The short version

Quick answer

To reduce unwanted contact, consider registering a personal number with the National Do Not Call Registry, making a clear request to a recognized marketing sender and using your phone or carrier’s spam controls. Registration is not a technical block; unlawful senders remain subject to applicable law even if they ignore it. Keep needed evidence before changing or deleting messages.

Registry registration and blocking are different

The FTC describes the Registry as a list for telemarketers, not a call-blocking service. Registration is free. Its guidance says sales calls can take up to 31 days to stop, and a registration remains unless cancelled or removed, including disconnection and reassignment.

That practical guidance is not blanket permission to make any call during a 31-day period. The FCC regulation’s list-access requirement is one condition in an error-based safe harbor with other conditions. Registration also does not establish that every later communication is prohibited.

What about marketing texts?

Section 64.1200(e) applies the FCC’s specified do-not-call and telemarketing rules to wireless calls and text messages within the scope it describes. Message purpose, permission, residential use where relevant and exceptions still matter.

Regulatory coverage does not by itself answer whether a particular person can recover in court. The TCPA has separate private-action provisions; do not turn Registry registration into an automatic entitlement to money. Use the court-decision map for the distinct texts-as-calls litigation issue.

An existing relationship is not unlimited permission

For telephone-solicitation purposes, the FCC’s established-business-relationship definition includes a qualifying transaction within eighteen months or inquiry/application within three months, subject to its conditions. A seller-specific do-not-call request terminates that relationship for telemarketing purposes even if business continues.

This is not the written-consent test for every regulated automated or prerecorded marketing communication. Preserve any forms and distinguish a service update from a promotion instead of assuming a purchase authorizes all future messages.

Make a specific request and preserve it

For covered company-specific do-not-call requests, §64.1200(d) requires recording when made, honoring within a reasonable time no longer than ten business days, and honoring the request for five years. The rule addresses which entity and affiliates it reaches; one request is not necessarily a universal opt-out from unrelated companies.

Use the STOP guide for consent revocation and its narrow waiver issue. Record the exact request, who received it, the confirmation and subsequent contact. These notes help organize the facts; they do not establish that a deadline violation occurred.

Add filtering without assuming legal opt-out

The FTC identifies phone, wireless-provider and app tools for filtering or blocking unwanted texts. Available controls vary; inspect the current instructions and any data-sharing explanation.

For a suspicious message seeking personal or financial information, avoid its links and verify independently. Filtering, blocking, reporting and telling a sender to stop are different actions. Choose the action for your problem without assuming a device setting sent a request to the company.
