A medallion signature guarantee is often compared to a notarized document, but there's a big difference: A medallion signature guarantee can only be provided by certain financial institutions and used for very specific reasons, most commonly the sale or transfer of securities. Read on to learn more about a medallion signature guarantee, how it differs from a notarized document, and how to obtain one.

What's the difference between medallion signature guarantees and notarized documents?
A notarized document typically only confirms the signer's identity and guarantees that the public is protected from fraud or forgery. A medallion signature guarantee not only confirms the signer's identity, but also their authority to transfer security. In addition, medallion signature guarantees are backed by the assets of the issuing financial institution.
Notarized documents also cover a far wider range of activities than medallion signature guarantees. For example, mortgage documents, property deeds, powers of attorney, wills and trusts, articles of incorporation, contracts, commercial leases, and memoranda of understanding all can and often are stamped by a notary.
It's also far easier to get a document notarized. Only financial institutions can issue medallion signature guarantees, but documents can be notarized at banks, law offices, real estate companies, accounting firms, libraries, town or county clerks, and even some parcel shipping stores.
