The process of blocking a number on your home phone landline is actually quite simple. All you need to do is contact your service provider and request that they block the number for you. In most cases, service providers will be able to block the number for you at no additional cost.
Once the number has been blocked, any calls from that number will automatically be redirected to a busy signal. Additionally, the caller ID on blocked numbers will typically show up as blocked or private. If you have any further questions about blocking numbers on your home phone landline, we encourage you to contact your service provider directly.
