Carriers operating in 504
NANPA has assigned 563 504 prefixes (NPA-NXX central-office codes) across 6 rate centers: 37% to wireless carriers, 61% to landline and VoIP operators; 66% are pooled blocks shared by several carriers. 4 prefixes were assigned in the last 12 months (newest 2026-09-16).

What to do about calls from 504 numbers
Before you call back
- Impostor (government, business, family) is the top named complaint here. Hang up and call the agency, bank or relative back on a number you already know. Government agencies don't demand payment by gift card, wire transfer or crypto. Read about Social Security impostor calls and fake bank fraud calls.
- Look up the full number above. A missed call from 504 with no voicemail is usually a robocall; anyone who needs you will leave a message.
- If it looks like a neighbor's number, it may be spoofed. See calls from your own area code.
- Block repeat callers: iPhone, Android, or your carrier's free filter (Verizon, AT&T, T-Mobile).
Report it in Louisiana
- Unwanted sales calls and robocalls: donotcall.gov (FTC). Scams and fraud: ReportFraud.ftc.gov.
- Spoofing, texts and call-blocking problems: FCC consumer complaints.
- State complaints: Louisiana Attorney General.
- Louisiana is one of the states that maintains its own Do Not Call registry alongside the federal National Do Not Call Registry, so telemarketers calling Louisiana numbers are expected to check both lists. Registering on the federal list at donotcall.gov is free and never expires; the state list is administered separately and may have its own registration process and renewal period.
