Clean up Google Contacts without losing anyone
Export a backup first, then work from the safest fixes to the riskiest: duplicates you are sure of, missing country codes, work and personal emails, and old jobs last. Google keeps deleted contacts in Trash for 30 days and can undo changes made in the past 30 days, so a careful clean-up can be reversed.

For anyone whose Google Contacts has grown over years of phones, inboxes and events: duplicates, numbers without country codes, people listed at companies they left. The Google steps below are from Google's own help pages, checked on 20 Oct 2026; Google moves its menus from time to time.
1. Start with a backup
Before you change anything, export everything. In Google Contacts on a computer, select your contacts, choose More actions, then Export, and pick Google CSV (Google's export steps (opens in a new tab)). Keep the file somewhere safe. If a clean-up goes wrong, you can import it again.
2. Merge only the duplicates you are sure of
Google Contacts suggests duplicates under Merge & fix, where you can merge them one at a time or all at once (Google's merge steps (opens in a new tab)). Resist Merge all. Accept the pairs that share an email address or phone number, and look harder at the ones that only share a name: two people called Rahul Sharma at different companies are two people.
- Same email or same phone number: almost always the same person
- Same name and same company: probably the same person; check the title
- Same name only: check before merging
- Same person at two companies: keep the current company and note the old one, so you know they moved
3. Add missing country codes
A number saved as 98xxxxxxxx works on the phone where you saved it, and fails when you call from abroad or the contact syncs to a phone in another country. Save every business number in the international format.
- India: +91, and drop the 0 in front of a landline's area code (011 becomes +91 11)
- Japan: +81, and drop the leading 0 (03-1234-5678 becomes +81 3-1234-5678)
- Singapore: +65, in front of the eight-digit number
4. Separate work from personal
Label each email as work or personal, and fill in the company from the work email's domain where it is missing. It makes search, sharing and exports cleaner: you can share only work contacts with a team, or export only business contacts to a CRM.
Shared inboxes such as sales@ or info@ are not people. Label them separately, so they do not crowd the people you actually know.
5. Update old jobs last
Titles and companies go out of date fastest, and they are the riskiest to change: a wrong update overwrites something that was right. Check against a public source you trust, such as the company's own site or the person's own profile, note the date you checked, and keep the old company as a note.
6. Leave these alone
- Contacts you cannot place: put them in a label such as "To check" instead of deleting them. Deleting is the step that is easiest to miss and, after 30 days in Trash, impossible to undo
- A work account managed by your company: ask your Google Workspace administrator before bulk changes
- Anything you have not backed up today
With Meishio
Doing this in Meishio
Meishio follows the same order and changes nothing in Google until you approve it. Connect Google Contacts and run the address-book check: Meishio finds duplicates for you to confirm, business numbers without a country code, companies from work email addresses, and work versus personal emails.
- Meishio never deletes the contacts already in your Google account
- Sending edits back to Google starts off; you approve each fix, and each one can be undone
- Entries that look like shared inboxes or test data are set aside for you to decide
- Old jobs are checked only when you start a check; each finding shows its source and date, and nothing changes until you accept it
Questions
Does merging contacts in Google Contacts delete anything?
Merging combines two entries into one, and Google says you can separate a contact that you merged. To be safe, export a backup before you merge in bulk.
How long can I recover deleted Google contacts?
Deleted contacts stay in Trash for 30 days. Settings → Undo changes can also restore your whole list to a time in the past 30 days, but contacts added after that time won't show up, so export your current contacts first.
Should I clean up Google Contacts on my phone or a computer?
On a computer, at contacts.google.com. Google's export and Undo changes steps are written for it, and a big screen makes duplicates easier to compare.
Can Meishio clean up Google Contacts for me?
It finds what needs fixing and suggests each fix: duplicates, missing country codes, companies from work emails, work and personal emails. You approve what goes back to Google, each fix can be undone, and Meishio never deletes the contacts already in your Google account. More questions about Meishio →
