    OP, if you’re not in a country with 9 digit phone numbers, then it’s almost certainly a spoofed typo in the CID field. (which can be easily spoofed just by settings on phones or whatever system is being used.)

    If you’re in a country with a 9 digit… well. it’s probably still spoofed.

    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

        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.

    I mean I’ve been getting spam sms texts from email addresses lately so I assume it’s complete phone anarchy now in these late days

    Likely a fake one.

    You don’t have to have a valid caller id when calling someone. Telcos track call data with other fields.

    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.

        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.

              Because the people wanted it that way

              Haha, love when people decide to just cowboy shit up their way. I’m sure they had reasons, but that’s still just awesome.

              The US didn’t (still doesn’t) use area codes for local calls between landlines (by definition, calls in the same area code are considered local). The reason the area code is important in places like Montreal (large cities) is the number of subscribers. Seven digits gets you 1 less than 10 million numbers.

              Though I suspect the original reason was performance on old mechanical switches (which were still in use into the 2000’s in some US cities). I’ve been in them and those switches are nuts, and crazy loud. If you can route calls to a new switch just using the area code, you don’t have to wait for 6 digits - just start routing after 3, and the new switches will handle the rest. Sort of a load balancing for switching, and would make calls faster - you could bounce the call out of the switching center sooner, especially in areas before tone dialing was a thing (again, mechanical switching was tied to “dialing”, tone became a thing with electronic/digital switches.)

              I don’t know this is what they did, I’m just guessing.

    Probably spoofed, but that doesn’t necessarily make it meaningless. If you convert numbers to letters per the telephone code, and treat 1 as a space or similar punctuation. It might resolve to KISH NORM. Is that phrase meaningful to you? Do you know anyone who would spoof a callerid to send you that message?

    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.
