I initially wrote on this submit that we want a standardized method for functions on the Web to seek out out when the earlier person of a given cellphone quantity has stopped utilizing it. I’ve since discovered* that the U.S. Federal Communications Fee (FCC) created the Reassigned Numbers Database, which helps to handle that downside. I’ve up to date this submit to mirror that.
Telephone numbers are fascinating. Yeah, I mentioned it. Significantly—what if I instructed you that the least fascinating factor about cellphone numbers is that they make our cellphone system work? Years from now, when our cellphone system (voice calls and even SMS) turns into completely out of date, I predict we’ll nonetheless depend on cellphone numbers in a method or one other.
Right here’s why I believe these strings of digits are rather a lot cooler than they get credit score for, and the way I believe we should always use them sooner or later.
What I like about cellphone numbers
They’re simple to make use of.
a cellphone quantity once you see one. If you happen to discover a string of digits written on a toilet wall, what it’s, why it’s there, and what to do with it. Telephone numbers are fairly quick, too, when you consider it—quick sufficient that we are able to simply share them with one another and keep in mind them, relative to spelling out a reputation or remembering an e mail handle.
Your cellphone quantity is a common identifier. Telephone numbers are worldwide, and nobody else on the earth can have your quantity however you. When touring from nation to nation, the place one language is fabricated from fully completely different characters than the subsequent, numbers are sometimes best to work with. We are able to take this technique of communication—this least frequent denominator of getting ahold of each other—anyplace on the earth.
They’re distinctive identifiers.
We use numbers to log in to social and messaging apps, and it is a massive purpose why I consider they’re right here for the lengthy haul. WhatsApp is the preferred messaging app on the earth with greater than 2 billion energetic customers, and like these coming in simply behind it (Fb Messenger, WeChat, and Viber), all you want is a cellphone quantity to get began.

Whereas safety might enhance with cellphone quantity authentication, utilizing cellphone numbers as distinctive identifiers tends to be safer than utilizing e mail addresses, which is why I predict we’ll preserve utilizing them as login credentials.
They arrive with social conventions.
We’ve established an etiquette round cellphone numbers. when to maintain a quantity non-public and when to share it. For instance, in the event you name somebody at work they usually’re not in, it’s not cheap to anticipate the office to offer out that particular person’s non-public quantity. We’ve skilled each other find out how to use cellphone numbers correctly. And in the event you abuse a cellphone quantity, anticipate to be blocked.
Whereas we have now nation and space codes, these imply much less and fewer these days. The truth is, they typically solely point out the place you have been residing again once you first received a cellphone. We are able to transfer our quantity from enterprise to enterprise, from one aspect of the nation to the opposite, and from one service to the subsequent. Positive, there may be plenty of nice print on what you’ll be able to and may’t transfer, however all in all, the numbers we use essentially the most are transportable.
However do you really personal your quantity? Mobile community carriers wish to argue that you simply don’t. Extra on that under.
They present up in private handle books.
You in all probability have a private handle guide in your cellphone, which is the way you map a cellphone quantity you need to the identify you name the one that makes use of it. For instance, after I name somebody, the cellphone quantity is matched to nevertheless they know me — Cullen, Cullen Jennings, Dad, you get the thought. There are a number of Cullen Jennings on the earth, however let’s say I’m the one Cullen Jennings in your handle guide. After I name you, my cellphone quantity is then mapped to a human readable identify that you simply selected for me in your cellphone. A unique Cullen Jennings can’t impersonate me after they name you (until they occur to steal my cellphone quantity).
How we are able to make cellphone numbers even higher
Make it simpler to vary numbers.
We’d like a greater collective response to this than what we have now at this time. My daughter received a brand new cellphone quantity just lately, and the one that used to have that quantity had their banking data connected to it. My daughter couldn’t connect her new quantity to her financial institution till the opposite particular person unattached theirs. It was a months-long problem, and the entire time the earlier person’s banking information was accessible to the fallacious particular person.
Say you utilize your quantity to login to WhatsApp or Twitter, then you definitely change numbers. There needs to be a easy solution to disconnect that cellphone quantity from that app together with any others.
There’s a solution to establish if a cellphone quantity within the U.S. has moved from one person to the subsequent, and that’s with the FCC’s Reassigned Numbers Database (RND). This helps companies chorus from contacting somebody who hasn’t given permission to be contacted as a result of they’re utilizing another person’s previous quantity.
With greater than 300 million customers within the database, the RND is a good begin. Whereas it doesn’t have each cellphone quantity on the earth (and is just restricted to the States) and appears to be geared in the direction of companies not end-users, it’s setting a mannequin for fixing this downside.
Make them safer.
How do I do know it’s actually you on the opposite finish of that textual content? We’d like an optimum technique for identification verification with cellphone numbers. Sure, we regularly use SMS to show you possess your personal cellphone, however this technique is much from ironclad. We are able to and may give you higher safety that may face up to SIM-jacking and different assaults. (Telephone numbers are nonetheless one of many safer channels, which is why we preserve utilizing them. It might simply be higher.)
At the moment, our greatest resolution for authenticating cellphone numbers with cellphone calls is STIR/SHAKEN, which is designed to guard in opposition to caller-ID spoofing. STIR/SHAKEN is a collection of protocols and procedures based mostly on the RFC 8224 commonplace by a gaggle of us with the Web Engineering Process Power.
I began engaged on this venture a few years in the past, attempting to enhance the belief we have now in cellphone numbers. If we all know who’s utilizing a cellphone quantity, that builds up the repute system we have now round cellphone numbers. We are able to then use that repute system to cease unhealthy actors from utilizing phone numbers for scams. At the moment, STIR/SHAKEN a required protocol by a number of regulators together with the Federal Communications Fee and the Canadian Radio-television and Telecommunications Fee.
Make folks the true homeowners.
Do you really personal your cellphone quantity? The cell service suppliers of the world would say you didn’t — that they personal your digits as a substitute. However from a regulatory viewpoint, I believe the federal government ought to transfer to permitting folks and companies to regulate their very own numbers completely. To some extent, that is allowed in lots of international locations at this time for some sorts of numbers, however it could be significantly better to be very express that numbers are for the good thing about, and below the management of, the tip customers.
Regardless of these challenges, cellphone numbers aren’t going anyplace. I consider these acquainted, distinctive, worldwide identifiers can be round for years to return.
