Medallion Signature Guarantee Locations in San Antonio, TX
Directory of 149 verified physical bank and credit union branches in San Antonio participating in statutory STAMP and SEMP signature guarantee programs. Check institution rules, account seasoning requirements, and branch contact information below.
Crucial Instructions Before Visiting Any Branch in San Antonio:
1. Never pre-sign documents: A Medallion Guarantee legally certifies that the guarantor witnessed your physical signature live. If you sign at home, the officer must refuse your form.
2. Call ahead for guarantor presence: Medallion stamps are not held by regular tellers. Only designated branch managers or licensed AVPs possess stamp certification. Always call the branch telephone number below before traveling to confirm the guarantor is on-site today.
3. Verify account seasoning: If using Bank of America or Wells Fargo, your account must have been active for at least 6 months. Non-customers will be turned away.

Frequently Asked Questions in San Antonio, TX
Where can I get a Medallion Signature Guarantee in San Antonio?+
In San Antonio, there are 149 verified physical branches participating in STAMP or SEMP guarantee programs across 12 financial institutions (including JPMorgan Chase Bank, Bank of America, Wells Fargo Bank). You must visit a branch where you maintain an active account in good standing.
Can I get a stamp at a San Antonio bank without having an account?+
No. Commercial banks in San Antonio strictly refuse non-customers because affixing a Medallion stamp incurs unconditional legal liability up to \$500,000+ if the signature is fraudulent. You must be an established customer.
Can a Notary Public in San Antonio stamp my securities transfer?+
No. Stock transfer agents (Computershare, EQ, American Stock Transfer) will reject paperwork certified with a standard notary seal. A notary only verifies identity with minimal liability, whereas a Medallion Signature Guarantee is backed by a commercial surety bond.
What documents do I need to bring to a San Antonio branch?+
You must bring: (1) Government photo ID; (2) The completely filled-out but UNSIGNED stock transfer form; (3) An official brokerage or transfer agent statement dated within 60 days showing proof of ownership and share valuation; (4) Certified legal documents (Death Certificate, Letters Testamentary) if handling an estate transfer.
