Phone Number Cleaner

Paste a messy list from Excel, WhatsApp or a form. Get back clean numbers in international format, with duplicates removed and bad numbers flagged.

Separate numbers with a new line, comma, semicolon or tab. Spaces and dashes inside a number are fine. Your numbers stay in your browser and are never uploaded.

What it fixes

  • Numbers starting with 0, 256, +256 or 00256 all become one format.
  • Spaces, dashes, brackets and dots are stripped out.
  • Duplicates are removed so you never pay to message someone twice.
  • Numbers with the wrong number of digits are listed so you can fix them.
  • Excel numbers shown like 7.72E+08 are flagged, because the digits were already lost.

Good to know

The network split for Uganda (MTN, Airtel and others) is read from the number's starting digits, so it is a close estimate, not a live check. It does not confirm that a number is active. Always keep your own copy of the original list.
