Why You're LOSING Leading Zeros in Excel and How to KEEP Them

Описание: Trying to keep leading zeros in Excel for phone numbers or IDs — but Excel keeps removing them?

This often happens when you're adding a country code like 0045. Most users manually type it in or add an apostrophe, which turns the number into text and ruins calculations, validations, or exports. You might even run into the dreaded issue where your Excel 0 disappears from the front of numbers.

In this fast tutorial, you’ll learn:

❌ Why the manual/apostrophe method is risky

✅ How to use Custom Number Format to add prefixes without converting to text

Plus, you’ll see how Excel uses # and 0 in number formatting to keep leading zeros and display country codes — while preserving the true numeric format underneath.

Perfect for contact lists, international phone numbers, or any data that needs formatting without losing its function.
