Why would you not put a stamp on it like any other letter you post? A county council is not part of An Post so even they pay for postage. Even post to An Post needs a stamp on it-unless the dept you are writing to has a freepost address.
Driver licencing and motor tax use freepost licences. If you write 'Eire' or 'Freepost' on the envelope, it will be ok. Usually, they enclose a prepaid envelope with the reminder/renewal notice.
What about mail to Members of Oireachtas? Does one need a stamp to send them a letter/ postcard?
I know that all post sent to 'Revenue' is FREEPOST, but if one puts a stamp on the envelope; no one is going to complain.
Please can anyone clarify about mail to TD's or Senators. [They all get a certain amount of Envelopes with green Harp logo on it and it doesnt require a postage stamp].
