Area code 641 covers 223 rate centers across Iowa. Communities served include Ackley, Adair, Afton, Agency, Albia, and 218 more localities.

All numbers in the 641 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 641 number from a different time zone, check the current local time above to avoid calling outside of business hours.
From within Iowa, dial the 7-digit local number directly if calling within the same rate center, or dial 1 + 641 + 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 1 641 XXX XXXX. The country code for both the United States and Canada in NANP is +1.
Format 641 numbers using E.164 notation as required by RFC 3966: prefix with +1 and omit dashes and parentheses (e.g., +16415550100). This format ensures tel: links work correctly on all mobile browsers and VoIP apps. See the tel: URI formatting guide for complete examples.
