# Master Names lookup

> Search Cadmus Master Names when adding a person to a call

# Master Names lookup

Cadmus keeps a **Master Names** index for your organization so you can look up people when adding them to a call. Search uses Cadmus data only — it does **not** depend on Oasis being online.

## What you can do

1. Open **Add person** on a new or existing call.
2. Use **Master name lookup**.
3. Enter at least two characters of first or last name (or both).
4. Select a result to fill name, DOB, sex (Gender), and related fields when known.

Lookup returns the **top 5** matches and is designed to complete quickly (typically under 2 seconds). There is no “load more” in the dispatcher dialog — refine the name spelling if the person is not listed.

## What you will see

Results can include:

* Name and middle name
* Date of birth
* Sex (applied to Gender on the person when you select a match)
* SSN (full or masked, based on your permissions)
* Driver’s license and state when known
* City / last known location
* Last seen information

People with the same name are listed separately when Cadmus treats them as different identities (for example different SSNs or licenses).

## SSN display

* If you have permission to view full SSN, the complete number can appear on the result.
* Otherwise you see a masked value such as `***-**-6789`.
* Full SSN searches and views are audited. Cadmus never puts full SSNs in ordinary application logs.

## Oasis

If your agency also uses Oasis, Cadmus can receive Oasis names in the background. Oasis being down does **not** turn off Master Name search. An Oasis ID on a result is optional metadata only.

## Mobile MDT

Officers on the mobile app use the same Cadmus-only Master Name search (top 5) when adding a person to a call. Selecting a match can fill Gender from sex on the Master Name.

## Notes

* Adding or updating a person on a call may update the Master Names index shortly afterward (asynchronous).
* Ambiguous matches are not automatically merged.
* Master Names are shared across agencies in your organization.

## Photos when applying a Master Name

After you select a match from Master Name lookup, a **confirm** step shows any attached photos as thumbnails. Tap a thumbnail to enlarge it, then choose **Use this name** to apply.
