# Labels A "Label" in ChainArgos is a wallet or smart contract tag that seeks to identify the individuals, companies, organization, and/or entities operating that wallet or smart contract address. "Labels" can be divided into two major categories: * [Programmatic Labels](/documentation/labels/programmatic-labels.md); and * [Sourced Labels](https://docs.chainargos.com/documentation/info/label/sourced-tags). Addresses typically have more than one "Label" associated with them, and each "Label" is separated by two semicolons: ``` ;; ``` Occasionally, a "Label" where a higher level of precision may be lacking, will be labeled with question marks. A single question mark indicates that there are some doubts as to the precision of the address "Label." ``` ? ``` More speculative address "Labels" are indicated by a series of three question marks. ``` ??? ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
