Prefix Blocks (NPA-NXX)

599 active prefixes in this area code, assigned as 4,322 thousands-blocks — pooling splits one prefix across several carriers, so each block is listed separately with the rate centre it is homed to, its carrier of record, and the switch that serves it.

About Area Code 337

Area code 337 is a North American Numbering Plan (NANP) telephone area code assigned to Louisiana, United States. It is one of 6 area codes serving Louisiana. 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 337 a valid area code?

Yes. 337 is an active North American Numbering Plan (NANP) area code, currently assigned to Louisiana, United States. It is safe to answer or dial calls using this area code.

Where is area code 337?

Area code 337 covers 75 cities and communities in Louisiana, including Abbeville, Arnaudville, Baldwin, Basile, Breaux Bridge, and 70 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 337?

All numbers in the 337 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 337 number from a different time zone, check the current local time above to avoid calling outside of business hours.

How do I dial a 337 number?

From within Louisiana, dial the 7-digit local number directly if calling within the same rate center, or dial 1 + 337 + 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 1 337 XXX XXXX. The country code for both the United States and Canada in NANP is +1.

Formatting 337 phone numbers

Format 337 numbers using E.164 notation as required by RFC 3966: prefix with +1 and omit dashes and parentheses (e.g., +13375550100). This format ensures tel: links work correctly on all mobile browsers and VoIP apps. See the tel: URI formatting guide for complete examples.
