ThisEppError
class defines EPP result/error codes and messages. For a complete definitions of EPP error codes and messages, please refer the EPP Specification, June 29, 2001.EPP result codes are based on the Theory of Reply Codes described in Appendix E of [RFC821]. EPP uses four decimal digits to describe the success or failure of each EPP command. Each of the digits of the reply have special significance.The first digit denotes command success or failure. The second digit denotes the response category, such as command syntax or security. The third and fourth digits provide explicit response detail within each response category.
There are two values for the first digit of the reply code:
1yzz Positive completion reply. The command has been accepted and processed by the system without error.
2yzz Negative completion reply. The command was not accepted and the requested action did not occur.
The second digit groups responses into one of six specific categories:
x0zz Protocol Syntax x1zz Implementation-specific Rules x2zz Security x3zz Data Management x4zz Server System x5zz Connection Management
The third and fourth digits provide response detail within the categories defined by the first and second digits. Specific result codes are listed in the table below.
Every EPP response MUST include a result code and a human-readable description of the result code. The language used to represent the description MAY be identified using an instance of the "lang" attribute within the
element. If not specified, the default language is English, identified as "en". A description of the structure of valid values for the "lang" attribute is described in [RFC3066]. A list of valid values for the "lang" attribute is available in [ISO639]. Response text MAY be translated into other languages, though the translation MUST preserve the meaning of the code as described here. Response code values MUST NOT be changed when translating text.
Response text in the table below is enclosed in quotes to clearly mark the beginning and ending of each response string. Quotes MUST NOT be used to delimit these strings when returning response text via the protocol.
Successful command completion responses:
Code Response text in US English ___________________________________
1000 "Command completed successfully" This is the nominal response code for a successfully completed command. This response code MUST be returned in responses for all commands other than for the situations relating to the
, , and commands as described here. 1300 "Command completed successfully; no messages" This response code MUST be returned when responding to a
request command and the server message queue is empty. 1301
This response code MUST be returned when returning a service message to a client. Message text for this response code is a matter of server policy and is not specified by this protocol. 1500 "Command completed successfully; ending session" This response code MUST be returned when responding to a successful
command. Command error responses:
Code Response text in US English ___________________________________
2000 "Unknown command" This response code MUST be returned when a server receives a command element that is not defined by EPP.
2001 "Command syntax error" This response code MUST be returned when a server receives an improperly formed command element.
2002 "Command use error" This response code MUST be returned when a server receives a properly formed command element, but the command can not be executed due to a sequencing or context error. For example, a
command can not be executed without having first completed a command. 2003 "Required parameter missing" This response code MUST be returned when a server receives a command for which a required parameter value has not been provided.
2004 "Parameter value range error" This response code MUST be returned when a server receives a command parameter whose value is outside the range of values specified by the protocol. The error value SHOULD be returned via a
element in the EPP response. 2005 "Parameter value syntax error" This response code MUST be returned when a server receives a command containing a parameter whose value is improperly formed. The error value SHOULD be returned via a
element in the EPP response. 2100 "Unimplemented protocol version" This response code MUST be returned when a server receives a command element specifying a protocol version that is not implemented by the server.
2101 "Unimplemented command" This response code MUST be returned when a server receives a valid EPP command element that is not implemented by the server. For example, a
command MAY be unimplemented for certain object types. 2102 "Unimplemented option" This response code MUST be returned when a server receives a valid EPP command element that contains a protocol option that is not implemented by the server. For example, a server MAY not implement the protocol's session-less operating mode.
2103 "Unimplemented extension" This response code MUST be returned when a server receives a valid EPP command element that contains a protocol command extension that is not implemented by the server.
2104 "Billing failure" This response code MUST be returned when a server attempts to execute a billable operation and the command can not be completed due to a client billing failure.
2105 "Object is not eligible for renewal" This response code MUST be returned when a client attempts to
an object that is not eligible for renewal in accordance with server policy. 2106 "Object is not eligible for transfer" This response code MUST be returned when a client attempts to
an object that is not eligible for transfer in accordance with server policy. 2200 "Authentication error" This response code MUST be returned when a server notes an error when validating client credentials.
2201 "Authorization error" This response code MUST be returned when a server notes a client authorization error when executing a command. This error is used to note that a client lacks privileges to execute the requested command.
2202 "Invalid authorization information" This response code MUST be returned when a server receives invalid command authorization information required to confirm authorization to execute a command. This error is used to note that a client has the privileges required to execute the requested command, but the authorization information provided by the client does not match the authorization information archived by the server.
2300 "Object pending transfer" This response code MUST be returned when a server receives a command to transfer an object that is pending transfer due to an earlier transfer request.
2301 "Object not pending transfer" This response code MUST be returned when a server receives a command to confirm, reject, or cancel the transfer an object when no command has been made to transfer the object.
2302 "Object exists" This response code MUST be returned when a server receives a command to create an object that already exists in the repository.
2303 "Object does not exist" This response code MUST be returned when a server receives a command to query or transform an object that does not exist in the repository.
2304 "Object status prohibits operation" This response code MUST be returned when a server receives a command to transform an object that can not be completed due to server policy or business practices. For example, a server MAY disallow
commands under terms and conditions that are matters of local policy, or the server may have received a command for an object whose status prohibits deletion. 2305 "Object association prohibits operation" This response code MUST be returned when a server receives a command on other objects that are associated with the target object. For example, a server MAY disallow
commands while an object has active associations with other objects. 2306 "Parameter value policy error" This response code MUST be returned when a server receives a command containing a parameter value that is syntactically valid, but semantically invalid due to local policy. For example, the server MAY support a subset of a range of valid protocol parameter values. The error value SHOULD be returned via a
element in the EPP response. 2307 "Unimplemented object service" This response code MUST be returned when a server receives a command to operate on an object service that is not supported by the server.
2308 "Data management policy violation" This response code MUST be returned when a server receives a command whose execution results in a violation of server data management policies. For example, removing all attribute values or object associations from an object MAY be a violation of a server's data management policies.
2400 "Command failed" This response code MUST be returned when a server is unable to execute a command due to an internal server error that is not related to the protocol. The failure MAY be transient. The server MUST keep any ongoing session active.
2500 "Command failed; server ending session" This response code MUST be returned when a server receives a command that can not be completed due to an internal server error that is not related to the protocol. The failure is not transient, and will cause other commands to fail as well. The server MUST end any ongoing active session.
2501 "Timeout; server ending session" This response code MUST be returned when a server receives a command that can not be completed due to a session-oriented timeout.
2502 "Session limit exceeded; server closing connection" This response code MUST be returned when a server receives a
command, and the command can not be completed because the client has exceeded a system-defined limit on the number of sessions that the client can establish. It may be possible to establish a session by ending existing unused sessions.
