FINRA Rule 11210

Paragraph (b), Uniform Comparison or Confirmation, requires that a properly executed Uniform Comparison or Confirmation be used for each transaction, with a footnote referencing the Final Report of the Banking and Securities Industry Committee entitled Four Uniform Forms, dated December 22, 1971. 

Paragraph (c) establishes the DK Procedures Using Don't Know Notices on FINRA Form No. 101 — a five-part procedure involving certified mail or messenger delivery, a one-business-day response window, and a default-DK outcome for non-response. 

Paragraph (d) establishes an alternative DK Procedure Using Other Forms of Notice — an eight-part procedure that may be used in place of paragraph (c), built around FINRA Rule 11220's trade-identifying information requirements and any communications medium providing delivery and receipt verification. 

Supplementary Material .01 sets forth the Uniform Comparison Form itself. FINRA Rule 11210 was most recently amended by SR-FINRA-2023-017 effective May 28, 2024 — the T+1 settlement cycle conformity amendment that also amended FINRA Rules 11140 and 11150 discussed earlier in this dictionary — with a prior T+2-era amendment through SR-FINRA-2016-047 effective September 5, 2017, and an extensive earlier amendment history dating to February 9, 1968. Four selected notices are associated — 84-44, 10-49, 17-19, and 24-04.

FINRA Rule 11210 sits within the 11200 Comparisons or Confirmations and Don't Know Notices subsection of the 11000 Uniform Practice Code as its first substantive rule, immediately following FINRA Rule 11200's series marker and immediately preceding FINRA Rule 11220's description of securities framework.

FINRA Rule 11210(a): The Same-Day Comparison or Confirmation Requirement

FINRA Rule 11210(a)(1) establishes the rule's foundational obligation in a single sentence — each party to a transaction shall send a Uniform Comparison or Confirmation of same by the end of the day on the trade date. This same-day requirement means that the documentary memorialization of a trade's terms is not deferred to some later point in the settlement process — it occurs on the trade date itself, by both parties independently, each sending its own Uniform Comparison or Confirmation reflecting its understanding of the transaction's terms.

FINRA Rule 11210(a)(2) then establishes what happens with these independently-sent documents — comparisons or confirmations shall be compared upon receipt to ascertain whether any discrepancies exist. If discrepancies do exist, a corrected Uniform Comparison or Confirmation shall be sent by the party in error. This comparison-upon-receipt obligation is the operational heart of the entire comparison and confirmation process — each party, upon receiving the counterparty's Uniform Comparison or Confirmation, checks it against its own records to identify any discrepancies in the trade's terms as recorded by each side. Where a discrepancy exists, the party in error — the party whose records do not match the actual agreed terms of the transaction — must send a corrected Uniform Comparison or Confirmation.

The party in error formulation places the burden of correction on whichever party's records were incorrect, rather than on whichever party happened to identify the discrepancy first. This allocation reflects a sensible principle — the discrepancy-identification process is a check on accuracy for both parties simultaneously, and the corrective obligation falls on whoever's records actually departed from the agreed terms, regardless of which party's comparison or confirmation document first revealed the mismatch.

FINRA Rule 11210(a)(3) establishes the categorical exclusion discussed in this dictionary's FINRA Rule 11200 entry — this Rule shall not be applicable to transactions which clear through the National Securities Clearing Corporation or other clearing organizations registered under the Exchange Act. This exclusion confirms that FINRA Rule 11210's same-day comparison and confirmation requirements, discrepancy-correction obligations, and Don't Know procedures apply only to the category of over-the-counter transactions that fall outside NSCC's and other registered clearing agencies' automated comparison and confirmation processing — consistent with the broader FINRA Rule 11100(a)(1) clearing-agency carve-out for the Uniform Practice Code as a whole.

FINRA Rule 11210(b): The Uniform Comparison or Confirmation Document Itself

FINRA Rule 11210(b) establishes the documentary mandate underlying the entire rule — a properly executed Uniform Comparison or Confirmation must be used for each transaction. The footnote to this provision identifies the document's origin — specifications for use of the Uniform Comparison are contained in the Final Report of the Banking and Securities Industry Committee entitled Four Uniform Forms, dated December 22, 1971.

