Some confusion exists about the number of professional accounting bodies that use ‘chartered’ in their name. There is no confusion, however, about who was granted the first royal charter by Queen Victoria in 1854: The Society of Accountants in Edinburgh. You can still see the original charter in the website of the Institute of Chartered Accountants of Scotland. [1]
Only a handful of accounting bodies still have a royal charter. Others jumped on the bandwagon ignoring the royalty but keeping the reputation of respectability, ethics and high professional standards. Only the accounting body in the Netherlands now maintains both when they translated their name, Koninklijke Nederlandse Beroepsorganisatie van Accountants (NBA) into The Royal Netherlands Institute of Chartered Accountants. They are both royal and chartered. In the UK, Australia and New Zealand, they are also royal and chartered, but only keep chartered in their names.
But I digress. Wikipedia claim there are 34 accounting bodies with chartered in their name, however they include a doubtful one; a Brussels-based company calling itself the European Institute of Chartered Accountants (EICA). In 2020, the High Court in the UK issued an injunction to ban it from claiming they have any connection to ICAEW, ICAS or Chartered Accountants Ireland.
Wikipedia also forgot to add several other accounting bodies notably Botswana, Cameroon, the Maldives, Suriname and an auditing body: the Institute of Authorized Chartered Auditors of Albania.
To eliminate the confusion I now declare that there are at least 39 chartered accounting bodies worldwide.
