I absolutely love that the chaos of Ireland's post codes makes it super easy to add or remove addresses with absolutely no fuss, that's amazing
uniqueId for the win
Ireland sometimes doesn't need the Eircode either. The An Post guy is such a boss that I've had mail arrive with just my name on it.
What Grey didn't expand on is that before adopting Eircode in 2015, Ireland didn't really HAVE post codes. So they took a system that sometimes relied on individually named houses in the address (yes, some houses had names instead of street numbers - and I guess some probably still do) and leapfrogged the rest of the world by adopting a 21st century solution. Good job Ireland!
Fun Fact: The U.S. ZIp Code digit 9 actually extends *outside* of the United States, to Palau, Micronesia, and the Marshall Islands. The U.S. took control of these islands from Japan after World War II and even though they're now independent countries they are still served by the U.S. Postal Service and treated as domestic addresses for American shipping.
@DecafPotato compact of free association. The us also handles their security.
welp guess its time to mail something to palau
wait nvm i dont live in the us
Huh, an actual fun fact, that followed the words "Fun Fact". Kudos.
Alright well I guess I'm gonna start writing my +4 on everything now just because it's peak efficient. Thank you Grey, very cool, the post office folks will be very pleased they no longer have to figure out my package routes when the code can do it for them
But, like... different websites give me different +4s for my address! I'm never sure which one is right! :P
@@JetstreamGW Fascinating! Overlapping routes, maybe?
@ I have _no_ idea.
We are SO back.
You were JUST bitching about CGP Grey not posting videos that weren't selling a product, you human integrity void.
@ I asked politely and wearily where the real videos were BEFORE I saw the notification about this premier. I got my answer (and I’m very pleased with it!). So chill, please!
Hey, wait, you were the one who joked to ME that he’s “only making notebooks now.” Why are you coming at me for that? Whatever
@@TitenMakesMusic You were complaining about Grey's output being purely commercial. (You sure as hell weren't "asking politely and wearily" and I was not joking to you -- I was reinforcing your stated fact). I responded that was true. Then you, here, under this video, backpedalled faster than a Trump appointee. I didn't. I agreed that, yes, he was only doing notebook sales videos under that notebook vide. You then commented here -- I mean, it's right FUCKING THERE, dude -- "We are SO back." Again, zero integrity: He's only doing notebook sales videos | WOOO! Videos are back!
One video does not offset an entire year's worth of Grey not posting videos, but the second he made this one, your ass flipped instantly. That's the zero integrity element, champ. It's not tough.
@ You guys are now internet friends.
Mailman (city letter carrier) here, the "new" last 4 on the zip code are useless or more specifically obsolete, they became obsolete when we changed to the DPS (delivery point sequence) system, basically every address on a route has a delivery number, before that the last 4 helped narrow down a neighborhood, apartment complex, or other high volume mail area that extra sorting might help. But with DPS, the auto-sorting machines, and spraying of IMB (Intelligent Mail barcode) on every letter, the ZIP+4 has no purpose and if you look at the Zip+4 lists now, you can see something of time capsule of how routes used to be as the +4 was never updated to reflect route adjustments.
Back in the late 90's-early 00's when we still got video game demos on disc, there were often early game developer websites you could sign up to get free ones sent to you in the mail. They only let you order one per address, but I figured out that you could very lightly tweak or misspell things and the form thought it was a different address. Some of these demos I could resell for a few bucks so I set out to experiment and see out how much I could change my own address and still get the disc successfully. Turns out I could absolutely butcher the street, city, and state and even the house number sometimes and still get it to show up, but if any part of the zip was wrong, game over! Those never arrived
I love the postal service. You should do something about how international mail works. I've always wondered how the delivering postal service is compensated for the mail they deliver for other countries. Are there some sort of international agreements on it? How come usps has a single rate on letters to almost every country in the world? Surely some countries would demand more compensation than others?
Given Japan's street address system. They should probably adopt Ireland's post code.
And then call the result a "zip" code, just to make trouble
This inspired me to check the map of ZIP codes, which reminded me that there are a few _single buildings_ in Manhattan which have their own 5-digit ZIP code, like 10112 (30 Rockefeller Plaza, where SNL is filmed). What I found most fascinating was that none the four largest buildings in Manhattan by square footage (55 Water Street, MetLife, 1WTC, and 111 8th Avenue) have their own five digit ZIP code.
Please, for the love of all that is good: in most (at least many) cases the ZIP+4 uniquely identifies your address. If you’re going to block out your address, also block out at least the plus 4.
As an example, someone shared an envelope, and blacked out their entire address except the ZIP+4, and after looking up that, I knew they lived in apartment number 14, because apartment 13 and 15 both had different ZIP+4s.
