While your organization may have:
You have the option to keep the one you entered

Reasons why a contact's donor information may vary in your TntMPD database vs. your organization's database
| • | (Most likely) Your donor's address information is slightly different from the way you entered it. In the United States, for example, all addresses are in a national postal service database, which organizations verify against to make sure they are addressed correctly (this is required to receive bulk mailing discounts). The difference may be as simple as 123 Maple Street (the way you typed it) vs. 123 Maple St (the Postal Service official address). Also, the U.S. Postal Service has extended postal codes for addresses which are not normally used when someone asks for your postal code. |
