Step by step

1. 

   Open Settings and tap General

   General is the first row of the group below Battery, after Airplane Mode, Wi-Fi and Bluetooth.

   Done

2. 

   Tap Language & Region

   It is just below Keyboard, in the group that starts with AutoFill & Passwords.

   Done

3. 

   Tap Number Format

   It shows the current format at the right. Ours, set to Germany, showed 1.234.567,89.

   Done

4. 

   Tap a format

   Four formats are listed, each shown with the same example number. The tick shows the active one. Ours was on 1.234.567,89, the German style.

   Done

5. 

   Check the example

   After we tapped 1,234,567.89, the Number Format row showed it, and the Region Format Example at the bottom of the Language & Region page changed to 12,345.67 € and 4,567.89.

   Done

If you do not see this option

• Search for it. Open Settings, tap the search field at the bottom and type Number Format. Apple notes that the sections in Settings depend on the iPhone model. Source: Find settings on iPhone
• The format you want is not listed. Our iPhone offered four formats: 1.234.567,89, 1,234,567.89, 1 234 567.89 and 1 234 567,89. Region, at the top of the same page, is a separate setting; ours was Germany. Source: Change the language and region on iPhone

If this does not work

• An app still shows the old format. Close the app and open it again. Websites can format numbers their own way.
• Dates or units did not change. Date Format and Measurement System are separate rows on the same page; ours showed 19.08.26 and Metric.

About this guide

Whether one thousand two hundred and a half is written 1,200.5 or 1.200,5 depends on the country. The iPhone follows its region, and lets you choose the format yourself.

The screenshots are our own, taken on an iPhone 17e running iOS 27.0.1, in dark mode.

Good to know

A Region Format Example at the bottom of the Language & Region page previews your settings.

In short: Settings, General, Language & Region, Number Format.
