Effective January 19, 2025, the NMC and RECs will exclusively accept user fee payments via the USCG Merchant Mariner User Fee Payment Page on Pay.gov. Pay.gov, a secure service provided by the United States Department of the Treasury, offers a reliable platform for making payments. Accepted payment methods on Pay.gov include credit cards, debit cards, and bank account routing numbers.
Please take note that as of January 19, 2025, the NMC and RECs will no longer accept any other forms of payment, such as cash, checks, money orders, or credit cards, regardless of whether they are submitted in person or by mail. Any payments made using methods other than Pay.gov will be returned to the applicant, who will then be required to resubmit the fee payment through Pay.gov.
After successfully paying your fees through Pay.gov, it is essential to print or save your receipt. Attach this receipt to your application before submitting it to the NMC. This process ensures a smooth and efficient handling of your application.
