Unified English Braille was developed by the International Council on English Braille to unify the braille codes used among English-speaking countries and to unify the braille symbols used in literary, mathematics and computing contexts. It was ratified in 2004 and is now used in many countries around the world, including Australia, Botswana, Canada, Fiji, Ghana, India, Ireland, Kiribati, Malaysia, Myanmar, Namibia, Nepal, New Zealand, Nigeria, Papua New Guinea, the Philipines, Singapore, South Africa, South Korea, Tonga, the United Kingdom, the United States of America, Vanuatu, Vietnam and Zimbabwe. ICEB continues to monitor the use of UEB and clarify or review its symbols and rules as necessary.
The Rules of Unified English Braille is the definitive UEB Rulebook produced by ICEB. Hard copies are available for purchase from RNIB in print and braille at an affordable price. The electronic files are available below for free download and can be printed or embossed for personal use.
The PDF version is designed for printing. See:

Refer to: Section 13, Foreign Language for more guidance.
(October 8, 2019)
The rule is simplified, removing the concepts of “nonspecific” and “predominant” quotes; the importance of the apostrophe in braille is emphasized; there is an expanded section on avoiding ambiguity; and a section is added to give guidance for software developers. There are several new examples.
The new rules can be downloaded below:
Rules of UEB section 7.6 Quotation marks, apostrophe (PDF) - recommended for print readers
Rules of UEB section 7.6 Quotation marks, apostrophe (BRF) - recommended for use with a refreshable braille display
Rules of UEB section 7.6 Quotation marks, apostrophe (Word) - available for use with a screen reader
(July 12, 2022)
The rules have been modified to allow a medial capitals indicator or terminator in longer words containing shortforms which meet specific criteria. The rules relating to avoiding confusion with shortforms have been rewritten to give greater clarity.
The updated rules including the above changes can be downloaded from:

Added words:
(March 26, 2015) under "said" the word unsaid, under "paid" the word unrepaid
(April 24, 2020) under "blind" the word DeafBlind. Note the specific capitalisation.
(May 15, 2021) under "after" the words aftermentioned and aftertheater, under "before" the word beforementioned and under "must" the word mustardy.
(July 12, 2022) the Shortforms List has been consolidated and the entries under each shortform are now strictly alphabetical. The rules for list construction have been clarified and updated to give the rule for the addition of specific words with an interior indicator.

This guidelines document was first produced in October 2008 by the Maths Focus Group, a subgroup of the former UEB Rules Committee during the UEB development phase. The purpose of this document was to give transcribers enough information and examples to produce Mathematics, Science and Computer notation in Unified English Braille.
In August 2014, a new version was produced to correct errors in the first edition. Hard copies of the 2014 version are available for purchase from RNIB in print and
braille.
Electronic versions are available for free download in print or braille:

Technical Material 2014 (PDF format)

Material 2014 (BRF [formatted braille] format)
For those who already have copies of the October 2008 edition, errata
are available in print (5 pages) and braille (7 pages):
Errata GTM 2014 (pdf format)

The Guidelines for Technical Material are currently under revision and will be released in sections for immediate use. Changes in the use of technical symbols that have been approved by the ICEB Executive are also listed below.
In all files, each math example is followed by a verbalization enclosed in quotation marks. Print readers are advised to use the PDF file because many versions of Word will not properly show the math symbols. The Word file is accessible for those who wish to use a screen reader. A braille display will provide optimum reading.
Approved October 2018. This is the first completed section of the revised Guidelines for Technical Material (GTM).

The triple vertical bar ⦀ (U+2AF4, U+2980 or U+2AFC in print) is a sign of comparison meaning is similar to, as in same shape but different size. Its UEB symbol is ⠼⠸⠇ (dots 3456-456-123). It will be used in the same way as other signs of comparison and is included in the revision of 3. Signs of Operation and Comparison.
ICEB has compiled a list of UEB training and resource materials available for free from its member countries.
In April 2004, the ICEB General Assembly declared Unified English Braille to be substantially complete and that it could be recognized as an international standard and considered for adoption by individual countries. The original UEBC Research Project and its subcommittees were disbanded and replaced by a new project charged with oversight over UEB, including its further development.
After official adoption in five countries, the ICEB Executive, at its July 2010 meeting, determined that the development phase was complete and replaced the development project with a UEB Maintenance Committee. UEB has now been adopted in all seven member countries of the ICEB.
Some of the documents pertinent to the research phase of the project, as listed in UEBC Research Project Information -- especially the final committee reports presented at the 2004 General Assembly -- are useful as background information as to how UEB was developed and why certain decisions were made. However, the documents listed on this page provide the most up-to-date information about UEB and in particular, the Rulebook should be considered definitive.
