Do you need your landline phone number on your Resume? Not usually, unless you live in an area where mobile coverage is poor or non-existent which can occur surprisingly close to major cities. Including your mobile number on your Resume is critical, as is an appropriate email address. Where you have poor mobile coverage, it may be worth including both phone numbers on your Resume. Whether it is your landline or mobile number, make sure you have a professional voicemail message on both.
