IsValid

Checks if a mobile telephone number is valid and live and returns some information about the subscriber.

To connect to this service you'll need to use one of these endpoints:

JSON

Open API

SOAP

Description

Checks a mobile telephone number for validity and returns some information about the subscriber.

If the telephone number is not supplied in full international format, the service will assume it is a UK number by default. This can be overridden by supplying an appropriate value for the DefaultCountryCode option.

This service is not appropriate if you require indication about any number other than a mobile number. In those circumstances, you should consider the use of the PhoneValidation service.

This service is deprecated in favour of the PhoneValidation service. This service will remain operational for the foreseeable future, but the PhoneValidation service should be used for all new development.

Note that cellphone numbers within North America are validated only to the extent provided by the international telephone validation service due to technical restrictions within the mobile network.

Credit Usage

Each request to this method consumes 1 MobileValidation credit.

Parameters

The following parameters can be supplied to this method

username	username See the available authentication methods. If you are using username & password authentication, specify the username to authenticate as. If you are using API Key authentication and you are not using the JSON, Javascript or ADO APIs, use your API Key here with the prefix `apikey-`, e.g. `apikey-ABCD-1234-EFGH-5678`
password	password If you are using username & password authentication, specify the password to use for authentication. Otherwise leave this blank.
number	number The telephone number to validate
options	options An array of options that control further details of how this method operates. See the Advanced Options section below for more information.

Advanced Options

The following options can be specified as part of the option parameter. Each option is specified as a key/value pair. The list of available names is shown below, along with a description of the allowable values for that name.

Common Options
Name	Description
ApplicationName	ApplicationName Gives the name of the calling application - used to break down usage by application in the usage reports on the dashboard
Service-Specific Options
Name	Description
DefaultCountryCode	DefaultCountryCode Sets the international dialling code prefix to use by default for any numbers given in local format, e.g. "1" for North America, "49" for Germany etc.
AllowedPrefixes	AllowedPrefixes A comma-separated list of prefixes in standard international format that the number must start with to be treated as valid. For example, use "+447" to allow only standard UK mobile numbers.
BarredPrefixes	BarredPrefixes A comma-separated list of prefixes in standard international format that will cause the number to be treated as invalid. For example, use "+90,+447781" to block any Indian numbers or numbers allocated to C&W Guernsey.

Results

This method returns an object containing the following fields:

Status	Status Indicates whether the method call was successful, or if some error occurred. If the `Success` field is `true`, the other results described below can be used to get the results of the method. If `Success` is `false`, some error occurred in calling the method, such as the authentication failed or the account is out of credits. The details of the error can be obtained from the `ErrorMessage` field, and any other results should be ignored
Result	Result The status of the mobile telephone number query. This can be one of the following values: `Success` - subscriber available `Unavailable` - subscriber has a temporary error `Invalid` - subscriber has a permanent error `TimedOut` - the query did not return within the time `Error` - an unknown error occurred In general, `Success` means the number will ring/receive a text message, `Unavailable` indicates the number is valid but the phone is switched off or out of reception, while `Invalid` means the number is not allocated
CountryISO	CountryISO The ISO 3-character code of the country the mobile telephone originates from
Organisation	Organisation The telco the telephone is registered with
NetworkName	NetworkName The network which the telephone is registered to
NetworkType	NetworkType The type of network the telephone is registered to. NB: This property is not always populated.
Ported	Ported Indicates if the telephone has been ported between networks
PortedFromOrganisation	PortedFromOrganisation If the number has been ported, indicates the organisation the telephone was originally registered with
PortedFromNetwork	PortedFromNetwork If the number is ported, indicates the network the telephone was originally registered to
LocationISO	LocationISO The ISO 3-character country code that the mobile is currently located in
