Hi Jarodrigus,

Thank you for participating in the Apple Support Communities. We understand you're unable to AutoFill phone numbers using Safari. Just to confirm, are these the steps you're following? Automatically fill in your information in Safari on iPhone.

"In the Safari app, use AutoFill to automatically fill in credit card information, contact information, and user names and passwords.

Set up AutoFill

You can save your personal information or credit card number on your iPhone to speed up filling in online forms and making purchases.

1. Go to Settings  > Safari > AutoFill.
2. Do any of the following:

• Set up contact info: Turn on Use Contact Info, tap My Info, then choose your contact card. The contact information from that card is entered when you tap AutoFill on webpages in Safari.
• Set up credit card info: Turn on Credit Cards, tap Saved Credit Cards, then tap Add Credit Card. Enter your credit card information into the fields provided or tap Use Camera to enter the information without typing.

You can also save the credit card information when you make an online purchase. See Make your passkeys and passwords available on all your devices with iPhone and iCloud Keychain.

Fill in your contact information automatically

2. Tap AutoFill Contact above the keyboard, then select a contact.
3. Tap any field to make changes.
