For an adult whose surname is Cox, I would start with 考 Kǎo. It keeps the opening of 考克斯 Kǎokèsī, an established transcription, and a separate published dictionary identifies 考 as a surname pronounced kǎo. 寇 Kòu is a useful comparison if you already use the attested spelling 寇克斯 or prefer its vowel and falling tone. Neither short form preserves all the sound of Cox. 1, 2, 3
A full transcription and a chosen Chinese surname serve different purposes. 考克斯 represents the foreign surname as a whole. 考 is a decision to use a one-character surname before a Chinese given name. You can keep Cox alongside either form when colleagues need to connect your identities.
Start with the actual transcription
The National Academy for Educational Research's English surname table gives Cox—考克斯. Elsewhere in the same handbook, particular music entries use 寇克斯, including Cox, David Vassal and Cox, Jean. The contrast is useful evidence of published practice, rather than a contest in which one spelling must invalidate the other. These people provide transcription examples only; their work or reputation is not a reason for you to choose their character. 1
For a new choice with no established Chinese usage, 考 is the more direct starting point in that general table. If you already sign your name 寇克斯, keeping 寇 avoids changing the first character simply to match someone else's preference. An adult's existing usage deserves attention before a name is redesigned.
What Kǎo keeps, and what it loses
Start with your own family pronunciation of Cox, especially if you are comparing an American pronunciation with a British one. The published British-word example /kɒks/ cited in the earlier comparison is not a universal surname reading. Mandarin kǎo uses an ao vowel sequence and a third tone; it loses the final /ks/ when 克斯 is removed. 寇 Kòu changes that Mandarin vowel to ou and the tone to fourth. Neither choice captures the full English ending, and neither is made exact by your nationality. 4
The surname evidence is independent of that sound resemblance. The third edition of the Chinese–Japanese dictionary reproduced by Kotobank places an explicit surname sense under kǎo. Its entry also records ordinary meanings concerning examinations, investigation and a deceased father. Those are lexical meanings, not descriptions of a person bearing the surname. You need not pretend that 考 only has a flattering meaning. 2
For a practical introduction, 我姓考，考试的考。Wǒ xìng Kǎo, kǎoshì de kǎo. identifies the written character through a familiar word. The phrase does not mean that your name translates as “exam” or that you are being assigned an academic personality. 考 is the same character in simplified and traditional writing.
Why 寇 is a genuine alternative
寇 Kòu is independently recorded as a surname under the fourth tone. Compared with 考, it changes ao to ou and the tone from third to fourth. Both omit the English ending. It is therefore an alternative adaptation, not an objectively exact rendering of Cox. 3
寇 also has ordinary meanings connected with raiders or intruders. That does not turn a surname bearer into one, just as an English surname does not normally function as a literal character assessment. Still, if you are choosing a new name and dislike the association, that is a reasonable personal reason to prefer 考. The character 寇 also stays unchanged between simplified and traditional scripts.
The choice is concrete: 考 follows the general transcription table; 寇 follows another attested spelling and offers a different vowel and tone. A list of pleasant-sounding unrelated surnames would not improve that comparison.
Do not build a rowing or rooster ancestry from the spelling
The ordinary English word cox means a rowing-boat coxswain, but a dictionary definition of that word does not establish the origin of the surname. The surname dictionary reproduced by FamilySearch gives more than one route for Cox, including English connections with Cocke and Cook and different explanations in other languages. 4, 5, 5.1, 5.2, 5.3, 5.4, 5.5
These multiple origins do not support one literal Chinese translation of Cox. The documented 考克斯 and 寇克斯 forms give you a clearer basis for the two short surnames compared here.
Make the decision in your full name
Try 考 and 寇 before the actual given name you plan to use. Say the complete name in an introduction, then ask a Mandarin speaker to repeat it and identify the character after you explain it. A tone combination that looks attractive in isolation may feel different in a full name.
Choose 考 Kǎo first for continuity with 考克斯; compare 寇 Kòu for an established 寇克斯 spelling or a preferred ou sound. Keep the complete transcription if recognising Cox is more important than shortening it.
