Common Scams Reported From Area Code 618

Neighborhood Spoofing

Scammers forge caller ID so a robocall appears to come from a local 618 number—sometimes matching your own first six digits—to boost the odds you answer. The real caller is often overseas or using an auto-dialer. If a “local” 618 call opens with a recording or a stranger asking for payment or personal data, hang up.

Phishing, Bank Impersonation & Impostor Scams

Fraudsters posing as your bank’s fraud department, the IRS, Social Security, or a utility company call from a 618 number claiming urgent action is required. They pressure you to “verify” account numbers, passwords, or one-time codes, or to pay with gift cards or wire transfer. Real institutions never demand those.

Text Message (SMS) / Smishing Alerts

Smishing texts from 618 numbers pose as package couriers, banks, or toll agencies with a link to “resolve” an issue. The links lead to fake login pages that harvest credentials. Do not tap links in unexpected texts; open the company’s app or type its website manually instead.

How to Identify & Verify Unknown Callers From 618

Let it ring. Legitimate callers leave a voicemail; most scam auto-dialers do not.
Search the number. Paste the full 10-digit number into a search engine or a reverse-lookup site to see if others reported it as spam.
Check the location. A real 618 call should relate to southern Illinois. Compare it with our area code 618 reference and the Belleville area code guide.
Call back on an official number. If a caller claims to be your bank or a government agency, hang up and dial the number printed on your card or the agency’s official website—never the number that called you.
Never share codes. No legitimate caller needs a one-time passcode, PIN, or password read aloud.
