10 Number Dialing Required on Saturday!
Starting Saturday, April 24th, 2021, you will need to begin using the full 10-digit dialing for all telephone calls. In addition to the 405 area code, 572 will be added for the Oklahoma City Metro area. The 572 area code will be assigned to new numbers starting May 24th.
This new area code will not require Oklahomans with an existing phone number to change numbers or area codes. Be sure to check the programmed speed dial numbers on your phones and in contact address lists prior to this date.
After Saturday, if you call using just the 7 digits for local calls, your calls will no longer go through unless itís proceeded with the correct area code. Examples of other dialings that will be affected include fax machines, life safety systems, alarm and security systems, speed dialers, call forwarding settings and voicemail services.
Be advised that this will not affect the dialing of 911 as you may continue to still dial the 3 digits for emergency service.
Start practicing this ten number dialing in your daily calls in preparation for this change. Be sure to update all business cards, signature lines, and letterhead with your area code.
