If there is an issue with a command or an operation submitted to one of our domain management tools, you will receive an error message. There are several types of error messages that you may receive:
  • Fatal error
    Receiving a fatal error means that the command (or operation) you submitted was not successful and changes were not made to the registry. The Automaton, EPP and the Web Domain Manager can produce fatal errors which can be identified by the letter "V" followed by three numbers. e.g. V028. Fatal errors can often be addressed by making a minor change to your request.

  • Non-fatal error
    These are warning messages and can be appended to successful commands and operations.  Even though your command or operation was successful, a non-fatal error warns you that there is an issue that could prevent you from performing future commands or operations.

Fatal errors

Error Code
Description
V001 Subject Line contains unknown action The Automaton checks each message's subject line to determine what action to take with the request.   If this does not correspond to one of the possible actions it returns this error.  Details of the correct subject line can be found in the documentation for each operation.
V002 Nominet have notified you that any further applications to register new domain names will be refused. The tag you have used is not currently active.  Please contact our Member and Registrar Support team on +44 (0)1865 332233 for further information.
V007 Unknown field '<xxx>' A template is given for each of the Automaton requests in the documentation for the operation type.  Any fields given which do not appear in the template will not be recognised and will cause the Automaton to abandon processing the request with this error.
V008 No Domain name given This error occurs if you perform an operation on a domain, such as renew, but either do not include the 'key' field or a value within it. 
V009 Domain <xxx> cannot be requested via this automaton Our systems will only accept requests for .uk domains under our defined second levels.  This error will occur if you request a domain that we either do not administer or includes an additional prefix such as 'www.'.
V010 Domains with two letters are not allowed Third level domains under co.uk, me.uk, net.uk and org.uk cannot consist of two letters.  For further information please see clause 5.6 of our registration rules.
V011 Domains with one character are not allowed Third level domains under co.uk, me.uk, net.uk and org.uk cannot consist of just one character.  For further information please see clause 5.5 of our registration rules.
V012 Fully-qualified domain names must be no longer than <xxx> characters The maximum length of a registration up to and including .uk is 64 characters.  For further information please see clause 5.7 of our registration rules.
V013 The account name field cannot be modified Changes to the organisation name on a registrant contact (the registrant for the domain name) can only be made by a registrant transfer or by our support staff in the case of minor corrections.
V014 The tag '<xxx>' has been barred from creating or retagging domains. The tag used is currently barred from performing this action.  Please contact our Member and Registrar Support team on +44 (0)1865 332233 for further information.
V015 The tag '<xxx>' has been barred. The tag used is currently barred from performing any actions.  Please contact our Member and Registrar Support team on +44 (0)1865 332233 for further information.
V016 The tag '<xxx>' is unrecognised This error occurs when an invalid tag is used in the 'registrar-tag' field, often due to the tag not being provided in capital letters.
V017 bad value for `first-bill' field (must be either `th' or `bc') The 'first-bill' field can only be set to either 'th' or 'bc' ('NULL' to clear).
V018 bad value for `recur-bill' field (must be either `th' or `bc') The 'recur-bill' field can only be set to either 'th' or 'bc' ('NULL' to clear).
V019 Missing account name The 'account-name' field is mandatory when creating a new account.  It specifies whom the registrant contact (and domain names) is registered for and cannot be modified by the registrar at a later date.
V020 Missing or invalid account identifier Operations relating to a specific registrant contact must include the account-id number.
V023 Error Reading Nameserver <xxx> This error occurs when invalid information or characters are provided in the name server details.
V024 Missing glue record for server <xxx> When a name server is provided that is the child of the domain supplied in the request, it is necessary to create a glue record by including its IP address.
V025 Bad IP address for server <xxx> : <xxx> An IP address will be treated as invalid if it:
Starts with 0, 10, 127, 192.168.
Starts within 172.16 to 172.32.
V027 Bad value for `type' (must be one of LTD, PLC, PTNR, LLP, STRA, IND, OTHER, FCORP, FOTHER, RCHAR) Please see our registrant types page for full details regarding the 'type' field.
V028 Invalid country code for <xxx> (must be the two-letter ISO 3166 country code) The country code used in the 'country' field must be a valid two-letter country code from ISO 3166
V029 Invalid postcode: <xxx> Postcodes are validated to verify that they are formatted correctly.  If you follow the postcode guidelines from GovTalk, the postcode should be accepted.
V030 <xxx> field is too long (<xxx> is maximum) Most fields have a limit of 200 characters, the exceptions being:
'co-no' up to 50 characters.
'addr' up to 3 lines of 255 characters.
'notes' up to 15 lines of 256 characters.
V036 Too many nameservers specified (10 is maximum) You can only provide a maximum of 10 name servers for a registration.
V040 Bad month '<xxx>' specified for list action (Must be of form CCYY-MM) The format of the month field must be Year-Month, for example March 2007 is 2007-03.
V044 Unrecognised PGP format The most common reason for this error is sending an automaton request in MIME/HTML format. This causes a duplicate message to be sent in the Automaton request. This error can also happen when:
  • The Automaton request has been PGP signed more than once
  • There is corruption to the ASCII armor that surrounds the PGP message and signature
V045 Error occurred during PGP decode This error can be caused by a corruption of the PGP signature or the surrounding ASCII armor lines, these being:

