About Area Code 618

Area code 618 is a North American Numbering Plan (NANP) telephone area code assigned to Illinois, United States. It is one of 17 area codes serving Illinois. As population and demand for phone numbers grew, the region was divided into multiple numbering plan areas to avoid exhausting the available 7-digit number pool.

Is 618 a valid area code?

Yes. 618 is an active North American Numbering Plan (NANP) area code, currently assigned to Illinois, United States. It is safe to answer or dial calls using this area code.

Where is area code 618?

Area code 618 covers 243 cities and communities in Illinois, including Addieville, Albers, Albion, Alhambra, Allendale, and 238 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.

What time zone is area code 618?

All numbers in the 618 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 618 number from a different time zone, check the current local time above to avoid calling outside of business hours.

How do I dial a 618 number?

From within Illinois, dial the 7-digit local number directly if calling within the same rate center, or dial 1 + 618 + 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 1 618 XXX XXXX. The country code for both the United States and Canada in NANP is +1.

Formatting 618 phone numbers

Format 618 numbers using E.164 notation as required by RFC 3966: prefix with +1 and omit dashes and parentheses (e.g., +16185550100). This format ensures tel: links work correctly on all mobile browsers and VoIP apps. See the tel: URI formatting guide for complete examples.