And this fact should be fairly clear by the length of the code if you think about it. 5+4=9 digits, which means 10^9 = 1 billion possible ZIP+4 codes. That's enough for 3 per person, and most people a) don't have 3 addresses and b) live with at least one other person. So even after factoring in all the corporate buildings and such which aren't tied to a particular person, it should still be enough for everyone to have a unique ZIP+4.
4:32 hey, that looks like a Dutch postal code... Wait a minute, it IS a dutch postal code!
It is the postal code of the Nederwaard in Kinderdijk. Which has a lot of windmills.
Oh poor Grey... I can only imagine the rabbit hole that you went down to make this video and I love you all the more for it. Thank you again for tackling a complex topic and breaking it down with enough nuance to hint at the reasons for an imperfect system and how it came to be while also explaining it.
7:45 did not foresee this fall 🤣
My big complaint is that I keep trying to do my ZIP+4 only to have web forms refuse to accept the extra four digits because whoever DESIGNED THE ORDER FORM is quite certain a zip code is only 5 digits
Most web forms that accept the +4 will have a separate field for the extra four digits, so that's your cue to grab the +4.
@webbowser8834 I mean I shouldn't be surprised web forms don't accept it, half of them don't accept the city I live in because it has a hyphen
@ oof, that one is much less defensible.
2:48 Unfortunately (according to a quick google search) this is called a "Sectional center facility" (SCF), not a "Sectional facility center".
This, of course, doesn't matter at all.
Don't let him see that, or there wont be a new video for a few years
Scotland has three arms!
Took me a long time to realize the letter is addressed to Christopher Billop from the Staten Island video
I drummed my feet against the floor at a new CGP Grey video and this did not disappoint. I was entranced, I laughed, I cried. It was an epic compressed to 7 minutes. Perfection.
Fun Fact: In Germany, from 1990 onwards, there was a four-digit postcode system. There was a problem: the postcodes often overlapped, for example 2300 was used for Stralsund and Kiel. There was a way to get around this: W (west) and O (east) were written in front of the number. That means O-2300 for Stralsund and W-2300 for Kiel. From October 24, 1991, the board of the German Federal Postal Service (today: Deutsche Post AG, or DHL Group for short) decided on a completely new five-digit system.
As someone who has lived 90% of my life in New Jersey and Massachusetts, I always thought other states were weird for having zip codes that don't start with 0. Now I know the truth
Imagine if every zip code started with a 0.
You'd have to wonder what that 0 was for. What is the government hiding? What happens if you remove the 0 or put a different digit there? Does it get delivered to subterranean lizard people?
was kinda hoping you would go into more countries postal code systems
Great video from famous notebook salesman CGP Grey!
Gotta love the wild world of codes everybody has to live with but nobody understands
CGP GREY IS ALIVE!?
Oh this is awesome.
Ireland is btw killing it
Thanks!
During this dark week where we're hurtling faster than ever towards destruction from an uncaring (and now possibly Chinese) machine god, I did not know that I needed a CGP Grey video on postcodes. But it's exactly what I needed!
Thanks!
Not gonna lie, I was grinning ear to ear when i saw the notification of a new video. :D
Same 😊
Good to see you again !
It has been so long since last CGP Grey upload
When mailing internationally... you probably should include the country. ON THE LAST LINE, below the postal code. Because the US sorters may not know a Canada post code from one in England. If the address ends 'Ontario, CA M5G 1X6', country before the postal code, your package *will* go on a trip to Ontario California.
Same applies to mailing things to the US, the country one line down from the zip - otherwise the sorters may wig out and ship our international mail back to Japan or wherever it came from.
Cheers.
In Germany the purpose of zip codes is in the name. We call them postal guiding codes (Postleitzahl) as it guides the post on how to get to the final post office.
So Ireland's postcodes are a bit like traditional postcodes and Plus codes / OpenLocationCodes combined. Smart!
Yesssssss! TY!
Rejoice! The wanderer has returned! 🍀
Do I smell some Bonnie Bee postal codes in other countries videos popping up soon?
I bet you loved using the new Minnesota flag on the stick figure’s skirt!
Éirinn go Brách!
Rewatching already! Very nais
Postcode went a bit complicated in Germany after reunification, Imagine a country almost doubling in size. To keep most of the old numbering system they basically just added another number in front.
I bet after this video there will be a noticeable uptick in use of the last four digits by folks in the USA
0:22 France is "numeric"! We use 5 digit post codes!! How is this data not known?
Hopefully now we can get an explainer on what caused the delays and can expect more vids in the future! Hope whatever the issue was was transitory and wishing you well, Grey.
For multi-story apartment buildings, Ireland's postal code just gets you to the building, right? You still have to write apartment/unit information on the letter?
