# Cpf
- `Cpf()`
Validates a Brazillian CPF number.
```php
v::cpf()->assert('95574461102');
// Validation passes successfully
```
It ignores any non-digit char:
```php
v::cpf()->assert('693.319.118-40');
// Validation passes successfully
```
If you need to validate digits only, add `->digit()` to
the chain:
```php
v::digit()->cpf()->assert('11598647644');
// Validation passes successfully
```
