However, there are some cases where multiple phone numbers may be associated with the same device or line, such as with dual-SIM phones or call forwarding services. In this answer, I will explore the concept of uniqueness in phone numbers in more detail. Firstly, it’s important to understand that phone numbers are assigned by telecommunications companies and are unique within their network. This means that two different companies can have the same phone number, but that number will be unique within each company’s network.
