Prefix Blocks (NPA-NXX)

781 active prefixes in this area code, assigned as 6,600 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.

Ten-Digit Dialing Required

559 now shares its territory with 357. Because of this overlay, local calls in this region must be dialed with all ten digits.

About Area Code 559

Area code 559 is a North American Numbering Plan (NANP) telephone area code assigned to California, United States. It is one of 41 area codes serving California. 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 559 a valid area code?

Yes. 559 is an active North American Numbering Plan (NANP) area code, currently assigned to California, United States. It is safe to answer or dial calls using this area code.

Where is area code 559?

Area code 559 covers 60 cities and communities in California, including Alpaugh, Auberry, Avenal, Badger, Big Creek, and 55 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 559?

All numbers in the 559 area code observe Pacific Time (IANA timezone: America/Los_Angeles). Pacific Time is UTC−8 in winter (PST) and UTC−7 in summer (PDT). When placing a call to a 559 number from a different time zone, check the current local time above to avoid calling outside of business hours.

How do I dial a 559 number?

From within California, dial the 7-digit local number directly if calling within the same rate center, or dial 1 + 559 + 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 1 559 XXX XXXX. The country code for both the United States and Canada in NANP is +1.

Formatting 559 phone numbers

Format 559 numbers using E.164 notation as required by RFC 3966: prefix with +1 and omit dashes and parentheses (e.g., +15595550100). This format ensures tel: links work correctly on all mobile browsers and VoIP apps. See the tel: URI formatting guide for complete examples.
