Quick answer
Verify the collector and request the required debt information before paying an unfamiliar demand.
Do now
Keep the notice and envelope. Independently verify contact details. Review the stated dispute period and send a written dispute or request through a traceable method where appropriate. CFPB describes a 30-day validation period for covered notices.
Watch for
Disputing with a collector does not answer a court lawsuit. Do not provide passwords, bank-login details, or payment to an unverified caller.
