Sailors seeking career assistance will soon receive greater support from Navy Personnel Command's (NPC) Customer Service Center (CSC) as it transitions to round-the-clock service beginning Sept. 24. The CSC is integrating with My Navy Portal to become the My Navy Career Center (MNCC) contact center, available 24/7. The My Navy Portal is Tier Zero. If you need greater support than what is available through self-service in our ever-expanding suite of services in My Navy Portal, then you contact the MNCC contact center, which is Tier One. As feedback is received from Sailors and more insight gained as to what services Sailors need, more capability will be added to the MNCC contact center.
