Which online notary service is best?
The best online notary service depends on what you’re notarizing, because the platforms have converged on the same $25 sticker price and differentiate everything after it. On July 17, 2026, we fetched the published pricing pages of seven platforms — USA Notary, Proof (Notarize), OneNotary, NotaryLive, NotaryCam, DocuSign Notary, and BlueNotary — and recorded exactly what each one prints. The verdicts below come from those pages alone.
- Best for a single personal document: any flat $25 platform — USA Notary charges $25 per document, all-inclusive, with identity verification, the seal, and delivery covered by one price.
- Best published rate on additional seals: OneNotary, which charges $10.00 for every additional seal, versus $15 at Proof.
- Best for signers outside the U.S.: NotaryCam, the only platform whose pricing page publishes international coverage — “145 countries.”
- Best for enterprises: Proof and DocuSign, which sell dedicated business plans; DocuSign positions its own product for organizations notarizing 200+ documents per year.
- Not for consumers: BlueNotary publishes no consumer notarization price — its pricing page sells subscriptions to notaries and businesses.
Disclosure up front: USA Notary publishes this guide and appears in the comparison. That’s why every figure here carries the source page it came from, retrieved on the same day — check any of them yourself.
What does each online notary service cost?
Advertised entry price is where every platform looks identical. The full published price list is where they separate.
What seven online notary pricing pages actually publish, fetched July 17, 2026.
| Platform | Entry price (as printed) | Additional seal | Pricing unit | Notable published extras |
|---|---|---|---|---|
| USA Notary | $25 per document | Not published — each document is $25 all-inclusive | Per document | Flat rate covers ID check, video session, seal, delivery |
| Proof / Notarize | $25 with the Notarize Network | $15 | Per seal | $10 per additional signer · $10 on-demand witness · $4 eSign per transaction |
| OneNotary | $25 (1 stamp, 1 signer) | $10.00 | Per notarization/seal | $10 per additional signer · $15 OneNotary witness · free pay-as-you-go tier |
| NotaryLive | $25 per Session* | Not published | Per session | The asterisk has no footnote on the page · bulk tiers from $23/document |
| NotaryCam | $25 Per Seal (includes one signer) | Not published (prices by signer/document instead) | Per seal | $10 per additional signer · $79 fee for signers without a U.S. SSN · $175/document wills & trusts |
| DocuSign Notary | ”Starting at $25*” via partner OneNotary | Not published | — | Own product aimed at orgs notarizing 200+ documents/year |
| BlueNotary | No consumer price published | Not published | Per session (business plans) | $37/notary/month subscription · $10 on-demand witness |
Three of the seven platforms don’t publish a complete consumer price on the pages we fetched: NotaryLive (no additional-seal rate and an asterisk that resolves to nothing), DocuSign (routes consumers to a partner with a “starting at” price), and BlueNotary (no consumer rate at all). When a platform doesn’t print a number, we say “not published” rather than guessing — and you should treat any figure a comparison site invents for those cells with suspicion.
What do “per seal,” “per document,” and “per session” actually mean?
The pricing unit is the single most confusing thing about comparing online notary services, and none of the platforms explains it side by side. The three units are not interchangeable:
- Per seal (Proof, NotaryCam, OneNotary): a seal is one notarial act. One document can require several seals — a set of estate documents or a loan package routinely does — so a per-seal platform bills each act: $25 for the first, then $15 (Proof) or $10 (OneNotary) for each additional one.
- Per document (USA Notary): the document is the unit. USA Notary’s pricing page states the $25 “flat rate covers identity verification, a live video session with a commissioned notary, the electronic notarial seal, a tamper-evident certificate, and instant digital delivery — with no hidden fees.”
- Per session (NotaryLive): the meeting is the unit. NotaryLive’s homepage prints “$25 per Session*” — wording that suggests one video call covers what happens inside it, but the site publishes no policy on how many seals or documents a session includes, and the asterisk has no footnote anywhere on the page.
Before you pick a platform, count the seals your paperwork needs — the notary certificate blocks on the document tell you — and run the arithmetic in that platform’s unit. What notarization actually certifies doesn’t change between platforms; the billing math does.
