Call-only ads deprecated: creation blocked from January 2026, serving ends February 2027

Google is retiring the call-only ad format (built on the legacy ETA framework). With v23 in January 2026, creating or duplicating call-only ads is blocked in all API versions, the UI, Editor and SA360; existing ads keep serving and remain editable until February 2027, when all call-only ads stop and API support is removed.

Migration path: create responsive search ads and attach call assets (phone numbers as assets at customer, campaign or ad group level). Key dates: January 2026 creation blocked; until February 2027 existing ads serve and can be updated; February 2027 full removal.
