Ten Digit Phone Dialing
On April 24, 10-digit dialing for local 405 phone calls (405 + local number) becomes mandatory, ending the period when local calls could be completed either with only 7 digits. Businesses and residents who have not yet prepared for 10-digit dialing of local calls within the 405 area code should do so now according to the Oklahoma Corporation Commission. The move to 10-digit dialing for local 405 area code calls is necessary to enable the addition of another area code for the area currently served by only 405. The new, additional area code (572) is needed to ensure there will be enough telephone numbers available for the area. Existing phone numbers will not change, and what is currently a local call will remain a local call. Residents and businesses should check all devices that may use telephone numbers including such things as security systems, office telecommunication systems, certain inventory systems, etc. and make sure the systems are set up for 10-digit dialing for local 405 area code calls.
