Callers from the 603 area code frequently try the "Howard, Clark & Associates" legal threat scam. They claim you are being sued or have unpaid debts to trick you into making an immediate payment.
"My husband received two calls from Kevin Hall with Howard Clark and Associates saying that a civil claim was going to be filed against him... No law firm will call you before filing a suit and process servers don't call to check if you're home before serving you with papers."
"Got a call from auto warranty services. Asked for the name of the company and they hang up. Block them and they still get through on the same number, 11 times today."
"Terrible robo voice trying to intimidate me that they are from the IRS and that federal agents will take me into custody if I do not return their call. Bite me you shitbag robot."
"Got a robo call claiming to be Amazon wanted to confirm my purchase of a I-phone in the amount of $900. I did not respond to it request to press 1 to speak to a representative. I let it sit until it hung up."
"These people claim to be the NH State Troopers but are not. I called the NH state police and they confirmed it's a scam, but declined to do anything about it, and instead told me to call the municipal police in my city."
"She said her name was Erin and that she was a vacation specialist and asked if i could hear her ok. I answered 'yes' and she hung up."
Phone numbers with the 603 area code prefix originate from across the entire state of New Hampshire, as it is the sole area code for the state.
Although an overlay area code was once anticipated for New Hampshire, with a plan to activate a second area code by 2013, the need has been deferred until at least 2032 due to changes in allocation policies and number reclamation. However, ten-digit dialing became mandatory for area code 603 on October 24, 2021. This transition was required because the 988 central office code was designated nationwide as a dialing code for the National Suicide Prevention Lifeline, creating a conflict for exchanges that previously allowed seven-digit dialing.
No, 603 is New Hampshire's only area code, covering the entire state including Manchester, Nashua, and Concord. Scammers spoof it to appear as a neighbor calling, which significantly raises the odds that a New Hampshire resident will answer.
Neighbor spoofing, where the prefix matches the recipient's own, is the main draw of faking a 603 number. Fake law firms like "Howard, Clark and Associates" threatening civil complaints with phony case numbers are heavily reported here, alongside callers impersonating the NH State Troopers Association soliciting credit card donations that the actual state police have publicly confirmed are fraudulent.