This 1971 origin places the Uniform Comparison or Confirmation among the oldest standardized documentary frameworks in the entire Uniform Practice Code — predating even FINRA Rule 11110's 1968 UPC Committee establishment by only a few years, and reflecting an early industry-wide standardization effort. The Banking and Securities Industry Committee's Four Uniform Forms report apparently established not only the Uniform Comparison but a small family of related standardized documents — a framework whose influence persists in FINRA Rule 11100(d)'s requirement that the CUSIP number appear on the Uniform Transfer Instruction Form, Uniform Delivery Ticket, and Uniform Comparison or Confirmation, all three of which appear to trace to this same 1971 standardization effort.

Supplementary Material .01 sets forth the Uniform Comparison Form itself — confirmed from the FINRA.org page as a structured form containing fields for the member's name and address, telephone number, originator number, transaction number, trade capacity, settlement type, trade date, settlement date, identification number, contra party clearing house number, special delivery instructions, quantity, CUSIP number, security description, price, and net amount, with a reserved section for the user's money detail calculations. The form's structure directly embodies FINRA Rule 11100(d)'s CUSIP requirement — the CUSIP number field is a core element of the form's identification fields, ensuring that every Uniform Comparison generated under FINRA Rule 11210 carries the CUSIP number that FINRA Rule 11100(d) mandates.

FINRA Rule 11210(c): The Don't Know Notice Procedure Using FINRA Form No. 101

FINRA Rule 11210(c) establishes the formal Don't Know Notice procedure — the procedure invoked when a party to a transaction sends a comparison or confirmation of a trade, but does not receive a comparison or confirmation or a signed DK, from the contra-member by the end of the day on the trade date of the transaction. This is the scenario this dictionary's FINRA Rule 11200 entry identified as the trigger for the Don't Know Notice framework — a party has done its part by sending its own Uniform Comparison or Confirmation, but has received nothing back from the counterparty at all, neither a matching or discrepant comparison or confirmation nor even an affirmative DK.

Paragraph (c)(1) establishes the initiating step — the confirming member shall send by certified mail, return receipt requested, or messenger, a Don't Know Notice on the form prescribed by FINRA — identified in the paragraph (c) heading as FINRA Form No. 101 — to the contra-member in accordance with the directions contained thereon. The provision then establishes a detailed evidentiary chain depending on the delivery method: if sent by certified mail, the returned signed receipt must be retained by the confirming member and attached to the fourth copy of the Don't Know Notice; if delivered by messenger, the fourth copy must immediately be dated and manually receipted by, and imprinted with the firm stamp of, the contra-member, returned to the messenger, and thereafter retained by the confirming member. This multi-copy, signature-and-stamp evidentiary framework reflects the rule's 1968-era origins in a paper-based documentary environment, where establishing a verifiable chain of delivery and receipt required physical signatures, firm stamps, and retained receipts rather than electronic timestamps.

Paragraph (c)(2) establishes the contra-member's response framework. Subparagraph (A) gives the contra-member one business day after the notice is received to either confirm or DK the transaction. Subparagraph (B) addresses a mail response — the second copy of the Don't Know Notice is executed and sent back to the confirming broker by certified mail, return receipt requested, clearly indicating whether the contra-member confirms or DKs the transaction, with the returned signed receipt retained by the contra-member. Subparagraph (C) addresses a messenger response — the contra-member returns the second and third copies of the notice indicating its confirm-or-DK decision, with the third copy dated and manually receipted by the confirming broker and immediately returned to the messenger, then retained by the contra-member.

Paragraph (c)(3) establishes the critical default-DK consequence — if the confirming member does not receive a response from the contra-member by the close of one business day after receipt by the confirming member of the fourth copy of the Don't Know Notice if delivered by messenger, or the post office receipt if delivered by mail, such shall constitute a DK and the confirming member shall have no further liability for the trade. This default-DK provision is the procedure's ultimate resolution mechanism for non-response — silence from the contra-member, beyond the specified window, is deemed a DK as a matter of rule, with the consequence that the confirming member's liability for the trade ends. This default-DK outcome is precisely the kind of DK that FINRA Rule 11190(b)(1) authorizes a member to close-out without further notice once the contract has been submitted to and processed through a reconfirmation and pricing service.

Paragraph (c)(4) establishes signature and authorization requirements — all Don't Know Notices sent pursuant to paragraph (c) must be manually signed by a person authorized to pursue further discussions in respect to the transaction on behalf of the signing member, with the manual signature receipt and firm stamp requirements for hand-delivered copies confirmed in paragraphs (c)(1) and (c)(2)(C).

Paragraph (c)(5) addresses the form itself — the Don't Know Notice form may be ordered through any office of FINRA, and if the official form is not used, the form which is used must conform in every respect to the official form. This conformity requirement ensures that even members who do not use FINRA's own printed form must replicate its structure and content exactly, preserving the procedure's evidentiary and informational integrity regardless of which specific physical form a member uses.

