329 overlay codes and dialing
The 329 territory is covered by an overlay of 2 area codes: 329, 845. All of them serve the same geographic area, and the original code is 845. Because more than one code covers the same ground, 10-digit dialing is mandatory — you must dial the area code for every local call. New phone lines may be assigned any of these codes.
History of the 329 area code

Is 329 a scam or spam risk?
329 is a legitimate geographic area code, not a premium or toll line, so a call from it costs you nothing extra. That said, scammers frequently spoof real local area codes to look familiar on caller ID. A genuine 329 number on your screen is no guarantee the caller is in Poughkeepsie, NY or trustworthy.
