Use the E.164 format for clickable phone links (RFC 3966):
<a href="tel:+17705550100">+17705550100</a><a href="tel:+17705550199">+17705550199</a>Area code 770 is a North American Numbering Plan (NANP) telephone area code assigned to Georgia, United States.

Area code 770 covers 42 rate centers across Georgia. Communities served include Adairsville, Atlanta, Atlanta Northeast, Atlanta Northwest, Atlanta South, and 37 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 770 area code observe Eastern Time (IANA timezone: America/New_York). Eastern Time is UTC−5 in winter (EST) and UTC−4 in summer (EDT). When placing a call to a 770 number from a different time zone, check the current local time above to avoid calling outside of business hours.
From within Georgia, dial the 7-digit local number directly if calling within the same rate center, or dial 1 + 770 + 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 1 770 XXX XXXX. The country code for both the United States and Canada in NANP is +1.
Format 770 numbers using E.164 notation as required by RFC 3966: prefix with +1 and omit dashes and parentheses (e.g., +17705550100). This format ensures tel: links work correctly on all mobile browsers and VoIP apps. See the tel: URI formatting guide for complete examples.
