- the twenty-ninth distinct semiprime and the fourteenth of the form (2.q).
- the ninth composite number in the 43-aliquot tree. The aliquot sum of 94 is 50 within the aliquot sequence; (94,50,43,1,0).
- the second number in the third triplet of three consecutive distinct semiprimes, 93, 94 and 95
- a 17-gonal number and a nontotient.
- an Erdős–Woods number, since it is possible to find sequences of 94 consecutive integers such that each inner member shares a factor with either the first or the last member.
- a Smith number in decimal.
In computing
The ASCII character set (and, more generally, ISO 646) contains exactly 94 graphic non-whitespace characters, which form a contiguous range of code points. These codes (0x21–0x7E, as corresponding high bit set bytes 0xA1–0xFE) also used in various multi-byte encoding schemes for languages of East Asia, such as ISO 2022, EUC and GB 2312. For this reason, code pages of 94<sup>2</sup> and even 94<sup>3</sup> code points were common in East Asia in 1980s–1990s.
In other fields
