Add support for Eircodes (Ireland's Postal Code system)
Irish Eircode support is required in Waze. Unlilke a lot of postcode systems, Irish Eircodes are unique codes that match to an exact building/address. https://www.eircode.ie/benefits/overview
I am constantly getting issues reported by users of the below:
Search for an address by its house number, you get correctly routed to the correct road as we have added house numbers.
Search for the eircode, Waze pulls the coordinates from Google and routes to the nearest segment, so many times, this is the incorrect road, a lot of the time it routes users to roads behind the address beause I assume it's technically closer to the coordinates Google provided for the eircode.
We need someway, as editors, to be able to link eircodes to segments, similar to house numbers so that Waze can know to route to the same segment the house number is linked to.
For further clarification, there seems to be confusion around Irish Eircodes. Let me lay out how important they are. If I need to give someone my address, I give them my Eircode, not my address. The Eircode will bring them right to my address. So when people are using Eircodes and they are routing to incorrect roads, and different roads to the address, it's a major issue for the reliability of Waze. How can you trust Waze to bring you to the correct location if it depends on knowing that Eircodes could bring you to the wrong place.

As the majority of addresses in Ireland don’t even have a house number and street name the Eircode is the only way to navigate to them. This makes this a critical requirement in my opinion.

This is important for navigation in Ireland. When I get somebody to come to my house (such as a plumber), I give them the eircode first and maaaybe the house number and street number second.
This may be an issue in other countries too. I think Singapore has postcodes that are unique to each building (not quite as fine-grained as Ireland, where you can have many eircodes for a building if it has lots of addresses in it (such as an apartment building)
