Three sections carry the prohibitions, and each is built the same way: a general standard, then examples that expressly do not limit it.
Section 1692d, harassment or abuse. A collector "may not engage in any conduct the natural consequence of which is to harass, oppress, or abuse any person in connection with the collection of a debt." The listed violations include threats of violence or criminal means, obscene or profane language, publishing a list of consumers who allegedly refuse to pay, advertising a debt for sale to coerce payment, causing a telephone to ring repeatedly with intent to annoy, and placing calls without meaningful disclosure of the caller's identity.
Section 1692e, false or misleading representations. Sixteen paragraphs follow the general ban, and several are the everyday substance of collection disputes: falsely implying government affiliation, misrepresenting "the character, amount, or legal status of any debt," implying that a communication is from an attorney when it is not, threatening arrest or seizure "unless such action is lawful and the debt collector or creditor intends to take such action," threatening any action that cannot legally be taken or is not intended, communicating credit information known to be false "including the failure to communicate that a disputed debt is disputed," sending documents that simulate court process, and using any business name other than the collector's true name. Paragraph (11) is the source of the familiar disclosure: the initial communication must state that the collector is attempting to collect a debt and that any information obtained will be used for that purpose, and subsequent communications must disclose that they come from a debt collector.
Section 1692f, unfair practices. Again a general standard, then specifics. The first is the broadest: no collection of any amount, "including any interest, fee, charge, or expense incidental to the principal obligation," unless expressly authorized by the agreement creating the debt or permitted by law. Others govern postdated checks, charges caused by concealing the purpose of a communication, taking or threatening nonjudicial action to dispossess property where there is no present right to it or the property is exempt, communicating by postcard, and putting any language or symbol on an envelope that reveals the collection business.
The venue rule is one of the Act's most directly usable provisions. Under 15 USC 1692i a collector bringing a legal action on a debt must file, for an action to enforce an interest in real property, only in the district where the property is located, and otherwise only in the district "in which such consumer signed the contract sued upon; or in which such consumer resides at the commencement of the action." That is the answer to being sued hundreds of miles away in a county chosen for the collector's convenience. Subsection (b) adds that nothing in the Act should be read as authorizing collectors to sue in the first place.
Regulation F supplies the numbers, and the call-frequency rule is more subtle than its reputation. Under 12 CFR 1006.14(b)(2)(i) a collector is presumed to comply if it places calls about a particular debt neither more than seven times within seven consecutive days, nor within seven consecutive days after having had a telephone conversation with the person about that debt, with the day of the conversation counting as the first day. Under (b)(2)(ii) a collector that exceeds either frequency is presumed to violate the rule. Both are presumptions, and both are rebuttable, so neither figure is a hard cap in either direction. Paragraph (b)(3) excludes three classes of call from the count: calls placed with the person's prior consent given directly to the collector within the preceding seven days, calls not connected to the dialed number, and calls to the narrow list of people at 1006.6(d)(1)(ii) through (vi).
Paragraph (b)(4) then defines the unit being counted, which is what decides how many calls the presumption actually covers: "particular debt means each of a consumer's debts in collection." It is per debt, not per person. The paragraph adds one exception, which appears in very little consumer material: "in the case of student loan debts, the term particular debt means all student loan debts that a consumer owes or allegedly owes that were serviced under a single account number at the time the debts were obtained by a debt collector."
The limited-content message explains the voicemail that says almost nothing. Section 1006.2(j) defines a limited-content message as a voicemail for a consumer containing all of four required items, optionally some of four more, "and that includes no other content." The required four are a business name for the collector that does not indicate it is in the debt collection business, a request that the consumer reply, the name or names of one or more natural persons the consumer can contact, and a reply telephone number. The optional four are a salutation, the date and time, suggested times to reply, and a statement that a reply may be answered by any of the company's representatives. A message built that way is not a communication about a debt, so leaving it does not risk disclosing the debt to whoever else hears the voicemail, and the Bureau's commentary confirms it does not violate the requirement to disclose the caller's identity meaningfully.
Two rules in 1006.30 answer questions that otherwise look like mistakes. Under (a)(1) a collector must not furnish information about a debt to a consumer reporting agency before it has either spoken to the consumer about the debt or sent a letter or electronic message and waited a reasonable period for a notice that it was undeliverable. That is why a collection should not appear on a credit report before anyone has made contact. Under (b)(1) a collector must not sell, transfer for consideration, or place for collection a debt it knows or should know has been paid, settled, or discharged in bankruptcy, subject to narrow exceptions such as returning it to the owner.
One current point about enforcement posture, kept separate from the law. On May 12, 2025 the Bureau withdrew a large number of guidance documents at 90 FR 20084, including advisory opinions and bulletins that had addressed time-barred debt, medical debt collection and pay-to-pay fees, and stated that it does not intend to prioritize enforcement of the withdrawn guidance. The document says the withdrawal "is not necessarily final." What did not change is the statute or Regulation F, neither of which was amended. So the rules described on this page are in force, and the withdrawal is a fact about agency priorities rather than about the law.
