Phone number cleaner

The cleaner recognizes common separators, applies a default country code, converts to E.164, and reports valid, invalid, and duplicate entries.

Steps

  1. 1

    Open the default country or region picker; search by country name, ISO code, or calling code.

  2. 2

    Choose the default country or region for numbers without a country code.

  3. 3

    Paste one phone number per line.

  4. 4

    Run Clean and review valid, invalid, and duplicate counts.

  5. 5

    Copy or download valid results and use them as task input.

Limits and cautions

  • You must still verify country assignment; a wrong default can produce well-formed numbers for the wrong country.
