Can I renew my USCG license early?

Updated: Jun 9

Yes, it's encouraged. You can renew up to 8 months before your MMC is going to expire with zero penalty.





When will my new MMC be issued?

When you renew within the 8 month window, the Coast Guard will post-date your new license. This means that the issue date of the new MMC will be the day following the date of expiration of the current MMC, but no more than 8 months in the future.


The new credential will not be valid until the issue date listed on the new MMC. Mariners must continue to carry their current credential until that date.


Mariners are required to return expired or otherwise invalid credentials to the NMC. When the current credential expires, it should be mailed to the NMC.


Can the issue date be earlier?

Mariners may choose to have the new MMC issued immediately. This will result in the new MMC being dated when issued instead of post-dated for the day after the current MMC expires. This option may be necessary for mariners who's company does not allow them to sail under an MMC that is expiring soon.
