If you have a friend or relative in New York State, sign up for NY Service Center E-ZPass using their New York address. When the account is activated, log in online and change your billing address.
New York Service Center issues tags for MTA, Port Authority, and Thruway Authority. MTA and Thruway tags do not charge a monthly fee (by state law), whereas Port Authority tags do charge the fee (NY State law does not apply to a bi-state agency unless both states agree, and NJ was the very first to start the fees). Their method of assigning tags to an agency is very simple....NY residents get Thruway or MTA tags (depending on upstate or downstate address), while all out of state residents get Port Authority tags.
