Demand for copies of NI birth ceftificates has reached such a level that it's disrupting normal activities in the General Register Office in Northern Ireland.

"Due to a high demand for birth certificates, in recent weeks, the General Register Office search room in Oxford House has not been taking any new bookings in order to allow GRO staff to deal with the volume of orders." - Spokesman

This demand has been caused by the Brexit vote. People want to be able to keep their right to freedom of movement within the EU. One way to do this is to get dual nationality with another country that is going to remain part of the EU. For a lot of British people, obtaining an Irish passport is an ideal way to achieve this.

One of the ways people can get an Irish Passport is by showing they were born in Northern Ireland before 2005; or if after 1st Jan 2005, that they also have an Irish parent who fulfils certain residency requirements. The exact requirements for Irish citizenship are here.

So why would Ireland freely offer Irish citizenship to people from Northern Ireland? Because all the major political parties in Ireland support the idea of the eventual reunification Ireland into one state. If you support reunification, then you would naturally support the idea of all the current citizens of Northern Ireland becoming Irish citizens as well. Hence people born in NI can easily gain Irish citizenship.

So how do you show if you are born in NI? With a copy of your birth certificate of course. Hence people have been asking for copies so they support their passport applications. Exactly how many applications there have been, isn't clear at the moment until the Passport Office's stats for July come out. But it's widely expected that there will be a spike in people applying from NI and GB. Certainly the demand for copies of NI birth certificates has been enough to disrupt Northern Ireland's General Register Office, which handles the documents for all births, deaths and marriages in NI.
