- Avoid literal translation as 'знак личности'. 'Опознавательный знак', 'символ идентичности', or simply 'символ' are often closer. For the mathematical sign, use 'знак равенства'.
Common Mistakes
- Using it as a synonym for 'signature' (e.g., 'Put your identity sign here' is incorrect). Confusing it with 'identification sign' which is more about simple labelling.
