Form 1583 is the signed, notarized form your U.S. virtual mailbox provider needs before it will open or scan a single envelope, and sellers in Argentina usually complete it through a video session with a commissioned U.S. notary rather than a trip anywhere. The steps below follow the form from the first upload to the moment the provider marks the account approved.
Why an online seller in Argentina ends up here
A marketplace seller in Palermo restocking inventory from a supplier in Asia, a dropshipper in Rosario handling customer returns, and a small brand in Cordoba waiting on a sample shipment from a U.S. manufacturer all land at the same point: the carrier or the manufacturer will only ship to a U.S. address, and the bank behind the seller account wants one too. A virtual mailbox solves that, but the box stays empty until Form 1583 clears review.
The walkthrough, step by step
- Open the account with your chosen mailbox provider and download the blank Form 1583 it sends you, rather than a generic copy found elsewhere.
- Fill in your legal name and the business name exactly as they appear on your seller account and any formation paperwork, matching punctuation and spacing.
- Book the online notarization session and have your passport and second ID within reach before the call starts.
- Join the video session, show both IDs to the notary, and sign the form electronically while the notary watches.
- Receive the notarized PDF and upload it to your provider's dashboard along with the scanned copies of your IDs it requested.
- Wait for the provider's review team to confirm the names, the address format and the signature, then watch for the account to switch to approved.
The IDs a seller in Argentina usually gathers
- A valid passport, which almost every mailbox provider lists as the primary photo ID.
- A second document, often a national ID card or a recent utility bill showing your home address, depending on what your specific provider's accepted list names.
- A business paper if the mailbox is opened under a company name, such as the formation certificate for the entity receiving supplier mail.
The guide on Form 1583 ID requirements and proof of address lists what most providers ask to see before they approve anything.
Scheduling the session from Buenos Aires or Rosario
Argentina sits only a modest distance ahead of the U.S. East Coast in the workday, which gives sellers more overlap than they expect when booking an evening slot. A stable connection and a working camera matter more than the exact hour chosen, since the notary needs a clear view of your face and your documents throughout the call.
What slows down an online seller's approval
- The business name on the form does not match the name on the seller account or the supplier's shipping label.
- A second ID does not appear on the provider's own accepted list, even though it is a valid Argentine document.
- The form is signed before the business section is filled in, which some providers send back as incomplete.
- Return labels or supplier invoices arrive at the mailbox before the account has cleared review, which delays scanning until approval catches up.
Checking your documents against the provider's list before booking the session avoids most of this back and forth.
Keeping the mailbox running after approval
Once the account is approved, most of the ongoing work is routine: a supplier's package arrives, the provider scans the label and the packing slip, and a seller decides whether to have it forwarded, held or opened for a closer look. A return label mailed back by a customer follows the same path in reverse. The part worth planning ahead of time is what happens when the business grows beyond one person, since adding a second signer to the account usually means a fresh Form 1583 for that signer rather than an update to the existing one.

Questions we hear often
Can an online seller in Argentina notarize Form 1583 without traveling?
Usually, yes. Most sellers complete the form through an online session with a U.S. notary, as long as the mailbox provider accepts a remotely notarized form.
What happens between upload and approval?
The provider's review team checks your name, address format and signature against your submitted IDs before switching the account to approved, which is why matching details matter.
Which second ID works alongside a passport?
Often a national ID card or a recent document showing your home address, but check your specific provider's accepted list rather than assuming.
Can returns and supplier mail arrive before the account is approved?
They can arrive, but most providers hold scanning and forwarding until the account clears review, so approval is worth finishing before heavy shipping begins.
Does a business name change anything on the form?
Yes. If the mailbox is under a company name, that name must match your formation paperwork exactly, and the provider may ask for that document separately.
