Test phone numbers

Number types

Standard numbers

Standard numbers are available for the following countries and are provisioned immediately:

• United Kingdom (UK)
• United States (US)
• Canada

Pricing for standard numbers is available on the Mailosaur pricing page.

Premium numbers

Premium numbers are available for countries outside the UK, US, and Canada. To set up a premium number, contact the Mailosaur support team, who will guide you through the process. Some countries have additional regulatory requirements (such as address verification), which will be discussed during setup.

Messaging support

Mailosaur supports any type of SMS message, including plain text messages and OTP codes. Some numbers also support MMS — contact the support team if you are unsure whether your number supports MMS.

Replying to SMS

You can reply to SMS messages from within Mailosaur. If you are replying using a US number, that number must be set up for 10DLC (10-Digit Long Code) compliance. The Mailosaur support team can set up 10DLC for you.

Sending SMS

Outbound SMS sending is available to certain Enterprise customers only. Contact the sales team to learn more.
