Where is area code 657?
The 657 area code is a North American Numbering Plan geographic code serving Anaheim and the surrounding Northern Orange County region in California. Assigned by the North American Numbering Plan Administration in 2008, it currently serves approximately 2,000,000 residents on the Pacific Time (PT) (UTC-8 / UTC-7 DST). It shares geography with overlay code 714.
Cities served by the 657 area code
The 657 area code covers 5 major cities and towns across the Northern Orange County region:
| City | State |
|---|---|
| Anaheim | CA |
| Santa Ana | CA |
| Garden Grove | CA |
| Orange | CA |
| Fullerton | CA |
Businesses across Anaheim and surrounding cities use 657 numbers to project local presence and lift call answer rates. Industry studies of local presence dialing consistently report answer-rate gains of 20–40% over toll-free or out-of-area numbers — a caller ID that matches the recipient's region looks familiar and gets picked up.
657 area code time zone and business hours
The 657 area code is in the Pacific Time (PT) zone (UTC-8 / UTC-7 DST). Standard business hours in 657 run 9 AM to 5 PM PT.
If you're calling into 657 from a different time zone, factor in the offset. For example, an Eastern Time business calling 657 at 9 AM ET reaches Anaheim at 6 AM PT — likely outside standard business hours.
History of the 657 area code
The 657 area code was introduced in 2008 when the North American Numbering Plan was first deployed. As Anaheim grew and number demand increased, overlay code 714 was added to serve the same geographic region — a common solution that avoids forcing existing subscribers to change their numbers.
Is the 657 area code safe? Spam and scam calls
657 is a legitimate geographic area code for Anaheim — it is not a scam code or a premium-rate prefix, and a call from a 657 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 657 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 Anaheim 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 657 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 657 area code number for your business?
Getting a 657 number gives your business three measurable advantages over a toll-free or out-of-area number:
- Local trust signal. Customers in Anaheim recognize 657 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 Anaheim and the broader Northern Orange County can advertise a local number across print, radio, billboards, and digital channels for higher conversion than a national 800 number.
For businesses in Anaheim and surrounding cities, top industries that benefit from local 657 presence include Tech, Entertainment, and Healthcare. DialPhone's AI receptionist is available for every 657 number — never miss a call, even after standard business hours.

AI receptionist for 657 area code businesses

How We Tested
DialPhone re-verifies every area code page every 90 days. Area code geography, timezone, and overlay data come from the official North American Numbering Plan Administration (NANPA) database. Pricing reflects the published DialPhone plan tiers — see the pricing page for current details. Number availability varies; check the DialPhone signup flow for live inventory in the 657 region.
What We Don't Like
- Number availability is finite. Popular Anaheim area codes can be inventory-constrained — request specific vanity patterns early.
- Porting timing varies. Most 657 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.
