>_ HOW IT WORKS

STEP 01

Paste a number

International (+41 79 962 41 92) or local — pick the country if local.

STEP 02

Read the verdict

Valid, region, line type (mobile / landline / VOIP), formatted E.164.

STEP 03

Use the canonical form

Copy the E.164 — it's the format your ATS or CRM should store. Local formats break when re-importing across countries.

tipV2 will add a WhatsApp signal check (does the number have a WhatsApp profile picture?) — defer that lookup until you've narrowed down to your shortlist.
