The 803 area code covers Columbia, South Carolina, Eastern time zone, and dates back to January 1, 1947. It is part of the 803/839 overlay complex — these codes share the same territory. Note that porting and VoIP mean a 803 number can be used from anywhere — the code marks where the number was assigned.
783 central-office prefixes are currently active in this code, spread across 52 code-holding carriers. Thousands-block pooling applies to 534 prefixes, so a single prefix can belong to several carriers. Its prefixes map to 82 distinct rate centers.
NANPA projects numbering capacity for the 803/839 complex to exhaust in 1Q 2046.
Dialing: 10D locally, 10D to other codes (1+10 digit permissible at each service provider discretion).
Worth noting: 803 is the oldest area code in South Carolina, in service since 1947.
Practical takeaway: the 803 label narrows geography to South Carolina, the prefix narrows it to a locality, and neither authenticates a caller. Verification means calling back through a number you found yourself.
It has since spawned 864 (1995), 843 (1998), 839 (2020).

FAQ
Why do 839 and 803 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 803 run out of numbers?
NANPA's current forecast projects exhaust in 1Q 2046 — decades of capacity remain.
Why am I getting spam calls from 803 numbers?
Scammers spoof recognizable area codes so calls look local or familiar. A displayed 803 number does not prove the call originated there — see our guide to spotting spoofed calls.
Where is a 803 number from?
803 is assigned to Columbia and surrounding areas of South Carolina in the Eastern time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