-----BEGIN PGP SIGNED MESSAGE-----
-----BEGIN PGP SIGNATURE----
-----END PGP SIGNATURE----

This may be due to the wrong method being used when signing the message, errors copying the message to an email after generation, or by the email client modifying the message.

If using PGP 9 or above, please also check that the Hash algorithm is set to SHA-1.  The hash setting should be displayed at the top of a signed message and can changed within the PGP program by double clicking on your key and selecting edit from the hash drop down menu.
V046 Message not in Clear Text Signed Format This error occurs when the message received by the Automaton has either been encrypted or has not been PGP signed.
V047 Signing Key not recognised This error occurs where the key used to sign the request has not been registered with our system.  It is not possible to determine either the validity of the message or the requestor’s identity. Details on how to add a new key can be found on our PGP registration page.

You may also receive this error if you sign an Automaton request with a PGP key recently added to our system. The Automaton's key update occurs daily around 8pm (GMT).
V048 Signature did not match the text view full description
V049 Key has been revoked The PGP key used to sign the message is no longer valid.  Details on how to add a new key can be found on our PGP registration page.
V050 Key has been disabled The PGP key used to sign the message is no longer valid.  Details on how to add a new key can be found on our PGP registration page.
V051 Key has expired
The PGP key used to sign the message is no longer valid.  Details on how to add a new key can be found on our PGP registration page.
V052 Signature has a timestamp in the future
The Automaton compares the current time with time found in the sender’s PGP timestamp.  The error will occur if the timestamp is more than five minutes fast.  In most cases this issue can be resolved by correcting the system time, date and time zone of the computer used to PGP sign the message.
V053 Duplicate Nameserver found in list Duplicate name servers cannot be provided for the same registration.
V055 You may not retag to NOMINET. The NOMINET tag is reserved for situations where a host has name servers but does not have a tag.  This change can only be made directly by us at the request of the registrant.
V057 Invalid field '<xxx>' for <xxx> operation Occurs if a field name is not valid for the stated operation. This is very commonly caused by the field name starting with a capital letter.
V058 This Request will have no effect The request does not contain any information to act upon.  Often this is caused by lines being ignored due to incorrect field names or a problem with their formatting such as the use of capital letters.
V060 Message contained no requests
Occurs if no fields are present in a request after any invalid text has been removed.
V061 Nameserver '<xxx>' appears to be an IP address An IP address can accompany the name server's host name in cases where a glue record is required, but our systems do not allow the IP address to be provided on its own.
V063 Multiple Instances of Field '<xxx>' found
This error will occur if a field, other than 'addr' or 'notes', is used more than once in a single request.
V064 ISO 3166 Country Code required for <xxx> country. The mandatory value for 'country' field has been omitted.  For a list of valid two-letter country codes, please refer to ISO 3166.
V065 postcode required for GB, GG, JE and IM Country codes for <xxx> address The 'postcode' fields are mandatory if the country codes GB, GG, JE or IM are used in the 'country' field. 
V069 '<xxx>' field missing or empty No data has been provided for a mandatory field in a registration request.
V070 Missing admin address No data has been provided for the mandatory 'addr' address field in a registration request.
V071 Missing admin contact No data has been provided for the mandatory primary administrative contact in a registration request

This request would cause you to exceed your advised credit limit and any tags associated with your account are now suspended until further payments have been received. Therefore, you are no longer able to make any new registrations or renewals.

