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

By Paul Katz

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.

Step 1

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 2

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 3

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 4

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.

Tips & Warnings

  • If you are being harassed or threatened by a persistent caller, you may want to consult local law enforcement about potential legal remedies. Many states have laws against using cell phone technologies for cyber-stalking and cyber-harassment, and even those that do not can likely offer protection under conventional harassment laws.
