* In Belgium (Dutch), Brazil, Denmark, Germany, Greece, Indonesia, Italy, Netherlands, Portugal, Romania, Russia, Slovenia, Sweden and much of Europe, "{{gaps|1|234|567,89}}" or "1.234.567,89" are seen. In [[handwriting]], "1˙234˙567,89" is also seen, but never in Belgium, Brazil, Denmark, Estonia, Germany, the Netherlands, Portugal, Romania, Russia, Slovenia or Sweden. In Italy, a straight apostrophe ({{code|'}}) is also used in handwriting: "1'234'567,89". In the Netherlands and Dutch-speaking Belgium, points are used as thousands separators, and is preferred for currency values, but the space is recommended by some style guides, mostly in technical writing.<ref>{{cite web|url=http://taaladvies.net/taal/advies/vraag/1/10000000_10_000_000/|title=10.000.000&nbsp;/&nbsp;10&nbsp;000&nbsp;000|author=Taalunieversum|access-date=1 September 2017}}</ref>
* In Estonia, currency numbers often use a dot ({{code|.}}) as the decimal separator, and a space as a thousands separator. This is most visible on shopping receipts and in documents that also use other numbers with decimals, such as measurements. This practice is used to better distinguish between prices and other values with decimals. An older convention uses dots to separate thousands (with commas for decimals) – this older practice makes it easier to avoid word breaks with larger numbers.
* Historically, in Germany and Austria, thousands separators were occasionally denoted by alternating uses of commas and points, e.g. "1.234,567.890,12" (or "1.234,567.890·12" in Austo-Hungary and Austria prior to 1938)<ref>{{cite web |last=Röll |title=Union Pacific-Eisenbahn |work=Enzyklopädie des Eisenbahnwesens |url=http://www.zeno.org/Roell-1912/A/Union+Pacific-Eisenbahn |access-date=26 August 2014}}, entry "Union Pacific-Eisenbahn", largest numbers in table</ref><ref>{{cite web |last=Röll |title=Bilanz |work=Enzyklopädie des Eisenbahnwesens |url=http://www.zeno.org/Roell-1912/A/Bilanz |access-date=26 August 2014}}, entry "Bilanz", sums in last table</ref><ref>{{Internet Archive|id=bub_gb_VnswAQAAMAAJ|name=Österreichischer eisenbahnzeitung Zeitschrift des Klub österreichischer eisenbahn un schiffsfahrtbeamten...|page=259}}</ref> for "eine Milliarde 234 Millionen ...", but this isn't seen today and contemporary German readers would require an explanation to understand it.
* In Switzerland, there are two styles. Currency values use an apostrophe ({{code|'}}) as a thousands separator along with a dot ({{code|.}}) as the decimal separator, like "1'234'567.89". For other values, the SI-style "{{gaps|1|234|567,89}}" is used, with a comma ({{code|,}}) as the decimal separator. The apostrophe is also the most common thousands separator for non-currency values, like "1'234'567,89".
* In Ireland, Israel, Japan, [[Korea]] (both), Malaysia, the Philippines, Singapore, Taiwan, Thailand, the United Kingdom, and the United States, "1,234,567.89" or "1,234,567·89" are seen. However, the latter is generally only found in older, [[Manuscript|handwritten]] documents. 
* For English-speaking regions of Canada, there are two styles. The preferred style for currency values is "$10,000.00", while the preferred style for numeric values is "{{gaps|1|234|567.89}}". However, commas are also sometimes used, despite no longer being taught in school or used in official publications.{{Citation needed|date=September 2016}}
* The [[International System of Units]] (SI) uses the following two styles: "{{gaps|1|234|567.89}}" and "{{gaps|1|234|567,89}}". In their own publications, a dot ({{code|.}}) is used in the English version, while a comma ({{code|,}}) is used in the official French version.
* In [[Sweden]], the a colon ({{code|:}}) is sometimes used as the decimal separator for currency values, like "{{nobr|1 234 567:89}}".
* In China, commas and spaces are used to mark digit groups, since dots are used as decimal separators. There is no universal convention on digit grouping, however, so both thousands grouping and no digit grouping can be found. Japan and Taiwan are similar, although, when grouping by myriads, [[kanji|{{translit|ja|kanji}}]] or [[Chinese characters]] are frequently used as separators, like the following: "1億2345万6789" or "1億2345萬6789" {{xref|(see [[Japanese numerals]] and [[Chinese numerals]])}}. Commas are used when grouping by thousands.
* In [[India]], which uses the [[Indian numbering system]], commas ({{code|,}}) are used at the thousands, [[lakh|{{translit|hi|lakh}}]], and [[crore|{{translit|hi|crore}}]] levels. For example, {{nobr|10 million}} ({{nobr|1 {{translit|hi|crore}}}}) would be written "1,00,00,000", while {{nobr|100 thousand}} ({{nobr|1 {{translit|hi|lakh}}}}) would be written "1,00,000". In [[Pakistan]], there is a greater tendency to use the standard western system, but the Indian numbering system is used when conducting business in [[Urdu]].
