Your contact fixes their number — and it appears in your Google Contacts

Think about where a phone number really has to be correct: not in a system you log into, but in the address book on your phone — the one that rings when they call, the one you tap to call them back. That is also the book that goes stale fastest, because nobody re-keys a contact they saved two years ago.

CentralContacts syncs into your real Google Contacts, so the number in your pocket stays right on its own.

One click into your real address book

Connect Google once. From any contact in CentralContacts, ‘Add to Google Contacts’ writes them straight into your actual address book — name, number, company, the lot — no export, no CSV, no copy-paste.

Then it keeps that contact current

This is the part that matters. When you edit a linked contact in CentralContacts, the change mirrors to Google automatically — no button to press. And when the contact maintains their own record and changes their number, that new number flows through to the Google contact on your phone, with their consent. You didn’t chase it. You didn’t re-key it. It was simply right the next time you looked.

A number a person maintains for themselves, arriving in the address book that actually rings. That’s the whole point of the estate, made concrete.

Careful by design

• Linked-only. It updates contacts you’ve deliberately linked — it never bulk-writes your whole book or creates people you didn’t add.
• Consent-gated. A contact’s details only propagate where they’ve agreed to it, and they can revoke that at any time.
• Yours to keep. You still hold your own record of the relationship, even if they later opt out.

Where to start

Connect Google Calendar and Contacts from your dashboard, add a few important contacts to your Google address book, and invite the ones whose numbers you can’t afford to lose to keep their own card current. From then on, the book in your pocket looks after itself.
