==Ten-digit dialing==
Prior to October 2021, area code 940 had telephone numbers assigned for the [central office code](/source/central_office_code) 988. In 2020, ''988'' was designated nationwide as a dialing code for the [National Suicide Prevention Lifeline](/source/National_Suicide_Prevention_Lifeline), which created a conflict for exchanges that permit [seven-digit dialing](/source/seven-digit_dialing). This area code was therefore scheduled to transition to [ten-digit dialing](/source/ten-digit_dialing) by October 24, 2021.<ref name="pl556">{{cite web|url=https://nationalnanpa.com/pdf/PL_556.pdf|date=January 8, 2021|publisher=North American Numbering Plan Administrator |title=Transition to 10-digit dialing (for 988 as 3-digit access to National Suicide Prevention Hotline)|access-date=March 9, 2021}}</ref>
