Gmail Contacts Not Syncing

What Does This Error Mean?

Gmail contacts stop syncing when contact sync is turned off in your phone settings or the Google Contacts app needs a manual refresh. This usually affects autocomplete suggestions in Gmail and contacts not appearing on a new device. Toggling sync off and on again fixes most cases within minutes.

Affected Models

Gmail Android App
Gmail iOS App
Gmail Web
Google Contacts App
All Google accounts

Common Causes

Contact sync disabled in Android account settings
Google account not given Contacts permission on iPhone
Gmail app cache corrupted, preventing sync from completing
Google Contacts app not refreshed after adding new contacts
Multiple Google accounts on the device causing sync to pull from the wrong account

How to Fix It

On Android, go to Settings > Accounts > Google > your account, and make sure Contacts sync is toggled on.

This is the most common cause — a system update or battery saver setting can disable individual sync items.
On iPhone, go to Settings > your name > iCloud and make sure Contacts is enabled, or Settings > Mail > Accounts > your Google account and turn on Contacts.

iCloud and Google contacts are separate systems; only enabling Google sync inside the Gmail app will sync to Google Contacts.
Open the Google Contacts app and pull down to force a manual refresh.

Automatic background sync can sometimes stall — a manual pull triggers an immediate sync.
In Gmail app settings, go to your account and clear the app cache, then reopen Gmail.

A corrupted cache prevents autocomplete and contact data from updating even when sync is working.
Visit contacts.google.com on a browser and check if the contacts appear there.

If contacts show on the web but not on your phone, the issue is device-side sync, not your Google account.

When to Call a Professional

Contact sync issues are almost always self-service and do not require professional support. If contacts vanish entirely from all devices and Google Contacts web, use the Undo Changes feature at contacts.google.com to restore them. For Google Workspace accounts, check with your administrator whether contact directory sync is enabled.

Frequently Asked Questions

Why do my Gmail contacts not show up on my new phone?

New phones require you to sign into your Google account and enable Contacts sync in the account settings. Once sync is enabled, contacts usually appear within a few minutes.

Can I recover contacts I accidentally deleted from Gmail?

Yes — go to contacts.google.com, click the three-line menu, and choose Undo Changes. Google keeps a 30-day restore point so you can roll back accidental deletions.

Why does Gmail autocomplete not suggest my contacts?

Gmail autocomplete uses your contacts and previous recipients. If sync is off or the app cache is corrupted, suggestions stop working even when contacts exist in your Google account.
