It designated the province of <a href="/wiki/British_Columbia" title="British Columbia">British Columbia</a>. Until 1988, 604 also included <a href="/wiki/Point_Roberts,_Washington" title="Point Roberts, Washington">Point Roberts, Washington</a>, a <a href="/wiki/Pene-enclave" class="mw-redirect" title="Pene-enclave">pene-enclave</a> of the United States; Point Roberts was transferred in 1988 to <a href="/wiki/Area_code_206" title="Area code 206">area code 206</a> and is now served by <a href="/wiki/Area_code_360" title="Area code 360">area code 360</a>. </p><p>Despite British Columbia's growth in the second half of the 20th century, 604 remained the province's sole area code for nearly 50 years. By the mid-1990s, however, the need for a new area code in the province could no longer be staved off, largely because of Canada's number allocation system. Every <a href="/wiki/Competitive_local_exchange_carrier" title="Competitive local exchange carrier">competitive local exchange carrier</a> in the country is allocated blocks of 10,000 numbers, corresponding to a single three-digit prefix, for every rate centre in which it offers service, even for the smallest hamlets. </p><p>While smaller rate centres usually do not need that many numbers, once a number is assigned to a carrier and rate centre, it cannot be moved elsewhere, even to a larger rate centre. Additionally, some larger cities are split between multiple rate centres that have never been amalgamated. That resulted in thousands of wasted numbers, and the growing popularity of <a href="/wiki/Mobile_phone" title="Mobile phone">cell phones</a>, <a href="/wiki/Pager" title="Pager">pagers</a> and <a href="/wiki/Fax" title="Fax">fax machines</a> has only exacerbated that problem. The number shortage was particularly severe in the Lower Mainland, which was home to most of the province's <a href="/wiki/Landline" title="Landline">landlines</a> and most of its other telecommunications devices requiring phone numbers. </p><p>In 1997, 604 was cut back to the Lower Mainland, with the new <a href="/wiki/Area_code_250" title="Area code 250">area code 250</a> created for the remainder of the province.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>The 1997 split was intended as a long-term solution for the Lower Mainland. However, within three years, 604 was close to exhaustion, once again because of the aforementioned number allocation problem and the continued proliferation of cell phones and pagers. Numbers tended to be used up fairly quickly in Vancouver and its immediate neighbours because of their rapid growth, but the number allocation problem was still severe in the Lower Mainland as a whole. </p><p>On November 3, 2001, <a href="/wiki/Area_code_778" class="mw-redirect" title="Area code 778">area code 778</a> was implemented as a <a href="/wiki/Overlay_plan" class="mw-redirect" title="Overlay plan">concentrated overlay</a> for the two largest <a href="/wiki/List_of_regional_districts_of_British_Columbia" title="List of regional districts of British Columbia">regional districts</a> in the Lower Mainland, <a href="/wiki/Metro_Vancouver" class="mw-redirect" title="Metro Vancouver">Metro Vancouver</a> and the <a href="/wiki/Fraser_Valley_Regional_District" title="Fraser Valley Regional District">Fraser Valley Regional District</a>. The experiment was announced in <a href="/wiki/NANP" class="mw-redirect" title="NANP">NANP</a> planning letter PL-246.