How does each platform compare?
USA Notary
USA Notary charges $25 per document with everything included, as published on its pricing page. There is no consumer subscription; commissioned notaries who use the platform professionally pay a separate membership starting at $19.95/month. The service connects signers in all 50 states with commissioned notaries over a recorded video session — the mechanics are covered in how USA Notary runs a remote session. This is our platform, which is exactly why every competitor figure in this guide links to its source.
Proof (Notarize)
Proof — the company behind Notarize — publishes the most complete consumer price list of the seven: $25 with the Notarize Network, $15 for each additional seal, $10 for each additional signer, $10 for each on-demand witness, and eSign at $4 per transaction. Its network is available 24/7 per both its consumer and business pages. Two things worth knowing: its business Pro plan prices additional seals lower ($10) than consumers pay ($15), and the consumer page also discloses the platform’s notary economics — notaries earn $5 per completed on-demand notarization.
OneNotary
OneNotary charges $25 for one stamp and one signer, $10.00 for every additional seal, $10.00 for every additional signer, and $15 for a OneNotary-provided witness. Its pay-as-you-go tier is free with no monthly commitment, and it claims 24/7 availability. OneNotary also powers DocuSign’s consumer notarization flow — DocuSign’s own page routes individuals to “our trusted partner OneNotary.” Its $10 additional-seal rate is the lowest published in this comparison.
NotaryLive
NotaryLive prints “$25 per Session*” for individuals and “24/7/365” availability, “valid in all 50 states.” The session-based unit is genuinely different from per-seal billing — but the platform publishes no additional-seal price, and the asterisk after “per Session” has no footnote anywhere on the page. Businesses get published bulk tiers: $23 per document at 20–50 documents/month with no monthly fee. Its Premium bulk tier (51–200 documents/month) lists “No Extra Fee for Notarizations Outside of the US (For US Citizens)” — an international allowance, but only inside a business plan.
NotaryCam
NotaryCam charges $25 Per Seal including one signer on its consumer “Notarize Now” plan, with a 24/7 notary network — and it is the only platform here that publishes international coverage: “145 countries.” The trade-offs are also printed on the same page: $10 per additional signer, a $79 fee for signers without a U.S. SSN (the largest add-on fee in this comparison), $175 per document for wills and trusts, and limited 7am–11pm ET hours on its real-estate and wills plans.
DocuSign Notary
DocuSign’s notary page serves two audiences. Individuals are routed to partner OneNotary at “Starting at $25.*” DocuSign Notary itself — the in-house product — is described as “a good fit for enterprises and organizations that notarize 200 or more documents per year” using their own notaries, with 24/7 access to a notary pool. Its page also states international signers are generally supported “as long as the notary public complies” with their state’s law.
BlueNotary
BlueNotary sells subscriptions to notaries and businesses, not signers: $37 per notary per month with two free sessions, a Notary Pro tier at $24.75/month, and per-use business fees. No consumer notarization price appears on its homepage or pricing page. If you’re a signer with one document, this platform’s published pricing simply doesn’t address you; if you’re a notary choosing software, it’s a different comparison — covered platform-by-platform, with published fees and payouts, in our best RON platforms for notaries comparison.
Which online notary is cheapest for multiple documents?
Run the published rates for a job that needs two seals — a common scenario for powers of attorney paired with a supporting affidavit:
- OneNotary: $35 — $25 first notarization + $10 additional seal
- Proof/Notarize: $40 — $25 first seal + $15 additional seal
- USA Notary: $50 — $25 × 2 documents, each all-inclusive
- NotaryCam / NotaryLive: not computable — neither publishes a second-seal rate
The arithmetic flips as documents get bigger: a per-document rate covers a document no matter how many notarial acts it needs, while per-seal billing grows with every certificate block. And every total above assumes the platform’s published price is the whole story — on the three platforms with incomplete price lists, it may not be. Whichever you choose, confirm online notarization is accepted for your document and state before the session; per the National Association of Secretaries of State, 47 states and the District of Columbia have laws allowing remote e-notarization.
