Mobile or landline: why it matters for SMS
SMS is delivered to mobiles. Messages to landlines are usually not delivered, so checking numbers before you send keeps your list clean and your costs down.
How the check works
Every country publishes a numbering plan that says which number ranges are mobiles, landlines, toll-free numbers and so on. The checker matches your number against that plan, using numbering data from Google's open-source libphonenumber project.
Countries where you cannot tell
Some countries, including the United States and Canada, give mobiles and landlines numbers from the same ranges. For those numbers the checker shows "landline or mobile", because the number alone cannot say which.
Questions about checking phone numbers
Can it tell if a number is a mobile?
For most countries, yes: it checks the number against the country's numbering plan. Some countries, including the United States and Canada, use the same ranges for mobiles and landlines, so the checker says it cannot tell.
Does it check that the number is switched on?
No. It checks the number is valid for its country. It cannot tell if the number is active, which network it is on, or whether it has moved to another network.
Can a landline receive SMS?
Usually not. Messages to landlines are normally not delivered, so remove them from SMS lists.
Is the number sent anywhere?
No. The check runs in your browser.
