Built-in Identifier Changelog

May 21, 2025

Identifiers in domains is released as GA and these identifier updates are coupled with that release.

Improvements

The following identifiers have been improved to better match their intended data patterns. These updates have only been made to the built-in reference identifiers. If these are already in your domains, they will remain there as domain-specific identifiers with the previous pattern. If you want to add these improved identifiers to your domain, edit the name because identifier names must be unique within each domain.

• NAICS_CODE: Detects strings consistent with North American Industry Classification System (NAICS). A two-digit number represents a basic sector and each preceding digit represents a more specific sub sector with a maximum of six digits.

• SEC_STOCK_TICKER: Matches strings consistent with the stock tickers recognized by the U.S. Securities and Exchange Commission (SEC).
