0301 numbers

Ofcom records show that numbers starting 0301 are protected from allocation. Where numbering capacity has been withdrawn from service, the block or code is sterilised for a period, typically 2 years. Alternatively the Ofcom Numbering Unit might protect capacity for a limited period, to avoid dialling errors into similar codes

The correct way to write telephone numbers beginning 0301 is in the format 0301 xxx xxxx
