All numbers in the 318 area code observe Central Time (IANA timezone: America/Chicago). Central Time is UTC−6 in winter (CST) and UTC−5 in summer (CDT). When placing a call to a 318 number from a different time zone, check the current local time above to avoid calling outside of business hours.
From within Louisiana, dial the 7-digit local number directly if calling within the same rate center, or dial 1 + 318 + 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 1 318 XXX XXXX. The country code for both the United States and Canada in NANP is +1.
Format 318 numbers using E.164 notation as required by RFC 3966: prefix with +1 and omit dashes and parentheses (e.g., +13185550100). This format ensures tel: links work correctly on all mobile browsers and VoIP apps. See the tel: URI formatting guide for complete examples.
