What Debt Collectors Can and Can't Legally Do in the US (FDCPA Explained)

Federal law sets real limits on how a debt collector can contact and treat you.

Getting a call or letter from a debt collector is uncomfortable, but it doesn't mean you're without options or rights. Federal law spells out, in specific terms, what a collector can and can't do, and knowing those rules changes the conversation.

The law that governs this: the FDCPA

The Fair Debt Collection Practices Act (FDCPA) is the federal law that regulates third-party debt collectors — companies that buy or are hired to collect debt someone else originally lent. It doesn't apply in the same way to the original creditor collecting its own debt directly, though many states have their own laws that extend similar protections there too.

What a collector legally cannot do

Call before 8 a.m. or after 9 p.m. your local time, unless you've agreed to it.
Contact you at work after you've told them, verbally or in writing, that your employer prohibits it.
Use threats, obscene language, or repeated calls intended to harass or annoy you.
Threaten arrest or legal action they don't genuinely intend to take, or that isn't legally possible for that kind of debt.
Discuss your debt with your employer, neighbors, or most family members, beyond confirming your contact information.
Continue contacting you after you've sent a written request to stop, except to confirm they've received it or to notify you of specific legal action.
Misrepresent the amount you owe, or claim to be a government agency when they aren't.

What they can do

Collectors can call you, send letters, and pursue legitimate legal action, including suing you for the debt if it's within the statute of limitations for your state. They're required to send a written notice within five days of first contact stating the amount owed, the name of the original creditor, and your right to dispute the debt. That written validation notice is worth keeping.

Your right to dispute the debt

If you're not sure the debt is yours, or the amount looks wrong, you have 30 days from the validation notice to send a written dispute. Once you do, the collector has to stop collection activity until they provide proof of the debt. This single step catches a surprising number of errors — debts that were already paid, debts past the statute of limitations, or debts that belong to someone else with a similar name.

The statute of limitations matters more than it seems

Every state sets a time limit on how long a creditor or collector can sue you over unpaid debt, typically three to six years depending on the state and the type of debt. Once that period passes, the debt is often called "time-barred." Importantly, making a payment or even verbally acknowledging the debt can sometimes restart that clock in some states, which is why it's worth checking the date of your last payment before you say anything on a call.

Medical and student debt collectors follow slightly different rules

Medical debt collectors are still bound by the FDCPA, but credit reporting rules now treat paid and small unpaid medical collections more leniently than other debt, so it's worth confirming a collector's reporting practices directly — see how to negotiate medical debt. Federal student loan default is handled through your loan servicer or the Department of Education rather than a typical third-party collector in the first instance, with its own separate process — see the full options guide, which covers student loan-specific programs.

How to put a stop to contact

You can send a written "cease contact" letter, by mail, ideally with delivery confirmation, telling the collector to stop contacting you. They're allowed one more contact to confirm they've received it or to tell you they're taking a specific action, like filing a lawsuit, but otherwise the calls and letters should stop. This doesn't erase the debt — it's still owed, and it can still be reported or pursued through legal action — but it does stop the daily pressure while you figure out your next step.

If a collector breaks these rules

You can file a complaint with the Consumer Financial Protection Bureau or your state attorney general's office, and in some cases you may be able to sue the collector directly for FDCPA violations. Keep a simple log of dates, times, and what was said on every call — that record is often what makes a complaint or a legal claim credible.

What to do with the validation notice

Keep the written validation notice you receive within the first five days of contact. It should list the amount owed, the name of the original creditor, and a clear statement of your right to dispute the debt within 30 days. If a collector calls before sending that notice, you can still ask for it in writing before discussing the debt further — you're allowed to ask, and a legitimate collector will comply without pushback.

Text messages, email and social media contact

Newer rules extend similar protections to text messages, emails and, in limited circumstances, social media messages. Collectors generally need your consent to contact you by text or email, and any electronic message has to include a way to opt out. If you're being messaged in ways that feel excessive or that you never agreed to, that's worth raising in a complaint as well.

A short, factual complaint filed with the Consumer Financial Protection Bureau usually takes ten minutes and creates a paper trail that regulators, and if needed an attorney, can use later.

What happens if you're sued over a debt

If a creditor or collector files a lawsuit, you'll receive a summons, and it's important not to ignore it, even if you believe the debt is wrong or too old to collect. Failing to respond by the deadline listed can result in a default judgment against you automatically, which can lead to wage garnishment or a bank account levy depending on your state's rules. Responding, even with a simple written answer, preserves your right to raise defenses like the statute of limitations having passed.

Getting help with a lawsuit you can't afford to fight alone

Legal aid organizations in most states offer free or low-cost help with debt collection lawsuits for people under a certain income threshold, and some courts have self-help resources specifically for answering a debt collection summons without a lawyer. It's worth checking both before assuming you have no options once a suit is filed.

Debt buyers versus original creditors

Many collection accounts have been sold, sometimes more than once, to a debt buyer that purchased the account for a fraction of its face value. A debt buyer still has to prove it owns the debt and that the amount is accurate if you dispute it, and older accounts that have changed hands several times are exactly where documentation gaps and errors are most likely to surface.

Key takeaway Federal law limits when, how, and how often a debt collector can contact you, and gives you a real right to dispute or validate a debt before paying anything. Knowing the rules doesn't erase the debt, but it does put you back in control of the conversation.

If the debt itself is real and manageable, it's worth comparing your full range of options next, starting with whether free credit counseling could help before anything else.
