# Azure Sphere retirement

Retirement date for the Azure Sphere service: 31 Jul 2031. From that date the service stops supporting customer application, OS, bug and security updates, and DAA certificate issuance.

- Effective date: 31 Jul 2031
- Cloud: [Azure](https://eolwatch.dev/cloud/azure.md)
- Service: [Azure Sphere](https://eolwatch.dev/services/azure/sphere.md)
- Type: Retirement
- Category: [Service](https://eolwatch.dev/categories/services.md)
- Replacement: Not stated by vendor
- Announced: 20 Mar 2026
- Official source: [azure.microsoft.com](https://azure.microsoft.com/updates?id=557123)
- Last checked: 12 Nov 2026

## What breaks

From the retirement date, the Azure Sphere service stops supporting all customer application, OS, bug and security updates, along with DAA certificate issuance. Microsoft asked customers who needed additional MT3620 stock to express OEM license renewal and purchasing intent through the distributor, Avnet, before 31 July 2026.

## What to do

1. Evaluate hardware redesign to replace MT3620 silicon in future product iterations.
2. Consider PSA/SESIP Level 3+, or similar, certified silicon as a guideline for silicon with similar security properties.
3. Evaluate alternative Azure IoT and 3rd-party solutions alongside a new MCU. See the Azure IoT [documentation](https://learn.microsoft.com/azure/iot/) and [solutions](https://azure.microsoft.com/solutions/iot/).
4. For questions, contact your Microsoft accounts team or [Microsoft Support](https://support.microsoft.com/).

## Replacement

Not stated by vendor.