FINRA Rule 11210(d): The Alternative DK Procedure Using Other Forms of Notice

FINRA Rule 11210(d) establishes an alternative procedure that may be utilized in place of the paragraph (c) procedure — addressing the same triggering scenario but through a more flexible, less form-specific framework better suited to electronic communication methods than paragraph (c)'s certified-mail-and-messenger-centric procedure.

Paragraph (d)(1) establishes the initiating step under this alternative — the confirming member shall provide notice to the contra-member identifying the trade in question by providing the information described in FINRA Rule 11220, with the notice also containing a request for the contra-member to confirm or DK the trade and the name of the individual issuing the notice. This direct cross-reference to FINRA Rule 11220 — the next rule in the 11200 subsection — confirms that the description-of-securities content requirements FINRA Rule 11220 establishes serve double duty: they define what a standard comparison or confirmation must contain, and they also define what information a paragraph (d) Don't Know notice must contain to adequately identify the trade in question.

Paragraphs (d)(2) through (d)(6) establish a symmetric verification framework — the confirming member must record and retain verification of delivery of its paragraph (d)(1) notice; the contra-member, upon receipt, must research the trade in question; the contra-member then sends notice back to confirm or DK the trade, including the name of the individual issuing that responding notice; if the confirming member receives no response by the close of one business day after the contra-member's receipt of the confirming member's notice, this constitutes a DK with no further liability for the confirming member — the same default-DK consequence as paragraph (c)(3); and both the confirming member and the contra-member must record and retain verification of the delivery and receipt of the contra-member's responding notice under paragraph (d)(4).

Paragraph (d)(7) confirms the normal-course outcome when confirmation occurs — if the trade in question is confirmed by the contra-member pursuant to paragraph (d)(4), settlement shall be completed in the normal manner, confirming that the entire Don't Know procedure under paragraph (d) — like paragraph (c) — is fundamentally an exception-handling process; when the contra-member does in fact confirm the trade in response to the notice, the trade simply proceeds to settlement as it would have if the original comparison or confirmation exchange had succeeded without need for any Don't Know notice at all.

Paragraph (d)(8) establishes the defining flexibility of this alternative procedure — notices under this paragraph (d) may be delivered through any communications medium which provides verification of delivery and receipt as required under paragraphs (d)(2) and (d)(6). Unlike paragraph (c)'s specific certified-mail-or-messenger framework with its detailed multi-copy form requirements, paragraph (d) is medium-agnostic — any communications medium that can provide the required verification of delivery and receipt satisfies the rule, which would encompass electronic communication methods such as email or electronic messaging systems that can generate delivery and read receipts, in addition to the traditional certified mail and messenger methods that paragraph (c) specifically contemplates.

The Relationship Between Paragraph (c) and Paragraph (d): Two Procedures, One Trigger, Either Available

FINRA Rule 11210's structure — offering two distinct DK procedures for the identical triggering scenario, with paragraph (d) explicitly available in place of paragraph (c) — reflects an evolutionary accommodation within a single rule. Paragraph (c)'s FINRA Form No. 101 procedure, with its multi-copy forms, certified mail and messenger delivery methods, manual signatures, and firm stamps, reflects the rule's 1968-era origins in a paper-based operational environment. Paragraph (d)'s any communications medium procedure, by contrast, reflects a more modern, technology-neutral approach that accommodates electronic communication methods without requiring the specific multi-copy paper-form infrastructure that paragraph (c) presupposes.

Rather than replacing paragraph (c) entirely when paragraph (d) was added, FINRA Rule 11210 preserves both procedures as alternatives — a member may use either the traditional FINRA Form No. 101 procedure of paragraph (c) or the flexible any-medium procedure of paragraph (d) to address the same underlying Don't Know scenario. This dual-procedure structure gives members operational flexibility to use whichever procedure best fits their own back-office infrastructure and their counterparty's capabilities, while ensuring that both procedures converge on the same fundamental outcomes — a defined response window, a default-DK consequence for non-response that eliminates the confirming member's further liability, and a normal-settlement outcome when the contra-member does confirm.

