Is a call from 504 a scam?
The area code alone says nothing about the caller. It shows where the number was set up. It does not show who is calling or where they are. The FTC says scammers can make any name or number show up on caller ID. This is called spoofing, and it can make a call look local when it comes from anywhere in the world.
Signs of a phone scam, from the FTC:
- The caller says you won a prize, but you have to pay to get it.
- The caller says you will be arrested or fined unless you pay right away. Real law enforcement and federal agencies do not call and threaten you.
- The caller insists you pay by gift card, wire transfer, cryptocurrency or a payment app.
- The caller says they are from a government agency and asks for your Social Security number.
What to do:
- If you get a robocall, hang up. Do not press any number, which could lead to more robocalls.
- Ask your phone carrier what call blocking it offers.
- Report unwanted calls at DoNotCall.gov. If you lost money, report it at ReportFraud.ftc.gov.

Our API lines are real T-Mobile mobile numbers for texts, or for texts and calls over SIP, rented by the month. Add "area_code": "504" to an order to ask for 504 numbers.
The area code is a request and is not guaranteed. Numbers come from our stock and from the carrier, so some can have another area code. If the carrier cannot fill the request within about an hour, we send numbers from other area codes.
