Who sends it: A debt collector, in its first contact with you or within 5 days after.
What this notice is
Under federal rules, a debt collector must give you a validation notice, either in its first contact or within five days after. It must say it is from a debt collector, name the creditor, give the account number and amount, and show how the amount was reached: interest, fees, payments and credits.
It also gives a specific end date for a 30-day period when you can dispute the debt, and a section you can use to reply.
What to check
- Do you recognize the original creditor and the account?
- Is the amount right? Compare it with old statements.
- Is it someone else's debt, one you already paid, or one already settled?
- Is it very old? Some debts are too old for a lawsuit under your state's law.
- Is the collector real? Look up its name and address yourself.
What to do: dispute in writing
If you dispute in writing within the period, the collector must pause collecting the disputed amount until it sends you verification. You can still dispute after the end date, but that pause rule only covers disputes sent in time. Not disputing does not mean you admit you owe the debt.
- Before the end date on the notice, write to the collector. Say you dispute the debt and ask for verification. You can also ask for the name and address of the original creditor.
- Use the reply section of the notice, or a sample letter from consumerfinance.gov.
- Mail it in a way that gives you proof, such as certified mail with a return receipt, and keep a copy.
Before you pay anything
- Do not pay on a phone call you did not expect. Ask for the notice in writing first.
- Before paying anything on a very old debt, ask a legal aid office. In some states a payment can affect your rights.
- Social Security and other federal benefits are generally protected from most debt collectors. If a collector threatens your benefits, get legal advice.
- If you decide to pay or settle, get the agreement in writing before you pay.
How to tell a real one from a fake
A real collector gives you its name, mailing address and the original creditor, and sends this notice. Fake collectors push you to pay today, refuse to send anything in writing, or ask for gift cards or wire transfers.
Collectors are not allowed to threaten you with arrest for not paying. Report problems at consumerfinance.gov or reportfraud.ftc.gov.
