How To Find Mobile Number Location

To build apps that make use of phone numbers, it's often crucial to verify that the user owns a number. Doing this can be tricky from a UX perspective, not least in understanding phone number formats in different locales, but also in providing a verification mechanism that isn't cumbersome or using intrusive device permissions, such as the ability to read all of a user's SMS.

There are many libraries for efficient pre-built phone authentication, such as Firebase Phone Auth, but if you are an advanced developer and need to build this functionality yourself, Google Play Services has two new APIs that help you obtain a user's phone number and verify it via SMS without device permissions: the Phone Selector and SMS Retriever. Apps like Flipkart have seen a 12% increase of success rates in phone number sign-up flows using these methods.

To further state they would leave themselves open to a lawsuit if they did so is even more laughable. As I mentioned they would simply change the policy and state your mobile phone number will be used for whatever new thing they may deem advantageous to Google as Google sure as hell does not have it’s Customers best interest in mind when they do anything. Google among other massive Corporations has been allowed to become a massive monopoly gobbling up more companies in a given year than one company should be allowed to in a lifetime. The next policy change would explain they are now going to share your mobile phone number with other companies that Google deems you might be interested in due to your shopping habits (or an email that was scanned for key words) or whatever other reason they might give.

Let’s look at Google’s history, anytime they want to change what they do with the information one gives them, they just change their Privacy Policy. I know Leo, you are much wiser than I am one it comes to all things computer related, and I totally admit that is 100% true. I also know my email account with Gmail is among one of the oldest as it was a beta deal and I wanted to give the “online” email genre a try. Prior to that I had an e-mail account with my local ISP which was a completely different animal. Gmail/Google has a history of very upset customers due to policy change, merging accounts one does not want merged, and a whole host of other very irritating behavior, and every time one has to weigh the trouble of changing all of one’s contacts, etc. against just doing nothing and let the changes take place. Yes in many cases they gave forewarning of such events, but for you to state quite explicitly that Google will not use ones mobile phone number for anything but proof of identity is foolish.

I have received many annoying sales phone calls from Google advertisers. How did they get my phone number? I am reluctant to give my phone number to businesses. I never know who it’s going to be given to, despite assurances that it won’t be given to anyone. At one time I had an alternate number that I never answered except for account verification. But maintaining that number cost me money. Why should I have to pay to not be disturbed? Leo, do you know any way around this problem? Why can’t an email address be used for verification?
