Standards Under Public Review
The following standards are currently open under ANSI’s public review period. Please check back regularly as items are constantly updated.
The following Public Review announcement will appear as shown below in ANSI Standards Action 8/14/2026
Comment Deadline: September 28, 2026
X9.152-202x, PKI Lifecycle Management (new standard)
This standard addresses the management and security of asymmetric keys for protecting financial information and other associated data independent of the asymmetric algorithm, schemes or public key cryptography protocol. An asymmetric key pair consists of a mathematically related private key and public key that are jointly created using an asymmetric key generation algorithm. Only the public key (often encapsulated within an X.509 certificate issued by a certification authority) is distributed to the relying party. The corresponding private key must be retained by the originating party. Key management lifecycle for symmetric keys are well known, practiced, and documented in ANSI X9.24 and NIST 800-57 but far less so for asymmetric key pairs, including the private key and public key certificates issued from a public key infrastructure (PKI).
X9.100-20-2021 (R202x), Magnetic Ink Character Recognition: Printing MICR Characters (reaffirmation of ANSI X9.100-20-2021)
This standard specifies the shape, dimensions, magnetic signal level, and tolerances for the E-13B characters which include ten numeral characters and four special symbol characters. When these E-13B font characters are printed in magnetic ink and used for the purpose of character recognition, the printed characters become magnetic ink character recognition, or what is commonly referred to as MICR. Also described are the various known types of printing defects and other printing considerations, together with the tolerances permitted.
X9.100-120-2015 (R202x), Bank Deposit Tickets (reaffirmation of ANSI X9.100-120-2015 (R2021))
This standard specifies certain deposit ticket parameters to aid in the processing of personal size and business size deposit tickets through conventional bank deposit and imaging processes. While this standard does not establish a specific design, orientation and layout for bank deposit tickets, it does provide specifications for a range within which key design elements shall be placed. Other bank specific information is excluded from this standard. This standard will improve the understanding of deposit tickets by providing background information that may be valuable in designing deposit tickets. It is hoped that the use of this standard will result in greater uniformity in several aspects of deposit ticket design that will improve the processing and handling of deposit tickets throughout the entire check processing system
The purpose of this standard is to provide the financial industry with a format necessary to perform electronic check exchange (ECE), with or without images. The format supports forward presentment, posting, return notification, and return requests, as well as existing customer information reporting products. The standard also supports multiple check clearing alternatives, e.g., bank-to-bank, bank-to-switch.
X9.129-2020 (R202x), Legal Orders Exchange, Version 3 (reaffirmation of ANSI X9.129-2020)
In today’s environment legal orders are generated in a large number of formats by a variety of different government agencies. These documents are then mailed to the bank for processing. When the bank receives the requests (mail, fax, spreadsheet) the process for fulfilling them is highly manual, which is time consuming and can be prone to errors, and there are limited areas where automation is applied. In most cases, the basic types of information, required for processing, are the same across the different request types. By creating a set of standards for electronic file formats for the different request types, benefits will be realized by both the requester and the receiver through automation of the process.
X9.100-187-2021 (R202x), Electronic Exchange of Check and Image Data – Domestic (reaffirmation of ANSI X9.100-187-2021)
The purpose of this standard is to provide the financial industry with a format necessary to perform electronic check exchange (ECE), with or without images. The format supports forward presentment, posting, return notification, and return requests, as well as existing customer information reporting products. The standard also supports multiple check clearing alternatives, e.g., bank-to-bank, bank-to-switch.
X9.100-160-1-2021 (R202x), Magnetic Ink Printing (MICR) Part 1: Placement and Location (reaffirmation of ANSI X9.100-160-1-2021)
Part 1 of this standard covers only design considerations that apply to placement and location of magnetic ink printing on checks, drafts, and other documents intended for automated processing among depository institutions. Other types of documents such as internal control forms are not covered. A complete understanding of MICR printing requires reference to other standards and technical guidelines listed in Clause 2.
X9.100-10-2021 (R202x), Paper for MICR Documents (reaffirmation of ANSI X9.100-10-2021)
This standard establishes paper specifications for the MICR documents that are used in the US Payments System. While checks, substitute checks (IRDs) and deposit tickets are the primary documents considered in these specifications, users of MICR/OCR E-13B font readers will be well served by applying these specifications to internal documents, when intended for use in reader/sorters.

X9.84-202X, Biometric Information Management & Security for the Financial Services Industry (revision of ANSI X9.84-2018)
This standard describes the security framework for using biometrics for authentication of individuals in financial services. It introduces the types of biometric technologies and addresses issues concerning their application. This standard also describes the architectures for implementation, specifies the minimum security requirements for effective management, and provides control objectives and recommendations suitable for use by a professional practitioner.
