ADDRESS FRESHNESS GUIDE

The hardest part of an address book is what happens after someone moves.

Saving an address is easy. Discovering that it changed six months later is the problem. A better model lets the person who moved maintain the current address themselves.

Keep my addresses current See how OnceAsk works

Addresses change.Freshness is a relationship problem, not a formatting problem.

Static contact cards age silently

Most address books do not tell you that a friend moved. The old address simply remains there until a returned card, awkward text, or failed delivery exposes the problem.

Old data looks valid
Moves are easy to miss
Mailings reveal the error late

Let the person who moved update once

The person who knows the new address best is the person who moved. OnceAsk is built around that owner-maintained source rather than requiring every friend to edit a separate copy.

Recipient-maintained address
One canonical update
Chosen relationships stay current

Keep control with the address owner

Current does not have to mean public. Address sharing should still depend on the relationship and permissions the person chooses.

Private by default
Recipient control
Permission-aware updates

HOW IT WORKS

Ask once. Keep the result useful.

Collect or confirm the current address

Establish the initial mailing-address relationship.

The person moves

They update their own address instead of texting the same change repeatedly.

Authorized relationships use the current version

Future cards, invitations, or gifts start from a better source than an old snapshot.

BUILT FOR PEOPLE + AI

Addresses should be live data, not a stale field in a contact card.

OnceAsk gives people one current address to maintain and gives compatible assistants a permissioned way to resolve or request the delivery information they need.

QUESTIONS

What to know

How do I know when someone in my address book moves?

Traditional address books usually do not know. The most reliable model is to let the address owner update their own current information and share that update with the people they choose.

Should I periodically email everyone to refresh their address?

That can work, but it asks every contact to reconfirm even when nothing changed. A recipient-maintained model lets the person update when a move actually happens.

Does a self-updating address book scrape public records?

OnceAsk does not rely on silently scraping a new home address. The model is based on recipient-confirmed information and sharing choices.
