You can now pay for parking through the Reykjavík Parking Service on Reykjavík City's website. This is a service that supplements meters at the location and the use of apps. No fee is charged when payment is made online.
You pay in advance for parking and the price depends on the type of tariff zone you park in.
You can also now pay parking citations online. However, appeals for a refund of charges are made through Ísland.is and more detailed instructions are on the Reykjavík Parking Service's website.
