Short answer - Cloaked numbers are virtual numbers, and some sites don't like that. We are almost finished developing our solution for this, which will utilize eSIM technology to give you a number that will be accepted on all websites.

Long answer:

How Cloaked Numbers Work

Cloaked-generated numbers are classified as real, cellular numbers, but they are based on Voice Over Internet Protocol technology that distinguishes them from traditional cellular numbers. If a site rejects a Cloaked-generated number, this is not an error or fault with your Cloaked account and is a limitation put in place by some sites and services that reject VoIP-based phone numbers from being used.

Websites and services may run checks to see if the number in question has a recognized NPA-NXX block (also referred to as the North American Numbering Plan) that can be matched to an original operating company (AT&T, Verizon, etc) along with checking the Number Portability Administration Center database (NPAC) for information on the service provider.

Services may also check to see what physical location is associated with the VoIP number being used, as well as the location of your IP address and other details of your web traffic to make decisions about what they will and will not permit you to do. Many services and websites will also have their internal systems and databases which they maintain which can increase complexity in utilizing certain phone numbers to generate accounts.

What Cloaked Can Do

If a user or Cloaked discovers a service or site that does not support the numbers we generate, we have recently updated Cloaked to be able to offer an eSIM solution (in closed beta) that will allow you to have a carrier-based Cloaked number that you can use for these services.

What You Can Do

If you come across a service or website that is not accepting your Cloaked generated phone numbers we are here to help. You can raise a ticket with Cloaked Support who can let the development teams know that you have encountered a website that doesn't work with Cloaked so we can not only assist you but advise our other users as well.
