Getting bombarded with spam calls and texts? That persistent telemarketer who calls during dinner? That annoying ex who won't take a hint? Yeah, I've been there too. Last month I had a loan company call me nine times a day until I figured out how to shut them down for good. Blocking numbers on iPhone is easier than you think, but there are some quirks you should know about.
Why Blocking Phone Numbers Matters More Than Ever
Did you know Americans received over 55 billion robocalls last year? It's insane. I remember when blocking a number on iPhone felt like a nuclear option, but now it's basic self-defense. Beyond stopping scams, blocking helps with:
- Harassment from specific individuals (I had a stalker situation in college - blocking was crucial)
- Political campaign texts during election seasons
- Ex-partners who can't move on (been there!)
- Aggressive salespeople ignoring "do not call" requests
Apple's blocking tools have improved, but they're not perfect. Sometimes you'll still get those "Potential Spam" calls slipping through, which drives me nuts. Let's break down exactly how to block numbers using Apple's built-in tools.
Step-by-Step: Blocking Phone Numbers on iPhone
There are actually four different ways to block a number on iPhone, depending on how the contact reached you. I'll show you each method with real examples from my own phone.
This is how I blocked that loan company:
- Open your Phone app and tap "Recents"
- Find the number (tap the info icon ⓘ next to it)
- Scroll down, select "Block this Caller"
- Confirm with "Block Contact"
Takes about 8 seconds once you know where to look. I wish Apple made the block button more visible though – it's annoyingly hidden at the bottom.
Better for people you actually know:
- Open Contacts app
- Select the troublemaker's name
- Tap "Block this Caller" at the bottom
- Confirm your choice
Pro tip: If they're not in your contacts? Add them first with just their number – it's faster than you think.
For SMS and iMessage spam:
- Open the Messages app
- Open the conversation with the number
- Tap the contact name/photo at the top
- Select "info" (ⓘ icon)
- Choose "Block this Caller"
This works wonders for those "Your Amazon account is locked" scams. I get at least three weekly.
| Blocking Method | Best For | Time Required | Limitations |
|---|---|---|---|
| Recent Calls | Unknown numbers, telemarketers | 10-15 seconds | Only works for recent calls |
| Contacts List | Known contacts, ex-partners | 20 seconds | Must have contact saved |
| Messages App | SMS spammers, harassing texts | 15-20 seconds | Only blocks numbers that texted you |
| Voicemail Method | Numbers that leave voicemails | 30 seconds | Least efficient method |
Important note: Blocking a number on iPhone works across all Apple services. When you block them in Phone, they're automatically blocked in Messages and FaceTime. That consistency is one thing Apple actually got right.
What actually happens when you block a number? Contrary to popular belief:
- Callers hear one ring then go straight to voicemail
- Texts appear visually in your messages but you get no notifications
- They can't see you blocked them (no notification sent)
Advanced Blocking Techniques
The basic blocking tools are good, but what about those persistent spammers who keep changing numbers? Here's the advanced tactics:
Silence Unknown Callers
Found in Settings > Phone > Silence Unknown Callers. This sends all calls not in your contacts straight to voicemail. It's nuclear option but saved my sanity during tax season when scammers go wild. Just beware – it might block job interviews or doctor's offices.
Blocking International Scammers
To block the "+44" and "+1" spam calls:
- Create a contact named "BLOCK INTERNATIONAL"
- Add ALL international country codes you don't need (Google them)
- Block this contact
Crude but effective. I blocked 50+ countries this way.
Third-Party Blocking Apps Compared
When Apple's tools aren't enough, try these:
| App Name | Cost | Best Feature | Downsides |
|---|---|---|---|
| RoboKiller | $4/month | Answer bots that waste scammers' time | Expensive long-term |
| Hiya | Free/$3/month | Real-time spam database | Free version limited |
| Truecaller | Free/$5/month | Identify unknown numbers | Privacy concerns |
I've tested all three – RoboKiller's answer bots are hilarious but Hiya integrates smoother with iOS in my experience.
Managing Your Blocked List
To see who you've blocked:
- Go to Settings > Phone
- Tap "Blocked Contacts"
- Scroll through your block list
Unblocking someone is simple:
- In "Blocked Contacts", swipe left on the number
- Tap "Unblock"
Last year I accidentally blocked my dentist's office – took me two months to realize why they weren't calling about my appointment. Moral? Check your block list quarterly.
Critical Limitations You Should Know
Apple's blocking has frustrating gaps:
- No wildcard blocking - Can't block entire area codes (why Apple?!)
- Unknown callers slip through unless you enable "Silence Unknown Callers"
- Blocked texts still appear in your Messages app
- No scheduling (can't block only during nights/weekends)
The texts thing really bugs me. Blocking should mean complete invisibility, yet there they sit in your Messages like digital cockroaches. Apple needs to fix this.
Your Blocking Questions Answered
Can blocked callers leave voicemails?
Yes, but they go to a separate "Blocked Messages" folder at the bottom of your voicemail list. Check it monthly – sometimes legit callers get blocked accidentally.
Do blocked numbers know they're blocked?
No direct notification, but they might suspect because calls go straight to voicemail after one ring. Texts show as delivered but you never reply. Smart spammers know these signs.
Why am I still getting texts from blocked numbers?
Two possibilities:
1) They're texting from a different number (scammers have hundreds)
2) They're using iMessage instead of SMS (blocking works differently)
Can I block text messages without blocking calls?
Unfortunately no. When you block a number on iPhone, it blocks all communication channels – calls, texts, FaceTime. All-or-nothing approach.
Does blocking work for international numbers?
Yes, but you must enter the full international format (+country code). Just blocking "1234567" won't stop "+441234567" calls.
When Blocking Isn't Enough: Next Steps
If you're still getting harassed after blocking:
- Document everything - Screenshot calls/texts with timestamps
- Contact your carrier - AT&T/Verizon/T-Mobile offer advanced call protection
- File FCC complaint - For illegal robocalls (I did this last year - takes 5 minutes)
- Change your number - Nuclear option but sometimes necessary
My neighbor had a stalker situation – she documented 147 calls over three weeks. That evidence helped get a restraining order. Blocking was just step one.
Final Takeaways
Knowing how to block the number on iPhone is essential digital hygiene. The process takes seconds but saves hours of frustration. Remember:
- Apple's tools work well for individual numbers but struggle with mass spam
- Combine built-in blocking with Silence Unknown Callers for best results
- Check your block list quarterly for accidental blocks
- For serious harassment, go beyond blocking – document and report
Honestly, iPhone's blocking features feel half-baked compared to Android. Why can't we block by area code or schedule blocks? But until Apple improves things, these methods will keep most pests away. That loan company that called nine times daily? Haven't heard from them in six months. Bliss.
