I used to know a number to dial that would confirm what the phone number is at the land line phone that I am calling from.

Does anyone know if this is still available in the U.S.

Thanks!

Just call your cell ;)

Another way is to directly call the customer service number of a cell phone provider. They usually say the phone number and ask is this the number your calling about.

Ben. I tried that.:
KISS: I have no clue what the provider is.

To make a long story short, I'd like to plug a land line phone into a jack and then call a phone number that confirms what the phone number is at the location where I plugged the phone into.

Years ago I did this many times but since then I've lost the number that I knew that I could call to get the info.

So to clarify: does anyone know the number that one can call (in the US) that will confirm the phone number that belongs to the line that is being used to call from?

I sent a # to use via PM.

Thanks, it worked. It did not work correctly for Vonage, but when I googled further I found 2 different numbers to use to verify a phone number: https://forums.vonage.com/showthread.php?p=12856

The one that works on Vonage phones, Cell phones and l

The one that works on all phones is 958#

When do you type in 958#?

Dial it like a regular number.

It may not work in your area. It doesn't work in mine. It would be dialed like a regular telephone number. Numbers like *PAY where the letters match the letters on a telco keypad are often used.

What I typed before disappeared.
