The online notary service through iPostal1 charges $25 for a single notarization. We offer this service as a convenience and for those who do not have easy access to a Notary Public nearby. Note: Customers living outside the U.S. who sign up for a U.S. address MUST use this online notary service.If you sign up for more than one iPostal1 address, you can request a session to notarize forms for all mailboxes in the SAME notary session. The discounted cost is $25 for the first form, and $5 for each remaining form in the same session. After signing up at all your locations, please contact iPostal1 Customer Service for instructions on how to schedule an online notary session for multiple locations and get the discount.
