How to Block a Particular Number From Being Received on Your Cell Phone

Unwanted cell phone calls can be a huge hassle, especially if you're receiving repeated calls from a few persistent callers. Fortunately, a number of cell phone providers are willing to block particular numbers for their customers, and many cell phones can be programmed to reject or silence calls from specific callers.

You can block unwanted incoming calls from particular numbers.

Step

Contact your cell phone service provider. Many providers have developed parental control packages that enable parents to block particular calls to their child's phone; these packages can also be used to block unwanted calls to your own cell phone. Some providers are also willing to block harassing calls upon request.

Step

Check your cell phone settings. Most cell phones do not enable you to block specific numbers, but many phones come with features that can lessen their disruption. Enable your phone's "Block Private Numbers" feature to disable calls from unlisted or caller-ID-blocked numbers. If your phone enables you to assign different rings to individual numbers, assign a silent ring to the number you want to block.

Step

Download call-screening software for your smartphone. Several software programs, such as MagiCall and CallShield Pro, can block individual numbers. Other programs require all incoming callers to enter a multi-digit code to get through to your phone; callers unable to provide the correct code are diverted.

Step

Sign up for the National Do Not Call Registry. Thirty-one days after you enter your number in the registry, telemarketers will not be permitted to contact your phone. If the unwanted calls you wish to block are commercial in nature, this will stop them.
