each required signer sign electronically before applying the notarial certificate and seal.

Who actually needs to appear for a multi-member LLC

When an LLC has more than one member, the provider usually wants each person whose name appears in the business section to complete their own identification and signature, not just the founder who filed the company. A member who lives in a different Canadian province, or who is not available the same week, can usually join a separate session rather than waiting for everyone to be free at once, as long as the business section stays consistent across every form submitted.

Mistakes that send a company's form back

• Listing the company's trade name instead of the exact legal name on the formation certificate.
• Having only the founder sign when the provider expects every listed member to complete their own form.
• Submitting the business section before the formation certificate is finalized, so the names do not match.
• Mixing a member's personal address with the company's business address on the wrong line.

What changes once the mailbox goes live

Once the provider accepts the notarized form, the mailbox starts receiving mail addressed to the LLC: state notices, bank correspondence, and vendor letters that a founder based in Canada would otherwise have no way to collect. Scanning and forwarding follow whatever plan the founder picked with the provider, and that plan only starts once both the business section and each required personal form have cleared review, not before. A founder adding a second member later, say a Canadian co-founder who joins after the initial filing, goes through the same personal section process rather than reopening the whole business file.

How TR Signing Group handles it

TR Signing Group runs these sessions from Bayonne, New Jersey: a pre-check of the formation certificate and each signer's identification, then a call held by Tanim Raquib, a commissioned New Jersey notary public, scheduled for a time that works from Canada. A single founder's form gets the same attention as a filing with several members.
