Eircode mis-routing has been identified as an issue since the code was 1st launched in 2014. However, the number of reports of this happening in recent months is becoming alarming. The cause of mis-routing is explained in the post here Essentially Eircode has no link or relationship with the road from which access to the property is gained and the relationship is required for a navigation system (all including Google maps) to provide accurate routing to the address.

Some mis-routing reports are related to an ambulance being sent in the wrong direction and to the wrong road and, in all cases where mis-routing has been identified, the potential for an ambulance to be delayed arriving to assist patients is a real possibility.

In emergency response, every delay is potentially life threatening. Some other reports of ambulances being mis-routed are shown here

Minister Richard Bruton TD was advised of this problem in writing during 2019 and was also asked on several occasions to amend the Eircode ambulance advert to ensure the public are advised to check their code before they have to rely on it in an emergency. Unfortunately, to date the Minister has chosen not to act.

Mis-routing is also an issue for couriers & other deliveries and if your courier is saying that you cannot be found, then mis-routing could be the cause.

Everyone should check their code and do it for those who can't by following the guide here

 There is no systematic process for checking Eircodes either when they are allocated to a building by computer or after they have been delivered in the door by a postman/woman. The tweet in the above image is one of many reports that verify this.
If you do not check your Eircode (and do it for those that cant) nobody will and, if not used for other purposes then, it could mis-route an ambulance the very first time it is used. There are several examples of Eircode mis-routing shown below.
