How to get Form 1583 notarized online, provider by provider
Each provider handles the Form 1583 witness step differently. Traveling Mailbox verifies your two IDs and e-signature on a video call with its own team and says no notary is needed; iPostal1 uses an online notary provider for $25, or your mail center may witness you in person for a small fee; Anytime Mailbox routes you to an online notary partner for what it calls a nominal fee, or to an in-person appointment with your mail center operator (checked October 27, 2026).
Last updated: October 27, 2026. Provider details come from each provider’s own site, checked that day: iPostal1’s homepage (“How iPostal1 Works”), Anytime Mailbox’s USPS Form 1583 page and FAQ, and Traveling Mailbox’s Form 1583 page and Terms of Service. The ID rules are on our Form 1583 checklist.

What’s the same no matter which provider you pick?
USPS Form 1583 authorizes a CMRA (the mailbox company) to receive your mail. Every U.S. provider needs it before it can hand you mail, and every one asks for two IDs: one with your photo and one that shows your current address. What differs is who witnesses your signature and how much that costs. Our Form 1583 checklist covers which IDs count. This page covers the witness step.
Form 1583 witness options by provider
| Provider | Online option | Published cost | In-person option |
|---|---|---|---|
| iPostal1 | Its “secure and convenient online notary provider” | $25 | Your mail center may let you sign in front of its staff for a small fee |
| Anytime Mailbox | Click “Use Online Notary” during signup for a live video call with a licensed notary; partners operate 24/7 | “Nominal fee” (no amount on its Form 1583 page) | Book an appointment with your mail center operator, who uploads the form and IDs for you |
| Traveling Mailbox | Video appointment with Traveling Mailbox’s own team, which verifies your IDs and e-signs the form with you | No notary needed, per its Form 1583 page | Not described; mail is processed at its center in Sanford, NC |
iPostal1: online notary for $25
After checkout, iPostal1 assigns your mailbox number and sends verification instructions. For U.S. locations, it says Form 1583 must be completed, notarized, and filed with two forms of ID. To notarize without going to your mail center, you use iPostal1’s online notary provider for $25. Some mail centers will witness you in person for a small fee instead. iPostal1 locations outside the U.S. use a separate identity verification process. More in our iPostal1 review.
Anytime Mailbox: online notary partner or your operator
- Fill out Form 1583 in your Anytime Mailbox account.
- Click “Use Online Notary” to go to the notary portal.
- Join a short video call with a licensed notary, who checks your identity and watches you sign.
- The notarized form goes to Anytime Mailbox automatically, so you don’t upload it yourself.
Anytime Mailbox says this is the simplest route for non-U.S. residents, and that foreign IDs are accepted if they match its accepted ID types and are in English. If you add an authorized person who can collect your mail, that person must join the same notary session and verify their identity too. Anytime Mailbox calls the online notary cost a “nominal fee” but doesn’t print the amount on its Form 1583 page, so check the price on the notary screen before you pay. It says you only need a new form if your information changes.
Traveling Mailbox: video verification without a notary
Traveling Mailbox’s Form 1583 page says a notary isn’t required. After you subscribe, you complete the form in your account (it recommends a desktop or laptop), then schedule a video appointment. Its team checks your two IDs, e-signs the form with you, and finishes setup. It says appointments can take as little as 5 to 10 minutes and work for customers overseas. Each name on the mailbox needs its own two IDs.
How to prepare for an online notary or video session
- Two current IDs ready: a photo ID and an address ID. The name and address must match what you typed on the form. See the checklist.
- A device with a camera: a webcam or a phone that supports video calls. Traveling Mailbox recommends a desktop or laptop for filling out the form.
- Don’t sign early: Anytime Mailbox’s instructions say to sign only during the notary session.
- Everyone on the box attends: anyone you add who will receive or pick up mail needs their own IDs and, at Anytime Mailbox, must join the session.
- Budget the fee: $25 at iPostal1; check the amount on screen at Anytime Mailbox.
What if I switch providers later?
Form 1583 authorizes one specific CMRA, so a new provider needs a new form, even if your old one was approved. Plan the notary step before you cancel anything. Our switching guide shows the overlap plan.
