# Addresses

The type `Address` represents an address. Addresses are unsigned integers with a size of 64 bits (8 bytes). Hexadecimal integer literals can be used to create address values.

```
// Declare a constant that has type `Address`.
//
let someAddress: Address = 0x436164656E636521

// Invalid: Initial value is not compatible with type `Address`,
// it is not a number.
//
let notAnAddress: Address = ""

// Invalid: Initial value is not compatible with type `Address`.
// The integer literal is valid, however, it is larger than 64 bits.
//
let alsoNotAnAddress: Address = 0x436164656E63652146757265766572
```

Integer literals are not inferred to be an address.

```
// Declare a number. Even though it happens to be a valid address,
// it is not inferred as it.
//
let aNumber = 0x436164656E636521

// `aNumber` has type `Int`
```
