I too saw one of these. Very odd since I was expecting a note about a job.

- TedDoesntTalk 4y agoDon’t reply to those SMS. Your geolocation can be derived from your reply, even a STOP or UNSUBSCRIBE reply.
- akouri 4y agoCan you explain how this works if you don't click any links?
- TedDoesntTalk 4y agoI read about it on HN some months ago. I don’t recall if it was in comments or an article. But I read the info and sources and was convinced enough at the time. I’m sorry I didn’t save the original info. I’ll try some googling “geolocation from SMS” and see what I can find.
- daenz 4y agoPresumably if they have the number to text to, they already roughly know the geolocation for most people, through the area code.
- jhugo 4y agoOnly in the US (or whole NANP?) Mobile numbers are non-geographic everywhere else that I know of.
- eru 4y agoWell, depends. For example, Singapore's numbers are 'non-geographic' in that sense. But Singapore itself is small enough.
- elkos 4y agoGreek here, mobile phones are non-geographic but used to be service provider specific, but even this practice isn't applicable due to number portability. Landlines used to be geographic but this isn't relevant any more again new to number portability.
- jhugo 4y agoI mean non-geographic within the country. As far as I know, the US practice of assigning mobile numbers to 'area codes' is unique.
- eru 4y agoYes. I was broadly agreeing with you. Just saying that some countries are small enough that it's essentially the same.
- TedDoesntTalk 4y agoThat’s not what I’m talking about. And since number portability and mobile devices became possible, area codes are mostly irrelevant. For example, I’ve lived 2000 miles from the area code of my phone number for probably 10 years now.
- daenz 4y agoThey're not mostly irrelevant. 72% of Americans live in or close to the city that they grew up in. Area code is remarkably accurate.

- mathrawka 4y agoThat information is completely derived from the phone number.
- iJohnDoe 4y agoYes, would like to learn more as well.

- nl 4y agoCan you provide a pointer showing how this is supposed to work?
