No one can blow this one, right? Don't be too sure. With the stress of moving, the number of potential properties considered and how busy people are when moving, mistakes occur more often than you might think.
Start by verifying your new address with your landlord or realtor. Double-check the house or apartment number and the spellings of the street and city. If moving into new construction, make sure the developer didn't change the street name from what was originally filed.
Find out how the post office codes your mail. Check street and city names against what you have. This will also give you the opportunity to obtain your zip + 4 code if you don't already have it. By using zip + 4, your mail will be delivered faster and more accurately.
The basic step of verifying your address will reduce errors and save you time. It will also save you the embarrassment of having to make your address changes twice.
