Constant calls from 800-955-6600 can disrupt your day. You answer once and hear a prerecorded message claiming to be Capital One. You ignore it, but the calls keep coming.

You have the power to stop these calls. Here’s how to take control.

Respond to Northland Group

Who Calls From 800-955-6600?

The prerecorded message says Capital One, but the number belongs to Northland Group. Northland Group is a debt collection agency working for Capital One.

Northland Group is legitimate, not a scam. The company either collects debts on Capital One’s behalf or purchased your debt outright. Either way, they believe you owe money.

Should You Call Northland Group Back?

Never respond to robocalls directly. You can contact Northland Group’s parent company, Radius Global Solutions, at 888-287-5711.

Calling them serves two purposes. You learn exactly why they’re contacting you. You can also request they stop calling you entirely.

What to Do After Receiving These Calls

Stopping the calls doesn’t eliminate your debt. You need a plan to address the underlying issue.

Request Debt Validation

Send a written request asking Northland Group to verify the debt. You need three pieces of information:

  • The debt collection agency’s name
  • The original creditor’s name
  • Your original debt amount

The company must provide this information. Validation confirms whether Northland Group legally owns your debt and the amount is accurate.

Respond to the Collector

You have options once you receive validation. Dispute the debt if you find errors or inaccuracies. Negotiate a settlement if the debt is valid.

Many collectors accept less than the full amount as a lump sum. Settling quickly helps you rebuild your credit faster.

If Northland Group sues you over the debt, our partner Solo can help you respond with a proper legal Answer.

The National Do Not Call Registry doesn’t protect you from legitimate debt collectors. But the Fair Debt Collection Practices Act (FDCPA) does.

Debt collectors cannot:

  • Contact your friends, family, or coworkers about your debt
  • Call you more than once per day
  • Call you after receiving a Cease and Desist letter
  • Call you before 8 a.m. or after 9 p.m.
  • Refuse to validate your debt when requested

Northland Group must follow these rules. Report violations to the FTC at 877-382-4357 or online at ftc.gov.

You can also file complaints with the Consumer Financial Protection Bureau. Call 855-411-2372 or visit their website to submit a report.

Send a Cease and Desist Letter

A Cease and Desist letter legally requires Northland Group to stop contacting you. The company must honor this request once it receives your letter.

Keep in mind that stopping communication doesn’t erase your debt. Northland Group can still pursue collection through a lawsuit.

If they sue you, you must file a legal Answer. Your Answer states your defenses and shows your willingness to settle or fight in court.

Real Example: Stopping Northland Group Calls

Sherri received daily calls from 800-955-6600. The prerecorded messages claimed to be from Capital One.

She didn’t trust the callback number provided. Instead, Sherri called Northland Group directly at 888-287-5711. She requested debt validation in writing.

After receiving validation, Sherri confirmed the debt was legitimate. She sent a Cease and Desist letter to stop the calls. Then she set up a payment plan with Northland Group.

The calls stopped immediately. Sherri addressed her debt on her terms.

What Happens If You Get Sued

Northland Group may file a lawsuit if you don’t respond. You’ll receive a court summons and complaint.

You must respond within the deadline stated in your summons. Most states give you 20-30 days to file an Answer.

Your Answer should include your defenses. Common defenses include statute of limitations, mistaken identity, or incorrect debt amount.

Filing an Answer protects you from a default judgment. Default judgments allow creditors to garnish your wages or freeze your bank accounts.

Our partner Solo helps you draft and file your Answer correctly. The service ensures you meet court deadlines and include proper defenses.

How to Negotiate a Settlement

You can often settle debt for less than you owe. Collectors prefer quick payment over lengthy court battles.

Start by offering 30-50% of the total debt. Many collectors accept this amount as full payment.

Get any settlement agreement in writing before paying. The agreement should state the debt will be satisfied in full.

Never give collectors direct access to your bank account. Pay with a cashier’s check or money order instead.

Protecting Yourself From Future Calls

Document every interaction with Northland Group. Keep records of call dates, times, and what was discussed.

Send all correspondence via certified mail with return receipt. You’ll have proof the company received your letters.

Save copies of all debt validation requests and responses. These documents become evidence if you need to file a complaint.

You have rights under federal law. Use them to stop harassment and resolve your debt fairly.
