Use the E.164 format for clickable phone links (RFC 3966):
<a href="tel:+16045550100">+16045550100</a><a href="tel:+16045550199">+16045550199</a>Area code 604 is a North American Numbering Plan (NANP) telephone area code assigned to British Columbia, Canada.

Area code 604 covers 43 rate centers across British Columbia. Communities served include Abbotsford, Agassiz, Aldergrove, Black Point, Boston Bar, and 38 more localities. Rate centers are the geographic building blocks telephone carriers use to determine local calling boundaries and to assign numbers when a business or individual requests a phone number in a specific city.
All numbers in the 604 area code observe Pacific Time (IANA timezone: America/Los_Angeles). Pacific Time is UTC−8 in winter (PST) and UTC−7 in summer (PDT). When placing a call to a 604 number from a different time zone, check the current local time above to avoid calling outside of business hours.
From within British Columbia, dial the 7-digit local number directly if calling within the same rate center, or dial 1 + 604 + 7-digit number for long-distance calls within North America. From outside the US or Canada, dial your country's international exit code followed by 1 604 XXX XXXX. The country code for both the United States and Canada in NANP is +1.
Format 604 numbers using E.164 notation as required by RFC 3966: prefix with +1 and omit dashes and parentheses (e.g., +16045550100). This format ensures tel: links work correctly on all mobile browsers and VoIP apps. See the tel: URI formatting guide for complete examples.
