How many numbers can you port at a time?
In the Bandwidth dashboard, you can port up to 20,000 phone numbers from multiple service providers at one time with a sub-limit of 5,000 phone numbers per losing service provider through our “check portability” page.
In the Global dashboard, if you are porting numbers via the Global portal, each request can contain a maximum of 500 numbers. Requests have to be split per country and number type and area code. This is to reflect how requests are submitted to local service providers in each country.
