How to block an unwanted phone number on any phone

There several reasons to block a phone number, telemarketers who just won’t stop calling you, ex partners that can’t let go or scammers that are trying to steal your money and your information. If you’re at the point where you can’t take it any longer, you always have the possibility to block that number. Here are the steps you have to take.

Do Not Call

The first step you can take in order to get rid of those pesky telemarketers is to register your number with the National Do Not Call Registry. On this website you can register up to three phone numbers at once. Apart from that, they also need an email address, given that you have to confirm your registration.

The FTC runs this registry and states that your number will be added within 24 hours. Once it is on this list, telemarketers have to remove your number from their lists within 31 days. If they keep calling you, you have the right to file a complaint.


If your phone is under AT&T it might be the easiest to follow the steps listed below, given that it is very specific on a device-by-device basis.

Verizon allows you to block up to five numbers per account, but only for the duration of 90 days. In order to do so, log into your account on their website, click on My Account > Manage Verizon Family Safeguards & Control > Call & Message Blocking Feature > Add Now. Here you can add up to five numbers. In order to have a permanent blocking of the numbers, you have to sign up for Verizon FamilyBase.

Log into your Sprint account, go to My Preferences > Limits and Permissions > Block Voice, select Block Voice only the Following Phone Numbers for Inbound and Outbound Calls, type in the number you want to block and click on Add Number and Save.

Operating Systems

In order to block a number on an iPhone, open the Phone app and select “Recent”. Find the number you want to block and click on the circle next to it. If you scroll down all the way in the next screen, you find the option “Block this Caller”.
If you want to block an already existing contact from your list without a recent call, go to your Settings > Phone > Call Blocking & Identification > Block Contact. Now you can chose the name from your contact list.
Please note: a number you have blocked, cannot be reached by you either.

For the versions called Marshmallow or Nougat, open Dialer, select your recent calls list and select Block/ Report for the number you want to block. For Lollipop select your phone app and go to Call Settings > Call Rejection > Auto reject List and add the number to that list.

If you want to block calls and messages on a Microsoft phone, go to Settings > Call+SMS Filter, accept the Terms of Use and turn Block Calls on. Now you can block number in your phone app by holding down the number and hitting Block Number.
