Advanced certificates allow selection of a subscription period (1 year / 2 years / 3 years) when requesting issuance. Before the subscription period expires, the same order can be continuously maintained through the extension feature.
- The subscription period feature is available only for Advanced certificates.
- When using ACME, a single order can be operated over a long period through subscription extension.
Select subscription period
The subscription period is initially selected when requesting Advanced certificate issuance.
| 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 |
- 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.
Subscription extension procedure
- From the NAVER Cloud Platform console, navigate to Menu > Services > Security > Certificate Manager > Certificate List, then click the Advanced certificate tab.
- Select an order.
- After selection, click Subscription management > Extend subscription. When the subscription extension interface appears, proceed with the following steps:
- Select period: Select the extension period (1 year, 2 years, or 3 years).
- Confirm: Click to extend the subscription period by the selected duration. However, the extension may succeed or fail depending on the extension conditions.
A valid subscription extension is billed immediately upon request. Review the Extension conditions and Billing information 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 year / 2 years / 3 years |
| June 30, 2027 | 1 year | 1 year / 2 years |
| January 1, 2028 | 2 years | 1 year |
| January 1, 2029 | 3 years | Not extendable |
- After extension, 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: New issuance (2-year subscription, 2 single domains, 3 wildcard domains)
| Domain type | Number of domains | Subscription period | Billable quantity |
|---|---|---|---|
| Single | 2 | 2 years | 4 |
| Wildcard | 3 | 2 years | 6 |
Example: Renewal (domain addition, subscription end: 2029 / Current: 2026 → remaining 3 years)
| Domain type | Number of additional domains | Remaining period | Billable quantity |
|---|---|---|---|
| Single | 1 | 3 years | 3 |
| Wildcard | 1 | 3 years | 3 |
Renewals with the same domain name (CASE 1) do not incur charges.
