The New 667 Area Code: Frequently Asked Questions
The new 667 area code will serve customers in the same geographic region as the current 410 and 443 area codes when implemented, but only customers initiating new lines or services after March 24, 2012. No lines with 410 or 443 numbers will be changed to 667 numbers.
2. When will the 410 / 443 / 667 area code overlay go into effect?
As early as March 24, 2012, new lines or services may be assigned a phone number with the 667 area code. As is current practice with calls to 410 and 443 numbers, calls to the new 667 area code will require callers to dial the area code and 7-digit phone number.
3. What is an area code overlay?
An overlay is the addition of another area code to
the same geographic region as an existing area code. In this instance, the new
667 area code is being added to the same region served by the 410 and 443 area
The 667 overlay does not require any customers to change their existing area code or telephone numbers, but it does require anyone receiving a 667 telephone number to dial the area code and the 7-digit number for all calls, including calls within the same area code.
For 410 and 443 customers, there will be no change to
your existing area code, phone number or dialing requirement. The 410 and 443
area codes already have mandatory 10-digit dialing in place and no changes will
be made to those dialing requirements with the implementation of the new 667
area code. The 410 and 443 customers simply need to be aware that the new 667
area code will serve the same geographic region as the existing 410 and 443
If you are a customer who receives a 667 telephone number, you should be aware that 10-digit dialing will be required for all calls, even those within the same area code.
No; 410 and 443 customers will only need to continue to dial the area code for all calls. Your current area code and 7-digit telephone number will not change. The price of a call, your wireless plan and coverage area, and other rates and services will not change because of the 667 overlay. All local calls will remain local, regardless of the number of digits dialed.
The following items will not change due to the overlay:
o Your area code and 7-digit phone number
o The price of a call, your coverage area, and your other rates and services
o Any 3-digit number that may be available in your community can still be dialed with just three digits (e.g., 211, 311, 411, 511, 611, 711, 811, 911)
Beginning March 24, 2012, new phone lines or services may be assigned numbers with the 667 area code. If you are assigned a phone number with the 667 area code, you will need to dial the area code for all calls, including calls to another 667 number.
Since three area codes will serve the same area, if you have a 410, 443, or 667 area code, you will need to dial the area code for ALL calls, including calls within your same area code.
If you have any questions about the 410, 443, and 667 area code overlay, please contact your local carrier. Updates will be posted to the PSC website.
