Phone Prefixes in Cache Valley Utah

These are the phone numbers that are considered "local" in the Cache Valley Utah. For example a phone number like 435-753-1234 is from Qwest...but if it is a cell number it can be taken to another provider under WNP - WIreless Number Portability. So this is not an absolutely clean identifier. Also, the legal owner of the rights to the prefixes may be aligned with another organization. For example 881 is Cingular, but legally known as Blue Licenses Holdings.

(1) Prefixes used to be allocated to phone companies in groups of 10,000 ie 232-0000 to 232-9999. That wasted lots in smaller towns and cell/other services. So now they are allocated in groups of 1000, e.g 232-0000 to 232-0999

(2) Isn't it interesting how many "switches" are NOT in Cache Valley. Mostly for the cell and competitive companies

 

Cell and other services, but still quite a few!

 

Here is a good resource for phone stuff!
