Why would moving require a new provider/number? Are plans/numbers not portable in Europe?
In the USA, the number reflects the area it was issued. So my phone number matches suburban DC. If I move to California, everybody would know I lived in DC in the past. Kind of odd, I guess, but is a leftover from when cell homes didn’t exist and then when numbers weren’t portable across providers.

They are portable in Europe (I said that in the second part of my comment), but it seemed like they weren’t in the US, because otherwise, the post is a bit strange. The author just tried every number from his area code to find the owner, when it is possible/likely that the owner has a completely different area code. That’s why I thought it might be that the current number always reflects the actual area code.
You're not misunderstanding anything, it was just a bit lucky that the person had their phone number issued in that city. If they moved, they'd take the number with them and this story wouldn't have worked out.
Ah, Americans don’t move around much. At least not any more. Can’t find the figure right now, but an astonishing % live within 10 minutes or so of wherever they grew up.
But that's exactly what they are saying. Numbers are just ported over to a different provider, so there's literally no certainty you can even pinpoint the provider they are using from a number. The prefix belonged to a provider, but you can move numbers as you move providers.
When I first got my plan / phone on the US east coast I was given the option to pick a number from anywhere in the country. I went with a fulsom county CA number and its come in really handy. I know to screen incoming calls that have the fulsom area code (always spam) and numbers that have the local area code where I live are actually legit.
In the UK cell numbers start with 07 and landline numbers start with 01. And there is no region encoded in a cell number, but landline numbers begin with an area code.
Not all the landline numbers start with 01, all the big cities and urban areas got moved into 02 to make space decades ago when there was concern we might run out of space.
Also, 03 is guaranteed to cost the same as 02 but has no specific geographic link, so it's often used for helplines, customer service, that sort of thing, and for people who want to have a landline (or multiple landlines) but do not want to reveal their location.
04, 05 and 06 are part of that roped off space we reserved in expectation of a need that's now unlikely to ever materialise, oh well. In the era when it was conceived people thought "Internet shopping" was a ludicrous idea and still imagined "Video calls" would be a thing you'd do as a telephone call somewhow - so what did they know.
07 as you said is where non-geographic mobiles live, as well as some other services at similar price points
08 is "free" or sometimes revenue sharing prefixes and the 09 prefix is where "premium" services live, you know "Chat live now to singles in your area".
