## What is Number Shield?

Block annoying scammers who hide behind fake phone numbers.

Do you get unwanted calls or text messages from phone numbers similar to your own?  With Number Shield, block an entire group of numbers at once.  Just enter a wildcard for each digit you want to block.

For example, if your number is 714-555-1234, scammers might use a number like 714-555-6789.  Block all similar numbers by entering 714-555-####.  Wildcards and numbers can be combined in any order you choose.  Block international numbers, too!

To make sure you don't miss calls from your family and friends, phone numbers in your contacts are always allowed.

Block numbers directly from your phone's missed calls screen.  Just follow these steps:

1. Tap the “ i ” button next to the missed call.
2. Tap “Share Contact”.
3. Tap “Block Similar Numbers”.  (If you don't see this action, tap “Edit Actions...“ to enable it.)
4. Now you'll see the Number Shield number entry screen.  Tap “Done” to block calls from similar numbers.

Please note:

• Each number pattern can contain up to 7 wildcards, and up to 50,000,000 phone numbers can be blocked.
• Blocked calls are sent directly to voice mail.
• Blocked text messages are sent to the “Junk” filter in the Messages app.
• iMessage messages are not blocked.
• When “Do Not Disturb” is enabled on your phone, calls that should be blocked may appear in your phone's list of missed calls.

### 1/5 — Doesn’t work

*2026-08-06, version 3.3*

I paid the subscription and it still doesn’t work.  I get spam voicemails and in the recent calls section the number is there with it saying blocked by Number Shield.  It says it blocked the calls that left a voicemail!  Doesn’t make sense.  App removed…

### 1/5 — Does not work

*2026-08-05, version 3.3*

Loaded all the spam #’s as instructed. Says over a million numbers blocked.
Still get spam from blocked numbers.

### 5/5 — Not 2.99

*2026-07-30, version 3.3*

Charged me $8.55

### 1/5 — Doesnt work (in the UK)

*2026-07-18, version 3.3*

Sadly this doesnt seem to work at all - have blocked all 0843 numbers yet i continue to get called by them every couple if days

### 1/5 — Trash

*2026-07-16, version 3.3*

This app is charging for the same thing my phone does

### 5/5 — My single greatest App Store purchase.

*2026-07-09, version 3.3*

For years I’ve fought with AT&T and spam callers from one area code. This solved it. Just today it blocked over 30 spam calls.

### 1/5 — App doesn’t work, Customer Support won’t respond

*2026-06-24, version 3.3*

App keeps crashing, won’t load numbers. The FAQ page refuses to load. I contacted customer support, but they don’t reply back. Looks like I got ripped off, nothing else I can do except leave a 1-star review.

### 5/5 — Great app

*2026-06-22, version 3.3*

It works

### 5/5 — Amazing

*2026-06-17, version 3.3*

This app lets me do what Verizon refuses to: block specific area codes that i get 10+ spam calls a day from. Verizon wants me to pay an additionally monthly fee to block just 10 "neighborhood codes"(the first 6 digits).

Number shield just let me 6 area codes i get all my spam from. Number shied let me block 6+ million numbers for a one time payment of 2.99! Verizon wanted me to pay 3.99 A MONTH to block just 10 neighborhood codes(6 digits) thus only 100,000 numbers. Number shield is doing what verizon refuses to. This service should be provided by verizon for FREE but i had to find a third party app to handle this. Thank you for this great, fairly one-time-prices app. 10/10 amazing

### 5/5 — WOW. Spam has dropped a lot

*2026-06-10, version 3.3*

So this may sound bad, but I have only had 23 spam calls for the first 20 days of May, but that is down from over 60 a month. I usually get 2-3 a day from similar exchanges. Now I block them and my spam calls are a third of what they used to be. 

International spam has completely stopped. Great program. 

UPDATE: I have been using this app for years. I don’t get nearly as many spam calls as I used to. However, my spam text messages have skyrocketed. When there is a pattern, I have started blocking the exchanges for spam texts and those are dropping. The only problem is that spammers are constantly changing numbers. 

I’m still happy with the results.
