--- title: Check domain transfer eligibility --- [Skip to content](#_top) [API Reference](https://developers.cloudflare.com/api/typescript) [Registrar](https://developers.cloudflare.com/api/typescript/resources/registrar) Copy Markdown Open in **Claude**Open in **ChatGPT**Open in **Cursor** --- **Copy Markdown****View as Markdown** # Check domain transfer eligibility client.registrar.transferCheck(RegistrarTransferCheckParams {account\_id, domains } params, RequestOptionsoptions?): [RegistrarTransferCheckResponse]() {domains } POST/accounts/{account\_id}/registrar/domain-transfer-check Performs real-time, authoritative eligibility checks directly against needed requirements. Use this endpoint to verify a domain is available before attempting a transfer via `POST /registrations/:domain_name/transfer-in`. **Note:** This endpoint uses POST to accept a list of domains in the request body. It is a read-only operation — it does not create, modify, or reserve any domains. ### Behavior - Maximum 10 domains per request - Pricing is only returned for domains where `transferable: true` - Results are not cached; each request queries the registry & other needed upstreams ## Extension Support All `.uk` extensions (`.uk`, `.co.uk`, etc) do not support auth codes. As such, Cloudflare will ignore the `auth_code` section of this request for `.uk` domains. This means that a `.uk` domain depends on public data to obtain domain information, so it might be a few minutes outdated. ### Workflow 1. Call this endpoint with domains the user wants to transfer. 2. For each domain where `transferable: true`, present pricing to the user. 3. For each domain where `transferable: false`, present reasons to the user 4. Proceed to `POST /registrations/:domain_name/transfer-in` only for the `transferable: true` domains. ##### Security

API Token

The preferred authorization scheme for interacting with the Cloudflare API. Create a token. **Example:**Authorization: Bearer Sn3lZJTBX6kkg7OdcBUAxOO963GEIyGQqnFTOFYY

API Email + API Key

The previous authorization scheme for interacting with the Cloudflare API, used in conjunction with a Global API key. **Example:**X-Auth-Email: user@example.com The previous authorization scheme for interacting with the Cloudflare API. When possible, use API tokens instead of Global API keys. **Example:**X-Auth-Key: 144c9defac04969c7bfad8efaa8ea194

RegistrarTransferCheckResponse {domains } Contains the transfer eligibility results.

domains: Record<string, TransferableResult {pricing, transferable, name, reasons } | NonTransferableResult {transferable, name, pricing, reasons } > Maps domain names to transfer eligibility results. Each value contains name, transferable, and reasons.

One of the following:

TransferableResult {pricing, transferable, name, reasons }

pricing: Pricing {currency, renewal\_cost, transfer\_cost } Provides annual pricing information for a given domain. The API returns all per-year prices as strings to preserve decimal precision. renewal_cost and registration_cost or transfer_cost are frequently the same value, but may differ due to premium rates for certain domains. For a multi-year operations, the operation’s cost applies to the first year and renewal_cost applies to each subsequent year. The values reflect the current registry rate, which can change over time.

currency: string ISO-4217 currency code for the prices (e.g., “USD”, “EUR”, “GBP”). Link to this property renewal\_cost: string Per-year renewal cost for this domain. Applied to each year beyond the first year of a multi-year registration, and to each annual auto-renewal thereafter. May differ from registration_cost, especially for premium domains where initial registration often costs more than renewals. Link to this property transfer\_cost: string The first-year cost to transfer this domain. Link to this property

Link to this property transferable: true Link to this property name?: string The check evaluates this domain name. Link to this property

code: "extension\_not\_supported\_via\_api"| "extension\_not\_supported"| "domain\_premium"| 14 more Transfer eligibility reason code. - extension_not_supported_via_api: This API excludes the extension; dashboard flows support it. - extension_not_supported: Cloudflare Registrar excludes the extension. - domain_premium: This API currently excludes premium transfers. - extension_disallows_transfer: Extension currently blocks transfer operations. - domain_not_exists: No registration record exists for the domain. - domain_on_cloudflare: Cloudflare already serves as the domain’s registrar. - domain_locked: Losing registrar reports transfer-prohibited lock status. - registry_status: Registry status currently blocks transfer (for example, pending transfer or deletion state). - domain_outside_transfer_window: Domain is within a transfer wait window (for example, recently registered). - domain_max_term: Completing transfer would exceed the registry maximum term. - invalid_auth_code: The provided auth code is incorrect. - invalid_auth_code_format: Auth code fails Base64 validation. - dnssec_enabled: DNSSEC is enabled. It must be disabled before transfer. - zone_not_found: The target account lacks a Cloudflare zone for the domain. - zone_status_invalid: The Cloudflare zone cannot transfer in its current state. - invalid_zone_plan: The zone plan fails transfer requirements. - domain_unsupported: This endpoint rejects the domain name format.
