LINE and PayPay announced phased account linking in July 2026 for transfers, bill splitting, points, and friend-list experiences, subject to user consent.

Verified event

LINE and PayPay announced phased account linking in July 2026 for transfers, bill splitting, points, and friend-list experiences, subject to user consent. The factual reference for this page is the PayPay与LY官方公告.

What changed

Account linking does not let a business infer payment accounts, balances, or spending power from a phone number; LINE Registration Check does not return those fields.

What did not change

LINE Registration Check returns phone number and registration status. A separate demographic task may add user ID, nickname, gender, age, and profile picture. A platform feature update does not create undocumented data capabilities.

How this connects to AIPushAI

For permissioned phone-number workflows, review the actual tasks and fields on the AIPushAI LINE service page. The news context does not expand the product claim.

Operational response

Update internal guidance with region, version, and date. Label beta or gradual rollouts accurately and retain owned landing pages, CRM permission, and opt-out records.

Data and privacy boundary

Do not infer identity, assets, intent, or consent from usernames, presence indicators, AI tools, wallets, or payment links. Keep interface signals separate from exported check fields.

Keep news references current

Retain the 2026 event date and link to the PayPay与LY官方公告. If the feature is in beta or gradual rollout, do not describe it as universal. Update the factual paragraph when availability changes without expanding AIPushAI product claims.

What to review next

Availability can change. Recheck the official source and in-app status before acting, and keep the event date instead of presenting a staged release as a permanent universal state.
