Just issued. Call the number first.

United States Cellular - IL issued these blocks within the last 18 months, so many of the numbers in them may not have been assigned to customers yet. Call any number you're interested in, and if it doesn't go to a customer you can contact United States Cellular - IL and you might be able to get it from them.

This is a wireless number. Wireless numbers port between carriers all the time, so the originating carrier often isn't the current one. An HLR (Home Location Register) lookup tells you which carrier currently controls the line. We're planning to offer this as a paid service soon. For now, any HLR-lookup vendor can do it.
