# Built-In Identifier Changelog

## 2025.1

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.

To see more about the specific changes made, see the annotations on the [Built-in identifier reference page](/latest/configuration/manage-data-metadata/data-discovery/reference-guides/improved-pack-built-in-identifier-reference.md).

### New

The following identifiers are newly created to identify common data patterns. Copy these new reference identifiers to any of your domains.

* BELGIUM\_NATIONAL\_REGISTRATION\_NUMBER: Detects numeric strings consistent with Belgium's National Registration Number. Requires 11 characters in the form YY.MM.DD-NNN-XX, where YY.MM.DD corresponds to birth date, NNN is a number, and XX is a checksum digit.
* COUNTRY: Detects strings consistent with the names of all countries in the world. This identifier is case-insensitive.
* FINANCIAL\_INSTITUTIONS: Matches strings consistent with names of financial institutions based on lists provided by the FDIC and OCC, includes alternative names.
* GREAT\_BRITAIN\_DRIVERS\_LICENSE: Previously named `UK_DRIVERS_LICENSE_NUMBER`. Now, renamed because it does not detect license numbers from Northern Ireland.
* ICD\_10\_PCS: Detects strings consistent with procedure codes from the International Statistical Classification of Diseases and Related Health Problems (ICD), as drawn from the Clinical Modification lexicon from 2020.
* 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).
* US\_PERSON\_FULL\_NAME: Detects strings consistent with a person's {first name} space {last name}. Uses the same names from the PERSON\_NAME identifier. This identifier must match at least 20% of the data sampled and is case-insensitive.
* US\_STREET\_ADDRESS: Previously named `STREET_ADDRESS`.

## 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://documentation.immuta.com/latest/configuration/manage-data-metadata/data-discovery/reference-guides/improved-pack-built-in-identifier-reference/built-in-identifier-changelog.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
