Where iPhone stores spam texts and how to see them

iPhone automatically sorts suspected spam texts into a separate folder within the Messages app, but you have to know where to look. Open Messages, then tap "Filters" at the top left of your conversation list. You will see two options: "All Mail" and "VIP". Scroll down past those and you will find "Unknown Senders" — this is where iPhone puts texts from numbers not in your contacts.

The "Unknown Senders" folder is not the same as spam. It holds any message from someone you have never texted before. Some of these will be legitimate — delivery notifications, appointment reminders, password reset codes. Others will be scams or marketing. iPhone does not have a dedicated spam folder the way email does; instead, it relies on you to check Unknown Senders and decide what to do with each message.

If you have iOS 17 or later, you also have access to a "Blocked" folder. This holds messages from numbers you have manually blocked or that your carrier has blocked for you. To see it, go to Settings > Messages > Blocked Contacts. The list shows phone numbers, not the actual messages — those are deleted.

Key Takeaways

  • Suspected spam texts appear in the "Unknown Senders" folder in Messages, not in a separate spam folder like email has.
  • You can block a sender directly from a message by swiping left on it and tapping "Block", which moves future messages to your Blocked folder.
  • Reporting a message as spam to your carrier (by tapping "Report Junk" on iOS 17+) helps block similar messages for other users, but does not undo a scam that already happened.
  • Do not reply to suspected spam or click links in unknown messages, even to unsubscribe or confirm you received it.
  • Your carrier may offer a spam-filtering service you can turn on in Settings > Messages to catch more suspected spam before it reaches you.

How to block a sender and report spam

When you receive a text from an unknown number, swipe left on the message in your conversation list. You will see two options: a trash icon and an info icon. Tap the info icon (the circle with an "i" in it) to open the message details. From there, tap "Block this Caller" at the bottom of the screen.

Blocking prevents that number from texting you again — their messages will not appear in your inbox or Unknown Senders. If you want to report the message as spam to your carrier, tap "Report Junk" instead (this option appears on iOS 17 and later). Reporting does two things: it blocks the number and sends information about the message to your carrier so they can identify patterns and block similar messages for other customers. Reporting does not recover money or undo a scam; it only helps prevent future spam from that source.

If you have already deleted a message and want to block the sender, open Settings > Messages > Blocked Contacts and tap "Add New". Type or paste the phone number you want to block. You can also ask Siri: say "Block this number" and give the phone number, and Siri will add it to your blocked list.

Carrier-level spam filtering and what it catches

Your phone carrier — AT&T, Verizon, T-Mobile, or another provider — can filter spam before it reaches your phone. This filtering is separate from iPhone's Unknown Senders folder. To turn it on, go to Settings > Messages and look for an option related to your carrier's spam filter. The exact name varies: AT&T calls it "AT&T Call Protect", Verizon offers "Call Filter", T-Mobile has "Scam Shield".

These services use databases of known spam numbers and patterns to block or flag incoming texts. They catch many common scams — fake bank alerts, prize notifications, phishing links — but they are not perfect. Some legitimate messages may be blocked by mistake, and new scams may slip through. If you turn on carrier filtering and stop receiving texts you expect, check your carrier's app or website to see if messages were blocked.

Carrier filtering is usually free, though some carriers offer a paid premium version with more aggressive blocking. The free version is sufficient for most people. If you turn it on and find it blocks too many legitimate messages, you can turn it off in the same Settings menu.

What to do if you already responded to a scam text

If you clicked a link in a suspected scam message or replied with personal information, act quickly. First, block the sender when ready using the steps above. Then, depending on what information you shared, take these steps: if you gave a password or PIN, change it right away on the official website or app for that service. If you shared your Social Security number, credit card number, or banking details, contact your bank and the three credit bureaus (Equifax, Experian, TransUnion) to report the incident and ask about fraud monitoring.

If you clicked a link and installed something, or if you are unsure what happened, restart your iPhone in Safe Mode to prevent any malicious software from running, then take your phone to an Apple Store or a trusted repair shop for a security check. Do not ignore the message or assume nothing happened — scammers often test whether a number is active before launching a full attack.

Report the scam to the Federal Trade Commission at reportfraud.ftc.gov. This does not reverse the scam, but it creates a record that helps law enforcement identify patterns and shut down scam operations.

Distinguishing real messages from scams in Unknown Senders

Not every message in Unknown Senders is spam. Delivery services, banks, and appointment reminders often text from numbers you have never contacted. Before you block or report a message, check whether it looks legitimate. Real messages from companies usually include a company name, a specific reference to your account or order, and a way to verify the message on the company's official website or app.

Scam messages typically ask you to click a link, confirm a password, or reply with personal information. They often use urgent language ("Your account has been locked", "Confirm your payment now") or offer something too good to be true ("You have won a prize"). They may misspell the company name or use a generic greeting like "Dear Customer" instead of your name. If you are unsure, do not click the link or reply. Instead, go directly to the company's official website or app and log in to check your account.

One reliable test: if a message claims to be from your bank or a payment service, call the customer service number on your bank card or the company's official website. Do not use a phone number from the text message. Ask whether they sent you that message. A real company will confirm or deny it when ready.

Setting up Do Not Disturb and custom notification rules

If you receive many texts from unknown numbers and want to reduce interruptions, you can silence notifications from Unknown Senders while still seeing the messages later. Go to Settings > Notifications > Messages. Scroll down to "Senders" and tap "Unknown". Turn off "Allow Notifications" so texts from unknown numbers will not make a sound or show a banner, but they will still arrive in your Unknown Senders folder for you to review when you have time.

You can also use Focus modes to control which messages interrupt you. Go to Settings > Focus and create a new Focus (for example, "Work" or "Sleep"). Add Messages to the Focus and choose which contacts can reach you. When that Focus is active, only messages from your chosen contacts will trigger notifications; everything else goes to Unknown Senders silently.

This approach lets you stay in control without missing important messages from people you know, while keeping spam and unknown senders from constantly interrupting you.

Frequently Asked Questions

Can I see messages I have already deleted from Unknown Senders?

No. Once you delete a message, it is gone. If you think you deleted a scam message and want to report it, you can still block the number by going to Settings > Messages > Blocked Contacts and adding it manually. Your carrier may have a record of the message even if your phone does not.

Why do legitimate companies text me from numbers not in my contacts?

Many companies use third-party services to send notifications. Your bank might use one vendor for alerts and another for password resets, so you receive texts from different numbers. This is normal and not a sign of a scam. If you trust the company, you can add the number to your contacts so future messages from that sender appear in your regular inbox instead of Unknown Senders.

Does reporting spam to my carrier stop the scammer from texting me again?

Reporting spam blocks that specific number from reaching you, so you will not see messages from it again. However, scammers often use different numbers for each campaign, so you may receive similar messages from other numbers. Blocking and reporting each one helps, but there is no single action that stops all spam.

What if my carrier's spam filter is blocking messages I actually need?

Turn off the carrier filter in Settings > Messages and check whether the messages arrive. If they do, the filter was blocking them by mistake. You can turn the filter back on and add the sender's number to your contacts so future messages bypass the filter. If you need messages from a specific company regularly, contact them and ask whether they can send from a different number or service that your filter does not block.

Is it safe to reply "STOP" to unsubscribe from spam texts?

No. Replying to a spam message confirms that your number is active and monitored, which makes you a more valuable target for future scams. Do not reply, do not click links, and do not call numbers in the message. Block the sender instead.
