However, the Wasatch Front is not only home to most of Utah's landlines, but also the great majority of its pagers, cell phones and fax machines. As a result, 801 was close to exhaustion once again within only two years. In 2000, the

, Public Service Commission of Utah, July 12, 2007. Accessed July 13, 2007. In July 2007, the PSC announced that the capacity created by the conservation measures would be exhausted by June 2008, finally necessitating the implementation of area code 385. The same announcement stated that 385 would be implemented as an overlay rather than a split, so that the Wasatch Front would be served by both area codes. Everyone who already had an 801 number could keep it. 385 entered service on June 1, 2008, with a year-long permissive dialing period beginning during which seven and ten-digit calls could be completed. Ten-digit dialing became mandatory along the Wasatch Front on June 1, 2009.385 area code = 10-digit dialing
Utah Public Service Commission Accessed July 9, 2008. As new wireless devices have become prominent over new landline adoption, outside abandoned 801 numbers being placed back into the pool, most new numbers have been assigned the 385 area code.
