How long before an old phone number is reassigned?
To reduce unwanted and intrusive calls intended for a phone number's previous owner, the Commission now requires service providers to regularly report permanent number disconnections and to wait a minimum of 45 days before reassigning a disconnected number to a new user.
Is it possible to use an old phone number?
If you're switching service providers and remaining in the same geographic area, you can keep your existing phone number. This process – often referred to as phone number porting – can be done between wireline, IP and wireless providers.
Can old numbers be reused?
What is phone number recycling? Phone number recycling is the industry term that refers to the event when that deactivated/disconnected number gets reassigned to someone else. Typically, it takes at least 90 days for this reassignment to take place but it can be faster in high-demand area codes (212, 310, etc.).
