We'll use the [ValidateNumber](doc:rest-pnv-validatenumber) method on the Phone Number Validation API to do this.\n\nFirst, we'll define the response type for the ValidateNumber method.\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\": \"package com.dynmark;\\n\\nimport com.fasterxml.jackson.annotation.JsonIgnoreProperties;\\nimport com.fasterxml.jackson.annotation.JsonProperty;\\n\\n:::at:::JsonIgnoreProperties(ignoreUnknown = true)\\npublic class ValidateNumberResponse {\\n\\t\\n\\[email protected](\\\"NumberStatus\\\")\\n\\tprivate int numberStatus;\\n\\t\\n\\[email protected](\\\"NormalisedNumber\\\")\\n\\tprivate String normalisedNumber;\\n\\t\\n\\tpublic int getNumberStatus() {\\n\\t\\treturn numberStatus;\\n\\t}\\n\\tpublic void setNumberStatus(int numberStatus) {\\n\\t\\tthis.numberStatus = numberStatus;\\n\\t}\\n\\tpublic String getNormalisedNumber() {\\n\\t\\treturn normalisedNumber;\\n\\t}\\n\\tpublic void setNormalisedNumber(String normalisedNumber) {\\n\\t\\tthis.normalisedNumber = normalisedNumber;\\n\\t}\\n}\",\n      \"language\": \"java\"\n    }\n  ]\n}\n[/block]\nNext we'll add a ValidateNumber wrapper function that calls the [ValidateNumber](doc:rest-pnv-validatenumber) method and returns the NumberStatus value:\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\": \"\\tprivate static int ValidateNumber(String phoneNumber) throws UnirestException, IOException {\\n\\t\\tHttpResponse<String> response = \\n\\t\\t\\t\\tUnirest.post(\\\"https://services.dynmark.com/webapi/phonenumbervalidation/validatenumber\\\")\\n\\t\\t\\t\\t.header(\\\"content-type\\\",

ValidateNumberResponse.class);\\n\\n\\t\\t\\treturn body.getNumberStatus();        \\t\\n\\t\\t}\\n\\t\\tif (response.getStatus() == 401)\\n\\t\\t{\\n\\t\\t\\tSystem.out.println(\\\"Your username and

 ]\n}\n[/block]\nNow we'll wrap the SendMessage code from the [Send SMS Messages](doc:qs-java-send-sms-messages) quickstart in a function\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\":

202)\\n\\t\\t{\\n\\t\\t\\tMessageResponse[] body = objectMapper.readValue(response.getBody(), MessageResponse[].class);\\n\\n\\t\\t\\tif (body[0].isSuccessful())\\n\\t\\t\\t{\\n\\t\\t\\t\\tSystem.out.println(\\\"We sent you a message.\\\");\\n\\t\\t\\t\\treturn true;\\n\\t\\t\\t}\\n\\t\\t\\telse\\n\\t\\t\\t{\\n\\t\\t\\t\\tSystem.out.println(\\\"Sorry, we couldn't send you a message.\\\");\\n\\t\\t\\t\\tfor (ApiValidationFailure failure :

response.getStatus());\\n\\t\\t\\treturn false;\\n\\t\\t}\\n\\t}\",\n      \"language\": \"java\"\n    }\n  ]\n}\n[/block]\nFinally, add a *main* function to code to call the *ValidateNumber* function and report back the result before sending the message:\n[block:code]\n{\n  \"codes\": [\n    {\n      \"code\": \"\\tpublic static void main(String[] args) throws UnirestException, IOException
