Use the E.164 format for clickable phone links (RFC 3966):
<a href="tel:+14425550100">+14425550100</a><a href="tel:+14425550199">+14425550199</a>Area code 442 is a North American Numbering Plan (NANP) telephone area code assigned to California, United States.

Area code 442 covers 78 rate centers across California. Communities served include Baker, Barstow: Barstow Da, Barstow: Yermo Da, Benton, Big Pine, and 73 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 442 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 442 number from a different time zone, check the current local time above to avoid calling outside of business hours.
From within California, dial the 7-digit local number directly if calling within the same rate center, or dial 1 + 442 + 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 1 442 XXX XXXX. The country code for both the United States and Canada in NANP is +1.
Format 442 numbers using E.164 notation as required by RFC 3966: prefix with +1 and omit dashes and parentheses (e.g., +14425550100). This format ensures tel: links work correctly on all mobile browsers and VoIP apps. See the tel: URI formatting guide for complete examples.
