The cheapest online notary, by situation
For one signer and one seal, OnlineNotary.net lists the lowest price ($19.95), but only for US residents and not around the clock. Every 24/7 service we checked starts at $25, so the real difference is in the add-on fees: extra seals, extra signers, witnesses and page counts.
The short answer
- Lowest headline price: OnlineNotary.net lists $19.95 per signer, but only for US residents with proof of a US residential address, and it lists hours of 10AM to 2AM daily (no time zone given).1
- Cheapest 24/7 option: a tie at $25 for one signer and one seal: Notarize, NotaryCam, OneNotary, BlueNotary and NotaryLive.23456
- Several seals: NotaryLive, which says it doesn't charge for additional seals.6
- Two or more signers: BlueNotary or NotaryLive, at $5 per extra signer.56
- You need the platform to supply a witness: BlueNotary or NotaryLive, at $10 per witness.56

The math for each service
Each row adds the company's listed add-on fees to its base price.
| Service | 1 signer, 1 seal | 1 signer, 3 seals | 2 signers, 1 seal | 1 signer + 1 platform witness |
|---|---|---|---|---|
| OnlineNotary.net | $19.95 | $29.95 | $39.90 | not listed |
| Notarize | $25 | $55 | $35 | $40 |
| NotaryCam | $25 | $75 | $35 | not listed |
| OneNotary | $25 | $45 | $35 | $40 |
| BlueNotary | $25 | $41 | $30 | $35 |
| NotaryLive | $25 | $25 | $30 | $35 |
The fees behind these numbers:
- OnlineNotary.net: $19.95 per signer, $5 per additional notary stamp per document; it says there are no extra fees for additional jurat, acknowledgment or attestation pages.1
- Notarize: $25, plus $15 per additional seal, $10 per additional signer and $15 per on-demand witness.2
- NotaryCam: $25 per seal including one signer, plus $10 per additional signer.3 The three-seal figure assumes the $25 applies to each seal.
- OneNotary: $25 per session (one stamp, one signer), plus $10 per additional stamp, $10 per additional signer and $15 for a OneNotary witness.4
- BlueNotary: $25 for one stamp, plus $8 per additional stamp, $5 per additional signer and $10 for a witness from BlueNotary; a witness you invite yourself is $0.5
- NotaryLive: $25 per session with the first 25 pages included, plus $5 per additional signer, $5 per additional 25 pages and $10 per on-demand witness; no extra charge for additional seals or signatures.6
Fees that change the answer
- Long documents. NotaryLive adds $5 for each additional 25 pages beyond the first 25.6 A 40-page document is $30 there. The other five pricing pages we checked list no page-count fee for online sessions.12345
- Bringing your own witness. BlueNotary charges $0 for a witness you invite yourself.5 If your document needs witnesses, see our power of attorney guide for how witness rules work.
- Paying only when it works. NotaryLive says you're only charged when the session is completed.6 OnlineNotary.net says you pay after the notarization, offers a full refund if your recipient doesn't accept the document, and a free redo if a mistake is made.1
- Sending the document to others to sign. Notarize charges $4 per eSign transaction from its account.2
If you don't have a US Social Security number
The ID check is where prices can jump for people abroad or without an SSN:
- NotaryCam lists a $79 fee when the signer or signers have no US SSN.3
- NotaryLive says you can notarize from outside the US, and offers a "Personal Verifier" option if the identity quiz is unavailable or fails.6 Whether that option costs extra: unknown (not stated on its pricing page).
- Notarize/Proof offers a selfie-based identity check if you have no SSN or ITIN, but most transactions still need a current or former US address.7 Any extra fee for this: unknown.
- OnlineNotary.net serves US residents only, though it says US residents living abroad pay no extra fees.1
If your document is USPS Form 1583 for a virtual mailbox, our Form 1583 guide covers the no-SSN route in detail.
Before you pay: three checks
- Count the seals and signers. These drive the price more than the headline rate. If you aren't sure how many seals your document needs, ask the provider's support before starting.
- Ask the recipient whether they accept online notarization. Proof's help center tells signers to check with whoever receives the document first.8
- Check your state's rules. Your state's online notarization law and fee cap are on its page in our state-by-state guide. A state fee cap limits what the notary may charge, but platforms may add their own fees on top; our Florida page has an example.

Frequently asked questions
What is the cheapest online notary?
For a single signer and a single seal, OnlineNotary.net lists $19.95 per signer, the lowest headline price we found. It serves US residents only and lists daily hours of 10AM to 2AM rather than 24/7. Notarize, NotaryCam, OneNotary, BlueNotary and NotaryLive all list $25 for one signer and one seal.
Which online notary is cheapest for a document with several notary seals?
NotaryLive says it doesn't charge for additional seals, so a one-signer document with three seals is still $25 there. BlueNotary lists $8 per extra stamp ($41 for three), OnlineNotary.net $5 per extra stamp ($29.95), OneNotary $10 ($45), Notarize $15 ($55), and NotaryCam prices per seal ($75 if each seal is $25).
Which is cheapest with two signers?
BlueNotary and NotaryLive both list $5 per additional signer, so two signers on one seal comes to $30. Notarize, NotaryCam and OneNotary list $10 per extra signer ($35). OnlineNotary.net charges $19.95 per signer ($39.90).
Are there hidden fees?
The ones we found on public pages: NotaryCam lists a $79 fee when a signer has no US Social Security number; NotaryLive charges $5 per additional 25 pages after the first 25; and witnesses supplied by the platform cost $10 to $15 where a price is listed. State technology fees or taxes aren't included in these figures.
