# Subscription period

Available in Classic and VPC

When requesting an Enterprise Certificate, you can select a subscription period of 1, 2, or 3 years. Before the subscription period expires, the same order can be continuously maintained through the extension feature.

              Note

              

- Subscription periods are available only for Enterprise Certificate.
- When using ACME, a single order can be operated over a long period through subscription extension.

## Select a subscription period

You first select a subscription period when requesting [Advanced DV/OV certificate issuance](/docs/en/certificatemanager-issuecertificate/#advanced%EC%9D%B8%EC%A6%9D%EC%84%9C).

| Subscription period | Description |
| --- | --- |
| 1 year | Subscription valid for 1 year from the issuance date |
| 2 years | Subscription valid for 2 years from the issuance date |
| 3 years | Subscription valid for 3 years from the issuance date |

              Note

              

- A subscription period must be selected when requesting issuance in the Certificate Manager console.
- If the subscription period is omitted when applying via Open API, a default of 1 year is applied.

## Extend a subscription

1. In the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Security** > **Certificate Manager** > **Enterprise Certificate** > **Order List**.
2. Select an order.
3. After selecting the order, click **[Extend subscription]**. When the subscription extension page appears, proceed with the following steps:
4. **Select period**: Select an extension of 1, 2, or 3 years.
5. **Confirm**: Click to extend the subscription by the selected period. However, the extension may succeed or fail depending on the extension conditions.

              Caution

              

A valid subscription extension is **billed immediately** upon request. Review the [Extension conditions](/docs/en/certificatemanager-advanced-subscription#%EC%97%B0%EC%9E%A5%EC%A1%B0%EA%B1%B4) and [Billing information](/docs/en/certificatemanager-advanced-subscription#%EA%B3%BC%EA%B8%88%EC%95%88%EB%82%B4) carefully.

### Extension conditions

The extendable period is determined based on the difference between the current **year** and the subscription end **year**. The day is not considered.

| Subscription end year − Current year | Status | Extendable period |
| --- | --- | --- |
| 0 years (same as current year) | Extendable | Up to 3 years |
| 1 year | Extendable | Up to 2 years |
| 2 years | Extendable | Up to 1 year |
| 3 years or more | Not extendable | - |

Example (as of March 12, 2026)

| Current subscription end date | Year difference | Extendable period |
| --- | --- | --- |
| December 31, 2026 | 0 years | 1, 2, or 3 years |
| June 30, 2027 | 1 year | 1 or 2 years |
| January 1, 2028 | 2 years | 1 year |
| January 1, 2029 | 3 years | Not extendable |

              Note

              

- The new subscription end date is calculated by adding N years to the existing subscription end date. (Not recalculated based on the current date)
- There must be no ongoing extension within the same order.

## Billing information

The subscription period is reflected in billing calculations.

| Type | Billing unit |
| --- | --- |
| New issuance | Number of domains × Subscription period (years) |
| Renewal (only when adding domains) | Number of additional domains × Remaining subscription period (years, at least 1 year) (Note) Renewal with the same domain name does not incur charges. |
| Subscription extension | Number of domains × Extension period (years) |

Example 1: New issuance (2-year subscription, 2 single domains, and 3 wildcard domains)

| Domain type | Number of domains | Subscription period | Billable quantity |
| --- | --- | --- | --- |
| Single | 2 | 2 years | 4 |
| Wildcard | 3 | 2 years | 6 |

Example 2: Renewal (domains added; subscription end year: 2029; current year: 2026 → 3 years remaining)

| Domain type | Number of additional domains | Remaining period | Billable quantity |
| --- | --- | --- | --- |
| Single | 1 | 3 years | 3 |
| Wildcard | 1 | 3 years | 3 |

              Note

              

Renewals with the same domain name (CASE 1) do not incur charges.
