  2. The provider name and address used for the Form 1583 steps.
  3. The identity documents the provider says are acceptable.
  4. A quiet browser session where you can complete identity checks without rushing.
  5. A plan for one low-risk test mailpiece after the account is active.

Checklist before changing your mail

Confirm the provider steps

Do not notarize a standalone form if your provider requires a specific upload, packet, or identity flow. Use the steps from the mailbox company first, then choose the notary method that fits those steps.

Protect sensitive documents

Identity documents should stay inside the approved provider or notary system. Do not send ID copies through random email, chat, public forms, or unverified upload pages.

Run one test mailpiece

After the mailbox is active, send one non-sensitive letter or postcard first. Confirm receipt, scanning, forwarding, notifications, and any fees before moving important mail.
