Utah 801/385 Area Code Overlay

New 385 Area Code Effective March 1, 2009

En Español

Our goal at Qwest is to offer services that meet your communications needs and to provide timely information regarding changes or events that influence your service.

In order to accommodate the growing need for telephone numbers in Utah, the Utah Public Service Commission has ordered the new 385 area code to be added to the telephone exchanges currently serviced by the 801 area code today. This change will affect the way you dial your calls by requiring you to dial 10-digits for all local calls.

An area code Overlay is the addition of another area code (385) to the same geographic region as an existing area code (801). An Overlay does not require customers to change their existing area code or their 7-digit telephone number.

Effective June 1, 2008, you should begin using the new 10-digit dialing procedure whenever you place a local call from the 801 area code. If you forget and use the old procedure of dialing just 7-digits, your call will still be completed during the grace period. Long-distance calls require 1+10-digit dialing.

Beginning March 1, 2009, the grace period will end and you must use the new 10-digit dialing procedure for all local calls. On this date, if you do not dial all 10-digits, your call will not be completed, and a recording will instruct you to hang up and dial again. Additionally, new telephone lines or services may be assigned numbers with the 385 area code at this time.

Please refer to the Frequently Asked Questions below or call Qwest at one of the numbers below with any questions regarding the addition of the 385 area code or the new 10-digital dialing requirements.

    Back to FAQs

  2. What is an area code overlay?

    An area code overlay is a form of area code change that adds area code(s) to the same geographic region. In this case, the 385 area code will be added to the same geographic region of the 801 area code. Now, the entire 801 geographic region will have the 385 area code and the 801 area code. In many parts of the country, multiple area codes co-exist within the same geographic region. People with telephone numbers with the 801 area code will retain their current telephone number(s) and area code. People who would like to have new or additional telephone numbers or telecommunications services may be given telephone numbers with the new 385 area code.

  3. Why was the area code overlay chosen instead of the area code split?

    Traditionally, area codes have been split to provide more prefixes for the telecommunications industry and its customers, creating smaller geographic areas. As geographic areas become smaller, it becomes more difficult to subdivide an area code any further without separating close knit communities of interest or cities.

  4. Will I have to change my 7-digit telephone number or area code?

    No. Area code overlays allow people to retain their current telephone number(s) and area code.

  6. Will this area code overlay alter how I dial my calls?

    • Yes. You will need to dial 10-digits (area code + 7-digit phone number) for all local calls. Even if you are calling your next door neighbor, you must dial the area code + 7-digit phone number (example 801 + XXX-XXXX).
    • The Federal Communications Commission (FCC) requires dialing the area code + telephone number for all calls where an area code overlay exists. The FCC believes this maximizes numbering resource optimization, minimizes anti-competitive effects due to dialing disparities, and avoids customer confusion.
