About Marquis Securities, Inc.

Marquis Securities, Inc. was a U.S. broker-dealer organized as a corporation in Oklahoma in 1983 and registered with FINRA from June 7, 1985 to June 4, 1987. As a broker-dealer, it was authorized to sell certain securities products, notably tax shelters or limited partnerships in primary distributions, to individual and institutional investors. The firm’s main office used a 405 area code, indicating an Oklahoma City–area base of operations, and it functioned as a relatively small regional securities firm rather than a large national brand.([files.brokercheck.finra.org](https://files.brokercheck.finra.org/firm/firm_15675.pdf))

A card charge labeled "MARQUIS SEC" or "MARQUIS SEC MARQUIS SEC" would most logically refer to a transaction with Marquis Securities, Inc. (or a closely related entity using the same processing description), for example the purchase of a securities product, an advisory or placement fee, or a transaction-related charge in connection with brokerage activity. However, because Marquis Securities, Inc. is long defunct as a FINRA-registered broker-dealer, any present‑day card transaction with this descriptor could also reflect legacy billing descriptors retained by a successor entity, a back‑office processor, or a coding error by your card issuer.

To verify or resolve questions about this charge, start by checking any brokerage account statements, trade confirmations, or offering documents from the time period around the transaction to see if Marquis Securities or a similarly named firm appears as broker, dealer, or selling group participant. If you cannot match the charge to a known investment transaction, contact your card issuer’s fraud or disputes department and ask them to research the underlying merchant ID and acquirer; they can determine whether this is tied to an active business or a miscoded transaction and can initiate a dispute if needed. Given that Marquis Securities, Inc. is no longer an active FINRA member, you are unlikely to find a working company phone number or website, so your primary recourse is through your bank/card issuer and any intermediary brokerage firm you actually do business with.

Frequently Asked Questions

Is Marquis Securities, Inc. still an active broker-dealer?

No. According to FINRA BrokerCheck, Marquis Securities, Inc. was registered as a broker-dealer from June 7, 1985 until June 4, 1987, and is no longer registered with FINRA or active as a broker-dealer. Any current card charge with "MARQUIS SEC" in the descriptor may instead reflect outdated merchant coding or a successor/related entity using the old name.

What kinds of products did Marquis Securities, Inc. handle when it was active?

Regulatory filings show that Marquis Securities, Inc. reported conducting one line of business: selling tax shelters or limited partnerships in primary distributions, rather than a broad retail brokerage offering. This means charges historically associated with the firm would most likely have related to investments in limited partnership or tax‑shelter‑type offerings rather than routine stock trades.

Why would a modern card statement still show a charge from "MARQUIS SEC" if the firm is defunct?

Some merchant descriptors are legacy strings that persist in payment processors’ systems even after a firm closes or changes names. A present‑day transaction coded as "MARQUIS SEC" might be routed through an old merchant ID, a successor entity that never updated its descriptor, or could be a miscoded charge. Your card issuer can see the underlying merchant ID and acquirer data to clarify the true current merchant.

How can I confirm whether a "MARQUIS SEC MARQUIS SEC" charge is related to one of my investment accounts?

Compare the date and amount of the charge to any investment activity you made around that time—such as subscribing to a limited partnership, making an alternative investment, or paying an advisory or placement fee. Then check your brokerage statements or offering documents for the name Marquis Securities or a similar entity. If there is no match, contact your broker or financial advisor to see if they used any third‑party broker-dealer or placement agent that might bill under this descriptor.

What should I do if I don’t recognize a charge labeled "MARQUIS SEC"?

First, rule out any legitimate investment transactions by checking your brokerage and retirement account records. If you still do not recognize the charge, call the number on the back of your card and ask your issuer’s disputes/fraud team to research the merchant details behind the transaction. Explain that Marquis Securities, Inc. is not an active broker-dealer and that you are concerned about potential miscoding or fraud; they can open a formal dispute or issue a new card if warranted.

Can I contact Marquis Securities, Inc. directly about a billing issue?

In practice, no. Marquis Securities, Inc. is no longer a FINRA-registered firm and does not appear to maintain a current public website or customer service contact. If your card shows a "MARQUIS SEC" charge, your best path is to work through your bank/card issuer and, if applicable, any current brokerage firm you actually use, rather than attempting to locate Marquis Securities itself.

Could a "MARQUIS SEC" descriptor indicate an SEC (Securities and Exchange Commission) fee rather than this firm?

While the term "SEC" often brings the Securities and Exchange Commission to mind, card merchant descriptors that look like "MARQUIS SEC" typically refer to a private firm’s legal name (here, Marquis Securities, Inc.), not a government fee. Government regulators generally do not appear as card merchants. If you suspect the fee relates to a regulatory filing or government payment, verify it through the relevant portal (e.g., your broker’s SEC/FINRA fee disclosures) and with your card issuer.
