What the sources say about these ties
- Mars, Incorporated owns
- Wikipedia names Mars Inc. as the producer of the Mars bar since 1932.
Built from the ownership rows on the brand and company pages, each cited where it is recorded. Made in is the country of production on this product's record; the GS1 prefix of a barcode names the issuing organisation, not where the product was made.
About this product
Mars 4 x 51 g is a 204 g multipack of four full-size Mars bars, milk chocolate with soft nougat (32%) and caramel centre (27%), sold under barcode 5000159481090.[1] The pack photographed in 2015 carries a yellow "3+1 free" flash and the British front-of-pack traffic lights, and declares 1890 kJ / 450 kcal per 100 g and 964 kJ / 230 kcal per 51 g bar.[2][3] A roundel beside the barcode reads "Made in Slough, UK", the underside says "Suitable for Vegetarians", and the back carries consumer-care blocks for Great Britain and Ireland.[1] Forrest Mars Sr. first made the bar in Slough in 1932, and Mars, Incorporated still owns it.[4]
The four-pack sits among the Mars family's British multipacks, most of which now hold 39.4 g bars; this one holds the 51 g single-bar size. The company prefix 5000159 belongs to the group's French confectionery company: GS1's list of GDSN member companies carries GLN 5000159000000 against MARS CHOCOLAT FRANCE, since renamed Mars Wrigley Confectionery France.[5]

- The back prints a GB block, "Freepost Mars Consumer Care", the UK number 0845 0450042, www.mars.co.uk and www.marsnutrition.co.uk; the front carries the UK traffic-light panel.[1] United Kingdom Made in United Kingdom
- The same back prints an IRL block, "Mars Ireland, Box 3856, Dublin 4", with the Irish lo-call number 1890 812 315.[1] Ireland Made in United Kingdom

- Identity: 3 / 3 · Name, brand and classification recorded

- British and Irish "3+1 free" four-pack photographed in 2015: nutrient evidence: 16 / 16 · Recorded nutrient rows linked to a source; not the number of nutrients that ought to exist
- identity · stale: The only dated evidence for this barcode is the 2015 pack, best before January 2016. British four-packs are now sold as 4 x 39.4 g under other barcodes (5000159484527, 5000159551823), but no maker page states when this 204 g article was withdrawn, so no status is set.
- markets · unknown: Searched amazon.co.uk on 2026-09-25 through a web search restricted to the site for "Mars 4 x 51g multipack" (the store's own search answered 202/503 to this agent): only the 4 x 39.4 g multipack B01MTN9PBV and 24- and 48-bar cases of the 51 g single were found, no listing of this 204 g four-pack.
- markets · unknown: Searched amazon.ie on 2026-09-25 for "Mars 4 x 51g", "Mars" and 5000159481090: no listing of this four-pack; the brand search shows the 51 g single, 32- and 40-bar cases, a 5 x 45 g and a 10 x 45 g multipack.
- markets · unknown: A web search for the barcode 5000159481090 on 2026-09-25 found no retailer listing that prints it; a Tesco "Mars Ice Cream 4 x 51g" is an ice-cream article, not this pack.
