839 area code — Columbia, SC geographic

Data: NANPA public reports, current as of July 28, 2026.

Area code 839 is a geographic code serving Columbia, South Carolina in the Eastern time zone. It has been in service since May 26, 2020. The same territory is also served by its overlay code (803/839 complex). Keep in mind the code identifies where the number was registered; the person calling may be elsewhere.

The code currently holds 170 working prefixes, held by 24 different carriers. Of these, 170 are pooled prefixes shared by multiple carriers. Numbers are anchored to 51 rate centers — billing localities that fix where each prefix belongs.

The code was carved out of 803 (2020).

The current NANPA exhaust forecast for the 803/839 complex is 1Q 2046.

Local calls inside 839 are dialed 10D; 1+10 digit permissible at each service providers discretion.

If a 839 call asks for money or personal data, treat the displayed number as unverified: hang up and reach the organization through its published number. Numbering data locates numbers, not callers.

FAQ

Is 839 a toll-free number?

No. 839 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.

Why do 803 and 839 cover the same place?

They are overlays: when a code runs low on numbers, a new code is added over the same territory instead of splitting it. The 803/839 complex shares one service area, and local calls are dialed with 10 digits.

Will 839 run out of numbers?