Please contact our Member and Registrar Support team on +44 (0)1865 332233 as a matter of urgency to place an amount of money on your account or log on to your online account to pay any overdue invoices.
V089 Incorrect PGP constructs The Automaton expects a single instance of each of the three PGP construct lines.  This error can occur if your message is sent in MIME/HTML format or if there is an attachment in your message.
V094 Domain name exists already This error occurs if you attempt to register a domain that is already registered. 
V096 Domain name is not registered to your tag This error will occur if you attempt to make changes to a domain that is either not on your tag or not registered.
V101 Domain names cannot be detagged in the first month of registration. If you wish to cancel this domain name please refer to http://www.nominet.org.uk/go/automaton - "Cancelling a Registration"

V127 Domain names may not begin xn--  
V128 Domain name is not within its renewal period or cannot be renewed. A domain name can only be positively renewed up to 6 months in advance of the expiry date.  This message will be returned if you send a positive renewal request outside of this 6 month period.

This error can also occur due to a number of Nominet processes,including:
- The registrant of a 'ltd.uk' or 'plc.uk' domain has changed their name
- The registrant has been dissolved
- Domain is scheduled for cancellation

If you have questions about this, please contact  our Member and Registrar Support Team.
V129 Domain names may not be renewed when recur-bill is set to  'bc' When the recur-bill field is set to 'bc', it indicates that you wish Nominet to bill the registrant directly.  In order to positively renew a domain name the recur-bill field needs to be set to 'th'.
V134 Bad value for <xxx> field (must be between 0 and 182) The auto-bill field is used to indicate how many days before expiry you wish to renew a domain name.  You can set an auto-bill field on a domain name with a value between 1 and 182 where the value indicates the number of days before expiry that a domain name will be renewed.
V138 Domain name contravenes naming rules
 
V140 '<xxx>' field may not currently be changed This error will occur when either a modify or bulk operation updating the auto-bill or next-bill fields cannot be processed for all the domain names requested. For the bulk operation, the domain names that cannot be processed are listed. There are three reasons why the operation would fail for a particular domain name:
1. The recur-bill field is set to 'bc'. Auto-bill and next-bill cannot be set in this circumstance.
2. The domain name has expired.
3. The auto-bill or next-bill field must be set more than 1 day before it is due to be processed. For example you cannot set auto-bill or next-bill to 1 if the domain name expires in 2 day.
V141 Account <xxx> does not exist  
V142 Account <xxx> is not on your tag  
V143 Nameserver <xxx> does not exist
 
V144 Nameserver <xxx> is not on your tag   
V145 <xxx> may not be set retrospectively This error can occur if you attempt to set the auto-bill or next-bill fields to a date in the past.  The value in these fields must be a date in the future.  If the expiry date has passed but you wish to renew the domain name, then you can submit a renewal request.
V146 Contact <xxx> does not exist  
V147 Contact <xxx> is not on your tag  
V148 Both in-line and ? objects present.  
V149 Bad IPV6 address for server <xxx> : <xxx>  
V150 Domain name labels must not be longer than 63 characters  
V151 Domain name has been paid for
 
V154 Invalid registrant identifier <xxx>  
V156 Domain name has already been renewed.  
V157 Auto-bill and next-bill cannot both be set.  
V158 operation: field does not match subject This error occurs if the operation in the subject line of the email and the 'operation' field do not match.  This error can also occur if you use capital letters in the 'operation' field.
V159 Signature has a timestamp more than 3 days in the past The Automaton compares the current time with the message sender’s time found in the PGP timestamp.  The error will occur if the timestamp is more than 72 hours slow. This can usually be resolved by correcting the system time, date and time zone of the computer used to PGP sign the message.
V166 More than one ipv<xxx> address given for name-server  
V169 Missing 'operation' field  
V171 Name server is more than 255 characters  
V172 Name server <xxx> is invalid - label has invalid length  
V173 Name server <xxx> is invalid  
V174 Domain name has already been renewed once in the last 24 hours

V175 You have exceeded cancellation usage limits  
V178 next-bill or auto-bill cannot be set when recur-bill is 'bc'
 
V180 You must accept or reject the registrar change authorisation request This error occurs if an invalid response is given to a registrar change authorisation request.  Please refer to the registrar change authorisation request for possible valid responses.
V181 You cannot accept or reject the registrar change case-id <xxx> You have tried to accept a case-id that doesn't exist or has expired.

V191 Invalid ID prefix '<xxx>', expecting '<xxx>' An invalid contact, nameserver or account identifier has been provided.
V194 Operation blocked by Nominet process This request cannot be made due to a Nominet process.  This can occur for a number of reasons, including:
- The registrant of a 'ltd.uk' or 'plc.uk' domain has changed
- The registrant has been dissolved
- Domain is scheduled for cancellation

If you have questions about this, please contact  our Member and Registrar Support Team.