The Settlement Cycle Amendment History

FINRA Rule 11210's amendment history shows the rule was amended by SR-FINRA-2016-047 effective September 5, 2017 — the same T+2 settlement cycle conformity amendment confirmed in Regulatory Notice 17-19 that amended FINRA Rules 11140 and 11150 — and by SR-FINRA-2023-017 effective May 28, 2024, the T+1 settlement cycle conformity amendment confirmed in Regulatory Notice 24-04 that also amended those same rules, as well as FINRA Rules 11320, 11620, and 11860 among others identified in the Federal Register filing for SR-FINRA-2023-017.

This pattern confirms FINRA Rule 11210's place within the broader family of Uniform Practice Code provisions whose specific timing requirements are calibrated to the standard settlement cycle, and which therefore require coordinated amendment whenever that cycle changes. While the core same-day requirement of FINRA Rule 11210(a)(1) — send a Uniform Comparison or Confirmation by the end of the day on the trade date — does not itself reference the settlement cycle's length, the broader settlement-cycle-dependent provisions throughout the Uniform Practice Code that interact with FINRA Rule 11210's comparison and confirmation framework apparently required corresponding technical or substantive adjustments to FINRA Rule 11210 at each settlement cycle transition, consistent with the comprehensive nature of both the 2017 T+2 and 2024 T+1 amendment packages.

Connection to FINRA Rules 11100, 11190, 11200, 11220, and 11860

FINRA Rule 11210 connects to FINRA Rule 11100(d) — whose CUSIP number requirement for the Uniform Comparison or Confirmation is embodied directly in the Supplementary Material .01 Uniform Comparison Form's structure. It connects to FINRA Rule 11190 — whose mandatory reconfirmation and pricing service participation and DK-based close-out authorization under paragraph (b)(1) operate on contracts that may have first been DK'd through FINRA Rule 11210(c)(3) or (d)(5)'s default-DK provisions and subsequently aged without resolution. It connects to FINRA Rule 11200 as its parent series marker, within which FINRA Rule 11210 is the first of two child rules. It connects directly and by explicit cross-reference to FINRA Rule 11220 — whose description-of-securities content requirements FINRA Rule 11210(d)(1) incorporates for the alternative DK procedure's trade-identifying notice content, and which this dictionary will examine next as the final rule of the 11200 subsection. And it connects to FINRA Rule 11860 — referenced alongside FINRA Rules 11210(a) and 11220 in FINRA Rule 11130(a)(1)'s Standard Form confirmation requirements for when, as and if issued/distributed contracts, confirming that FINRA Rule 11210's general comparison and confirmation framework operates as a foundational layer beneath the specialized confirmation requirements of multiple other Uniform Practice Code provisions.

Examination Relevance and Key Takeaways

FINRA Rule 11210 is tested on the Series 7 and Series 24 examinations as the foundational comparison, confirmation, and Don't Know Notice rule of the Uniform Practice Code — establishing the documentary baseline for every covered over-the-counter transaction and the two alternative procedures for addressing counterparty non-response.

The key points to retain are these: FINRA Rule 11210(a)(1) requires each party to a covered transaction to send a Uniform Comparison or Confirmation by the end of the day on the trade date; FINRA Rule 11210(a)(2) requires comparison upon receipt for discrepancies, with the party in error sending a corrected Uniform Comparison or Confirmation; FINRA Rule 11210(a)(3) excludes transactions clearing through NSCC or other registered clearing agencies, consistent with the broader FINRA Rule 11100(a)(1) carve-out; FINRA Rule 11210(b) mandates use of a properly executed Uniform Comparison or Confirmation, tracing to the 1971 Four Uniform Forms report, with the form itself set forth in Supplementary Material .01 including the CUSIP number field required by FINRA Rule 11100(d); FINRA Rule 11210(c) establishes the formal Don't Know Notice procedure using FINRA Form No. 101 — triggered when a party sends its own comparison or confirmation but receives nothing back by end of trade date — involving certified mail or messenger delivery with detailed multi-copy evidentiary requirements, a one-business-day contra-member response window, and a default-DK outcome eliminating the confirming member's further liability for non-response; FINRA Rule 11210(d) establishes an alternative, medium-agnostic DK procedure usable in place of paragraph (c), built around FINRA Rule 11220's trade-identification content requirements, any communications medium providing delivery and receipt verification, the same one-business-day response window and default-DK consequence, and normal settlement if the contra-member confirms; and the rule was last amended May 28, 2024 through SR-FINRA-2023-017 as part of the T+1 settlement cycle conformity package, with a prior T+2-era amendment effective September 5, 2017 through SR-FINRA-2016-047, and an extensive history dating to February 9, 1968, with four selected notices — 84-44, 10-49, 17-19, and 24-04.
