Businesses across New Brunswick and surrounding cities use 848 numbers to project local presence and lift call answer rates.

848 area code time zone and business hours
The 848 area code is in the Eastern Time (ET) zone (UTC-5 / UTC-4 DST). Standard business hours in 848 run 9 AM to 5 PM ET.
If you're calling into 848 from a different time zone, factor in the offset. For example, an Eastern Time business calling 848 at 9 AM ET reaches New Brunswick at local time — likely outside standard business hours.
History of the 848 area code
The 848 area code was introduced in 2009 when the North American Numbering Plan was first deployed. As New Brunswick grew and number demand increased, overlay code 732 was added to serve the same geographic region — a common solution that avoids forcing existing subscribers to change their numbers.
Is the 848 area code safe? Spam and scam calls
848 is a legitimate geographic area code for New Brunswick — it is not a scam code or a premium-rate prefix, and a call from a 848 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 848 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 New Brunswick 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 848 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 848 area code number for your business?
Getting a 848 number gives your business three measurable advantages over a toll-free or out-of-area number:
- Local trust signal. Customers in New Brunswick recognize 848 as their home area code. Caller ID matching builds immediate credibility for service businesses, sales outreach, and patient communication.
- 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.
- Targeted marketing. Businesses serving New Brunswick and the broader Central New Jersey can advertise a local number across print, radio, billboards, and digital channels for higher conversion than a national 800 number.
For businesses in New Brunswick and surrounding cities, top industries that benefit from local 848 presence include Professional Services, Healthcare, and Retail. DialPhone's AI receptionist is available for every 848 number — never miss a call, even after standard business hours.

What We Don't Like
- Number availability is finite. Popular New Brunswick area codes can be inventory-constrained — request specific vanity patterns early.
- Porting timing varies. Most 848 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.
