So lets’s start with answering one by one
1. What is Person Number and Worker Number in Oracle Fusion HCM
Person Number – Person number is generated when the person is created in the system. It is unique id of any person record . It is created at Enterprise level.
We can say, person number is the base feature in the enterprise. Each person has one person record. Person Number can be allocated automatically or manually based on Person generation method you select.
Worker Number – By default, worker numbers are not used. We can also enable worker numbers at the enterprise and legal-employer levels using 1) Manage Enterprise HCM Information and 2) Manage Legal Entity HCM Information tasks in the Setup and Maintenance work area respectively.
If we enable worker numbers, each employee and contingent worker work relationship must have a worker number. And in case if we don’t enable worker numbers, they can’t be used.
When we enable the worker number at both the enterprise and legal employer levels, then the setting at the legal employer takes precedence. Worker numbers can be generated in two ways 1) manually 2) automatically.
In case if we select automatic worker-number generation, numbers can be allocated from either an enterprise sequence or a legal employer sequence. and if you use a legal-employer sequence, worker numbers are not guaranteed to be unique in the enterprise.
When you use a legal-employer sequence, the worker number doesn’t change if you rehire in the same legal employer. However, the worker number changes if you rehire in a different legal employer or globally transfer to a different legal employer.
If we use an enterprise sequence, the worker number does not change when you:
- Rehire in the same legal employer.
- Rehire in a different legal employer.
- Globally transfer to a different legal employer.

2. How to change person number of an employee in Oracle Fusion HCM
You can’t change the person number all the time. We can only change it if your enterprise Person Number Generation Method is Manual.
So we will see how to change the person number when the it is Manual. First you need to check Person Number Generation Method .
Navigation -> Setup and Maintenance -> Search for Manage Enterprise HCM Information

On the Manage Enterprise HCM Information page, scroll down to “Enterprise Information” section

Now Navigate to My Client Groups -> Person Management -> Search the person -> then go to “Person” under Personal and Employment

After that by default Person Information page will open first. On this page, you can see Person Number section and edit button on the right hand side. Click on edit and change the Person Number but make sure the person number you are entering is unique and not allocated to any other employee. After entering the unique person number click on Submit.
In case, if you enter the person number which is already allocated to any other employee, you will get an error as Person Number with this value already exists. Enter a unique value.
3. Difference between person number and worker number in Fusion HCM
Person Number : is the person record’s unique ID when you create the record and is required and valid throughout the Enterprise and these Numbers can be allocated automatically or manually based on person generation method you select.
When an employee joins the firm, the person history is maintained through out the employee life cycle.
Worker number : The Number identifies employee and contingent worker work relationships and Person with multiple such relationships has multiple worker numbers.
By default, worker numbers are not used. In case if we enable worker numbers, each employee and contingent worker work relationship must have a worker number and If we don’t enable worker numbers, they can’t be used.
This number changes if you rehire in a different legal employer or globally transfer to a different legal employer. Hence, the Number identifies employee and contingent worker work relationships also person with multiple such relationships has multiple worker numbers.
