Re: Phone# w/my FIOS said "No such number" for school

Just an FYI., this website is specifically used for caller ID. This wouldn't indicate if your phone number is provisioned properly.

There is no such thing a 100% certainty, but if the site does an SS7 dip and finds the DN then there's a 99.9% chance that the line is provisioned.

I see many instances where a block of numbers are exchanged between providers and mistakenly give a few subscribers numbers with it. i.e. John has at&t and his number fall in this line range - 555-220-xxxx. Then the company exchanges that entire line range to sprint. Now John can't receive any calls and is putting in a trouble ticket.

When someone does a query into the NPAC database, we see the number now belongs to sprint. This typically doesn't happen on a large scale, but it happens.
