We issue ISBN numbers and barcodes for publications that will be sold through this office.  You may download the ISBN Barcode Application Form‌.  Completed application forms can be forwarded by email to or by FAX to 01 - 647 6843

Please note that as and from June 1st 2012, Houses of the Oireachtas, as part of a review of its processes removed the requirement for documents laid to have a Parliamentary Number (PRN). As a consequence, the Government Publications Office ceased to issue PRN on behalf of the Houses of the Oireachtas Commission.

Please refer to for further information or contact the Houses of the Oireachtas, Library.

All documents to be sold through the Government Publications Office must include our SALES IMPRINT.  Please download the current version.

Government Publications issues Statutory Instrument (SI) numbers.   These numbers are issued in series in respect of each calendar year.   Most SIs must be laid before the Houses of the Oireachtas.

SIs are managed using a dedicated secure website:   

If you wish to discuss the operation of the website or any other aspect of the SI process, please telephone 01 - 647 6633,  01 - 647 6668 or 01-647 6639.
