Capabilities

What you can do with Numbers Lookup

Number lookup checks a phone number before you use it: whether the format is valid and, in many cases, whether it is a mobile number and which network it belongs to.

Validate formats

Catch typos and invalid numbers early.

Know the line type

Distinguish mobile numbers from landlines where data is available.

Network information

See which operator a number belongs to, where available.

Cut wasted sends

Skip numbers that cannot receive your message.

Cleaner data means fewer failed messages and less wasted effort, and it helps you choose the right channel for each number.
