Scam Calls from Area Code 603

Dropped calls and silent hangups define 603's complaint profile more sharply than anything else. Of the 1,265 total complaints logged against this New Hampshire area code between February and June 2026, 248 fall into the dropped-call-or-no-message category, nearly two and a half times the volume of the next largest bucket. That pattern points to autodialers working through number lists faster than live agents can handle connections, a classic high-churn operation rather than a tightly scripted con.

Medical and prescription scams form the clear secondary threat, with 97 complaints. The number 603-310-6017 accounts for 14 of those directly and is the only top-number in the dataset with a confirmed category tie to that bucket. The remaining seven highest-complaint numbers carry no confirmed category, yet several are generating double-digit complaint counts: 603-780-4852 leads all individual numbers at 32 complaints, followed by 603-633-5042 at 19 and 603-570-4474 at 18. The concentration of uncategorized high-volume numbers suggests either rapid spoofing across freshly registered lines or deliberate category evasion.

Impersonation calls, covering government, business, and personal contacts, add 66 complaints, and debt-reduction pitches contribute another 37, with charity solicitation fraud rounding out the confirmed categories at 16. Reported victims span New Hampshire towns including Antrim, Hudson, Dover, Windham, and West Chesterfield, though complaints also arrived from South Carolina and Florida, indicating callers are not limiting their targets to in-state recipients despite the local area code.

The 603 code ranks 163rd out of 358 area codes overall but sits at 19th out of 43 among its peer group, a mid-tier-to-elevated position that suggests steady, organized dialing rather than a brief spike. With 457 distinct numbers generating those 1,265 complaints over roughly five months and activity marked as ongoing, the operation shows no signs of contraction. The dominance of live calls in FCC records, 249 live versus 126 prerecorded, reinforces the read that human-staffed boiler-room capacity is behind a meaningful share of this traffic, particularly within the medical and impersonation segments.
