If a call shows area code 601, the number was issued in the Jackson area — a code active since 1947, on Central time. The same territory is also served by its overlay code (601/769 complex). Keep in mind the code identifies where the number was registered; the person calling may be elsewhere.
The code currently holds 772 working prefixes, held by 35 different carriers. Of these, 455 are pooled prefixes shared by multiple carriers. Numbers are anchored to 106 rate centers — billing localities that fix where each prefix belongs.
The current NANPA exhaust forecast for the 601/769 complex is 3Q 2052.
As demand grew it in turn gave rise to 228 (1997), 662 (1999), 769 (2005).

Worth noting: 601 is the oldest area code in Mississippi, in service since 1947.
Practical takeaway: the 601 label narrows geography to Mississippi, the prefix narrows it to a locality, and neither authenticates a caller. Verification means calling back through a number you found yourself.

FAQ
Where is a 601 number from?
601 is assigned to Jackson and surrounding areas of Mississippi in the Central time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
Is 601 a toll-free number?
No. 601 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 769 and 601 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 601/769 complex shares one service area, and local calls are dialed with 10 digits.
