Mandatory 10-Digit Dialing Impacts

Recently there has been media coverage explaining how Iowans in the 515/319 area codes will be required to dial 10 digits starting April 24, 2021.

The FCC ordered that any area code that has the 988 prefix and has 7-digit local dialing be transitioned to 10-digit local dialing to ensure everyone is able to reach the National Suicide Prevention Lifeline using the 3-digit 988 code. Customers must continue to dial 1-800-273-TALK (8255) to reach the Lifeline until July 16, 2022.


What do ICN Customers need to do?

The majority of our customers will not be affected by this change.

Managed Voice Customers
If ICN is providing local handset voice services through our Managed Voice Platform, there is no change in dialing required. Our Voice system already requires 10-digit (area code+ telephone number) dialing to complete a call.

1FB Customers (Business Line)
For locations that ICN provides 1FB services (i.e. fire alarms or elevators) in the 515/319 area codes, please note that 10-digit dialing will be required starting April 24, 2021, and mandatory by October 24, 2021. If you have alarming or emergency ring-down circuits that forward calls to a 7-digit number, those forwarding numbers will need to be changed to 10-digits in the alarming/pbx system. Those programmed settings will need to be changed by each customer or your contracted vendor.


Mandatory 10-Digit Dialing FAQs

Does this apply to Iowa?
Yes. Implementation of this Order requires all covered providers to make 10-digit dialing mandatory for all local calls in the Iowa 319 and 515 area codes.

Why is the local dialing plan changing?
On July 16, 2020, the FCC adopted an Order (FCC 20-100) approving 988 as the 3-digit abbreviated dialing code to reach the National Suicide Prevention Lifeline, starting July 16, 2022. Customers must continue to dial 1-800-273-TALK (8255) to reach the Lifeline until July 16, 2022.

Why is 10-digit dialing going to be required in this area code?
The FCC ordered that any area code that has the 988 prefix and has 7-digit local dialing be transitioned to 10-digit local dialing to ensure everyone is able to reach the National Suicide Prevention Lifeline using the 3-digit 988 code. For 988 to work in the Iowa 319 and 515 area codes, 10-digit local dialing must first be implemented.

Will everyone in the 319 and 515 area codes have to dial 10 digits for local calls?
Yes. Every customer with a number from the 319 and 515 area codes will change to mandatory 10-digit dialing for local calls. Dialing 7 digits for local calls will be prohibited for all customers in the entire area code.

What will be the new dialing procedure?
To complete local calls, the new dialing procedure requires callers to dial the area code + telephone number. This means that all local calls in the entire 319 and 515 area codes that are currently dialed with 7 digits will need to be dialed using the area code + telephone number.

When will the dialing change begin?
Beginning April 24, 2021, you should start dialing 10 digits (area code + telephone number) for all local calls.

  • Currently, ICN’s MVS (including analog lines) requires 10-digit dialing.

When will the dialing change become mandatory?
Beginning October 24, 2021, you must dial 10 digits (area code + telephone number) for all local calls. On and after this date, local calls dialed with only 7 digits may not be completed, and a recording will inform you that your call cannot be completed as dialed. If you get this recording, you must hang up and dial again using the area code with the 7-digit telephone number.

What other changes need to be made?

See ICN’s 1FB customer notification above.

For a Special Consideration: 

Please make note that you may need to verify dial plans on your local pbx or phone systems to make sure that dialed 10 digits do not send out on your ICN provided long distance service trunks. Please make sure that you review this with your local phone system technician or vendor to make sure that you will not incur any additional costs by sending local calls down your long-distance trunk lines with the ICN.

In addition to changing your dialing patterns, all services, automatic dialing equipment, or other types of equipment that are programmed to complete local calls using only 7-digit numbers will need to be reprogrammed to complete calls to 10-digit numbers.

Some examples are:

  • life safety systems or medical monitoring devices
  • PBXs
  • fax machines
  • Internet dial-up numbers
  • fire or burglar alarm and security systems or gates
  • speed dialers
  • mobile or other wireless phone contact lists
  • call forwarding settings
  • voicemail services, and other similar functions

What will remain the same?

  • Your telephone number, including current area code, will not change.
  • The price of a call, coverage area, or other rates and services will not change due to the dialing change.
  • What is a local call now will remain a local call regardless of the number of digits dialed.
  • You will continue to dial 1+ area code + telephone number for all long distance calls.
  • You can still dial just three digits to reach 711 (relay services) and 911 (emergency services).
  • Any 211, 311, 411, 511, 611, or 811 services available in your community can still be reached by dialing their three-digit codes.
  • The National Suicide Prevention Lifeline can still be reached by dialing 1-800-273-TALK (8255).
