After enrolling in E-Bill Express, can I still make payments outside of E-Bill Express, for example mailing in a check?

Yes, you can still make payments to the Port of Seattle outside of E-Bill Express. However, you will not benefit from real-time payment tracking on your E-Bill Express online account.

If your E-Bill is in invoice format, you will see payments made outside of E-Bill Express posted to your account in 2 to 3 business day, as “Paid Other” icon for fully paid E-Bill (see picture above). If your E-Bill is in statement format, you will see payments made outside of E-Bill Express posted to your account in your next month statement.

The following are other payment options outside of E-Bill Express:

Pay with a check by mail

(Please include your remittance slip and write the customer number on your check)

Pay by ACH/wire
