Numbering and Overlay Considerations
The 042 NDC is a geographic code that covers County Louth and parts of County Monaghan. The 4292 prefix is a specific exchange block within this NDC.

However, number portability allows subscribers to retain their numbers when switching providers, so a number with the 4292 prefix may be served by any operator.