There's actually a dotted notation you can append that specifies altitude (in standard potatoes), 4th dimensional offset, and time dilation increment. It's meant to work through a stargate, should any be found.
this is so fascinating omg
I was thinking that Ireland's way might not work the same in Taiwan , we have too many apartments that have hundreds of unit inside.
Just add a geohash for that mathematical perfection.
5:24 I think this is the first time, in a long time, that someone other than Grey spoke more than two sentences with their mouth OPEN
Dear lord Grey is evolving
If you were to send 1000 letters to Irish postcodes, given you restrict it to one postal area in, say, central Cork, how many would be delivered?
1:50 I dont mean to be THAT person, but you forgot 94 lol (only noticed cause I live there)
It was interesting living in Grenada - despite my best efforts I couldn't find a ZIP for that country
You mean the zip code isn't a good way to bundle population statistics based on land proximity? Data shock!
Is my resolution too low, or is the map accidentally orange above the Netherlands?
New grey is not the highlight of my day I was expecting. But it’s sooooo welcome.
I'm becoming a post code perfectionist!!!
Christopher Billopp, a British loyalist who lived on satterlee st on staten island during the US Revolutionary war 🤓
Ohhh billopp is in grey’s video on the race for Staten Island 🤦🏻
UPS still requires the zip code but doesn't use the same sorting centers, yes?
Taking bets on how many people are gonna try sending random letters to the Irish post codes featured [real or not]
I'm one of those weirdos that includes his +4 thank you very much.
The downside to Ireland's method is that if their electronic infrastructure breaks down, the databases become unusable or the automatic sorting machines won't work, then humans are going to have a hell of a time sorting all the mail by hand...
I'm a software engineer and I think it's incredibly dumb to make societal functions so heavily reliant on software that you cannot do the work by hand. Software should serve an assisting function, not be relied upon.
I get what you’re saying but I think there will be bigger issues than sorting mail in that situation.
Yeah, but think what a boon it will be to the print industry to make those address books!
@@rich9684 Not necessarily. It could be the only thing that fails, but the mail still needs to be delivered. The mail should be delivered even if there's a war or blackout. As long as it's not dangerous for the staff to go outside, the mail should be sorted and delivered. A small delay is fine, but you cannot have important societal functions come to a halt because of problems with computers or electricity.
My point is that important functions must have redundancies that allow the work to be done manually. If you build your system in a way that REQUIRES computers to function, then you're building them for total collapse when something goes wrong.
For an analogy: Imagine if car wheels locked up if the engine died. You couldn't roll to the side of the road or even push the car out of the way. You'd come to a complete standstill in the middle of a highway and couldn't do anything about it.
That's why we don't suggest only the Eircode. You should do both :)
CGP Grey in 2025?!
So today we learn that Ireland is based
BABE WAKE UP, NEW CGP GREY VIDEO!!!
Is that the Boulder Dash music?
That's so crazy
1:07 I'm sure this was just for rhyming purposes, but the suggestion that Maryland and West Virginia are in any way part of the south hurts me a little as a native Marylander
Amazing, a video not about flags!
Hitting reverse at zero to hear Grey dropping the beat 🤣 Ery.. Ery.. Ery.. Ery letter!
Neat
Thank you!
Can we have American $5 coins now?
Put Lincoln on them and then let go of the penny.
2 videos in 1 day? Grey, are you OK?
The other one was an ad.
I bet they made it a double whammy so that long-time subscribers wouldn't be upset about waiting for months only for an ad to be the only thing they get.

During ireland explanation, you passed by, an hair away, justifying the use of W3W as destination address. It may not suffice for large buildings with more than 4 families under the same roof, but it would work for most other cases.
😊
I didn't get my email notification!
Update: I got the email after I finished the video 🙂
Did you use +4?
YOUR BACK
Zip codes! (I use postal codes 😔)
Probably helps that Ireland is small. I'm guessing if you tried that in the US, you would get 50 digit postal codes!
Probably not. The first three places allow for 42,875 sorting centres, and the remaining four allow for 1,500,625 addresses near each one. That creates a grand total of 64 billion unique addresses, which the US probably needs what, a few percent of? That's vs Ireland's basically none of. The system scales!
yet still no Indian reservations
Belgian's use zip the word "code's" to 😅
Let’s go
Haters crying about no posts.
We need a new penny video! If anyone can kill the penny (and other useless coins) it’s Trump!
Back in Germany now, but I liked my UK postcode. Never forgot it once: M8 8BS. Mate ate ... bullshirt. :D
And yeah, was basically just one "road", so just the code and my house number would have sufficed.
There was also no name on my door/doorbell/postbox (which is the door, coz ... UK). So you could have written to Ehel at XX M88BS. \o/
Also meant post from former residents would still be delivered ...
