Use the E.164 format for clickable phone links (RFC 3966):
<a href="tel:+13025550100">+13025550100</a><a href="tel:+13025550199">+13025550199</a>Area code 302 is a North American Numbering Plan (NANP) telephone area code assigned to Delaware, United States.

Yes. 302 is an active North American Numbering Plan (NANP) area code, currently assigned to Delaware, United States. It is safe to answer or dial calls using this area code.
Area code 302 covers 30 cities and communities in Delaware, including Angola, Bridgeville, Camden, Dagsboro, Delaware City, and 25 more localities. This is based on telephone company rate center data — the geographic areas 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 302 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 302 number from a different time zone, check the current local time above to avoid calling outside of business hours.
From within Delaware, dial the 7-digit local number directly if calling within the same rate center, or dial 1 + 302 + 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 1 302 XXX XXXX. The country code for both the United States and Canada in NANP is +1.
Format 302 numbers using E.164 notation as required by RFC 3966: prefix with +1 and omit dashes and parentheses (e.g., +13025550100). This format ensures tel: links work correctly on all mobile browsers and VoIP apps. See the tel: URI formatting guide for complete examples.
