Parking tag for rental cars

Greetings All,
We are coming to Ireland in July and we are renting a car. I've noticed that Ireland mainly has paid parking. Therefore, I have a couple of questions:
1) Can we purchase a parking tag at the rental agency when we get the car?
2) Should we register online?
3) Should we purchase one in the first place?
All suggestion are welcomed.
Cheers,

Hello Pete,

Thanks for the question!

There are a lot of places indeed where you will be required to pay for parking. There isn't one central place where you can register and pay for all the locations as each individual council or private parking area has its own service.

There are also free locations to park, it really depends on where you will be visiting. We would love to hear what you have added to your itinerary so far?

Martin

Thanks Martin!
Cheers,
Pete
