How scammers get your phone number, and how to make it harder
Your number leaks from more places than you think. Here is where it actually comes from and what you can realistically do about it.
A work number you can switch off at six, hand over when you leave, and keep off every public listing. Here's how to get one and what to check before you do.

If your work number is also your personal number, you already know the problem. Customers call at nine in the evening. You cannot hand the line to anyone when you take a week off. And the number your clients have is the same one your mother has.
A separate work number fixes all three. Here is how to get one, and what to check before you pay for anything.
Most people should start here. A second-number app gives you another real, dialable number that rings on the phone already in your pocket. No second handset, no second carrier bill. Calls and texts to the work number arrive in the app; everything else carries on as normal.
It is the cheapest option by a distance, usually a few dollars a week, and the fastest — you can be working in a few minutes.
Most carriers will sell you an additional line, and newer phones can run it as an eSIM alongside your existing one. It costs considerably more than an app, but the number behaves like a normal mobile number in every respect, which matters if you need reliable SMS from banks and verification services.
Extensions, hunt groups, hold music, a receptionist menu. Once you have staff who need to transfer calls to each other, this is the right answer. Before that it is expensive overhead for a problem you do not have.
Hours you can enforce. This is the real prize. A separate line can be silenced at six without silencing your family. Trying to do the same with one number means either taking the call or ignoring a ringing phone, and most people take the call.
A number you can hand over. When you hire someone, go on holiday, or sell the business, the work number goes with the job. Your personal number cannot, which is how people end up fielding calls for a business they left two years ago.
Separation you can see. Work calls arrive flagged as work. You know what you are picking up before you answer it — useful on a Saturday.
A local presence. Most services let you choose the area code. If your customers are in one city and you are in another, a local number gets answered more often than one that looks out of town.
One number to burn. If the work number ends up scraped and sold, you can replace it without telling your bank, your doctor and everyone you know.
Getting the number is five minutes. Making it useful takes a little thought.
If you are running anything where strangers need to reach you — a trade, a practice, a side business, freelance work — yes, and it is one of the cheapest problems you will ever solve.
If your work number is only known to colleagues who respect your evenings, you can skip it. The value is in the boundary, and you only need the boundary if something is currently crossing it.
