Check command

The <epp:check> command is used to determine if an object can be provisioned within a registry and provides a hint to determine if a <create> command would be successful.

<enum:check> element

The <enum:check> element contains the following child elements:

• An <enum:E164Number> giving the first number in the range to be checked.
  
• An optional <enum:lastE164Number> giving the last number in the range to be checked.

Multiple <enum:check> operations can be performed in a single request by repeating the above sequence.

<enum:check> response

The <resData> element for an <enum:check> command contains a single <enum:chkData> element. This contains a list of <enum:cd> elements; one for each range requested. The <enum:cd> element will have an "avail" attribute determining if the range is available or not and the following sub-elements:

• An <enum:E164Number> giving the first number in the range.
  
• An <enum:lastE164Number> giving the last number in the range.

The "avail" attribute will be "1" if the entire range is available and "0" if any numbers in the range are registered.

Example <enum:check> request

The following <enum:check> commands checks the availability for the ranges +441865332100-+441865332500 and +441865333100-+441865333500 and the single number +441865331105.
