You need a medallion signature guarantee. Your bank said no. You called another bank. They said no too. A credit union had never heard of it. The one branch that said yes told you to come back in three weeks with an appointment and six months of account history.
If this sounds familiar, you are not alone. It is the single most common experience people describe when they contact us.
What Is a Medallion Signature Guarantee?
A medallion signature guarantee is a special certification that verifies your identity and your authority to sign documents related to securities transfers — stocks, bonds, mutual funds. It is legally required for most transactions involving the transfer of ownership of securities.
Unlike a notary stamp, which simply witnesses a signature, a medallion guarantee means the institution providing it accepts financial liability if the signature turns out to be fraudulent. That liability is what makes the stamp meaningful — and what makes banks reluctant to provide it.
For a full explanation, see our guide: What is a Medallion Signature Guarantee?
Why Banks Stopped Offering Medallion Guarantees
This is not a temporary situation. It reflects a structural shift in how banks think about the service, and it is unlikely to reverse.
High Liability, Low Revenue
When a bank stamps your document, it is guaranteeing that the signature is genuine and that the signer has the legal authority to act. If something goes wrong — a forged signature, an unauthorized transfer — the bank that applied the stamp is financially responsible. For most banks, this liability simply is not worth the risk. A typical branch might get a handful of medallion requests per year. Training staff, maintaining compliance protocols, and carrying the liability for a service that generates almost no revenue does not make business sense.
Complex Transactions
Medallion guarantees often involve estates, trusts, corporate entities, and other situations with layered legal requirements. These are not simple transactions. A single mistake can expose the bank to significant financial loss. Most branch employees are not trained to evaluate whether someone has the legal authority to act as an executor, trustee, or corporate officer — and the bank knows it.
Consolidation and Cost Cutting
As banks have moved toward digital services and streamlined their branch operations, specialized services like medallion guarantees have been among the first to go. Fewer branches, fewer trained staff, fewer services that do not generate revenue.
Regulatory Burden
Participating in a medallion program (STAMP, SEMP, or MSP) comes with ongoing compliance requirements. Many banks have decided the administrative overhead is not justified for the volume of requests they receive.
None of this is the fault of the individual bankers you speak with. They are often just as frustrated as you are, because they know how difficult it is to find this service elsewhere.
The Common Experience
If you have been through this, the pattern will be familiar:
You call your bank and are told they do not offer medallion guarantees. You call a second bank and get the same answer. You try a credit union — they have never heard of it. You call a larger national bank. They say they offer the service, but only at certain branches, and the person who handles it is unavailable.
You finally find a branch that says yes. But then you learn about the requirements: six months of account history, an appointment three weeks out, a transaction value limit that might not cover your transfer, and a list of documents you are not sure you have.
This cycle of calling five, ten, or even fifteen institutions is extremely common.
The Requirements Banks Impose
Even when you find a bank that still provides medallion guarantees, you will typically encounter several conditions:
- Existing customer requirement. Most banks will not stamp documents for non-customers. Some require that you have held an account for a minimum period, often six months or more.
- Minimum account balance. Some institutions require you to maintain a certain balance, sometimes $10,000 or more, before they will provide the service.
- Appointment required. Walk-ins are rarely accepted. You may need to schedule days or weeks in advance, and the service may only be available at specific branches.
- Transaction value limits. Banks set limits on the dollar value of the transaction they are willing to guarantee. If your securities exceed that limit, they may decline.
- Limited transaction types. Many banks will not stamp documents for estates, trusts, or corporate transfers. These are considered higher-risk, and the bank may not have the expertise or appetite to take on the liability.
The result is that even when a bank technically offers medallion guarantees, the practical barriers can make it nearly impossible to actually get one.
The Hidden Costs of the Bank Route
Even when the stamp itself is free, the bank route has real costs:
- Time. One to three weeks of phone calls, scheduling, and branch visits is common.
- Travel. Multiple trips to find a branch that offers the service and has a trained officer available.
- Opportunity cost. Securities transfers are often time-sensitive. Delays can mean missed deadlines, additional fees from transfer agents, or market exposure you did not intend.
- Frustration. The emotional toll of being bounced between institutions while managing an estate, a retirement rollover, or a time-sensitive transfer.
What You Can Do Instead
You have options beyond calling banks:
Try a different branch. If you have an account at a major bank (Bank of America, Chase, Wells Fargo), call their main branch rather than a neighborhood location. Larger branches are more likely to have a trained medallion officer. But the same account history and transaction type restrictions apply.
Use your broker. If you hold a brokerage account at Fidelity, Schwab, or a similar firm, they may provide medallion stamps — but typically only for transactions involving their own platform. If your securities are held at a transfer agent like Computershare or EQ, your broker may decline.
Open a new bank account. This guarantees access to the service — in six months, after you meet the account history requirement. Not a realistic option for time-sensitive transfers.
Use an online medallion guarantee service. This is what we built eSignature Guarantee to do. We are a STAMP-participating institution that provides medallion signature guarantees entirely online. No bank relationship required, no six-month wait, no branch visit. We handle all transaction types — estates, trusts, corporate, individual — starting at $300, with processing typically within 5 business days.
How eSignature Guarantee Works
The process is straightforward:
- Create an account and verify your identity. This takes about 10-15 minutes and can be done from your computer.
- Tell us about your transfer. Answer a few questions and we will tell you exactly what documents you need. You can also use our interactive questionnaire to identify your requirements.
- Submit your documents. Upload the forms that need to be stamped, along with supporting documentation for your transaction type.
- Compliance review. A dedicated compliance officer reviews your submission. If anything is missing, we will let you know promptly.
- Medallion stamp applied and documents returned. Once approved, we apply the stamp and ship your documents back via 2-day shipping, with scanned copies sent by email.
Our stamps are accepted by all major transfer agents, including Computershare, EQ, AST, BNY Mellon, and others.
The Bottom Line
Banks make medallion signature guarantees difficult because providing them is high-liability, low-revenue work that most branches are not equipped to handle. This is not going to change. If anything, it is getting worse as banks continue to consolidate and cut specialized services.
You do not have to navigate that system. eSignature Guarantee was built specifically to solve this problem — one service, one clear process, one price.
