Submitted information is researched and verified before being included in our database.
It can be up to 60 days for the information to appear online, depending on when you sent us the info and the time of the next update after we research it. The listings undergo regular updating as the information becomes available. More specific prefix location information is added as we deem appropriate. The final decision as to the listed location name is ours.
