Medallion Signature Guarantee: Where to Get One and What to Check
A medallion signature guarantee is a certified stamp and signature that securities transfer agents and brokerages use to verify that a signature on transfer documents is genuine and that the signer has the authority to make the transfer. This explanation covers where guarantees are typically issued, what to bring, how to find nearby providers, typical timing and fees, and practical alternatives when a local option is hard to find. The goal is to make it easier to compare providers and prepare before you visit.
What a medallion signature guarantee is and when it is required
The guarantee is a special endorsement applied to transfer forms for stocks, bonds, and certain investment certificates. It links the signer, the signature, and a financial institution that will accept responsibility if the signature is invalid. Institutions commonly ask for this when changing ownership, re-registering shares, transferring an account after an inheritance, or when the paper certificate itself changes hands. Transfer agents and receiving brokerages decide when the stamp is needed.
Where to obtain a medallion signature guarantee and what to check before you go
Common issuing locations include banks, broker-dealers, and credit unions. Some larger brokerage firms issue them directly for customers, while community banks and many credit unions offer them only to account holders. Before traveling to a branch, confirm in writing or by phone that the location provides the guarantee for the type of transfer you need. Ask which documents they require, whether an appointment is needed, and if they charge a fee.
Types of providers and typical availability
Providers fall into three main categories, each with different habits and restrictions. Broker-dealers often serve active investment clients and may limit service to customers who hold accounts with them. National and regional banks may provide guarantees to both customers and non-customers, but many require a relationship. Credit unions commonly limit the service to members. Smaller offices may refer you to another branch or to a participating financial institution.
| Provider type | Typical availability | Common restrictions |
|---|---|---|
| Banks | Wide network; many branches offer service | May require customer relationship or appointment |
| Broker-dealers and investment firms | Often available for account holders | Usually limited to firm clients; corporate accounts may need extra review |
| Credit unions | Member-based; fewer branches | Service usually reserved for members and local branches |
Common eligibility and documentation requirements
Institutions commonly require two forms of identification, at least one government-issued photo ID, and the original signed document or certificate. If you represent an estate, expect to present letters testamentary, a death certificate, or court papers. Businesses need corporate resolutions or officer certificates. Bring account numbers, the name exactly as it appears on records, and any transfer agent instructions. If a document shows a power of attorney, some providers require that the power be recorded or verified ahead of the visit.
How to locate nearby providers and verify service before visiting
Start with the institution that already holds the account or the transfer agent named on the certificate. Their website or customer service line often lists which branches or affiliated firms can issue guarantees. If a specific branch name appears, call and ask to speak to someone who handles securities guarantees. When checking online, look for language about medallion or signature guarantees, not just notary service. Notaries usually cannot issue the guarantee, so confirm the availability of the specialized stamp.
Timing, appointment policies, and potential fees
Many branches issue the stamp during regular business hours, but some require an appointment or prior review of documents. Expect busy periods when processing can take longer; bringing complete documentation tends to speed the visit. Fees vary widely: some banks provide the service at no charge for customers, while others charge a modest flat fee. Brokerage firms may include it as part of account services for clients. Ask explicitly about fees and whether a fee applies to non-customers.
Alternatives if a nearby provider is unavailable
If you cannot find a local issuer, consider contacting the transfer agent for alternate options. Some transfer agents will accept a guarantee from a specified list of participating institutions. A receiving brokerage might accept other forms of verification in specific cases, but acceptance policies vary. Another option is working through the firm that holds the account to have the stamp issued remotely or at a different branch. When distance is a barrier, a phone verification combined with mailed documents sometimes works, depending on the institution.
Practical constraints and accessibility considerations
Service availability often depends on customer relationships, branch staffing, and the issuer’s internal policies. Some providers restrict the guarantee to existing customers or certain account types. Remote or rural areas may have fewer participating institutions, which can add travel time. Accessibility is also an issue for people with mobility limits; ask about curbside service, home appointments, or alternative verification routes. Processing times can vary, so plan for possible delays. If documents include foreign elements, additional verification may be required.
Next practical steps for locating and confirming a nearby provider
Begin by checking the account holder’s financial institution and the transfer agent named on any paperwork. Call to confirm availability, ask precisely which documents to bring, and whether an appointment is required. If you are not a customer, ask whether non-customers are served and whether a fee applies. Keep copies of all documents and a phone contact for the branch or agent. If a local option is unavailable, request the transfer agent’s acceptable alternative procedures before traveling elsewhere.

Checking eligibility, confirming paperwork requirements, and verifying hours before you go reduces the chance of multiple trips. Planning also helps when dealing with estates or third-party authorizations, where extra documents are common. Take clear copies, have account numbers ready, and keep contact information for the transfer agent. These steps help compare options and choose the provider that matches your timing and documentation needs.
