# Identity and fraud

New in Daraja 3.0. Cheap checks worth running before you send money to a number you have not paid before.

## check_sim_swap

`control`

Return the date a number was last SIM-swapped. A recent swap is a strong fraud signal; check this before disbursing to an unfamiliar number.

| `phoneNumber` **required** | `string` | Number to check. |

## check_age_on_network
