How to find a debt collector's address

The safest place to find a debt collector's mailing address is the validation notice the collector has to send you. Your credit report and your state's licensing records are good backups. Don't rely on an address from a random website, and don't send money or personal details until you've confirmed who you're dealing with.

Where to find the address

  1. The validation notice. Under federal rules, a debt collector generally has to send you a validation notice within five days of first contacting you. It lists the collector's name and mailing address, the creditor, the amount, and how to dispute. Many notices name a specific address for disputes. Use that one.
  2. Your credit report. Collection accounts on your report usually show the collector's name and contact information. Get your reports free at AnnualCreditReport.com.
  3. Your state's licensing records. Many states require debt collectors to be licensed. Your state's banking or financial regulator, or attorney general, can confirm a collector is real and give its address of record.
  4. Court papers. If you've been sued, the summons lists the plaintiff's attorney and address. Respond to the court by the deadline, not just to the collector.

Signs it may be a scam

  • They won't give you a company name, mailing address or a written notice.
  • They pressure you to pay today, by gift card, wire transfer or payment app.
  • They threaten arrest or jail.
  • The debt doesn't match anything you recognize, and they won't explain it.

Hang up and look the company up yourself. You can also report it to the Consumer Financial Protection Bureau and the FTC.

What to send: a debt validation letter

If you don't recognize the debt or think the amount is wrong, dispute it in writing within 30 days of receiving the validation notice. The collector then has to stop collecting until it sends you verification of the debt. Send your letter by certified mail with a return receipt, and keep a copy.

[Your name]
[Your address]

[Date]

[Debt collector name]
[Collector address from the validation notice]

Re: Account number [number from the notice]

To whom it may concern,

I am writing in response to your notice dated [date]. I dispute this debt and request verification under the Fair Debt Collection Practices Act.

Please send me:
- The name and address of the original creditor
- The amount owed and how it was calculated
- Proof that you are authorized to collect this debt

Until you provide verification, please stop collection on this account.

Sincerely,
[Your name]

Don't include your full Social Security number, bank details or a copy of your ID unless you've confirmed the collector is real and there's a specific reason to.

If you can't find any address

Ask the collector to mail you a validation notice, and don't pay until you get it. If the account is on your credit report and you can't reach the collector, you can dispute it directly with the credit bureau that lists it. The bureau has to investigate.

Keep a record

  • Every letter you send and receive, with dates.
  • Certified mail receipts.
  • Notes from each call: date, time, the person's name, and what was said.

If a collector breaks the rules, those records help when you file a complaint or talk with a consumer attorney.
