Is the 571 area code safe? Spam and scam calls

571 is a legitimate geographic area code for Arlington — it is not a scam code or a premium-rate prefix, and a call from a 571 number is most likely a genuine local caller. The risk is not the area code itself but a tactic called neighbor spoofing: scammers fake their caller ID so an unwanted call appears to come from your own area code, because people answer familiar numbers more readily.

If you get an unexpected 571 call, a few signals point to a likely scam — a pre-recorded message, urgent pressure to act now, a demand for payment by gift card or wire transfer, or anyone asking for passwords, Social Security, or account numbers. Let suspicious calls go to voicemail, never share personal information, and report fraud to the FTC at reportfraud.ftc.gov.

The FCC consumer guide on spoofing explains your rights under the Truth in Caller ID Act. A real Arlington business will leave a clear voicemail and will not pressure you.

US carriers verify caller ID with the STIR/SHAKEN framework, which flags many spoofed numbers as "Spam Likely" before they ring. DialPhone 571 numbers are registered for STIR/SHAKEN attestation, so calls from your business are verified as genuine and reach customers without a false spam label. See the DialPhone guide to VoIP security for more.

Why get a 571 area code number for your business?

Getting a 571 number gives your business three measurable advantages over a toll-free or out-of-area number:

1. Local trust signal. Customers in Arlington recognize 571 as their home area code. Caller ID matching builds immediate credibility for service businesses, sales outreach, and patient communication.
2. Higher answer rate. Calls from a familiar local area code are answered far more often than unknown or toll-free numbers — industry measurements of local presence dialing put the lift at 20–40%, which matters most for outbound sales, appointment confirmations, and time-sensitive service callbacks.
3. Targeted marketing. Businesses serving Arlington and the broader Northern Virginia can advertise a local number across print, radio, billboards, and digital channels for higher conversion than a national 800 number.

For businesses in Arlington and surrounding cities, top industries that benefit from local 571 presence include Professional Services, Healthcare, and Retail. DialPhone's AI receptionist is available for every 571 number — never miss a call, even after standard business hours.

What to know before getting a 571 number

• Porting timing varies. Most 571 ports complete in 2-5 business days; complex multi-line legacy contracts can take 7-10.
• HIPAA tier required for healthcare. The Core $24 plan doesn't include a BAA — healthcare users need Advanced ($34) or above.
