New "2-way Split" Relief Alternative Approved for 801 Area Code
New 385 Area Code - Split in Provo & Ogden - Effective December 31, 2000

WASHINGTON, D.C. (May 8, 2000) The North American Numbering Plan Administration (NANPA) announced today that a new area code --385-- has been assigned to the 801 calling area which serves Salt Lake City.

The relief plan, adopted by the Utah Public Service Commission (UPSC) on April 26, calls for a two-way, non-contiguous geographic split of the 801 calling area that allows Salt Lake County to retain the 801 area code, while the areas south and north will receive the new 385 area code.

The southern section of the 801 area code serves Utah County and includes such cities and communities as American Fork, Orem, Provo and Spanish Fork, and the northern section of the 801 area code, which serves Morgan, Davis and Weber counties includes Ogden, Morgan, Kaysville and Bountiful.

The central portion of Salt Lake County will retain the 801 area code. Some of the cities and communities retaining the 801 area code include Salt Lake City, Kearns, Alta, Murray, Midvale, and Sandy.

The Geographic Split

The implementation of the 801 relief plan begins with the introduction of the 385 area code during a "permissive" dialing period, which starts December 31, 2000. During this period, customers can use either the 801 or the new 385 area code to place calls to the new area code calling areas. In addition, customers can also place calls between the 801 and 385 calling areas by dialing just seven-digits during the permissive period.

Mandatory dialing of the 385 area code begins in mid-year 2001. (The specific timeframe will be determined at a later date by the industry). After that date, callers who do not use the new area code will receive a recorded message reminding them that the area code has changed. They will be required to redial the number using the correct area code. The recorded reminder will be available for approximately three months. Customers in the new 385 area code will still be able to make calls to other numbers in the 385 area code by dialing just the seven-digit number.

Why New Area Codes are Needed and How to Plan

Joe Cocke, NANPA's senior area code relief planner for the western region, including Utah, said the introduction of a new area code is needed due to an increase in competition in the local phone service market, the growing demand by the public for additional telephone numbers, and a technical requirement in the phone network that allocates phone numbers in blocks of 10,000.

When switching to or adding a new area code, customers should remember the following:

  • Changing stationery, business cards and advertising to reflect the correct area code.
  • Updating fax machine group calling lists.
  • Reprogramming speed dialers, auto dialers, alarms and PBX (private phone systems).
  • Reprogramming outdial lists on personal computers.

Cocke said the introduction of the 385 area code will not affect the price of telephone calls. "Local calls will remain local calls regardless of the area code dialed," he noted.
