The flag in a white border occasionally seen on merchant ships was sometimes referred to as the '''Pilot Jack'''. It can be traced back to 1823 when it was created as a signal flag, but not intended as a civil jack. A book{{clarify |reason=What book? |date=September 2012}} issued to British [[consul (representative)|consul]]s in 1855 states that the white bordered Union Flag is to be hoisted for a pilot. Although there was some ambiguity regarding the legality of it being flown for any other purpose on civilian vessels, its use as an ensign or jack was established well in advance of the 1864 Act that designated the [[Red Ensign]] for merchant shipping. In 1970, the white-bordered Union Flag ceased to be the signal for a pilot, but references to it as national colours were not removed from the current Merchant Shipping Act and it was legally interpreted as a flag that could be flown on a merchant ship, as a jack if desired. This status was confirmed to an extent by the Merchant Shipping (Registration, etc.) Act 1993 and the consolidating Merchant Shipping Act 1995 which, in Section 4, Subsection 1, prohibits the use of any distinctive national colours or those used or resembling flags or pendants on Her Majesty's Ships, "except the [[Red Ensign]], the Union flag (commonly known as the Union Jack) with a white border", and some other exceptions permitted elsewhere in the Acts. However, Section 2 regards the "British flag", and states that "The flag which every British ship is entitled to fly is the Red Ensign (without any defacement or modification) and, subject to (a warrant from Her Majesty or from the Secretary of State, or an Order of Council from her Majesty regarding a defaced [[Red Ensign]]), no other colours."<ref>{{cite web |url=http://www.legislation.gov.uk/ukpga/1995/21/data.pdf |title=Merchant Shipping Act 1995 |website=UK Public General Acts |publisher=[[The National Archives (United Kingdom)|The National Archives]] |date=19 July 1995 |access-date=17 January 2010}}</ref> The Flag Institute listed the white bordered Union Flag as "Civil Jack".<ref name="british-flag-protocol" />

From 1884 until 1928, the [[Royal Indian Marine]] flew a modified Union Jack bordered with blue as its jack. From 11 November 1928 until its dissolution in 1947, it substituted the [[Blue Ensign]] defaced with the [[Flags of British India#Emblem|Star of India emblem]] as jack and flew the British [[White ensign]] as ensign.<ref>{{Cite web |title=

The [[Hudson's Bay Company]] (HBC) was one of a few non-government institutions using the Union Jack in part of the flag. HBC rival [[North West Company]] had a similar flag as well. The HBC Red Ensign is no longer in use in 1965 and replaced with a corporate flag featuring the company's coat of arms.
[[File:British Empire flag (1930).svg|thumb|The unofficial [[British Empire flag]] incorporated dominion symbols]]
An unofficial flag for the British Empire was created around 1910 due to a belief that the Union Jack itself no longer sufficiently represented dominions such as Canada, which were beginning to adopt their own unique symbols. The flag was similar in design to a White Ensign, which features the Union Jack in the canton. In the other quadrants were the coats of arms of Canada, Australia, and South Africa. The four stars forming [[Crux|the Crux]] over Saint George's Cross represented New Zealand, and the Star of India was featured prominently in the middle. Civilians often flew Empire flags for patriotic events such as coronations, [[Commonwealth Day|Empire Day]], and the [[British Empire Exhibition]].<ref name=":1">{{Cite web |last=Kelly |first=Ralph |date=8 August 2017 |title=A flag for the Empire |url=https://www.flaginstitute.org/wp/wp-content/uploads/2022/11/ICV27-B8-Kelly.pdf |url-status=live |archive-url=https://web.archive.org/web/20230813214957/https://www.flaginstitute.org/wp/wp-content/uploads/2022/11/ICV27-B8-Kelly.pdf |archive-date=13 August 2023 |access-date=13 August 2023 |website=The Flag Institute |page=}}</ref> It is still flown on special occasions at the [[Dangarsleigh War Memorial]].<ref>{{Cite news |last=Ingall |first=Jennifer |date=4 June 2021 |title=Why the Dangarsleigh war memorial flies the Empire flag and what it means to the community |work=ABC News |url=https://www.abc.net.au/news/2021-06-05/dangarsleigh-memorial-celebrates-century-flying-empire-flag/100180732 |url-status=live |access-date=13 August 2023 |archive-url=https://web.archive.org/web/20230813215116/https://www.abc.net.au/news/2021-06-05/dangarsleigh-memorial-celebrates-century-flying-empire-flag/100180732 |archive-date=13 August 2023}}</ref>

The Union Jack is the third [[quartering (heraldry)|quarter]] of the 1939 [[coat of arms of Alabama]], which is used on the flag of the governor of Alabama, representing British sovereignty over the state prior to 1783. The version used is the modern flag, whereas the 1707 flag would have been used in colonial Alabama.

In the former International Settlement of [[Kulangsu]] the Kulangsu Municipal Police had a badge contained multiple flags, including the Union Flag. The badge was incorporated into their police flag.<ref>{{FOTW|id=cn-kul|title=International Settlement of Kulangsu (Gulangyu, China)}}</ref>
