What isnumber portability

Number portability is the process of transferring your phone number when switching to a new service provider or carrier. This means you can keep your existing phone number even if you change your service provider. Initially introduced by 800 numbers, local number portability (LNP) and eventually wireless number portability (WLNP) were established.

On November 24, 2003, customers in the top 100 metropolitan service areas (MSAs) in the United States were able to transfer their phone numbers to a new carrier, which was celebrated as “Cellphone Independence” day. Now, landline numbers can also be transferred to a cellular carrier.

How does number portability work?

When you decide to switch your phone service provider, the new carrier will request your phone number from your old carrier. After verifying that the request is legitimate, your old carrier will then release your phone number to the new carrier. It typically takes a few days for the transfer to be completed, but you’ll be able to keep using your old phone number during this time.

Why is number portability important?

Number portability offers several advantages to consumers. You can keep your phone number even if you switch to a new carrier, so you don’t have to go through the hassle of informing your contacts about your new number. It also promotes competition among service providers, as customers are less hesitant to switch to a new provider if they can keep their existing phone number.


Can I transfer my phone number to a different type of service, like a VoIP provider?

Yes, number portability applies to all types of service providers. You can transfer your phone number to a VoIP provider or any other type of service provider that uses phone numbers.

Can I keep my phone number even if I move to a different area code or city?

Yes, number portability allows you to keep your phone number even if you move to a different area code or city. However, you may have to pay additional fees depending on the carrier and the location.

Final thoughts

Number portability is a convenient feature that allows you to keep your phone number even if you switch to a new carrier or service provider. It is important to note that number portability is regulated by the government and follows a specific process. If you’re thinking about switching to a new carrier, make sure to check their number portability policies.
