# `disposable_phone_with_disposable_email`: a disposable number with a disposable address

Both contact details are on disposable lists: the number is a known temporary or receive-only service, and the email is at a burner provider.

- Appears in: `flag`
- Billing: Free. The consistency analysis is arithmetic over answers already paid for and never costs a credit of its own.

Each half is published by its own product as `is_disposable` and `disposable`. Both being true is the flag.

`is_disposable` on the phone answer is null while no disposable-number dataset is installed, and a null side is never read as a no.

**What to do.** The strongest of the pairings for signup vetting, because neither contact detail can receive anything for long.
