Is a call from 610 a scam?
Area code 610 serves Allentown and the surrounding area, so most calls are ordinary local and business traffic. As everywhere, spam and robocalls do use 610 numbers, frequently by spoofing a local-looking caller ID to boost pickup rates. The area code itself tells you nothing about who is really calling, so judge the call by what's said, not the number.
Red flags to watch for
- Pressure to act right now, or threats of arrest, fines, or service being cut off.
- Requests to pay with gift cards, wire transfer, crypto, or a payment app.
- Asking for passwords, one-time codes, your SSN, or full card/bank numbers.
- A robocall or recording, or a number that won’t let you call back.
When unsure, hang up and call the organization back on a number you look up yourself.
