Bank of America Medallion Signature Guarantee: Requirements, Process, and Alternatives

What you need to know about getting a medallion signature guarantee from Bank of America — eligibility requirements, common rejection reasons, and what to do if your branch says no.

March 31, 2026 | by eSignature Guarantee

If you need a medallion signature guarantee and Bank of America is your bank, you may be able to get one — but it is not as simple as walking into a branch.

Bank of America is one of the larger institutions that still participates in the STAMP medallion program. That said, getting a stamp from them involves meeting specific requirements, finding the right branch, and hoping the transaction falls within their comfort zone.

Here is what to expect.

Does Bank of America Offer Medallion Signature Guarantees?

Yes, Bank of America does offer medallion signature guarantees. However, the service is not available at every branch, and not every customer qualifies. Whether you can actually get a stamp depends on several factors, including your account history, the type of transaction, and the branch you visit.

Requirements

Bank of America typically requires the following before they will provide a medallion stamp:

Existing account relationship. You must be a Bank of America customer. Walk-in requests from non-customers are not accepted.

Account history. Most branches require that your account has been open for at least six months. If you recently opened an account, you may be turned away.

In-person visit. Medallion stamps are not available online or by phone. You must visit a branch in person, and not all branches have a trained medallion officer on staff.

Appointment. Many branches require you to schedule an appointment in advance. Availability can be limited, sometimes weeks out.

Transaction limits. Bank of America sets limits on the dollar value of securities they will guarantee. If your transaction exceeds their internal threshold, they may decline.

Supported transaction types. Straightforward individual account transfers are the most likely to be approved. Estates, trusts, corporate entities, and power of attorney situations may be declined due to the additional liability involved.

Common Reasons for Rejection

Even if you meet the basic requirements, Bank of America may still decline your request:

  • Your account is too new (less than six months)
  • The transaction value exceeds their internal limit
  • The transfer involves an estate, trust, or corporate entity
  • The branch does not have a trained medallion officer available
  • The documents are incomplete or unfamiliar to the branch staff
  • You are requesting a stamp for a transaction at another institution

These rejections are not personal. They reflect the bank’s internal risk policies, which prioritize limiting liability over customer convenience.

Processing Time

If Bank of America agrees to provide your medallion stamp, expect the following timeline:

  • Scheduling an appointment: 3-10 business days
  • Branch visit and document review: 30-60 minutes
  • Stamp applied: Same day if everything is in order
  • Total elapsed time: 1-3 weeks from first call to stamp in hand

If documents are missing or the branch needs additional review, the timeline extends further.

When to Use Bank of America

If you have a long-standing Bank of America account, the transaction is straightforward (individual account, moderate value), and you have a branch nearby with a medallion officer available, it may be worth trying your bank first. The service is free for qualifying customers.

When to Use an Alternative

If any of the following apply, an online service may be the faster and more reliable path:

  • Your account is less than six months old
  • The transaction involves an estate, trust, or corporate entity
  • Your branch does not have a medallion officer
  • The transaction value exceeds the branch’s limit
  • You have already been declined
  • You need the stamp on a specific timeline

eSignature Guarantee was built for exactly these situations. We are a STAMP-participating institution that handles all transaction types, with no account history requirement and no branch visit needed. Stamps start at $300, with processing typically within 5 business days.
