SSN Instructions and Information

It has come to our attention that some CNA students have been submitted by training programs and have actually registered for the certification exam with invalid social security numbers. The students in question have used a nine-digit number beginning with the number “9”, which is actually an Individual Taxpayer Identification Number or “ITIN”. According to the Administrative Code, individuals who are placed on the Registry MUST have a Social Security Number. An ITIN is NOT a Social Security Number, which will cause them to NOT be placed on the Health Care Worker Registry and, therefore, will prevent them from working as a CNA.

We are taking steps to have the online registration program modified to prevent the Program Coordinators from entering invalid social security numbers and to prevent someone from registering for testing. Until this is set up, we are appealing to all training programs to assist us with identifying invalid social security numbers during the online registration process.
The guidelines for invalid social security numbers can be found at–IssuingSSNs.pdf. Information concerning ITINs may be found at

Briefly social security numbers are invalid if they:
• begin with the number “9”.
• begin with the number “666” in positions 1 – 3.
• begin with the number “000” in positions 1 – 3.
• contain the number “00” in positions 4 – 5.
• contain the number “0000” in positions 6 – 9.

As a Program Coordinator, it is vital that you take the necessary steps to ensure that individuals have valid social security numbers prior to beginning your training program. In order to verify this information, it will be necessary for the training program to see the individual’s social security card prior to being admitted to the program.

While an individual may complete a training program without a valid social security number, it is not in their best interest to do so as they will NOT be allowed to test, nor will they be put on the Registry until such time as they obtain a social security number. As you should be aware, students who successfully complete a training program have 12 (twelve) months from the date of program completion in which to take the CNA exam.
