What are my street number, number suffix, street type, municipal number or civic number?
You might be asked for your street number, municipal number or civic number on an application form. All of these terms simply mean the number of your house.
A number suffix is a letter that might come after an address if there aren't enough numbers for all the buildings on a street. (For example, if your address is 9A Main Street, the suffix would be "A".)
Street type means "Road" or "Boulevard" or any of the other terms that follow a street name.
