Area code 401 covers 25 rate centers across Rhode Island. Rate centers are geographic areas used by telephone companies to determine local calling boundaries.
Use the E.164 format for clickable phone links (RFC 3966):
<a href="tel:+14015550100">+14015550100</a><a href="tel:+14015550199">+14015550199</a>Area code 401 is a North American Numbering Plan (NANP) telephone area code assigned to Rhode Island, United States.

Area code 401 covers 25 rate centers across Rhode Island. Communities served include Block Island, Bristol, Carolina, Centredale, Coventry, and 20 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 401 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 401 number from a different time zone, check the current local time above to avoid calling outside of business hours.
From within Rhode Island, dial the 7-digit local number directly if calling within the same rate center, or dial 1 + 401 + 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 1 401 XXX XXXX. The country code for both the United States and Canada in NANP is +1.
Format 401 numbers using E.164 notation as required by RFC 3966: prefix with +1 and omit dashes and parentheses (e.g., +14015550100). This format ensures tel: links work correctly on all mobile browsers and VoIP apps. See the tel: URI formatting guide for complete examples.
