What to do about calls from 346 numbers

Before you call back

  • Debt reduction is the top named complaint here. Don't pay upfront fees for debt relief; the FTC's Telemarketing Sales Rule bans them. Talk to your lender or a nonprofit credit counselor instead. Read about debt-relief robocalls.
  • Look up the full number above. A missed call from 346 with no voicemail is usually a robocall; anyone who needs you will leave a message.
  • Block repeat callers: iPhone, Android, or your carrier's free filter (Verizon, AT&T, T-Mobile).

Report it in Texas

  • 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: Texas Attorney General.
  • Texas is one of the states that maintains its own Do Not Call registry alongside the federal National Do Not Call Registry, so telemarketers calling Texas 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.
