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.
Scammers pose as law firms threatening civil complaints to harvest Social Security numbers and addresses.
"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."
Automated messages claiming extended auto warranties are expiring to push expensive service contracts.
"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."
Robocalls threaten arrest or SSN suspension to extort immediate payment over fake federal investigations.
"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."
Automated calls allege compromised iCloud accounts or fraudulent $900 iPhone orders to steal remote computer access.
"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."
Persistent telemarketers impersonate state police associations using guilt tactics to illegally charge credit cards.
"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."
Callers ask "Can you hear me?" to record a "Yes" response used to authorize fraudulent telephone bill charges.
"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.
New Hampshire's single statewide area code, 603 connects callers from Manchester to Nashua to Concord across a state with a surprisingly diverse economic profile. Dartmouth-Hitchcock Health schedulers, Fidelity Investments support lines, and BAE Systems recruiters are among the most frequent callers.
