Configure Cleaning Options
Keep only first occurrence. Detects +971..., 00971... and 0971... as the same number.
Remove numbers failing E.164 format — unknown country code or wrong digit count.
Convert 0044..., (44)..., +44-7700 all to +447700... international format.
Remove numbers outside ITU-T range of 7–15 digits total.
Filter out detected landline numbers (heuristic, based on prefix analysis).

What This Tool Cleans & Fixes Automatically
Duplicate Removal
Detects duplicates across all formats. +971..., 00971... and 0971... are treated as identical before deduplication.
Format Normalisation
Converts every format — 00971..., (44)..., +44-7700-900000, 971 58 552 7099 — to clean E.164: +447700900000.
Country Code Prepend
Auto-prepends your selected country code to numbers missing + prefix. 0585527099 becomes +971585527099.
Invalid Format Removal
Removes numbers with unknown country codes, too few or too many digits, and non-numeric characters.
Country Filtering
Select specific countries from 22 options. Numbers from other countries are removed and flagged separately.

Identifies Mobile, Landline and Toll-Free numbers based on national prefix analysis for 15+ countries.
Test Number Detection
