Found my number on there too even though I've deleted Facebook for at least 5 or 6 years now -_- Not sure when I gave them my number either, I hope it wasn't scraped from someone else's contact list... At least it makes sense why I received a bunch of spam calls over the weekend.

Anyway it's probably good practice to recycle your number every few years, and not use it for 2FA to make switching numbers a lot easier. Who knows what services I'll be locked out of once I change, let's hope not too many.

I can’t imagine telling everyone I know that I’m changing my number every couple years, and I’m not even calling/messaging a lot of people nowadays. I have a family member who did something similar(not on purpose) and I still have 3 of her numbers and still get confused which is the working one.

I had a company phone about 6 or 7 years ago for a company I worked for at the time. When I was on my way out they unilaterally revoked my company-provided cellphone after convincing me I should get rid of my old private number for theirs.

I'll never do that again. It happened shortly after ditching social media and I just about all of my contact info and I haven't been in touch with some old friends because of that since then.

Even if you had the time to transfer your contacts, etc, something will inevitably get missed.

Hell, I've updated family and friends to an email address I've been using for closer to a decade and they still email the old one...

I know exactly what you mean, there's only so many times you can append "New" on the end of a contact name!

A good chunk of people will probably communicate mostly on platforms like WhatsApp/Telegram/Discord/whatever that don't need numbers at all or facilitate switching of numbers without your contacts having to do anything. I don't think that will constitute anywhere near the majority of people across the world though, switching numbers will definitely be a pain for most.

"Anyway it's probably good practice to recycle your number every few years, and not use it for 2FA to make switching numbers a lot easier."

Ironically Twilio of all places forced SMS 2FA on all accounts earlier this year.

As in, one day you could no longer log into your twilio account without giving them a phone number. You are locked out until you do.

Ironic in a few ways ...

First, twilio numbers are not mobile numbers - they are voip numbers - and cannot be used for most 2FA authentication services because they cannot receive messages from short codes. So it's ironic that twilio forces you to use a non-twilio number for their 2FA.

Second, many twilio use-cases (like mine) involve building a twilio infrastructure to replace my existing phones/numbers ... and now that is broken from the bottom up because I have to use a mobile phone with a fixed provider just to use twilio.

The bottom line is: none of this is for me or my safety and security. Twilio has a spam problem and that spam problem is very hard to solve. Forced pairings of physical phones and SIM cards is just a desperate way to throw sand in those gears to slow it down a little bit.

I have had a Twilio account for years, and have always used the proprietary MFA implementation from their Authy app. I don’t remember being forced to switch to SMS MFA.

In my limited experience, I've had more phone spam plus wrong number calls right after changing phone numbers due to the number being recycled.

[hnrodey]

I've had the same phone number for somewhere around 17 years. I kept this number even as I moved across the country (US).

[Cd00d]

I thought this was the norm. I've had the same number for 20 years now, though have moved through many different area codes since. But, I must be the odd one, because I get asked regularly why I have the area code I do, and the answer "because that's where I was living in 2001" doesn't seem satisfactory.

[dunham]

It's kinda nice living in a different area code from my phone. I know that if I get a call from 415, it's spam.

[hyyypr]

I don't recall ever giving my phone number either and my number is detected by HIBP..

Really?

Every phone number is already known to anyone who wants to get it.
