Variation Selectors Supplement is a Unicode block containing additional variation selectors beyond those found in the Variation Selectors block.
These combining characters are named variation selector-17 (for U+E0100) through to variation selector-256 (U+E01EF), abbreviated VS17 – VS256.
Ideographic Variation Sequences
{{as of|2017|12|12}}, VS17 (U+E0100) to VS48 (U+E011F) are used in ideographic variation sequences in the Unicode Ideographic Variation Database (IVD).{{Cite web | url=https://www.unicode.org/reports/tr37/ | title=UTS #37, Unicode Ideographic Variation Database | publisher=Unicode Consortium }} These selectors are known as Ideographic Variation Selectors (IVS). They are not listed in the list of standardized variation sequence, instead they are listed in another Ideographic Variation Database.{{cite web |url=https://www.unicode.org/ivd/ |title=Ideographic Variation Database |institution=Unicode Consortium}}

The following IVS collections are currently registered in the IVD:

| {{flag|Japan}} | {{code|Adobe-Japan1}} | CID-keyed Japanese OpenType fonts. Defines at least one sequence for every Japanese kanji from the {{code|Adobe-Japan1}} collection present in Unicode, even for those with only one glyph, both as future-proofing and to allow that (Japan-region) glyph to be uniquely referenced.{{cite web |url=https://www.unicode.org/ivd/pri/pri108/ |title=PRI 108: Combined registration of the Adobe-Japan1 collection and of sequences in that collection |last1=Lunde |first1=Ken |author-link1=Ken Lunde |last2=Muller |first2=Eric |year=2017 |publisher=Adobe/Unicode Consortium |quotation=Note that all Adobe-Japan1-6 kanji, except those twenty seven pointed out above, are given IVS assignments, including those that have only one form assigned. This is to ensure that each Adobe-Japan1-6 kanji can be uniquely and explicitly identified without referencing their default (IVS-less) encoding, and because kanji may be added in future Adobe-Japan1 Supplements that may be variants of such kanji.}} | {{#formatdate:2007-12-14}} | {{#formatdate:2022-09-13}} | 14684 | {{plainlist|

Similarly to the Moji Jōhō Kiban's role in Japan, the character repertoire of CNS 11643 (including draft revisions) is used for administrative purposes in Taiwan.{{cite web |url=https://www.unicode.org/irg/docs/n2486-T_2021_sub.pdf |title=TCA’s submission for the CJK extension IRG Working Set 2021 |author=Taipei Computer Association |id=ISO/IEC JTC1/SC2/WG2/IRG N2486 |date=2021-05-07}} In some cases, multiple of these correspond to a single Unicode character.{{cite web |url=https://www.unicode.org/irg/docs/n2546-TSourceGlyphIssues.pdf#page=3 |title=4.

However, the Taipei Computer Association, which represents the interests of Taiwan in the Ideographic Research Group, has been evaluating the feasibility of registering an additional IVD collection in the future.{{cite web |url=https://www.unicode.org/irg/docs/n2502-TCAActivityReport.pdf |title=Activity Report from TCA |author=Taipei Computer Association |date=2021-09-10 |id=ISO/IEC JTC1/SC2/WG2/IRG N2502}}
In Mainland China, the Culture and Art Publishing House has been collecting variant forms required for digitisation of intangible cultural heritage in databases and e-books, and has expressed the intent to register an IVD collection once this is finalised.{{cite web |url=https://www.unicode.org/irg/docs/n2796-CAAPH-IVD.pdf |title=Request for review and endorsement of a preliminary version of the CAAPH IVD collection |first=Eiso |last=Chan |id=ISO/IEC JTC1/SC2/WG2/IRG N2796 |date=2025-02-27}}
