Is area code 738 a scam?
30 FTC Do Not Call complaints named a 738 caller ID between 2026-09-28 and 2026-10-30 – 0.9 a day, which puts 738 396th of the 422 codes with five or more complaints in that window, in the quieter half of the complaint table. That figure counts what the caller ID displayed, not where the call came from. Faking caller ID is trivial and routine: a spam operation picks a number that looks local to whoever it is dialling, because local-looking calls get answered more often. So a high count means the code is imitated often. Nothing here identifies a caller. We publish counts for the code, never names or addresses, and a report about a single number is a user's claim rather than a finding.
Check the actual number instead
The code tells you almost nothing about one call. A number-level lookup shows the carrier, the line type and any reports we hold for that number – and never a name or an address.
What to do about calls showing 738
- Let an unexpected call go to voicemail. Answering confirms the number is live and tends to bring more calls.
- Do not dial back a missed number you do not recognise. If the call claimed to be your bank or a government office, look their number up yourself and call that.
- Turn on your carrier's spam filtering and your phone's “silence unknown callers”. Blocking individual numbers achieves little, because the displayed numbers rotate constantly.
- Report unwanted sales calls at donotcall.gov and fraud at reportfraud.ftc.gov. Those filings are what this page counts.
- If your own number is the one being spoofed, there is nothing to take down here: this site publishes complaint counts for the code, never claims about individual numbers. Report the spoofing to your carrier – they can see the originating traffic, and we cannot.
Frequently asked
Is area code 738 a scam?
The code is not – 738 is a legitimate code serving California, and real people and businesses have numbers in it. What is true is that it appeared in 30 FTC complaints in the 33 days to 30 October 2026, 396th of 422 ranked codes. Judge the specific number, not the three digits.
Why do I keep getting calls from 738 numbers?
Most likely neighbour spoofing: the dialler fakes a number that shares your area code – or one from a place you plausibly know – so the call looks local. The numbers rotate, which is why blocking one does little. Your carrier's own spam filtering and your phone's silence-unknown-callers setting do more.
Should I answer a call from 738?
If you are not expecting it, let it go to voicemail. Answering confirms a live number and tends to bring more calls. Never return a missed call from a number you do not recognise by dialling it back – call the organisation on a number you look up yourself.
How do I report a spam call from 738?
Report unwanted sales calls at donotcall.gov and anything involving fraud at reportfraud.ftc.gov. Those complaints are the source of the counts on this page, so reporting is what makes the next number here more accurate.
Can a call show a 738 number that does not exist?
Yes. Only 30 of the 786 possible blocks are assigned in 738, and within an assigned block plenty of numbers are unissued. Caller ID carries whatever the caller puts in it.
