# Extracting codes from email and SMS

Learn how to test verification codes found in email and SMS messages with Mailosaur.

## Before you begin
The examples shown below are based on two key assumptions:

1. You have already created a basic automated test using our [getting started guides](/docs/automation).
2. You have a chosen assertion library that you will use to test the values shown below.

## Codes within email and SMS text content
When an email or SMS message is sent with plain text content, Mailosaur automatically extracts anything that looks like a verification code and makes these available via the `text.codes` array. Each code has a `value` property, representing the code itself.

```nodejs
// How many codes?
console.log(message.text.codes.length) // 2

const firstCode = message.text.codes[0]
console.log(firstCode.value) // "456812"
```

```python
# How many codes?
print(len(message.text.codes)) # 2

first_code = message.text.codes[0]
print(first_code.value) # "456812"
```

```java
// How many codes?
System.out.println(message.text().codes().size()); // 2

Code firstCode = message.text().codes().get(0);
System.out.println(firstCode.value()); // "456812"
```

```csharp
// How many codes?
Console.WriteLine(message.Text.Codes.Count); // 2

var firstCode = message.Text.Codes[0];
Console.WriteLine(firstCode.Value); // "456812"
```

```ruby
# How many codes?
puts(message.text.codes.length) # 2

first_code = message.text.codes[0]
puts(first_code.value) # "456812"
```

```php
// How many codes?
print(count($message->text->codes)); // 2

$firstCode = $message->text->codes[0];
print($firstCode->value); // "456812"
```

```go
// How many codes?
fmt.Println(len(message.Text.Codes)) // 2

firstCode := message.Text.Codes[0]
fmt.Println(firstCode.Value) // "456812"
```

## Codes within email HTML content
As with codes found within the text content of a message, Mailosaur also detects and extracts codes found within the HTML of any email.

These are made available via the `html.codes` array.

```nodejs
// How many codes?
console.log(message.html.codes.length) // 2

const firstCode = message.html.codes[0]
console.log(firstCode.value) // "456812"
```

```python
# How many codes?
print(len(message.html.codes)) # 2

first_code = message.html.codes[0]
print(first_code.value) # "456812"
```

```java
// How many codes?
System.out.println(message.html().codes().size()); // 2

Code firstCode = message.html().codes().get(0);
System.out.println(firstCode.value()); // "456812"
```

```csharp
// How many codes?
Console.WriteLine(message.Html.Codes.Count); // 2

var firstCode = message.Html.Codes[0];
Console.WriteLine(firstCode.Value); // "456812"
```

```ruby
# How many codes?
puts(message.html.codes.length) # 2

first_code = message.html.codes[0]
puts(first_code.value) # "456812"
```

```php
// How many codes?
print(count($message->html->codes)); // 2

$firstCode = $message->html->codes[0];
print($firstCode->value); // "456812"
```

```go
// How many codes?
fmt.Println(len(message.Html.Codes)) // 2

firstCode := message.Html.Codes[0]
fmt.Println(firstCode.Value) // "456812"
```

## What if my code is not detected?

Mailosaur automatically detects most common verification code patterns, however, you can still [write your own regular expressions](/docs/automation/text-content#5-finding-a-6-digit-code) to meet more specific requirements.
