A public announcement from the NMC:

The USCG National Maritime Center is experiencing problems with our phone system, which is impacting calls coming into the Mariner Information Call Center.

We are working with the Coast Guard’s Electronic Support Detachment and the telephone company to correct this problem as fast as possible. Until the problem is resolved, callers may experience a busy signal or longer than normal wait times while calling the 1-888-IASKNMC phone number.

If you have problems contacting the Call Center you may still contact us via e-mail at IASKNMC@USCG.MIL or by calling one of the 17 Regional Exam Centers.

Contact information for the Regional Exam Centers can be found at
