About Area Code 309

Area code 309 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 309 a valid area code?

Yes. 309 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 309?

Area code 309 covers 171 cities and communities in Illinois, including Abingdon, Adair, Albany, Aledo, Alexis, and 166 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 309?

All numbers in the 309 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 309 number from a different time zone, check the current local time above to avoid calling outside of business hours.

How do I dial a 309 number?

From within Illinois, dial the 7-digit local number directly if calling within the same rate center, or dial 1 + 309 + 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 1 309 XXX XXXX. The country code for both the United States and Canada in NANP is +1.

Formatting 309 phone numbers

Format 309 numbers using E.164 notation as required by RFC 3966: prefix with +1 and omit dashes and parentheses (e.g., +13095550100). This format ensures tel: links work correctly on all mobile browsers and VoIP apps. See the tel: URI formatting guide for complete examples.
