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