Apple brought back a beloved feature from classic phones with T9 dialing in iOS 18. Users can now quickly call contacts by typing their names using the number keys on the Phone app’s keypad, just like on old flip phones.
T9 dialing merges modern iPhone convenience with classic phone functionality. The system lets users skip scrolling through contact lists by simply pressing the numbers that correspond to the letters in a contact’s name.
The feature works right from the Phone app’s keypad tab. For example, to call “John,” users press 5-6-4-6, with each number representing the letters in the name.
T9 Dialing In iOS: A Complete Guide
After years of Android users enjoying this convenient feature, Apple has finally brought T9 dialing to the iPhone. With the release of iOS 18 in 2024, iPhone users can now quickly find and call contacts without scrolling through their entire address book (source: CNET). Here’s everything you need to know about using T9 dialing on your iPhone.
What Is T9 Dialing?
T9 stands for “Text on 9 keys,” a predictive text technology that originated in the era of physical phone keypads. In the context of modern smartphones, T9 dialing allows you to search for contacts by typing the numbers that correspond to the letters in their name.
How It Works
On a phone keypad, each number key corresponds to multiple letters:
- 2: ABC
- 3: DEF
- 4: GHI
- 5: JKL
- 6: MNO
- 7: PQRS
- 8: TUV
- 9: WXYZ
For example, to find “John,” you would type 5646 (5=J, 6=O, 4=H, 6=N). The Phone app then displays all matching contacts, making it faster to find who you’re looking for (source: iDownloadBlog).
Which iPhones Support T9 Dialing?
T9 dialing is available on all iPhones that can run iOS 18 or later, which includes:
- iPhone XS and newer
- iPhone XR and newer
- iPhone SE (2nd generation and later)
To check your iOS version:
- Go to Settings
- Tap General
- Tap About
- Check your iOS version
If you’re running iOS 17 or earlier, update to iOS 18 to access this feature.

Benefits of T9 Dialing
1. Speed and Efficiency
No more scrolling through long contact lists—just type a few digits and find who you need instantly.
2. One-Handed Operation
T9 dialing keeps you in the keypad, making it easier to operate your iPhone with one hand while multitasking.
3. Muscle Memory
If you grew up using phones with physical keypads, T9 dialing will feel natural and intuitive.
4. When You Forget Numbers
With T9 dialing, you can call someone just by typing their name into your iPhone’s Phone app—no need to remember phone numbers (source: CNET).
5. Works With Nicknames
If you’ve saved contacts with nicknames or alternative names, T9 searches those too.
Tips for Getting the Most Out of T9 Dialing
1. Organize Your Contacts
For T9 dialing to work effectively:
- Ensure contacts have properly formatted first and last names
- Use consistent naming conventions
- Remove duplicate entries
- Update outdated contact information
2. Use First or Last Names
T9 searches both:
- Type first name digits for casual contacts
- Type last name digits for professional contacts
- The system recognizes both automatically
3. Type Fewer Digits First
Start with just 3-4 digits:
- See what matches appear
- Add more digits if you need to narrow results
- This prevents over-typing
4. Remember Number-Letter Mappings
Familiarize yourself with the keypad layout:
- Common letters like E, A, and T are on keys 3, 2, and 8
- This makes searching for common names faster
- Practice with frequently called contacts
5. Combine With Other Features
T9 dialing works alongside:
- Siri voice commands
- Contact search in the Contacts app
- Favorites list for most-called contacts
- Recent calls list
