You can legally stop Capital One calls from 800-955-6600 by revoking consent, sending a cease letter by certified mail, and documenting violations for potential TCPA claims worth up to $1,500 per call.

File Your Answer

The phone rings. Again. Same number: 800-955-6600. You answer—automated voice from Capital One. You hang up. You call back,they deny knowing why you were contacted. You're stuck in a loop that feels designed to wear you down.

This isn't in your head. Capital One's dialing system operates on volume, not precision. Their records show you owe $47.82. Or maybe nothing at all. Either way, the calls keep coming. Good news: You can shut this down. Federal law gives you the tools. You just need to use them correctly.

Who's Behind 800-955-6600

800-955-6600 belongs to Capital One, the Richmond-based bank that manages over 100 million credit card accounts. They handle collections in-house, which means the person calling isn't a third-party debt collector,it's Capital One chasing its own debt.

Why does this matter? Because the rules are slightly different. Third-party collectors fall under the Fair Debt Collection Practices Act (FDCPA). Capital One, as your original creditor, doesn't,at least not for this particular debt. But they still must follow the Telephone Consumer Protection Act (TCPA) and state harassment laws.

The Consumer Financial Protection Bureau logged 38,742 complaints against Capital One in the past three years. The top issue: repeated calls about accounts consumers either don't recognize or already paid. The Better Business Bureau shows 10,214 closed complaints over the same period. Most cite the same problem,calls that won't stop, even after multiple requests.

Why Capital One Keeps Calling

Capital One uses predictive dialers. These systems auto-dial hundreds of numbers per hour. If you don't answer, it marks you for a callback. If you do answer and hang up, same thing. The system interprets silence as "try again."

Here's what usually triggers the calls:

  • Missed payment: You're 30+ days late on a credit card or loan.
  • Underpayment: You sent $150 on a $175 minimum payment.
  • Account closed with a balance: You closed your card but still owe $89.
  • Wrong number: The previous owner of your phone number owed Capital One.
  • Data error: Their system tagged your number by mistake.

If you genuinely owe money, ignoring the calls won't make the debt disappear. If you don't owe anything, ignoring them won't fix their records. Either way, you need to act.

How to Stop the Calls Immediately

Pick up the next call from 800-955-6600. Say this: "I revoke consent for Capital One to contact me by phone. Send all communication in writing to [your mailing address]. Remove this number from your system."

The agent may push back. They'll say, "We need to discuss your account." Stand firm. You're exercising your right under the TCPA, which requires your prior express consent for automated calls. You gave that consent when you opened the account. You can withdraw it at any time.

Take notes: date, time, the agent's name or ID number. Write down exactly what you said and what they said. If the calls continue, this becomes evidence.

Step 2: Send a Written Cease Communication Request

Follow up in writing. Mail a letter to Capital One at 15000 Capital One Drive, Richmond, VA 23238. Keep it short:

"I revoke consent for Capital One to contact me by telephone at [your number]. Communicate only via U.S. Mail at [your address]. This is not a refusal to pay any valid debt. I am exercising my rights under the TCPA."

Send it certified mail with a return receipt. Cost: around $8. Proof if they sue you or you sue them: priceless.

Once Capital One receives your letter, they can only call to confirm receipt of your request or notify you of specific legal actions (like a lawsuit). Anything beyond that violates federal law.

Step 3: Register with the National Do Not Call Registry

Go to donotcall.gov or call 888-382-1222. Registration is free. It won't stop Capital One immediately,creditors calling about existing accounts are exempt,but it creates another layer of legal protection if they keep calling after you've revoked consent.

If Capital One calls 31 days after you register and you've sent a cease letter, you can file a Federal Trade Commission complaint. Penalties start at $500 per violation.

Step 4: Block the Number

On an iPhone: Open the Phone app, tap the "i" next to 800-955-6600, scroll down, select "Block this Caller."

On Android: Open the Phone app, tap "Recent," press and hold 800-955-6600, select "Block number."

Your carrier may offer additional blocking tools. AT&T's Call Protect, Verizon's Call Filter, and T-Mobile's Scam Shield are all free for basic blocking. Blocking doesn't stop the legal debt (if one exists), but it stops the noise.

What If the Calls Continue

You sent the letter. You revoked consent. The calls keep coming. Now what?

Document every call. Note the date, time, and whether it was a live person or a recording. After the third call following your cease request, you have grounds for a TCPA lawsuit. Statutory damages are $500 per call. If the court finds the violations were willful, that triples to $1,500 per call.

Five unwanted calls after your cease letter? That's $7,500 in potential damages. Ten calls? $15,000. Capital One knows this. Most cases settle quickly once you file.

You don't need a lawyer to file a TCPA claim, but it helps. Many consumer rights attorneys work on contingency,you pay nothing upfront, and they take a percentage if you win. Start with a free consultation. Check consumeradvocates.org for attorneys in your state.

