610 Area Code — Allentown, Pennsylvania

Area Code Overview

Area code 610 was created in 1994 when the original 215 code split to handle explosive suburban growth. It covers Chester County, Delaware County, and the western portions of Montgomery County — a corridor commonly known as the Main Line. Communities include Ardmore, Wayne, Media, West Chester, Exton, and Phoenixville. The area is one of the most affluent suburban corridors in the northeastern United States, anchored by long-established professional class residents, major health systems, and a dense concentration of regional corporate campuses.

Chester County and Delaware County together have some of the highest median household incomes in Pennsylvania. The region's economic base includes healthcare (Jefferson Health, Tower Health, Crozer Health), financial services, pharmaceutical research and development, and technology. A large population of retirees and homeowners with significant property equity makes 610 territory a frequent target for financial and utility fraud that exploits the area's comparatively high wealth.

Scam Patterns in 610

PECO Energy Disconnection Fraud
PECO — the Exelon subsidiary that serves as the dominant electric utility for southeastern Pennsylvania, including all of Delaware County and Chester County — is routinely impersonated in texts sent to 610 residents. The scam text typically claims the recipient's account is past due and that service will be disconnected within hours unless immediate payment is made through a link or prepaid card. PECO does not demand same-day payment via text link and will not require gift cards. Legitimate PECO disconnection notices arrive by mail and through the account portal, with advance notice required under Pennsylvania Public Utility Commission rules. The impersonation is effective because PECO is genuinely the only electric provider for most of the region — recipients know their utility is PECO, which lends the text false credibility. Seasonal spikes occur in summer (peak air conditioning billing) and winter (heating season) when consumers are primed to expect higher bills.

Main Line Health System and Hospital Billing Fraud
The Main Line corridor is served by several major regional health systems — Jefferson Health (which absorbed Main Line Health), Tower Health (Brandywine Hospital, Phoenixville Hospital), and Crozer Health (now part of Prospect Medical) — with facilities throughout Delaware and Chester counties. Scam texts impersonate billing departments from these health systems, claiming an outstanding balance must be resolved immediately to avoid collections or that insurance has rejected a claim requiring patient co-payment. Because many 610 residents have recently received care at these facilities, they are conditioned to expect billing communications. The texts link to convincing imitation billing portals that harvest credit card and insurance information. Crozer's financial difficulties in recent years have increased patient anxiety around billing, making the scam more effective in Delaware County specifically. Verify any medical bill by calling the number on your explanation of benefits or the hospital's main switchboard.

Chester County and Delaware County Property Tax Assessment Dispute Fraud
Chester County and Delaware County conduct periodic property tax reassessments, and both counties have formal appeal processes administered through their respective Board of Assessment Appeals. Scam texts target homeowners claiming their property assessment has been flagged for review and that a "processing fee" or "consultant deposit" is required to lock in a reduction, or that failure to respond will result in a retroactive tax increase. The fraud exploits real anxiety around reassessments — Chester County completed a major reassessment cycle in recent years, and Delaware County conducted a countywide reassessment that produced significant changes for many homeowners. Legitimate assessment appeal processes do not require upfront payment via text. Contact the Chester County or Delaware County Assessment office directly through their official government websites.

VoIP and Spoofing Risk Assessment

Risk Level: MOD

610 retains a higher proportion of landline and long-established business numbers than Philadelphia's overlay codes, which moderates the raw VoIP density. However, the code serves a large enough territory — and a sufficiently wealthy residential base — that it remains an attractive spoofing target. Scam operators spoof 610 numbers to appear as a local suburban call to Main Line residents who are more likely to answer or engage with what appears to be a familiar local number. The PECO and healthcare billing patterns are well-documented in Pennsylvania consumer protection reporting.

What To Do If You Receive a Text From a 610 Number

1. Do not click any link in an unsolicited text claiming to be from PECO, a hospital billing department, or a county government office. Navigate directly to the official website by typing the address yourself.
2. Look up the number at Who Sent That Text Message to check for prior reports and to identify the line type and carrier before responding.
3. If the text references a utility or medical bill, verify your account status through the provider's official app or by calling the number printed on your last paper statement. See our guide on identifying spoofed text messages.
4. Report the text by forwarding to 7726 (SPAM). File with the FTC at reportfraud.ftc.gov. Report utility impersonation to the Pennsylvania Office of Consumer Advocate at consumer.pa.gov.

Frequently Asked Questions

What area code is 610?
Area code 610 serves the Philadelphia western suburbs — Chester County, Delaware County, and portions of western Montgomery County. It was created in 1994 as a split from the original 215 code and covers communities including West Chester, Media, Ardmore, Wayne, and Exton along the Main Line corridor.

Is a text from a 610 number a scam?
610 is a legitimate area code used by millions of suburban Philadelphia residents and businesses. However, 610 numbers are spoofed in targeted scam campaigns — particularly PECO utility disconnection fraud and hospital billing impersonation — because residents recognize the area code as local. An unknown 610 text requesting payment or personal information should be verified before any action is taken.

How do I report a PECO scam text in the 610 area?
Forward the text to 7726 (SPAM) to report it to your carrier. File a complaint with the FTC at reportfraud.ftc.gov. You can also report utility impersonation to the Pennsylvania Public Utility Commission at puc.pa.gov or call PECO directly at the number on your utility bill to confirm your account status.
