I would need a wider range of sample data than for just one record - samples representing the whole range of possibilities would be required. The one you posted has only three address lines. If, for example, some letters go to people in companies or outside the US, I imagine you could have as many as eight address lines:

Addressee Name
Position/Title
Division/Branch
Company Name
Floor/Room/Unit Building Name
Street Address
City, State Zip
Country
