A Medallion Guarantee is a special stamp that’s used when you sell or transfer US securities. It confirms that the signature authorizing the sale or transfer is genuine and that the signer has the legal capacity and authority to sign the document.
Each Medallion Guarantee has a specific coverage limit that is identified by the alpha prefix on the stamp. If the value of the transaction exceeds the limit, the MSG will be rejected. See Alpha Prefix and associated coverage limits on table provided below. In the case of forgery, the financial institution providing the medallion stamp will accept liability through the Medallion program for amounts up to the associated coverage limit.
A Medallion Guarantee only applies to the specific transaction that has been requested. It does not authorize a party to perform future transactions or to obtain account specific information.
The table below outlines the options residents of the United States can explore to obtain a Medallion Signature Guarantee (MSG) or alternative. Individuals should contact the provider to determine the requirements to obtain an MSG and what fees may apply for the service.
