A Signature Validation Program Stamp may be executed by any “eligible” issuer participating in the Securities Transfer Agents Medallion Program 2000 (STAMP2000). Eligible issuers include Commercial Banks, Trust Companies, Savings Associations and Credit Unions as defined by the Federal Deposit Insurance Act. Also included are member firms of a domestic stock exchange. You should verify with the institution that they are an acceptable (eligible) guarantor prior to signing. A Notary Public is not acceptable.
