What Is a Debt Collector?
A debt collector is someone who chases money you owe to a different company. That is the short version. The law that covers most of them is the Fair Debt Collection Practices Act, and it treats a company collecting its own bills differently than a company collecting yours for someone else.

Outside Collectors vs. the Company You Borrowed From
Say you fell behind on a credit card. At some point the bank may hand the account to an outside company, or sell it outright. That outside company is a third-party collector. Those are the ones the FDCPA was written for, and they have the most rules to follow.
The bank's own collections staff is a different story. When the original lender calls you about its own account, federal collection law usually does not apply to them the same way. That does not mean they can do anything they want. Many states have their own rules that cover every caller. And if an in-house team uses a name that makes it sound like a separate business, some courts have said the FDCPA applies anyway. If you are not sure who you are talking to, read original creditors vs. collectors. Knowing which one you have changes what you can push back on.
Three Kinds of Outside Collectors
- Collection agencies. They do not own your debt. They work on commission and keep a cut of whatever they get you to pay. More on how they work in collection agencies.
- Debt buyers. They bought your account, often for pennies on the dollar, and now the money comes to them. That also means they may have thin paperwork. See debt buyers.
- Law firms that collect. A letter on law firm letterhead feels scarier, but a firm that collects debts for a living is still a debt collector under the FDCPA. The same rules apply to them.
What Every Covered Collector Has to Do
There are limits on when they call. They cannot harass you or threaten you. They have to give you the debt in writing if you ask, and they cannot lie about who they are, how much you owe, or what they can do to you in court. The full list is in our FDCPA guide.
Here is what that looks like in real life. An outside collector generally cannot call you before 8 a.m. or after 9 p.m. your time. Our page on debt collection calls covers how often they are allowed to dial. They have to stop calling you at work once you tell them not to. And they cannot say they are going to sue you when they have no plan to. If one of them crosses a line, you can report it. Our consumer rights guide walks through filing a complaint, and debt collector harassment shows you what counts.
Where People Get Caught
- Thinking every caller is covered by the FDCPA. Your original lender collecting its own account usually is not, though other laws still apply to them.
- Not asking who is calling. You have the right to a clear company name, and to get the debt in writing when you ask for it.
- Mistaking a collection letter for a lawsuit. A letter is not a court case. If you actually get served, read debt lawsuits right away, because your time to answer is short.
FAQ
Is a debt collector the same thing as a debt buyer?
Not always. A debt buyer is one kind of debt collector, the kind that bought and now owns your account. Plenty of other collectors never own the debt. They just work it for a fee.
Can my bank's own collections team call at any hour?
The federal time limits usually do not apply to the original lender. But a lot of states set their own hours for everyone who calls, including the bank. Check your state rules.
How do I tell what kind of collector I have?
Look at the company name on the letter, or ask for it on the phone, then compare it to the lender you first borrowed from. If the names do not match, you are dealing with an outside collector. See original creditors vs. collectors.
