When logging in you may be requested to show all your details including postal address. When giving this information, I suggest you state every figure and letter correctly to protect deliveries. Be very careful with the zip code. Some people mistakenly think they remember well their zip codes, and it turns out later they may be wrong. And it may be a problem if you show even one figure wrong. Here
worldpostalcode.com/united-states/texas/dallas you may recheck it.
