Signature Guarantee Service

Signature Guarantee is a free service provided to members at certain Austin Telco Branch to assist in the purchase, sale, or transfer of their stocks, bonds, mutual funds, and other securities. To allow securities transactions, a signature must be "guaranteed" for the benefit of the member's stockbroker or other financial representative. We follow strict guidelines when guaranteeing a signature, using the Securities Transfer Agents Medallion Program (STAMP) certification to ensure that the guaranteed signature is covered within the monetary limits of our bond. Our bond company limits this service to our being able to guarantee signatures for only Austin Telco members. To help facilitate the signature guarantee, Austin Telco members must provide the following:

  • ATFCU account number.
  • Government issued picture ID (driver's license, state ID, Military ID, etc.)
  • The form letter from your brokerage firm or financial institution on their company letterhead requesting the signature guarantee.

Signature guarantees are only used with securities. If you have any questions about signature guarantee, please contact us at 512-302-5555 or stop by an Austin Telco branch that provides this service. Please keep in mind that only certified personnel may provide this service.
