What to do about calls from 274 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 274 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).
