If you add up all the digits, it sums up to 46, which sums up to 10, which sums up 1, and that's exactly how many shits you should give about this

No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

Who are you, so wise in the ways of maths?
While applying this technique, the caller may well hang up, so the quandary is solved regardless.
See, this is a type of proof that many mathematicians overlook preferring to opt instead for Proof by Contradiction or Proof by Induction. If they just sit and applied Proof by Waiting, they could solve their theorems with 100x less the effort.
This morning I proved Pythagoras's Theorem by employing Proof by Waiting. I waited exactly 5 seconds, and in that time found that it had been proved by a simple online search. Mathemeticians are idiots.
Bringing back the absurdum to Reduction Ad Absurdum.
Likely a fake one.
You don't have to have a valid caller id when calling someone. Telcos track call data with other fields.
A spoofed one.
My guess is some kind of spoofer shenanigans
If you still have a land line you can dial locally without even an area code. This worked in most countries. Some mobile phone networks kept this tradition although in a weirder way: you could dial locally when physically located in those areas, and your phone would display the area code you were in on the its standby screen. Which worked as long as you weren’t on a border between cells and it picked the wrong one.
Over time this went away.
I don’t think this is what you have experienced, but it was a nice thing that blurred the lines between land line and mobile phones for a little while, and I think it’s interesting.
where has 9 digit locals?
Brazil has a stupid numbering system for phones, now. Instead of having three digits area codes and several area codes for highly populated areas, they have two digits area codes and nine digits phone numbers. (But it’s not the case here, here is a scam caller)
But, why?
Seriously, if you understand how this came to be, I'm curious. I'd think they implemented land lines using extant hardware systems of the era, and the number structure surely was well established by that point?
Now I'm off to go down a rabbit hole of telecom implementations worldwide.
I don't know exactly why. A quick search told me that "because the people wanted that way". In Brazil, we don't use the area code for local calls, so, if they created a new area code for the same city (like we have in Montreal, the 514 and the 438), it would cause confusion.
thanks! i was sure there had to be somewhere
My guess would be a (spam) call center landline.
In Peru (and some islands in the Pacific as well IIRC), some regions have nine digit numbering plans. This may have been a call from one of those areas. More likely its spam.
Honestly, I don't know what kind of number that is either. I usually get calls with country codes that make it easier to guess. How about searching for the number in an identification service to give you a clue as to who that is exactly?
