How to Block Political Texts on iPhone

Stop the flood of political fundraising and campaign texts on your iPhone — three settings that cut 95% of them out.

1. Step 1. Reply STOP to known senders (your legal right)

   Federal law (Telephone Consumer Protection Act, or TCPA) requires political campaigns to honor opt-out requests when YOU initiate the relationship — for example, if you donated to a candidate or signed a petition. Reply with just the word "STOP" (no other words) to those texts. The campaign is legally required to remove you within 30 days. This will not stop campaigns you have never interacted with. They did not have to ask permission to text you in the first place. Replying STOP to a campaign you have NEVER engaged with may actually confirm your number is active and bring more texts.

   Warning

   Do NOT reply STOP to unknown or suspicious numbers — only to campaigns you have donated to or signed up with. Replying to a scam text confirms your number works and brings more spam.

2. Step 2. Turn on "Filter Unknown Senders" in Messages

   This is the single most effective setting. It splits your Messages app into two folders: people in your contacts, and unknown senders. Open Settings, scroll down and tap "Messages," then scroll down and turn on "Filter Unknown Senders." Now any text from a number not in your contacts goes to a separate "Unknown Senders" folder in the Messages app. Your main inbox only shows messages from people you know. You can still check the Unknown folder once a day for legitimate messages (a delivery notification, a one-time code). But you will not be notified for every spam text.

   Quick Tip

   Quick Tip: This setting also filters out delivery scam texts ("Your USPS package is on hold"), gift card scams, and most political solicitations.

3. Step 3. Block specific numbers as they come in

   For each political text from a number not in your contacts: open the message, tap the phone number at the top of the conversation, tap "Info," then scroll down and tap "Block this Caller." Confirm "Block Contact." You will never get another call or text from that exact number. Campaigns rotate through dozens of numbers. So you will need to block many — but each blocked number is one less interruption. There is no limit to how many numbers you can block on iPhone.

4. Step 4. Report political spam as Junk

   Below every text from an unknown sender, you will see a "Report Junk" link. Tap it and confirm. This does two things: it deletes the message. And it sends the sender's phone number to Apple and to your carrier (Verizon, AT&T, T-Mobile). Carriers use these reports to update their spam filters, which protects everyone. It does not stop the specific campaign from texting you, but over time, carrier-level filtering improves and you see fewer of them.

5. Step 5. Stop political emails too (since campaigns use both)

   Most campaigns text and email — and political emails are not subject to CAN-SPAM rules either. In Apple Mail or Gmail, scroll to the very bottom of any political email and look for an "Unsubscribe" link. Click it and confirm. Then in your email app, mark any remaining political emails as spam — over time, your spam filter learns. If you have ActBlue or WinRed contributions on file, log into those accounts and remove your phone number and email preferences from your profile. These two platforms power most U.S. political fundraising and your contact info gets shared widely across campaigns.

   Warning

   Unsubscribing from a campaign on ActBlue or WinRed only stops that specific campaign — not every campaign that has your contact info. You may need to unsubscribe from dozens.

6. Step 6. Register on the FTC Do Not Call list (limited help)

   Go to donotcall.gov and register your cell phone number. This is free. It does NOT block political texts — but it DOES block telemarketing calls and texts from for-profit companies. After 31 days, illegal telemarketers can be reported and fined. Political campaigns are still exempt, but cutting out commercial spam reduces your overall spam volume a lot.

7. Step 7. Use a spam-blocking app for extra coverage

   For an extra layer, install a free spam-blocking app like Hiya, Truecaller, or RoboKiller. These apps maintain a database of known spam senders (including known political spam numbers) and silence them automatically. On iPhone: open Settings, tap "Phone," tap "Call Blocking & Identification," and turn on the toggle for the app you installed. They work for both calls and texts. Most are free with optional paid tiers. Hiya is the lightest on your battery.

   Quick Tip

   Quick Tip: AT&T ActiveArmor, Verizon Call Filter, and T-Mobile Scam Shield are free carrier apps that do similar work — start with those before paying for a third-party app.
