The Sample Code is Giving Strange Errors or is Crashing!

Most likely, the sample code cannot connect to Service Objects. Many environments will not allow you to connect out on port 80 or will clip out XML data from these requests/responses.

The easiest way to check for this is to open a browser on the machine running the sample code. In your browser, navigate to:

Then try to run one of the operations with your trial key. If you get a browser error or get no data back, then the sample code isn't able to connect, either. Contact your systems administrator to resolve why you are not able to connect to Service Objects.

Phone Append 2 doesn't find any data for my information!

If your phone number is unlisted, by law, it cannot be found by searching by contact information. Additionally, if your number is for a cellular phone, Phone Append 2 cannot find your information.

Can PA2 return phone numbers associated with PO Box addresses?

If a matching name and PO Box address is sent to the service, it can return the number associated with that input information. The sample data we offer on our website will have some examples of PO Boxes that return phone number matches.

Phone Append 2 did not return an address with the phone number!

Some addresses are not entered correctly and not all providers standardize their data, so the service will attempt to correct any mistakes and standardize the addresses before returning a result. In some rare cases, however, the addresses cannot be corrected to meet USPS standards. Instead of returning a bad address the service will instead return the phone with the data it has available and omits the portions of the address that could not be corrected.

Phone Append 2 is giving someone else's phone number for my information!

Phone Append 2's data is updated constantly. In the case that you just changed your number, it probably just has not been updated since you made the change. Sometimes phone companies take their time in publishing updates. If the information is not accurate, and the given phone number has not recently changed ownership, please let us know at

Can Phone Append 2 give me the information for a disconnected number?

No, although we are working on procuring this information. If you are interested in using this data, please contact us at, and we will let you know when that has been implemented.

Can Phone Append 2 give me the information for a cell phone or wireless number?

No. This information was somewhat restricted until recently, and even those databases that are currently available do not cover every wireless number in the US. We are also in the process of procuring this information and will keep you updated if you are interested.

Can Phone Append 2 give me the information for a Canadian phone number?

Yes – sometimes. Our data set for Canada isn't as extensive as our dataset for the US, but Phone Append 2 returns information for Canadian phone numbers.