If You Actually Owe Capital One Money

Stopping the calls doesn't erase a valid debt. Capital One can still report late payments to credit bureaus, charge off the account, and eventually sue. Once a lawsuit lands, the stakes jump. A judgment means wage garnishment, frozen bank accounts, and a 7-year credit report scar.

If you owe less than $5,000 and can scrape together 40-60% of the balance, call Capital One's settlement line at 800-981-9195. Say you want to settle. They'll often accept a lump sum. Get the settlement terms in writing before you pay a dime.

If you're drowning in multiple debts, bankruptcy might be the better move. Chapter 7 wipes out unsecured debts like credit cards in about four months. Chapter 13 lets you repay what you can afford over 3-5 years. Either way, the calls stop the day you file. Check if you qualify for bankruptcy relief here.

When Capital One Has the Wrong Number

You've never had a Capital One account. The calls started when you got a new phone number. This happens constantly. Capital One's system still has the previous owner's number flagged.

Call back at 800-227-4825 (Capital One's customer service line). Explain you're not the person they're trying to reach. They'll ask for the account holder's name. If they give it to you and it's not you, tell them to remove your number immediately.

If they refuse or the calls continue, send a written dispute under the Fair Credit Reporting Act (FCRA). Even though Capital One isn't a credit bureau, the FCRA's accuracy requirements apply to information they report about you. State clearly: "I have no relationship with Capital One. Remove my phone number from all accounts."

Wrong-number calls after a written dispute? That's a potential TCPA violation, and courts tend to side with consumers in these cases.

Filing Complaints That Actually Work

If Capital One ignores your cease letter, file complaints with:

  • Consumer Financial Protection Bureau: consumerfinance.gov/complaint. The CFPB forwards complaints to Capital One and requires a response within 15 days. They track patterns. Enough complaints trigger investigations.
  • Federal Communications Commission: consumercomplaints.fcc.gov. The FCC enforces the TCPA. They can fine companies up to $10,000 per violation.
  • Your state attorney general: Most states have consumer protection divisions. Google "[your state] attorney general consumer complaint." Some states (California, New York, Texas) aggressively prosecute harassment cases.

Complaints don't stop calls instantly, but they build a paper trail. If you later sue Capital One, that trail shows a pattern of abuse.

What Capital One Might Do Next

You stopped the calls. Capital One still has options. They may:

  • Send letters: You asked them to stop calling, not writing. Expect mail. Don't ignore it. If they're threatening a lawsuit, you need to respond.
  • Report to credit bureaus: Late payments, charge-offs, and collections hit your credit report. Check your report at annualcreditreport.com. If the information is wrong, dispute it in writing.
  • Sell the debt: Capital One may sell your account to a third-party collector. Once that happens, the FDCPA kicks in, giving you more legal protections. Demand validation of the debt in writing before you pay.
  • Sue you: If you owe more than $1,000, Capital One might file a lawsuit. You'll be served with a summons and complaint. You have 20-30 days to respond (varies by state). Miss that deadline, and Capital One wins by default.

If you get sued, don't panic. Answer a few quick questions to see your options,including whether bankruptcy can stop the lawsuit before judgment.

One Final Thing

Capital One's dialing system is aggressive, but it's not unstoppable. Revoke consent. Send a cease letter. Document everything. If they ignore you, the law is on your side. You're not powerless here. You're just dealing with a machine that doesn't care until you force it to stop.

Frequently Asked Questions

Is 800-955-6600 a scam or really Capital One?

It's really Capital One. The number belongs to their automated collections system. Scammers occasionally spoof it, but if you call 800-227-4825 (Capital One's verified customer service line), they can confirm if the original call was legitimate.

Can I sue Capital One if they keep calling after I send a cease letter?

Yes. The TCPA allows you to sue for $500 per unwanted call after you revoke consent. If the court finds the violations were willful, damages increase to $1,500 per call. Many consumer attorneys handle these cases on contingency, so you pay nothing upfront.

Will blocking 800-955-6600 stop Capital One from collecting the debt?

No. Blocking stops the calls from reaching you, but Capital One can still report to credit bureaus, sell the debt, or sue. If you owe money, negotiate a settlement or explore bankruptcy. If you don't owe anything, dispute the debt in writing and demand proof.

What if Capital One is calling me about someone else's debt?

Call 800-227-4825 and explain you're not the account holder. If the calls continue after you notify them in writing, that's a potential TCPA violation. You may be entitled to damages for each call made to the wrong person after you disputed the debt.

Does registering with the National Do Not Call Registry stop creditor calls?

Not immediately. Creditors calling about existing debts are exempt from Do Not Call rules. But if you've also sent a cease letter and revoked consent under the TCPA, the registry adds another layer of legal protection if Capital One ignores your request.
