If you select to receive a phone call (mobile phone or landline phone) you will enter a specific digit, as directed, before the verification code is provided. If you have selected phone call verification and you do not answer the phone call, please note that a second call will not be made automatically and the system will NOT leave codes on a voicemail. If you do not answer, you will need to select the option to have the code re-sent. (Note: The "from" phone number may be listed as incoming from anywhere in the United States.)
