# Telephone Number

Values of this syntax hold telephone numbers, strings of printable characters, as in `PrintableString`, that comply with the internationally agreed format for representing international telephone numbers.

Examples: `+1 415 555 1212`, `+1-415-555-1212`.

The syntax corresponds to the following ASN.1 type from X.520:

```
PrintableString (SIZE(1..ub-telephone-number))
```

The integer value of `ub-telephone-number` depends on the implementation.
