Key Facts
- Federal level: A robocall uses an artificial or prerecorded voice; whether it is lawful depends on the number called, the call’s purpose, consent, and any applicable exception.
- Federal level: Most prerecorded sales calls require the recipient’s prior signed, written agreement, and that consent cannot be required as a condition of buying.
- Federal level: Registering a home or mobile number on the National Do Not Call Registry limits covered sales calls, but it does not physically block calls or cover every category of call.
- Federal level: Caller ID can be spoofed, so a familiar local number does not establish that a call is genuine.
A robocall is a phone call that delivers an artificial or prerecorded voice message. Some robocalls are permitted—such as a pharmacy refill notice or a school closing alert—while many unsolicited sales robocalls are prohibited. The federal answer depends on context, not simply on whether software placed the call.
Two federal rulebooks commonly apply
The Telephone Consumer Protection Act (TCPA) and FCC regulations restrict calls using certain automated dialing technology or artificial or prerecorded voices. The FTC’s Telemarketing Sales Rule separately governs many interstate telemarketing campaigns. A single sales campaign may have duties under both regimes.
The TCPA generally prohibits artificial- or prerecorded-voice calls to a residential line without prior express consent unless an emergency or regulatory exception applies. It also generally restricts calls using an automatic telephone dialing system or artificial or prerecorded voice to a wireless number without prior express consent, subject to statutory and regulatory details.

Sales robocalls face the strictest consent rule
Under the FCC rule, a call that introduces an advertisement or constitutes telemarketing and uses an artificial or prerecorded voice generally requires prior express written consent. The agreement must authorize the specified seller to deliver such calls to the designated number and must disclose that signing is not a condition of purchasing goods or services.
The FTC similarly says that a robocall selling something is illegal unless the seller has the consumer’s written permission. An established business relationship by itself does not supply permission for a prerecorded sales call under the FTC rule.
Consent is not permanent in every circumstance. FCC regulations require callers to honor reasonable revocation requests and prescribe rules for opt-out methods. Because consent rules have changed over time and can turn on the wording and channel of a request, current FCC materials should be checked before relying on a technical assumption.
Not every recorded message is a prohibited sales call
Purely informational calls do not become telemarketing merely because they use a recording. Examples may include appointment reminders, flight updates, school notices, and fraud alerts. But adding a sales pitch can change the analysis.
Federal rules also recognize exceptions and special categories, including emergency-purpose calls and certain calls involving tax-exempt nonprofit organizations. Political calls, charitable calls, debt-collection calls, surveys, and purely informational calls may fall outside FTC Do Not Call coverage, but another law or FCC restriction may still apply. “Exempt from the Registry” does not mean “free of every calling rule.”
The Do Not Call Registry is useful but limited
Consumers can register a home or mobile number free at DoNotCall.gov or by calling 1-888-382-1222 from the number being registered. Online registration requires completion through the emailed link. The FTC says a number should appear on the Registry the next day, although covered sales calls can take up to 31 days to stop.
A registration does not expire unless the number is disconnected and reassigned or the consumer asks for removal. The Registry tells law-abiding covered telemarketers not to call; it is not a call-blocking service and does not stop scammers who ignore the law.
Spoofed caller ID is a warning, not proof
Robocallers can manipulate caller ID so that a call appears local or seems to come from a trusted organization. Federal law prohibits knowingly transmitting misleading or inaccurate caller ID information with intent to defraud, cause harm, or wrongfully obtain anything of value, but spoofing can also have lawful uses.
Do not rely on the displayed number to authenticate a caller. If a call supposedly comes from a bank, agency, or company, end the call and contact the organization using a number from an official website, statement, or card.
What to do when an unwanted robocall arrives
- Hang up. Do not press a number to reach an operator or request removal from a suspicious recording; the FTC warns that responding may lead to more calls.
- Save useful details, including the displayed number, date, time, subject, company claimed, and any callback number. Do not call a suspicious number back merely to investigate.
- Use call-blocking or call-labeling features offered by the phone, carrier, or a reputable service. Blocking reduces disruption but does not determine whether a call violated the law.
- Report unwanted calls to the FTC at DoNotCall.gov and to the FCC through its Consumer Complaints Center. An FCC unwanted-call complaint supplies enforcement information; the FCC says it does not resolve each unwanted-call complaint individually.

State rules may add protections
This article describes the federal baseline. State telemarketing, privacy, recording, and consumer-protection laws may add consent requirements, restricted calling hours, state registration rules, or remedies. The caller’s location and the recipient’s location can both matter, so a federal exception should not be treated as automatic permission under state law.
